Comparison study was carried out among three genotypes of Baheij breed, Baheij selected breed for increasing body weight at 8 weeks of age, Baheij upgraded groups through three generations and control group. Results were as follows:1- Chicks of the 3rd generation were the heaviest (p<0.001) compared to those of the 1st and 2nd one at the different studied ages. Also, means of body weight of the upgraded group was the highest (p<0.001) compared to the other two groups and the selected group surpassed (p<0.001) the control one at all ages studied.2- The three studied factors affected significantly growth rate percentage (GR %) where birds of the 3rd generation had the highest value of GR% through most of the studied intervals. The upgraded group had the highest mean at 12-16 wks of age where, the selected group grew faster at 8-12 wks of age. Both of the upgraded and the selected groups had significantly the highest values compared with the control one at 0-12, 12-20 and at 0-16 wks of age, while both of the upgraded and control groups surpassed (p<0.001) the selected one at 12-16 wks of age.3- Body weight (BW), shank length (SL), keel length )KL) and breast width had significantly (p<0.01) higher averages at 12 wks. of age compared to those at 8 wks of age. Also, the selected group had significantly the highest BW while, the upgraded group had the highest average of SL. Moreover, males were heavier (p<0.01) than females. 4- The birds of the 2nd generation had the best (p<0.01) chick viability at 0-4 wks of age, while the values of both of the 1st and 3rd generations were nearly similar and higher than that of the 2nd one at 4-8 wks of age. 5- Live body weight, carcass, gizzard, and heart weights differed (p<0.01) in birds of the 3rd generation compared to that of the 2nd one at 16 and 20 wks of age. On the other hand, upgraded group had the highest (p<0.01) values of most of carcass studied traits compared to the others, while the control one had significantly (p<0.01) the heaviest liver. It could be concluded that upgrading through crossing Silver Montazah sires to Baheij strain dams surpassed the selection in Baheij strain at 8 weeks of age throughout three generations in improving growth traits, chick viability, and carcass traits of progeny of both F2 and F3.

M.A.
El-Sayed
Chromosome homology is highly conserved between chicken (Gallus gallus) and Japanese quail (Coturnix japonica) and a few chromosome rearrangements occurred in the evolution of these two species. Blood samples were collected from chicken strains (21 Silver Montazah and 20 Mandara) and Japanese quail lines (22 Beige and 21 sample Grey). Eight chicken and six quail microsatellite markers were used reciprocally. Highly polymorphic microsatellite markers 12 out of 14 with ratio of 85.7% were successfully worked reciprocally and achieved PCR product in both species. The successful cross-species amplification led to identification of polymorphic markers that will be indispensable for identifying homologous regions on chromosomes. The majority of the loci were highly polymorphic information content (PIC) indicated that the most (12/14) of the selected microsatellite sequences could be serve the genetic diversity on different levels including conservation of such genetic resources, future improvements for these two poultry species and/or understanding different genome arrangement and knowledge interests.

This work was carried out to study the effect of dietary Zinc methionine supplementation on some productive, reproductive and physiological performance traits of aged male and female Inshas strain laying hens. A total number of 150 laying hen plus 15 cockerels of Inshas strain at 48 weeks of age were used in this experiment up to 60 weeks of age. All birds were randomly divided into five equal groups each of 30 females and 3 males, with three equal replicates, wing banded and individually weighed, with nearly similar average initial live body weight of all groups. The 1st group (T1) was fed the basal diet contained 50 mg Zinc oxide/kg diet according to NRC, (1994), and served as control, while 2nd, 3rd, 4th and 5th groups (T2, T3, T4 and T5 respectively) were fed the basal diet supplemented with 40, 60, 80 and 100 mg Zinc methionine/kg diet ,respectively. Final body weight, body weight gain, egg production percentage, shell thickness and shell weight percentage were significantly (P≤0.05) improved for birds fed diet supplemented with Zinc methionine at levels 60, 80 and 100mg/kg diet and albumen weight percentage at levels 40, 60, 80 and 100mg/kg diet compared to those fed the control diet. Gradual increase had been observed in plasma hemoglobin (Hb), red blood cells (RBCs), hematocrit,white blood cells (WBCs), lymphocyte percentage, testosterone, estrogen,progesterone and Zinc (Zn) concentrations and gradual decrease in plasma heterophill/lymphocyte ratio, phosphorus (P), Copper (Cu) and Iron (Fe) concentrations with increasing dietary levels of Zinc methionine compared to control group. Linear increase was observed in some semen quality traits {ejaculate volume (E.V), sperm concentration (S.C), live sperm percentage (L.S%), sperm motility (S.M), total sperm per ejaculate(TS/E) and total live sperm per ejaculate (TLS/E)},as well some histomorphological parameters of male testicular tissues (Germinal epithelium thickness and seminiferous tubular diameter), relative testes weight, relative oviduct weight, fertility percentage, hatchability percentage of total eggs and hatchability percentage of fertile eggs were linearly increased but, abnormal sperm percentage (Ab.S%) and total abnormal sperm per ejaculate (TAbS/E) were linearly decreased as the levels of Zinc methionine in cocks diet increased compared to cocks of control group. Data from the current study concluded that adding zinc methionine up to 100 mg/kg diet could be used as an efficient tool for improving productive, reproductive and physiological performance of male and female aged Inshas strain laying hens.

GOLDEN SABAHIA … A NEW STRAIN OF CHICKENS
Producing egg-type commercial breeds of chickens locally, must be done. Certain attempts had been made to develop some foundation stocks to be utilized in the process of producing egg-type commercial breeds of chickens. Performance studies for the developed foundation stocks proved that further development could be made in order to utilize the new foundation stocks for the process of producing commercial breeds of chickens. In this study, a new foundation stock was developed for egg production named as Golden Sabahia strain in El Sabahia Poultry Station. Golden Sabahia strain contributes 7/8 (87.5%) blood of Lohman brown (LB) commercial strain and 1/8 (12.5%) blood of four developed strains using systems of breeding coupled with selection. The down color of the Golden Sabahia chicks is yellowish red. Adults' birds of Golden Sabahia are buff in color and each feather is crossed of light bars. This strain has a columbian pattern with a single comb and red ear lobes. The beak is yellowish brown and, the shanks and skin are yellow. The Golden Sabahia strain was found to be superior to the four developed strain with respect to average annuals egg mass production. Averages annuals egg number, egg weight and egg mass were 219 egg, 57.5 g and 12600 g , respectively. This new strain of chickens could be a threshold for producing sire parents of commercial egg type breed of chickens.

EFFECT OF EGGSHELL OSTEOPONTIN PROTEIN ON SKELETAL EMBRYONIC DEVELOPMENT AND HATCHING TRAITS OF DEVELOPED CHICKEN STRAINS
The present study was designed to study the change of shell quality, shell strength, hatching output, calcium (ca) and phosphorus (ph) concentrations in tibia bone for embryos and hatched chicks, bone strength and some related physiological parameters as affected by either chicken strain (Mandarah, M and Gimmizah, G) or osteopontin (OPN) protein in eggshell. Results indicated that M strain surpassed (p≤0.05) G one for OPN concentration (ng/ μL) in eggshell of fresh eggs, eggshell at hatch, tibia for hatched chicks besides in hatched chick's blood. Egg quality including eggshell weight %,shell index, shell strength (Newton), eggshell and eggshell membranes thickness (mm) were significantly increased for M strain compared with those for G one, whereas egg abnormalities % and egg weights were significantly (p≤0.05) increased for G chickens. Moreover, egg weight loss % during incubation, embryonic mortality %, hatch time (h) and hatch window (h) were significantly diminished for eggs produced from M chickens compared to those for G one besides, M strain had the higher percentage of hatchability of fertile eggs (p≤0.05). Mandarah chickens represented significant increase of ca and ph concentrations compared with G ones in fresh eggs and eggshell for embryos at days 9 and 15. Mandarah chicks surpassed (p≤0.05) G ones with respect to plasma ca, ph and parathyroid hormone. Also, tibia bones for embryos at day 15 and hatched chicks were stronger (p≤0.05) for M strain than those for G one.The important role of the genes due to chicken strain besides OPN protein in eggshell and embryonic bone could open promising tool for understanding the quality of eggshell and its applications for breeding programs.

EFFECT OF MAGNETIZED WELL WATER ON BLOOD COMPONENTS, IMMUNE INDICES AND SEMEN QUALITY OF EGYPTIAN MALE GEESE
The present study was carried out to study the effect of exposing tap water and well water to magnetic fields on blood components, immunity indices and the semen of Egyptian geese. Sixty four one year-old male geese were randomly divided into four equal groups, each made up of four replicates of 4 ganders. The treatments included tap water (TW) as group 1 and well water (WW) as groups 2. The well water was offered with exposure to a magnetic field of 4000 gauss (MWW 4000; group 3) or of 6000 gauss (MWW6000; group 4). During the experiment, the ganders of all groups were kept in an intensive system, with confinement in a house, and fed a commercial mash feed ad libitum. Natural mating was practiced from November 2015 to the end of May 2016. The well water had poor quality. Magnetic treatment improved the quality of the well water, with 6000 gauss having a stronger effect than 4000 gauss. The genders who drank WW showed significantly (p<0.05) poor semen quality, reproductive traits, testosterone hormone besides renal and liver function. Magnetizing the well water improved semen quality, reproductive traits, functions of kidney and liver, antioxidant status and immune response with a more favourable influence of 6000 than 4000 gauss. Thus, magnetizing well water, particularly with 6000 gauss, may offer a possible solution for improving the physiological and immunological traits of geese receiving well water.

THE INFLUENCE OF DIETARY BORON SUPPLEMENTATION ON PERFORMANCE AND SOME PHYSIOLOGICAL PARAMETERS IN BANDARAH CHICKENS 2- LAYING PERIOD
amina
elsaadany
A total of one hundred hens and twenty cocks of Bandarah strain at 28 weeks of age were housed individually in single cages and distributed randomly among four treatment groups (25 hens and 5 cocks/ group) and the experiment ended at 44 wks of age. Birds in group1 were fed a basal diet and served as control group, the other three groups 2, 3 and 4 were fed a basal diet supplemented with 100, 200 and 300 mg boron/kg feed, respectively. Results indicated that supplemental boron to hens’ diet had no significant effect on egg production, egg weight, egg mass, feed consumption and feed conversion compared with control group. Significant increases were observed for egg shell%, shell thickness and Haugh units with increasing the boron level. While shape index, albumen and yolk percentages were not affected by treatments. Supplemental boron significantly increased egg shell calcium, phosphorus and boron concentrations. Moreover, plasma minerals (Ca, P, Fe, Cu and B) were significantly increased with the increase of boron level. Hematological parameters (Hb, PCV, RBCs and WBCs) were improved by addition boron to layer diets. There was a significant increase in plasma total protein, globulin, glucose and serum T3 resulted from dietary boron. Lipid profile and liver function significantly improved for boron treatments. Additionally, semen quality, fertility and hatchability percentages significantly improved with boron at different levels compared with control value. It can be concluded that boron supplementation to layer diets had a positive effect on plasma minerals (Ca, P, Fe, Cu and B) and egg shell (Ca, P and B). However, egg quality, reproductive and physiological status were improved. It is suggested that up to 300 mg boron/kg diet could be used in layer diets without any adverse effect on laying hens performance.

GROWTH PERFORMANCE, REDOX STATUS AND ANTIBODY TITERS AGAINST NEWCASTLE DISEASE VIRUS IN BROILER CHICKENS FED EXCESSIVE DIETARY VITAMIN E UNDER HEAT STRESS CONDITIONS
Ahmed
Abuoghaba
This experiment aimed to study the effect of supplementation excessive level of vitamin E (1000 mg/kg diet) on growth performance of broiler chickens under heat stress conditions. One hundred and fifty Cobb broiler chicks, 14 days old, were divided into three equal groups. Chicks in the 1st group were fed on the commercial basal diet; while those in the 2nd and 3rd groups were fed the same diet with adding 200 and 1000 mg Vit. E/kg diet, respectively. Broilers had free access to feed and fresh tap water. Broilers were raised under 32 and 30°C during the first and second weeks, respectively, while the broilers were reared under natural ambient temperatures from 2-5 weeks of age. The broilers in the different groups were daily exposed to continuous lighting program.The obtained results showed that the broilers in the 2nd group tended to have higher daily weight gain (p=0.056) in addition they significantly improved feed conversion ratio (FCR; p<0.01) compared to the other groups during the period 28-35 days of age. At 35 days of age, broilers in the 2nd group had heavier live body weights (p<0.05) compared to control.Broilers in the 2nd group (200mg/kg diet) significantly enhanced (p<0.05) plasma total antioxidant capacity (p<0.05) compared to the other groups. Plasma malondialdehyde concentrations for broilers in the 2nd and 3rd groups were decreased compared to control group. The higher antibody titers against Newcastle Disease Virus in the serum were observed at 30 days of age in the 200 mg Vit. E/kg group compared to the other treatment groups. H/L ratio, plasma cholesterol, and glucose concentrations were insignificantly differed among treatment groups.In general, it could be concluded that the excessive vitamin E supplementation during summer reduces its effect for maximum performance, while the better antioxidant capacity and higher antibody titers were achieved by adding the lower level (200 mg Vit. E/kg diet).

EFFECT OF DIETARY SUPPLEMENTATION OF GRAPE SEED EXTRACT OR VITAMIN E AS ANTIOXIDANT ON REPRODUCTIVE AND PHYSIOLOGICAL PERFORMANCE DURING SUMMER SEASON 2- AGED MALES DEVELOPED CHICKENS
The objective of this study was evaluatethe effect of dietary grape seed extract (GSE) or vitaminE (VE) supplementation on some reproductive and physiological performance traits of aged males of Dandrawy strain during summer months. A total number of 150 laying hen plus 30 cocks of Dandrawy (DN) strain at 60 weeks of age were used in this experiment up to 72 weeks of age. All birds were randomly divided into five equal groups each of 30 females and 6 males, with six equal replicates, wing banded and individually weighed, with nearly similar average initial live body weight of all groups. The 1st group (T1) was fed the basal diet contained 10 mg V E/kg diet according to NRC, (1994), and served as control, while 2nd, 3rd, 4th and 5th groups (T2,T3,T4 and T5 respectively) were fed the basal diet supplemented with 100,200mg GSE 150 and 200 mg V.E/kg diet, respectively.The obtained results indicated that increasing supplemental (GSE)or(V.E)resulted in an increase insignificantly in final body weight and body weight gain,however they did not affect feed consumption of cocks.All concentrations of dietary (GSE)or(V.E)had significant (p≤0.05) improvements in semen quality. Also, there was significant (p≤0.05) increase of the fertility and hatchability percentages from total eggs and hatchability from fertile eggs. Plasma of Tri Glycerides, Cholesterol, LDL,Glucose, and MDA were decreased (p<0.05) for cocks either supplemented with GSE or Vit. E, while HDL, Total Protein, Albumin, GSHPx and SOD, were increased (p<0.05).There were Significant (p<0.05) differences between treatments for IgG and IgM and the best value was recorded in the group received 200 mg (GSE)/kg diet followed by the group received 200mg (Vit.E). The (GSE) or (Vit.E) supplementation at 200 mg/kg diet had significantly greater testosterone, T3 and T4 concentrations (p<0.05) in blood serum than the other groups. It could be recommended that supplementing the Dandrawy cocks diet with 200, mg/kg diet (GSE)or (Vit.E) may alleviated the negative effect of hot temperature during summer season and may improved most of the previous mentioned reproductive traits, semen quality, fertility and hatchability and blood parameters.

El-Faham
A total sum of 180 Hubbard broilers chicks (46.9 ± 2.5 g) at one-day-old were used, weighed and divided into six treatments of three replicates each to investigate effects of using two levels of amino acid threonine (T) being (0.0 or 1.0 g/ kg diet) and three different methionine sources: DL- methionine (DLM), acid liquid methionine (ALM) or methionine hydroxy-analogue-calcium salt (MHA) in 2 x 3 factorial design on carcass tissue weight distribution and chemical composition for both male and female broiler chicks, fed corn-soybean meal based diets. Results obtained declared that skin and subcutaneous fat percentages of carcass parts were not altered by neither different dietary treatments nor bird sex. Also, distribution of both muscles and bones was not altered by different dietary treatments as male and female chicks appeared similar, except for muscles percentages of breast and drumstick where, males recoded significantly higher values than female chickens. Additionally, all parameters of tibia bone measurements (tibia length, tibia width, tibia Seedor index (SI) and tibia Robusticity index (RI)) were not significantly affected by different dietary treatments, while male chickens had a significant higher figures (tibia length, width, (SI) and dry tibia weight percentage (DTW %)) than female chickens. Data of chemical composition of both tibia bone and breast meat were presented insignificant effect of either different dietary treatments, or bird sex. While most of studied parameters showed insignificant response due to interactions between threonine levels (T), methionine sources (M) and sex of birds (S). According to results obtained, it would be stated that interactions between dietary threonine (T) supplementation, methionine (M) sources and sex (S), for nearly all studied parameters, were insignificant.

amina
elsaadany
The present experiment was carried out for studying the effect of supplementing diet with propolis on Bandarah chicks’ performance. Atotal of 360 unsexed one-day old chicks of Bandarah strain were randomly distributed into four treatments groups of three replicates (each contained 30 chicks). Chicks were raised in battery brooder throughout the experimental period which ended at 12 wks of age. Group one was fed a basal diet and considered as control group. The other three groups 2, 3 and 4 were fed a basal diet supplemented with 150, 300 and 450 mg propolis/kg diet, respectively. The results showed that body weight (BW) and body weight gain (BWG) were significantly (p<0.01) increased with increasing of propolis level. Average of feed consumption was not affected by adding propolis during the first periods of experiment (0-4), (4-8) and the overall mean (0-12) wks. However, during (8-12) wks of age feed consumption was significantly decreased with increasing of propolis levels. The best feed conversion ratio was recorded for the group supplied with the highest level of propolis (450 mg/kg diet). Carcass relative weight and the lymphoid organs weights (spleen, bursa and thymus) were significantly improved (p<0.01) by increasing propolis supplementation. Chicks fed diet supplemented with propolis were significantly increased hematological parameters (Hb, PCV, RBCs and WBCs). Likewise, plasma protein, albumin, globulin, IgG, IgM and antioxidants enzymes (TAC; SOD) were significantly increased in treated groups compared with control group. Significant decrease was observed in plasma lipids, cholesterol, triglyceride, lipid peroxidation (MDA) and transaminase enzymes (AST; ALT) resulted from adding propolis to chicks’ ration. Moreover, the intestinal total aerobic and anaerobic micro-flora counts and the count of total coliform were decreased with increase of propolis level. Generally propolis supplementation at any levels to chick’s diet improved net revenue and economical efficiency. In conclusion, supplemental propolis to chicks’ diet had a positive effect on growth performance, physiological, immunological and anti-oxidative status. Furthermore, addition 450 mg propolis/kg diet could be recommended for improving chick’s health and economic efficiency.

IMPACT OF STAR CRACK EGGSHELL TYPE AND LAYER BREEDER AGE ON EGGSHELL TRAITS, EMBRYONIC MORTALITY, HATCHABILITY AND CHICK QUALITY
Gamal
Rayan
Hatching eggs from Hy-Line W-36 strain were obtained from two layer breeder flocks differed in age (46 and 60 weeks). Eggs were randomly taken to evaluate impact of star cracks eggshell compared with normal eggs and layer breeder age on eggshell traits, embryonic mortality, hatchability and chick quality. Egg weight loss in star-cracked eggs was significantly higher than in normal eggs (P < 0.0001), the results indicated that egg weight loss increased with advancing breeder age. Hatchability percentage of chicks hatched from star-cracked eggs had lower in comparison with chicks from normal eggs. Percentage of hatchability decreases with advancing of breeder age for normal eggs (91.8 and 81.3 % at 46 and 60 wks of age, respectively), but this percentage remains almost constant with advancing of breeder age from star-cracked eggs (53.7 and 53.8 %, respectively). There were no significant differences among hatching egg type in terms of chick weight and percentage. The embryonic mortality had differed with different breeder's age. Highly increase in overall mean of embryonic mortality was observed in star crack eggs obtained from the two flocks. Chick length and shank length of chicks hatched from star-cracked eggs was significantly lower than those of chicks from normal eggs. Tona score as a quality indicator was significantly higher in chicks hatched from normal eggs (99.60 %) than those from star-cracked eggs (91.10 %). Blood biochemical parameters were not significantly differed in hatched chicks, except the plasma level of AST was significantly higher in hatched chicks from star crack eggs. Conversely, Cholesterol level was significantly higher in hatched chicks from normal eggs. Finally, This study showed that practically we can benefit from star-cracks eggs, because there is no significant difference between star-cracks and normal eggs for most eggshell characterstics, absolute & relative chick weight, and slightly difference for chick quality.

This experiment aimed to investigate the impact of Herbana administration on low-producer rabbit does during the last two weeks of pregnancy and the first two weeks after kindling on the growth performance and some physiological responses of their weanling rabbit kids.Forty-eight, 4 weeks old, female weanling NZW and V-line rabbit kids were equally divided into three experimental groups (16 kids each, 8 NZW+ 8 V-line). In the first group (Gr1-control), weanling rabbit kids produced from low-producer rabbit does (2-3 weanling kids/doe/parity), while those in the second group (Gr2) were produced from normal rabbit does (4-5 weanling kids/doe/parity). In the third group (Gr3), weanling kids were produced from does daily treated with 1.0g /doe of the Herbana.The achieved results showed significant breed differences in body weight (BW; P≤0.001) at different ages as well as in the daily feed intake (DFI) during 4-6 and 8-10 weeks of age. The means of feed conversion ratio (FCR) was significantly affected only at 4-6 weeks of age. Exposing female weanling NZW rabbits to heat stress significantly (P<0.05) decreased total protein (TP), albumin (Alb), globulin (Glb) and tri-iodothyronine hormone concentration (T3), while the mean of triglycerides (TG) significantly (P<0.05) increased than those of the V-line. Similarly, the means of rectal temperature (RT), respiration rate (RR) and ear temperature (ET) for V-line kids were significantly (P≤0.01) increased than those in NZW. Referring to Herbana administration, the means of BW, DFI, TP, Alb, T3 and thyroxin (T4) hormones increased significantly (P≤0.05) in the treated group, while the means of glucose (Glu), TG and total cholesterol (TC) were significantly decreased than those in the control group (Gr1). Similarly, the means of RT, RR, skin temperature (ST) and ET for rabbits in Gr3 were significantly (P≤0.01) decreased than those in the control group (Gr1).In general, it could be concluded that the DWG and DFI and physiological responses of NZW and V-line rabbits produced from low-producer rabbit does administered with Herbana significantly improved under heat stress conditions prevalent in Upper Egypt.

This study was designed to evaluate the effect of using bee pollen (BP) atdifferent levels as a natural growth promoter on the productive performance, digestibility,carcass traits, caecal microbial activity and some blood parameters of growing rabbits.Sixty New Zealand White (NZW) male rabbits, 5 weeks old were randomly divided intofour equal groups, with 695.75± 10.01 g BW. In the 1st group, rabbits were fed without anysupplementation and considered as control group. While, those in the 2nd, 3rd, and 4th groupswere daily treated with BP at 200, 500 and 700 mg/kg BW, respectively and served as low,medium and high treatment levels. From these findings could be noted that the growingrabbits treated with BP significantly (P≤0.05) increased final body weight and total weightgain and decreased feed intake (DM) as well as improved in feed conversion as comparedwith control group. Both of digestibility coefficients and nutritive values of treated rabbitswere significant (P≤0.05) improved than that of the control. The dressing weight, carcassweight and kidney fat were significantly (P≤0.05) increased with increasing BP levels.The immunoglobulin concentration (total antioxidants capacity, IgG, IgM and IgA)increased significantly (P≤0.05) with increasing BP levels. The amylase, lipase, andprotease activities were significantly (P≤0.05) increased in the pancreatic homogenate andintestinal contents in the rabbits treated with high levels of BP as compared to controlgroup. The best economical efficiency was obtained at the high BP level compared to othertreatment groups.Conclusively, from the obtained results it could be concluded that the supplementation ofBP at any levels studied had positive effects on rabbit’s performance, blood lipid regulationwhich reflecting their antioxidant of growing rabbits

The present study aimed to investigate the effect of different levels of ginger powder (GP) in Aged local cocks diets on semen quality and fertility rate under Egyptian summer hot condition. Eighty one 60-week-old Mandarah local cocks were utilized in a completely randomized design and were randomly assigned to 3 treatment groups (3 replicates of 9 cocks each) in an individual cages to receive 0.0, 2.5, or 5.0 g ginger root powder (GP) per kg diet for 12 successive weeks (60 to 72 weeks of age). The obtained results showed that dietary GP improved semen ejaculation volume, sperm motility, sperm cell concentration and live spermatozoa. Both levels of GP significantly (P≤0.01) decrease the percentage of sperm total saturated fatty acid and significantly (P≤0.05) increased the percentage of sperm total unsaturated fatty acid of seminal plasma as compared with the control group. Also, Omega 6: Omega 3 ratio was lower in the cocks fed 5.0 g GP/kg diet compared with those under 0 and 2.5 g GP/kg diet groups. Total antioxidant capacity (TAC) significantly (P≤0.05) increased. However, Malondialdehyde (MDA) level and sperm abnormalities (%) were significantly (P≤0.05) lowered in cocks treated with GP than untreated ones. Cocks fed 2.5 or 5.0 g GP resulted in a significant (P≤0.05) increase in fertility rate and hatchability/total eggs rates being 5.55, 14.28% and 14.05, 22.90 % respectively. While, hatchability/ fertility eggs and total embryonic mortality (%) were not affected. Add GP resulted in a significant improvement in the values of follicle-stimulating hormone (FSH), Luteinizing hormone (LH), and testosterone concentrations. It could be concluded that, supplementation of the cocks diet with 2.5 or 5.0 g ginger root powder (GP) per kg diet can be recommended for improving semen quality of and fertility rate especially with the fertility weakness in aged local cocks.

Countries having shortage in animal protein, such as Egypt can depend on intensive production of quail to compensate a part of this shortage. So, the present study was carried out at Poultry Farm, Faculty of Agriculture, New valley Branch, Assiut University, Egypt, to study the effect of different levels of yeast and supplementation of Hafsh (nonedible dates produced from dates factories) on performance and some physiological parameters as well as meat quality of Japanese Quail (Coturnix japonica). A total of 270 chicks, one week old unsexed Japanese Quails were weighed andrandomly assigned to 9 groups housed in 3 replicate pens with 10 birds in each. Nine different treatments in a 3 x 3 factorial arrangement including three levels of yeast (0.0, 0.5, 1.0 g yeast /L) in drinking water with three date residues levels (0, 5 and 10% ) supplemented into diets. The obtained data pointed out that the yeast level,hafsh levels and interactions between yeast level and hafsh level had a significant effect on growth performance (body weight, feed intake , body weight gain and feed conversion ratio), where there were growth performance of quail inhanced, and some internal members ratios in relation to live bird weight of Japanese Quail except spleen ratio was insignificant . Results showed that different treatments of yeast or date residues alone or with yeast at any level remark that significant (p<0.05) difference in some blood hematological ,biochemical parameters (total protein , albumin , total lipids , cholesterol and glucose concentration), liver function (AST and ALT), physical properties, chemical composition and sensory evaluation of breast and thigh muscles of quail meat. The counts of total aerobic and anaerobic bacteria and total coliform of chick intestinal were decreased due to add different treatments compared with the control . From the present work , it may be concluded that the application of 1.0g yeast/liter ( in water) with 10% hafsh (in feed) improved growth performance, some physiological parameters, carcass weight and nutrients digestibility, dressing%, breast weight%, thigh weight%, meat quality of Japanese Quail and is advisable.

The object of this study was to evaluate the effect of graded levels of olive leaves extract (Oleuropein) supplementation on layer hen performance. One hundred and forty four of Bandarah chickens (24 wks) were randomly distributed to four treatment groups of three replicates (10 hens and 2 cocks per each replicate), group 1 was served as a control group. Group 2, 3 and 4 were fed diets supplemented with 50.0, 100.0 and 150 mg Oleuropein /kg diet, respectively. Birds were reared in floored cages in an open system house under similar conditions of management up to 42 wks of age. Results revealed that egg production, egg mass and feed conversion ratio were significantly (p<0.05) improved for the all groups supplied with different levels of oleuropein compared with control group. While egg weight and feed consumption were not affected by supplemental oleuropein. Egg yolk color score was significantly (p<0.01) increasing for the groups fed oleuropein diets. The significant highest egg yolk color score was recorded for the group fed diet supplied with the highest level of oleuropein (150 mg/kg diet). Egg yolk cholesterol significantly (p<0.05) decreased for oleuropein treatments. Significant decrease was observed in saturated fatty acids of egg yolk in treated groups (100, 150 mg oleuropein). Also, results showed significant increase in yolk omega 3 and 6 fatty acids for the groups supplied with oleuropein. Adding oleuropein to hens ‘diets at any tested levels resulted in significantly (p<0.01) increased in plasma protein and globulin. The same result was observed in plasma T3, while blood albumin, glucose concentrations and the activity of AST and ALT enzymes were not significantly differed among the all experimental groups. Blood lipid profile for the groups fed diets supplied with oleuropein was significantly (p<0.01) improved compared with the control group. In accordance with hematological parameters, addition of oleuropein at different levels significantly (p<0.01) increased white blood cells (WBC) and lymphocytes count while heterophils count and H/L ratio significantly (p<0.01) decreased. The improvement of superoxide dismutase (SOD) and total antioxidant capacity (TAC) were significantly (p<0.01) for the groups supplied with different levels of oleuropein compared with control group. Decrement of plasma lipid peroxidation based on MDA was significantly (p<0.001) in treated groups compared with control group. In conclusion, olive leaves extract (oleuropein) supplied up to 150 mg/kg diet improved the performance, lipid profile, immunological and anti-oxidative statues of Bandarah laying hens.

saber
The present study was conducted to investigate the effects of dietary different levels of olive cake (OC) on laying hens' performance and some blood constituents under Egyptian desert conditions. A total number of 150 Mamora laying hens (22 weeks old and body weight of 1461.20 ± 30.74 g) were used until 34 week of age. One hundred and fifty hens were randomly distributed into five equal treatments (30 hens of each) and randomly distributed into three equal replicates (10 hens each). The 1st treatment was fed a basal diet as a control (0 % OC), while, the 2nd, 3rd, 4th and 5th treatments were fed diets containing 4, 8, 12 and 16 % OC, respectively.The results showed that hens fed 12 and 16 % OC recorded an increase (P<0.05) in egg weight by 4.9 and 2.9 %, respectively, while, shell thickness was decreased (P<0.05) in 8, 12 and 16 % OC as compared to control group. However, egg number was decreased (P<0.05) in 12 and 16 % OC as compared to those fed based diet.Hens fed 16 % OC showed a significantly decreases in the count of red blood cells, hemoglobin and albumin concentrations as compared to other treatments. While, diets containing 4, 8, 12 and 16 % OC significantly reduced the levels of cholesterol and triglycerides concentrations compared to the control group. Hens fed 16 % OC showed significantly increased in aspartic transaminase concentration as compared to other treatments, while, total antioxidant capacity was decreased (P<0.05) in the hens fed 16 % OC as compared to the hens fed 4 % OC and control group. Conclusively, olive cake could be successively and safely included up to 12 % in laying hens diets without adversely effect on productive performance and blood constituents under Egyptian desert conditions.
