This experiment was conducted to study the influence of feeding a natural feed additive, Nigella sativa seeds (NS), at different levels on growth performance, carcass characteristics and economic efficiency of broiler chicks. One hundred and forty unsexed one-day-old Arbor Acres broiler chicks were battery reared in a semi-open house. Chicks were assigned into four treatment groups. Each treatment consisted of seven replicates each replicate contained five birds. The first diet was the control without NS. The second, third and fourth diet were supplied with 0.5, 1.0 and 1.5% Nigella sativa, respectively. Results showed that the addition of NS at 0.5, 1, and 1.5% levels induced higher market body weight and body weight gain compared to the control group. Moreover, NS supplementation significantly (P<0.05) increased ether extract and crude fiber digestibility compared to the control group.
Carcass weight percentage increased (P<0.05) due to feeding NS at different levels ranged between 74.7 to 76.5% compared to the control group (66.4%). In addition, Bursa of Fabricius and heart weight percentages were higher than those of the control group at 1 and 1.5% NS levels. Broiler chicks fed diets supplemented with 0.5% and 1% NS were more economical than the control group. They showed a high increase in total revenue, net revenue and relative economic efficiency percentages. It could be concluded that the addition of NS up to 1% seems to have a positive effect on growth, carcass characteristics and economic performance, moreover, it can be used as a growth promoter feed additive for broiler chicks.

Current research aimed to characterize Sinai chickens genetically by using nine microsatellite genetic marckers. Twenty-eight birds used in the study were randomly collected (12 males + 16 females). Sinai chickens are a mongrel fowl raised by dwellers and farmers in Sinai Peninsula desert areas and chiefly habituated and adapted to fluctuating circumstances in this region. This strain has a small body size, golden neck feather, brown or golden saddle and brown or black feathered tail for males, while females had golden feathered body with some black feathers in tail and neck, red single comb and they have variable plumage color. Nine microsatellites used produced 53 alleles with mean value of 5.88 allel/locus. Averages of observed and expected heterozygosity were 0.174 and 0.773, respectively. Informative content revealed was high overall loci ranging between 0.608 and 0.811 with average value of 0.718. Six out of 9 loci (66.66%) were not in genetic equaliprium. Bottleneck analysis revealed that, under graphical and SMM model analysis, Sinai chickens non-bottlenecked in recent past history. Results insured that, the utilized panel of markers showed their efficiency capturing genetic characteristics of Sinai chickens reflecting the valuable genetic variation in the studied population, enabling future genetic improvement for this strain avoiding inbreeding.

A gross of 180 growing Japanese quail at one day age classified into four groups as follows: a control group (with no additives), antibiotic group (control diet + sub-therapeutic dose of avilamycin, 8 mg/kg diet), ascorbic acid group (control diet + 1g ascorbic /kg diet) and citric acid group (control diet + 40g citric/kg feed) to evaluate the use of organic acids as probable alternate to antibiotic as growth promoter for quail groups. The most important results were:
Both ascorbic and citric acids supplemented to diets of growing Japanese quail improved growth performance as compared with avilamycin and control groups, favoring ascorbic acid.Both ascorbic and citric acid groups had significantly better serum biochemical serum blood lipids indices than either avilamycin or control ones.
Organic acids had significantly higher antioxidant parameters and immune response but lower thiobarbaturic acid- reactive substances values than both antibiotic and control groups.Fortunately, Organic acids showed to increase of beneficial (Lactobacillus) moreover reduced numbers of harmful bacteria (E. coli and Salmonella) as compared to the control.Females had better performance than males having heavier body weight at 38d, body weight gain, faster growth rate, better feed conversion, higher performance index during the 10-38 period and surpassed males in giblets absolute. However, sex insignificantly affected all slaughter parameters, carcass chemical composition, serum biochemical indices-except cholesterol, antioxidant parameters, immune response and intestinal microflora count.
Therefore, organic acids seemed to be used as growth promoters alternatives to antibiotics in growing Japanese quail.

The experimental work was carried out during the period from February to April 2016 to determine the effects of inclusion Spirulina platensis over the broiler diets on productive performance and some physiological responses. The total number of birds (200 Cobb broiler chickens at seven d of age) were distributed randomly into five treatments (40 chicks each), and each treatment contained four replicates of ten chicks being, a commercial basal diet (control group), while the other groups were supplemented with Spirulina platensis (0.3, 0.5, 0.7, and 0.9 g /kg). The obtained results of the experiment showed that chicks fed with 0.9 and 0.7g/kg of feed Spirulina platensis had significant better valus of LBW, BWG, GR, PI, immune organs, improved FCR, blood parameters, and microbial load. Moreover, chicks fed with 0.7g/kg of Spirulina platensis had the best economic efficiency.
Generally, it could be concluded that, dietary with 0.7and 0.9 g/kg of feed Spirulina platensis could improve the growth performance, blood parameters, biochemical changes in serum and microbial load. From an economical point of view, supplementation of 0.7g/kg of Spirulina platensis is recommended of cobb chicks.

The experimental study was carried out to determine the effects of bacteria (B. subtilis or P. acidilactici) alone or combined supplementation in broiler diets on productive performance, bacteria enumeration and some physiological responses. A total number of birds (360 Cobb broiler chickens at seven d of age) were distributed into nine treatments (40 chicks each), each treatment contained four replicates of ten birds as follows: -
1- Chicks were fed the control diet (T1).
2- (T1) + 0.5 g Bacillus subtilis /kg diet.
3- (T1) + 1 g Bacillus subtilis /kg diet.
4- (T1) + 0.5 g Pediococcus acidilactici /kg diet.
5- (T1) + 1 g Pediococcus acidilactici /kg diet.
6- (T1) + 0.5 g Bacillus subtilis+0.5 g Pediococcus acidilactici /kg diet.
7- (T1) + 0.5 g Bacillus subtilis+1 g Pediococcus acidilactici /kg diet.
8- (T1) + 1 g Bacillus subtilis+0.5 g Pediococcus acidilactici /kg diet.
9- (T1) + 1 g Bacillus subtilis+1 g Pediococcus acidilactici /kg diet.
The obtained results of the experiment showed that chicks fed combined supplementation of B.subtilis 1g+ P. acidilactici 0.5g had significantly higher Live body weight, body weight, growth rate, performance index, Immune organs (bursa and thymus) and improved feed conversion ratio, blood parameters, and microbial load.
Generally, it could be concluded that the combination of B.subtilis 1g+ P. acidilactici 0.5g can be used in broiler diets as a growth promoter because this combination improved growth performance, gut health and intestinal microbial balance of broilers.

A trial was carried out to investigate the effect of drinking water supplemented with dry powder Spirulina algae extract (SP) on productive performance and immune response of growing Japanese quail. A total of 480, 1-d-old quail chicks were randomly assigned equally to 4 treatments for 5 wks. The 1st treatment served as a control, fed a basal diet and drinking water with no supplement, while, the 2nd, 3rd and 4th treatments fed the basal diet and drinking water supplemented with SP extract at a rate of 0.5, 1 and 2 g /Liter, respectively. The results indicated that there was significant improvement of SP extract supplementation on the average body weight gain, health, viability with highest decrease in chicks mortality percent of all supplemented groups. Moreover, the lowest feed consumption and feed intake beside the best significant feed conversion ratio, feed efficiency and European Production Efficiency values were observed in all treated groups. Results also revealed significant (P≤0.05) increase in the relative weights of carcass, liver, heart, lymphoid organs, sex organs, proventriculus, ventriculs, and small intestine length. Abdominal fat was significantly decreased following increasing levels of SP. Moreover, the hematological responses and serum antibody production against Newcastle virus, plasma total protein profile, total antioxidant capacity and Thyroxin (T<sub>4</sub>) concentration were significantly (P≤0.05) increased in all treated groups. However, plasma cholesterol and total lipids had marked lower levels in all supplemented groups. Plasma ALP, ALT and AST activities are fell within the normal range among groups. Therefore, supplementing SP algae extract may possibly maximize the physiological, productive performance and immune response of growing quail chicks.

The current study aimed to investigate the effect of bee pollen (BP) supplementation of Sinai chicken hen diets on the egg production, egg quality traits, some hematological parameters. A total of 120 Sinai hens, 26 weeks old were randomly divided into 4 equal experimental groups (30 hens with 3 replicates, 10 hens each). In the 1<sup>st</sup> group (control), hens were fed on a basal diet without any treatment, while those in the 2<sup>nd</sup>, 3<sup>rd</sup> and 4<sup>th</sup> groups were fed on the same basal diet and supplemented with bee pollen (BP) at 500, 1000 and 1500 mg/kg diet throughout 12 successive weeks.<br /> <br /> The obtained results indicated that:<br /> The live body weight and total weight gain in the 3<sup>rd</sup> group (1000 mg bee pollen/ kg diet) was significantly (P≤0.05) improved as compared with the other groups. The means of laying rate and egg mass in 2<sup>nd</sup> group were significantly (P≤0.05) improved than that of the control group. The highest mean of feed consumption (FC) was recorded in the 2<sup>nd</sup> group, while the lowest one was obtained in the 4<sup>th</sup> group with significant differences. The feed conversation ratio for hens in the 3<sup>rd</sup> group was significantly decreased compared with those of control, 2<sup>nd</sup> and 4<sup>th</sup> groups. Egg weight, exterior and interior egg quality were not affected by BP supplementation.<br /> The means of red blood cells (RBCs) and white blood cells (WBCs) were significantly increased in the treated groups, while the H/L ratio was significantly decreased as compared with control. Serum total cholesterol and triglycerides values were significantly (P≤0.05) decreased, while serum total protein, albumin, and globulin were not affected in the treated groups compared with those in the control group. From these findings could be concluded that, the supplementation of bee pollen at 500mg/kg of Sinai hen diets improved the production performance, some hematological and parameters during egg production period. It is worth to mention that the treating Sinai chicken hens with 500 mg BP/kg diet is more economical and cheaper compared with 1000 and 1500mg BP/kg diet.

This study aimed to investigate the effect ofin-ovo injection with probiotic on hatchability traits, growth and physiological response of post-hatch Sinai chicks. A total of 600 fertile eggs at the initial of the 18<sup>th</sup> day of incubation were used and divided into 4 equal treatments (150 eggs per each). The experimental groups of eggs were arranged as follows, the first group as a control negative (un-treated), the second group as a control positive (injected in air sac with 0.3 ml/egg of sterile distilled water), the third and fourth groups injected with 0.3 ml/egg solution of sterile distilled water contained 1.0 and 2.0 g probiotic per one liter, respectively. Hatched chicks were reared up to 12 wks of age, then growth and some physiological parameters were estimated through the experimental period. Results indicated that in- ovo injection eggs by probiotic with 1.0 or 2.0 g / L result in improve hatchabilityand decrease embryonic mortality percentages. Both body weight gain and feed conversion ratio were significantly improved as a result of in-ovo injection with 1.0 g probiotic/L than the negative control during the overall experimental period after hatch (0-12wks of age). Relative weights of some giblets and organs were increased as a result of in-ovo injection with probiotic as compared with negative control with or without significant effect. Growth and physiological response of hatched Sinai chicks. Therefore, in-ovo injection by probiotic with 1.0 or 2.0 g / liter at 18<sup>th</sup> day of incubation period could be used to improve hatching and subsequent growth performance of hatched Sinai chickens.

An eight-week experiment was conducted to assess the effect of supplementing layer diets with various concentrations of chamomile (CH), turmeric (TR) and their combination (CH + TR) on the productive performance, egg quality traits and yolk chemical composition of laying hens. Total of 144 White Lohmann LSL layer hens, 43 weeks of age, were assigned to six treatments (6 replicates each x 4 birds). Treatments were control (no additives), 1.5 or 3.0 g CH/kg diet, 1.5 or 3.0 g TR /kg diet and 1.5 g CH + 1.5 g TR /kg diet. Egg weight, mass, production and feed conversion ratio were significantly improved by treatments. Chamomile 1.5 g or CH + TR resulted in the highest egg production, egg mass and the best feed conversion ratio. Egg weight was increased by TR or CH + TR inclusion. The treatments had no significant effect on feed intake. The effect of CH, TR and CH + TR on egg quality traits was inconsistent except for yolk color which was significantly improved by the treatments and was more pronounced by TR and CH + TR in comparison with the control. Treatments had no significant effect on the egg surface area, shell traits and albumen weight. Chamomile (1.5 g) improved shape index in comparison with the rest of the treatments except for CH + TR which significantly recorded the lowest index. Herbs supplementation negatively affected the yolk index. There was no significant effect on chemical composition of egg yolk, except for dry matter percentage which was significantly decreased by CH + TR combination. It can be concluded that chamomile, turmeric or their combination as feed supplementation to layer diets had favourable effects on the productive performance and yolk color; however, the effect on egg quality was inconsistent.

A 49 days experiment was conducted to evaluate the effects of different levels of rosemary leaves (RML) or black seeds (BS) powder, as natural feed additives, on growth performance, carcass traits and some blood plasma constitutes of broiler chicks. A total of 210 one-day-old unsexed Hubbard chicks were divided into seven treatments of three replicates of ten chicks each. Treatments were 0.25, 0.50, 0.75 and 1.0% (RML), 0.50 and 1.0% (BS) and no additives (control). Supplementation of RML (up to 0.5%) and BS (up to 1.0%) increased birds body weight (BW) at all ages; the highest final BW was obtained by 0.5% RML and 1.0% BS in comparison with the rest of the treatments. A reduction in BW was noticed with increasing RML levels over 0.5%. All various contrasts of treatments vs. control did not show any significance in average daily gain or feed intake. Significant feed, crude protein and caloric conversion ratios were obtained by 0.5% RML vs. control during the total period. Most dietary RML or BS levels versus control significantly improved the livability and the European production efficiency factor. No significant effects on most carcass traits, plasma total protein and total lipids were detected. Plasma total cholesterol was decreased by 0.75 RML and 1.0% BS compared to 0.25% RML. A significant reduction in plasma triglycerides by 1.0% RML vs. control was reported. All treatments (except 1.0% RML and 0.5% BS) significantly increased plasma uric acids. A significant increment in percentages of bursa by RML (0.25 and 1.0%) vs. control and in spleen by RML (0.75 and 1.0%) was noticed. Supplementation of 0.5% RML and 1.0% BS significantly reduced abdominal fat percentage compared with the control. It was concluded that 0.5% RML and 1.0% BS, as natural feed additives, enhanced broilers performance.

One hundred and twenty, 10-wk-old Gimmizah chickens, as a local balady strain were used in the current study to evaluate the physiological response to zinc (Zn) and/ or creatine monohydrate (CMH) supplementation in drinking water. All birds were weighed and randomly divided into four equal treatments. The first treatment fed the basal diet and served as control, while the second, third and fourth groups were given the basal diet and drinking water were supplemented with, 0.6 mg zinc sulphate/ml, 0.45 mg CMH /ml and 0.6 mg zinc sulphate /ml + 0.45 mg CMH /ml, respectively.
Body weight gain, feed consumption, feed conversion, and relative weight of carcass, abdominal fat, and sex organs were calculated. Serum concentrations of total proteins, total lipids, triglycerides, total cholesterol, alkaline phosphates, thyroxin, testosterone andestradiol (E2) hormones were measured.
The results indicated that the body weight gain, feed efficiency, and relative weight of carcass, abdominal fat, and sex organs were significantly (P≤0.05) increased in the fourth group as compared with the other treatments or the control groups. Moreover, plasma concentrations of total protein, total lipids, triglyceride, cholesterol, estradiol-17ß, testosterone, and thyroxin hormone levels in all supplemented groups were significantly (P≤0.05) higher than the control group. The highest values observed in the fourth group. Therefore, it could be recommended that supplementation of Zn + CMH might be involved in improving the physiological and productive performance of Gimmizah birds.

Two experiments were done to investigate in-ovo feeding of glucose (Exp. 1) for enhancing hatchability and hatching weight by using 300 fertile eggs of Fayoumi breeder. Eggs divided into 5 groups in 60 eggs/ treatment (20/ replicate). At 18<sup>th</sup> day of incubation, eggs injected in the air sac as following groups: first (control) without injection, second was punched (dry punch), third was injected by 0.1 ml distillated water (sham group), fourth and fifth were injected by 0.1 ml glucose at concentrationsof 2.5% and 5%, respectively. Results indicate that hatchability and hatching weight of fourth group recorded significant improvement by 14.71% and 5.68%, respectively compared with control.
In the second experiment, a total number of 120-unsexed Fayoumi chicks, a day old, were arranged to 4treatments in 3 replicates (10 chicks each) as follows: the first group (control) was fed basal diet. The rest 3 groups were chosen from the former experiment, control without injection, groups injected with 0.1 ml glucose either at 2.5% and 5% concentration. All these 3 groups fed the basal diet incorporated with 5% glucose syrup from 1-28 days of age then switched to the control diet up to 56 days of age. Results show that the improvement in hatching weight was continued during starting and growing periods, also feed conversion ratio was enhanced by 10.23% for the group injected with 0.1 ml glucose 2.5% and fed diet contained glucose syrup compared to control. Carcass characteristics were not affected by any of the studied treatment except carcass % which significantly increased in chicks fed glucose syrup and injected with 0.1 ml glucose 2.5%.
Conclusion: in-ovo feeding with glucose 2.5% improve hatchability and hatching weight of Fayoumi chicks. Moreover, incorporating hatched chicks with glucose syrup enhance performance without negative effect on blood glucose and lipid profile.

The present study was conducted to evaluate the effects of propolis, bee-pollen and bee-venom as eco-friendly alternative on productive and physiological performance of broiler chickens. A total of 408 unsexed one week old, Cobb 500 broilers were randomly divided into 8 experimental treatments (3 replicate, 17 chicks each). The first treatment was fed basal diet without any additives and served as a control. The second treatment was fed the basal diet supplemented with the growth promoter Biox-Y<sup>®</sup> 0.5g per kg of diet. The third and the forth treatments were fed basal diet supplemented with propolis (200 or 400 mg/kg diet). The fifth and the sixth treatments were fed basal diet supplemented with bee-pollen (1 or 2 g/kg diet). The seventh and the eighth treatments were fed the basal diet and their water was supplemented with bee-venom (1or 2 mg/L water). Weekly body weight, body weight gain, feed intake and feed conversion ratio obtained. Blood samples were obtained at the end of the experiment (7 weeks of age) to determine blood parameters. The obtained results showed that the chicks fed diet with propolis (400 mg/kg diet) had significantly higher body weight and total body weight gain compared to the control treatment. Also, all treated treatments had significantly lower average daily feed intake during the whole experimental interval and significantly improved total feed conversion ratio compared to the control and Biox-Y<sup>®</sup> treatments. The chicks fed diets containing propolis (200 or 400 mg/kg diet) or bee-venom (2 mg/L water) or bee-pollen (2 g/kg diet) showed significantly lower plasma cholesterol and LDL-cholesterol concentration compared to the control and Biox-Y<sup>®</sup> treatments. Consequently, propolis (200 or 400 mg/kg diet) treatments and bee-pollen (2 g/kg diet) treatment had significantly higher plasma HDL cholesterol concentration than the control treatment. Broilers fed propolis (200 or 400 mg/kg diet) for 6 weeks had significantly lower serum AST and ALT concentrations compared to the control treatment. The chicks fed diet with propolis (400 mg/kg diet) showed significantly higher plasma T3, T4 concentration or T3/T4 ratio compared to the control treatment.

The present study was conducted to evaluate the effects of propolis, bee-pollen and bee-venom on meat quality and immune response of broiler chickens. A total of 408, one week old, Cobb 500 broilers were randomly divided into 8 experimental groups (3 replicate, 17 chicks each). The first treatment was fed basal diet without any additives and served as a control. The second treatment was fed the basal diet supplemented with the growth promoter Biox-Y<sup>®</sup> 0.5g per kg of diet. The third and the fourth treatments were fed basal diet supplemented with propolis (200 or 400 mg/kg diet). The fifth and the sixth treatments were fed basal diet supplemented with bee-pollen (1 or 2 g/kg diet). The seventh and the eighth treatments were fed basal diet and its water was supplemented with bee-venom (1or 2 mg/L water). Blood samples were obtained at the end of experiment to determine blood parameters. The obtained results showed that broiler chicks fed diet supplemented with propolis (400 mg/kg diet) or bee-pollen (2 g/kg diet) had significantly higher breast muscles protein, moisture concentration and bone strength compared to the control and Biox-Y<sup>®</sup> treatments. Chicks fed diets with propolis (200 mg/kg diet) or drinking water with bee-venom (1 or 2 mg/L) resulted in significantly higher Haemoglobin and Hematocrit concentration compared to the control treatment. Humoral immune response against sheep red blood cells was increased in propolis (400 mg/kg diet) or bee-venom (2 mg/L water) treatments compared to the control treatment. While, cell mediated immune response (PHA-L injection) was increased significantly in propolis (400 mg/kg diet) treatment than the control or Biox-Y<sup>®</sup> treatments. The chicks fed diet with bee-pollen (1 or 2 g/kg diet) or Biox-Y<sup>®</sup> (0.5 g/kg diet) had significantly higher relative thymus weight. Also, bee-venom (2 mg/L water) treatment had significantly higher relative spleen and bursa weights compared to the control treatment.

The study was conducted in two governorates Al-Sharkia and El-Fayoum, to investigate the impact of management interventions packages on poultry productivity under family chicken production system in Egyptian rural. The management intervention packages included housing, vaccination, chick rearing, improved strains and feed supplementation. All data collected during the period from January to December 2015. The target population was smallholder keeps indigenous chicken and management interventions had been disseminated by extension services. Samples of two hundred individual householders' were randomly chosen, through semi-structured interviews with questionnaires to collect data through monthly visits. The results indicate that 45% of the smallholders adopted the management interventions package as disseminated. Majority (50%) selective components of the management interventions package were considered full packages; feed supplementation and improved strains; feed supplementation and vaccination. The highest average in flock size was observed at full package adopters (96.47 birds) followed by feed supplementation and improved strains adopters packages (73.22 birds) and feed supplementation and vaccination adopters (45.76 birds). There were highly significant differences between management intervention packages in hen's and cocks sexual maturity age, hen's age at the end of egg production period age. The highly average of egg number/hen/year was reported for chicken raised under full packages group (183.26 eggs) with highly average weight of 44.26 gm during the shortest period of 46.40 weeks. However, the lowest average of egg number/hen/year was produced by chicken raised under non-adoption packages group (86.50 eggs) with lowest average weight of 28.60 gm during longest period of 94.00 weeks. Therefore, it could be recommended that the government and development partners should design a management intervention adoption program based on the demographic and socio-economic conditions of smallholder farmers to increase indigenous chicken productivity.

The study was conducted in Al-Sharkia and El-Fayoum governorates, Egypt. This study aimed to determine the socio-economic factors that influencing on chicken smallholder's adoption behavior of management intervention packages in Egyptian rural sector. Samples of two hundred individual households' were randomly selected, through semi-structured interviews with questionnaires to collect data through monthly visits from January to December 2015. The results indicated that adoption of the management intervention package was influenced by gender, smallholder’s experience, smallholder’s education level, group membership, distance to the market, access to extension and training programs, veterinary services and marketing information. Smallholders with a lower education level were likely to adopt housing, chick rearing, improved strains and feed supplementation; and improved strains packages, whereas, smallholders with a higher education level increased the likelihood of adopting the full package. Males were more likely to adopt the full package, while females more likely to adopt components of management intervention packages. Smallholder experience in raise indigenous chicken had a positive significant and marginal effect on adoption of the full package. Access to training and extension services increased the probability of adopting disseminated packages, the ability to selective from the packages and the adoption of full packages. A decrease in distance to the market increased the probability of adopting the full package, but reduces the probability of adopting feed supplementation and vaccination. It could be recommended that, it should to encourage the chicken smallholders, in Egyptian rural sector, to work in self-help groups and create awareness through training. Micro-credit providers should provide credit in order to encourage adoption of the management intervention package.

The high ambient temperature during summer causes various negative effects compromising laying hen performance. The present study aimed at studying the possible effects of yeast culture and/or vitamin C dietary supplementations to laying hens on alleviating the negative effects imposed by high ambient temperature during summer. A total of 200 Hy-Line Brown hens 32 weeks old, were randomly allocated to four groups with 50 hens divided at five replicate each. The first group received basal diet without any supplementation and served as control group (C). The groups 2, 3, and 4 received basal diet supplemented with 0.2% dried yeast (Yeast), 250 mg of vitamin C (Vit-C ), and 0.1 % dried yeast + 125 mg vitamin C (Yeast+Vit-C) respectively. Hens were raised in wired cages in an open house. The experiment was carried out during summer, and the averages ambient temperature and relative humidity were 30.9±1.3 ͦC and 48.8±0.1%, respectively. Feed intake, feed conversion, egg production were recorded and egg quality parameters were measured. Yolk cholesterol, total lipid and plasma biochemical contents were determined. Antibody titer of Newcastle (NDV), Infectious Bronchitis (IBDV) and Avian Influenza (AIDV) disease virus were quantified after 30 days of immunization. Ileum Salmonella, E-coli and total bacterial count (TBC) were also quantified. Yeast supplementation with or without vitamin C showed a positive effect on feed intake, feed conversion, egg production and egg quality. Improvement in both external and internal egg quality parameters were observed for dietary supplemented groups compared to the control group. Yolk cholesterol and total lipid decreased significantly with all supplementations. The antibody titer for the immunized viral diseases NDV, IBDV and AIDV significantly increased with yeast supplementation. Ileum E-coli and TBC were significantly decreased by yeast supplementation. It can be concluded that yeast culture is a powerful dietary supplement during hot season, since they can alleviate the negative effects of heat stress on laying hen performance and egg quality. Also, they can be used as an immunomodulation of pathogen challenged animals or pre-immunization. Moreover, vitamin C can also be used as anti-stress but with less pronounce positive effect.

The aim of this study was to evaluate the effects of bird density and the consequences of adding dietary vitamin E on broiler performance, blood metabolites, gastric bacterial enumeration, bone contents and the humeral immunity. A total number of 180 one day-old Arbor Acres broiler chickens were randomly divided into 4 equal groups. Each group was subdivided into 3 replicates containing 15 chicks each. The first group was housed at density of 10 birds/m<sup>2</sup> and served as the positive control. The second group was housed at density of 12 birds/m<sup>2</sup>and served as the negative control. The first and second groups were fed the basal diet. The third and fourth groups were housed at density of 12 birds/m<sup>2</sup>, and were fed the basal diet supplemented with vitamin E at either 100mg/kg diet (third group) or 200mg/kg diet (fourth group). The results indicated that birds kept under high stocking density showed reduction of growth performance, plasma metabolites and immune response of broilers. While, the immune response of broilers was improved by dietary vitamin E supplementation under the intensive density. In ileum and ceca, the bacterial count was improved when all pathogens counts (E.coli, Salmonella and Clostridium) were decreased in birds reared at density of 12 birds/m<sup>2</sup> but fed diets supplemented with vitamin E even 100 and 200 mg/kg. It can be concluded that, under high stoking density condition, vitamin E supplementation can improve the production performance and the immune response of broiler chickens.<br /> <br /> <strong> </strong>

This study evaluated the impact of supplementing diets of Sinai cockers with bee pollen on the productive performance, some hematological parameters and semen physical characteristics. Sixty Sinai cockers (4 groups × 3 replicates × 5 cockers), 28 weeks old, were equally classified into four groups. In the first group (control), cockers were fed on the commercial ration, while those in the 2<sup>nd</sup>, 3<sup>rd</sup> and 4<sup>th</sup> groups were fed on the same diet and supplemented with 500, 1000 and 1500mg bee pollen/kg diet, respectively. The achieved findings showed that the final body weight (FBW) and total weight gain (TWG) in the treated groups were significantly (P≤0.01) increased, while the total feed intake (TFI) was insignificantly affected as compared with control. The red blood cell and white blood cell counts as well as hemoglobin level for treated cockers were significantly (P≤0.01) increased, while the heterophils/lymphocytes ratio was significantly decreased compared with control group. The means of blood proteins for treated cockers were insignificantly differed, while the cholesterol and triglycerides concentrations were significantly (P≤0.05) decreased as compared with cockers in control group.The means of ejaculate volume and the percentages of advanced motility and live sperms, as well as the concentrations per ml and per ejaculate of cockers in the treated groups increased significantly (P≤0.01) compared with control group. Also,the percentages of dead sperms and sperm abnormalities for treated cockers were significantly (P≤0.01) decreased compared with control.
From the obtained results, could be concluded that, the supplementation of the diet with bee pollen at different levels improved the total weight gain and semen physical properties compared with control. Thus, from these results could be recommended to use BP in Sinai chicken diets at 1000mg/kg diet to improve the ejaculate volume, advanced motility, live sperms, concentrate per ejaculate, which amounted 34.13, 26.32, 7.17, 43.62%, respectively, while the sperm abnormalities was significantly decreased by about 36.28% compared with control group.

The present study was designed to study the direct influence of supplementing of layers diet at late phase of egg production and housed in cages with high levels of vitamin K<sub>3</sub> on productive performance, eggshell parameters, tibia bone composition and histological observation, hatching traits and some blood parameters. One hundred and fifty Mandarah chicken females with thirty males were individually housed in cages from 55 up to 67 weeks of age. The birds were randomly divided into 5 groups representing the dietary supplementation. The birds of the first group was served as control (T1) without any supplementation and fed diet contains 3 mg menadion (K<sub>3</sub>) / kg diet . The rest 4 groups were supplemented with menadion as additional doses of vitamin K<sub>3 </sub>source to be 7, 11,15 and 19mg menadion / kg diet for T2, T3, T4 and T5 groups respectively. Obtained results revealed that hens of T3, T4 and T5 groups represented significantly (P≤ 0.05) produced larger eggs , besides all supplemented groups represented highest (P≤ 0.05) egg mass and egg production% compared to those for control group (T1).Also, highest values of shell thickness (mm) and Ca% in eggshell were detected for eggs of T<sub>3 </sub>and T<sub>4</sub> groups compared to the rest groups. Moreover, the best improvement of tibia measurements (length , width and breaking strength) and composition (weight, ash%,Ca% and P%) were recorded for hens T3 and T4 groups. Eggs produced from all supplemented groups represented significant increase of fertility and hatchability of fertile egg percentages compared to those for control one. Birds of the T3 groups recorded the highest values of the serum osteocalcin and plasma Ca, ICa, P and alkaline phosphatase. Histological observations of tibia bone for birds of T3, T4 and T5 groups illustrate the increase of medullary bone, thick outer cortical layer and osteoblasts cell activity. In conclusion, supplementing the layer diet at late phase of production and housed in cages with either 11 or 15 mg vitamin K<sub>3</sub> / kg diet could be a promising tool for realizing the best improvement of egg production, shell and bone quality and hatchability%.

The present experiment was conducted to study the effect of dietary supplementation with carotenoids- enriched Spirulina platensis algae (SA), flock age on egg weight loss% ,embryonic weight and mortalities %, hatching traits and blood constituent of Bandarah chicks. One hundred and thirty five females with fifteen males from Bandarah chicken strain at 30-week of age (YA) besides the same numbers at 56-week of age (OA) were housed in floor pens. Five experimental bird groups for each age were fed as follows : basal diet without supplementation of SA (T1) , basal diets supplemented with 40 mg (T2), 80 mg (T3), 120 mg (T4) , 160 mg (T5) SA / Kg diet. The obtained results showed that eggs of elder flock significantly lost greater percentage of weight compared to the younger one. Elder flock age had greater (p≤0.05) embryonic mortality percentage compared with those for younger one and supplementation the diet with SA reduced embryonic mortality. Supplementation the diets with 40 mg for younger flock or 160 mg SA/Kg diet for elder flock , represented significant improvement of macroscopic fertility, hatchability of fertile eggs and hatched chick body weight. Lowest concentrations(p≤0.05) of -carotene and Zeaxanthin were detected in the liver of control chicks compared to those for all other groups. The elder flock represented significantly higher Zeaxanthin carotenoid concentration in the chick liver compared to those for younger one. Irrespective to flock age, baby chicks of T2 and T5 groups represented the highest significant values of total antioxidants and lowest LDL compared with the others. Regarding flock age, chicks produced from elder flock had higher significant values of cholesterol, LDL and malondialdhide, while chicks produced from younger one had higher values (p≤0.05) of total antioxidants and HDL. In conclusion, supplementing the diet of parental younger flock age with 40 mg SA/Kg diet and 160 mg SA/Kg diet for the elder one could be a good tool for realizing the best improvement results of fertility, hatchability and hatched chick body weight, besides highest concentration of total antioxidants in the blood of hatched chicks.

The present study was carried out to investigate the effect of dietary ginseng (Gn) and ginsenosides (GnD) supplementation on productive, physiological and immunological parameters of Gimmizah cockerels. A total number of 140 chicks of Gimmizah native breed were individually weighted and randomly divided into 7 equal treatmental groups with 5 replicates (4 chicks per each cage) from 4 -16 wks of age. The first group fed the basal diet without any supplementation and served as a control. The other six treatments were fed the basal diet supplemented with 100, 200 and 300 mg of ginseng or ginsenosides / kg diet, respectively. All birds received feed and water ad-libitum throughout the experimental period.<br />At the end of the experimental period the treated groups recorded significant highest BWG. The best FCR was recorded for groups supplied with 300 mg Gn/kg diet then 200 mg GnD/kg diet compared with control group. Activity of ALT enzyme and lipid profile were significantly improved by supplementation different levels of Gn and GnD compared with control group. Supplementation basal diet with different levels of Gn and GnD significantly improved all immunity statues of the bared (Lysozyme and Bactericidal activity and the IgM, IgG, interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) concentrations). The intestinal total aerobic, total coliform and anaerobic counts had been decreased with supplementation of basal diet with Gn and GnD at different levels compared with the control group. The psychrophilic and coliform bacteria counts, in stored breast and thigh meats, had been significantly decreased for groups fed basal diet supplied with Gn or GnD at level 300 mg/kg diet compared to other experimental treatments. The optical density values of meat muscles recorded for groups supplied with 300 mg Gn or GnD/kg diet were greater than which measuring in control group and the other experimental groups. In conclusion, supplementation cockerel's diet with 300 mg ginseng /kg improved the productive performance, immunological capacity and meat quality of Gimmizah cockerels during the growing period.

This study was carried out to investigate the relationship among egg weight and their components in four genetic lines of Kurdish local chicken. 299 eggs were collected from four genetic lines of Kurdish local chicken. After collection, egg weight, yolk weight, albumin weight and shell weight were weighted to nearest (0.01g). The Two principal components (PC1 and PC2) were extracted in Black, Black with brown neck, White shank feather and white non-feathering shank, which explained (82.71, 80.45, 84.09, and 76.40) respectively, of total variation. Significant differences were observed between the four genetic lines (Black, Black with brown neck, white with shank feather, and white non-feathering shank). We found that egg weight highly (P<0.001) correlated with yolk (r<sup>2</sup>= 0.900, 0.822, 0.898, 0.690) respectively, albumin weight (r<sup>2</sup>= 0.498, 0.575, 0.524, 0.845) and shell weight (r<sup>2</sup>= 0.525, 0.549, 0.649, 0.339). It was concluded that egg weight and their component significantly differences among the groups due to the differences in genotypes. These finds could be used to improve egg quality and for selection criteria.

The aim of this work was to study the efficacy of antibiotic growth promoter alternatives supplementation in the corn soybean meal diets on growth performance, carcass cuts and lymphoid organs %, some plasma parameters and some economic traits of broiler chicks. 150 one-day-old chicks (Arbor Acers), un-sexed were randomly divided into five experimental treatments with tree replicates per treatment group. The control group (T1) was fed basal (starter and grower) diets without supplementation, while other groups T2: T5 were fed basal diets supplemented with colistin antibiotic 1 g/ kg (Colistix®), Guanidinoacetic acid 0.6 g/ kg (Cre-Amino®), Lactobacillus acidophilus 1 g/ kg (Bio-Bac-Lac®) and Beta Mannanase 0.3 g/ kg (Hemicell®). At 32 days results revealed that, live body weight and daily weight gain for the broiler chicks fed T1, T2 and T3 diets were higher than those fed other dietary treatments. Chicks fed T2 and T3 diets had significant better feed conversion ratio compared with those fed T4 or T5 diets. The best protein (PCR), energy (ECR) conversion ratio and the highest performance index (PI) and production efficiency factor (PEF) were recorded for T1-T3 compared with other dietary treatments (T4: T5). Plasma cholesterol, HDL, LDL and GOT were not significantly different than control, while total lipids, triglycerides or GPT were significant. Difference in carcass cuts were not affected by treatments except breast % was significantly decreased than control. Chickens fed T3 diets showed the highest significant thymus ad bursa % compared with other dietary treatments. The results of economic traits showed that chickens fed basal diets supplemented with 0.6% guanidine acetic acid support and enhance economic efficiency without adverse effect on growth performance of broiler until 32 days of age. Therefore, it could be recommended from this study to
