Environmental Studies & Res. Instit., Univ. of Sadat City, Sadat City, Egypt.
In this study Jerusalem artichoke tubers powder (JA) as a source of prebiotics at 3% and 6% levels was supplemented in quail chicks, diet to determine the growth performance. An experiment of 42 days was conducted with a flock of 270 unsexed one- day old chicks, were used in a completely randomized design (CRD with 3 treatments and 3 replicates). Treatments were control no additive, T1containing 3% (JA), T2 containing 6% (JA). All chicks had free access to feed and water ad libitum during the 6-wk experiment. Weight gain (WG), feed intake (FI) and feed conversion ratio (FCR) were determined. At the end of experiment three birds per replicate were slaughtered. The results indicated that, chicks fed 3% and 6 % Jerusalem artichoke had higher body weight gain at 42 days and performance index also, lower feed intake; and better feed conversion ratio compared to the control group. Feeding diet containing 6% had the highest total serum protein, Glucose and AST concentrations; moreover were lower than in the control diet. No significant effect of different levels of Jerusalem artichoke on carcass characteristics was detected. Evidently, it may be concluded that the dietary supplementation of Japanese quail chicks with 6% Jerusalem artichoke resulted in considerable improvement in the growth and economic efficiency without adverse effects on carcass characteristics or constituents of blood serum.

A total number of 270 Domyati ducklings at 21-day-old were used, weighedand divided into five experimental groups to investigate the effect of dietary L-carnitine (LC)supplementation level (0, 150, 300, 450 and 600 mg/kg) on growth performance, carcassquality, hematological and blood serum constituents as well as economic efficiency insummer season. The results indicated that dietary LC supplementation resulted in asignificant (P≤0.01) improvement in live body weight at 63 and 84 day of age, while bodyweight gain, feed conversion ratio and production index were significantly (P≤0.01)improved as compared to the control group during the overall experimental period (21-84day of age). Eviscerated carcass and total edible parts (%) were significantly (P≤0.05)improved by supplementing different LC levels to the diet as compared to the control, butabdominal fat (%) was significantly (P≤0.01) decreased. Breast and thigh yield (%) weresignificantly (P≤0.01) higher for ducklings fed diets supplemented with 450 and 600 mgLC/kg than those fed the control diet. Dietary supplementation of different LC levels resultedin a significant improvement in muscles (%) for both breast and thigh, while skin withsubcutaneous fat (%) was significantly decreased as compared to the control. Dietarysupplementation of different LC levels resulted in a significant (P≤0.01) increase in crudeprotein and decrease in ether extract content for breast and thigh muscles than the controlgroup. Hemoglobin content was significantly higher for ducklings fed diet supplementedwith 300 up to 600 mg LC/kg as compared to those fed the control diet. Lymphocytes (L)cells (%) was significantly (P≤0.01) increased, while heterophils (H) cells (%) and H/L ratiowere significantly (P≤0.01) decreased for ducklings fed diets supplemented with differentLC levels than the control. Serum triglycerides constituent was significantly decreased forducklings fed diets supplemented with different LC levels than those fed the control diet,while, total cholesterol was significantly decreased by feeding these diets except for 150 mgLC/kg diet which was insignificantly decreased. Economic efficiency was significantlyhigher for ducklings fed diets supplemented with different LC levels, while, 300 and 450 mgLC/kg diet recorded the best values than those fed the control diet .

The present experiment was conducted during the summer months to studythe effects of glutamine injection glutamic acid and ascorbic acid supplementation and itscombination, on broiler performance, some physiological parameters and immune response.Moreover effects of these anti-heat stress agents on antioxidant system, heat shock protein70 and the relation between them was one of the aims of this study. A total number of twohundred and forty one day old Arbor Acres broiler chicks were individually weighed andrandomly divided into 6 treatments. Chicks in the 1st group fed control basal diet during 3rearing periods. Chicks in the 2nd group fed control basal diet supplemented with 1000 ppmglutamic acid only during starter period. Chicks in the 3rd group injected with glutamine in1day- old and fed control basal diet. Chicks in the 4th group fed control basal dietsupplemented with 40 ppm ascorbic acid during 3 rearing periods. Chicks in the 5th groupfed control basal diet supplemented with 1000 ppm glutamic acid during starter period + 40ppm ascorbic acid during 3 rearing periods. Chicks in the 6th group injected with glutaminein 1day- old and fed control basal diet supplemented with 40 ppm ascorbic acid during 3rearing periods. The results demonstrated that glutamine injection at 1day old and glutamicsupplementation during starter period improved body weight and body weight gain duringthe starter and finisher periods. Erythrocytes count, hemoglobin concentration andhematocrit values significantly increased when birds injected with glutamine and fed dietssupplemented with glutamic and ascorbic acids. Amino acids and ascorbic acidsignificantly increased lymphocytes and decrease heterophilus and H/L ratio. Glutathioneperoxidase significantly increased by amino acids and ascorbic acid, other plasmaantioxidant enzymes did not affect. Moreover MDA and TAOC significantly improved byglutamine injection and glutamic acid supplementation. Heat shock protein 70 improved byglutamic supplementation and glutamine injection. There were no differences in meatcholesterol profile between experimental treatments. Glutamine injection and glutamic acidsupplementation significantly decreased bacteria total count of meat and MDA significantlydecreased. The results of the present study suggest that single glutamine injection, glutamicacid and ascorbic acid supplementation able to improve broiler performance, cellularimmunity and activity of antioxidant system.

The main objective of this study was to investigate the effect of season and dietary L-carnitine (LC) supplementation on productive and reproductive performance of local duck breeds. A total number of 285 Domyati ducks (225 ducks and 60 drakes), 25-wk-old were taken for each experimental season (winter and summer). Ducks were weighed, divided into five experimental groups and fed diets supplemented with different LC levels (0, 150, 300, 450 and 600 mg/kg diet) during the experimental period (25-41 weeks of age) for each season.Results indicated that some studied productive traits such as egg number (EN), egg mass (EM) and feed consumption (FC) were significantly decreased for ducks reared in summer than those reared in winter season. Moreover, dietary LC supplementation resulted in a significant improvement in EN, EM, FC and feed conversion ratio as compared to the control group during the period of 25-41 weeks of age. Reproductive traits such as egg fertility and hatchability (%) as well as semen quality parameters ( ejaculate volume, sperms concentration and mass motility) were significantly decreased for ducks reared in summer season than winter, while these parameters were significantly improved by dietary LC supplementation as compared to the control. Blood hemoglobin (HB) and lymphocytes (L) cells (%) were significantly decreased, while white blood cells (WBC) and heterophils (H) cells (%) were significantly increased for ducks reared in summer season than winter. However, supplementing LC with 300 up to 600 mg/kg diet significantly increased HB and L cells (%), while it decreased H cells (%) and H/L ratio than the control. Serum triglycerides, total cholesterol levels and liver enzyme activities (ALT&AST) were significantly higher for ducks reared in summer than winter season, whereas, these parameters were significantly decreased by dietary LC supplementation except for serum triglycerides. All nutrients digestibility coefficient, total digestibility of nutrients and metabolizable energy (ME kcal/kg) were significantly decreased for ducks reared in summer than winter season except for nitrogen free extract, whereas, all pervious parameters were improved with or without significant effect by dietary LC supplementation. Feeding economic efficiency and net return were significantly improved for ducks reared in summer season and dietary LC supplementation as compared to the control.

This experiment was conducted to study the effect of probiotic supplement (contains Aspergillus awamori) on performance, egg production, egg quality and serum blood characteristics of quails. A total of 135 laying Japanese quails were randomly assigned to one of five treatments with three replicates (n = 9 quails per replicate). The experimental treatments were: the 1st group received a layer basal diet without supplement and served as control. The 2nd, 3rd, 4th and 5th groups were fed the control diet supplemented with 250, 500, 750 and 1000 mg Tomoko® (contains Aspergillus awamori)/Kg diet for 12 weeks through summer season. Results indicated that the supplementation of 750 and 1000 mg Aspergillus awamori/kg diet recorded a significant (P≤0.05) improvement in egg production by 8.4 and 14.9 % and eggs mass/hen/day (P≤0.05) by 5.0 and 10.7 %, respectively, as compared to the control. However, aforementioned groups improved feed conversion ratio, but differences were not significant compared to the control. No significant differences were observed in feed consumption and most of studied egg quality (egg, yolk and albumen weights, shell percentage, egg specific gravity, albumen index, and yolk index) among treatments. Laying quails fed with 1000 mg of Aspergillus awamori improved albumen height. Inclusion of Aspergillus awamori led to a greater egg shell weight, whereas egg shell thickness was improved in supplemented groups with 250, 500 and 750 mg Aspergillus awamori/kg diet as compared to the control. Yolk total lipids and total cholesterol was decreased significantly and the lowest value was observed in group given 1000 mg Aspergillus awamori/kg diet. Also, birds fed different levels of Aspergillus awamori in diet had serum low density lipoprotein values significantly (P≤0.05) lower than the control. Malondialdehyde (MDA) level of Aspergillus awamori supplemented groups was significantly lower than the control. However results showed insignificant increase in total antioxidant capacity and significant (P≤0.05) increase in glutathione peroxidase in the Aspergillus awamori groups. In conclusion, the results showed that supplementation of probiotic contains Aspergillus awamori improves performance, egg production, and antioxidant status as a feed additive in the diet of laying quails under summer conditions

In this experiment, Robadiar (R) or Orego-Stim (OS) foreign commercial products were used as a source of oregano. A total number of 165 Inshas strain birds (150 hens and 15 cocks) 24-wks-old were used in this experiment up to 40 wks of age. All birds were individually weighed and randomly divided into 5 equal experimental groups (30 hens and 3 cocks of each) with three replicates (10 hens and 1 cock each) with almost similar initial average body weight. Replicates were randomly housed in floor pens. The first group was fed the basal diet without supplementation and served as control. The second and third groups were fed the basal diet supplemented with 0.2 and 0.4g Robadiar/kg diet, respectively as a first source of oregano. The fourth and fifth groups were fed the basal diet supplemented with 0.3 and 0.6g Orego-Stim/kg diet, respectively as a second source of oregano. The results obtained could be summarized as follows: hens fed diets supplemented with either R or OS as oregano recorded the best values of egg production percentage, egg mass and feed conversion ratio than the control group. Hens fed on 0.4g Robadiar/kg diet (T3) recorded the better feed conversion ratio compared with other treatments (except T2 group) or control groups. Improvement was found in yolk% in hens supplemented with T3 group compared with other treatments or control groups. Adding oregano at different levels and types to layer diets significantly (P≤0.05) increased relative oviduct, the highest values were recorded by T3 group. There were significantly (P≤0.05) decreased relative abdominal fat due to adding oregano to layer diets, the lowest value was recorded in the third group. Both total anaerobic and Escherichia coli (E. coli) counts of bacteria were significantly (P ≤ 0.05) decreased, while lactobacillus count was significantly (P ≤ 0.05) increased by different types of added oregano when compared to the control group. Birds of T3 group had recorded the lowest counts of both anaerobic and E. coli bacteria, and the highest count of lactobacillus compared to other treatments. Each of plasma total lipids, total cholesterol, Triglycerides, high density lipoproteins and low density lipoproteins concentrations were significantly (P≤0.05) decreased by all the dietary treatments compared to control group. While, concentrations of plasma proteins and plasma of aspartate amino transaminase and alanine transaminase activities were not affected.

A total number of 198 local Sinai laying hens (180 female + 18 males), 24-weeks-old, were weighed and divided into six dietary treatments to investigate the effect of dietary different levels and sources of crude fiber on productive and reproductive performance and nutrients digestibility during the laying period (24-40 weeks of age). The birds were fed a control diet contained 3.5 % crude fiber (CF) while, the remaining treatments were given moderate levels of dietary crude fiber by suing different levels of sunflower meal (SFM) and olive cake (OK). Results obtained could be summarized in the following:1. The different levels of CF had significantly higher BW and CBW comparing with the control diet (3.2% CF) except for the diet contained 5.42% CF (8% OK).2. The inclusion of different fiber levels in the diets resulted in significantly decreased egg number/hen, while egg weight was significantly improved for the all dietary CF treatments compared to the control diet except for the diet contained 5.42%CF where it did not actually differ from control diet.3. Regarding to egg mass, no significant differences were found between the group fed diet contained 5.6 % CF and the control diet.4. Feed conversion ratio was significantly lower for the birds fed diets with different levels of CF than control.5. Diet containing 4.42%CF (7%SFM) resulted in a significant higher hatchability of set eggs compared to control and other treatments. In addition, the hatchability of fertile eggs tends to significantly increase in treatments fed 4.45, 4.42 and 5.6% CF (7% SFM, 4% OK and 7%SFM+4%OK) as compared to the control diet.6. Embryonic mortality significantly decreased by the diets contained 4.45, 4.42 and 5.6% CF compared to control group meanwhile the other treatment did not actually differ from control diet.7. All different levels of CF resulted in a significantly higher crude fiber and ether extract digestibility than control diet.

The purpose of this study was to testing the effects of spraying hatching eggs with some nutritive solutions i.e., vitamin C (Ascorbic acid, AA) and L-Carnitine (L-Car) on hatchability, embryonic mortalities, chick quality, some blood traits and post-hatch growth performance. A total number of 3600 hatching eggs were obtained from Cobb broiler breeder chickens at 35 wks of age. Eggs were randomly divided into 6 groups (600 eggs / group) with four replicates containing 150 for each. The eggs were sprayed during embryogenesis at 1st, 7th, 14th and 18th d of incubation. Eggs sprayed with AA and L-Car in: 1) no spraying without any supplementation (control group), 2) distilled water (sham group), 3) distilled water + 4 g/L AA., 4) distilled water + 6 g/L AA, 5) distilled water + 4 g/L L-Car, 6) distilled water + 6 g/L L-Car. At the end of hatching process, all un-hatched eggs were broken to estimate embryonic mortalities. Results revealed that spraying eggs with 6 g/L AA resulted in a significant (P≤0.05) improvement of hatchability traits. However, embryonic mortalities were almost significantly (P≤0.05) decreased due to application either AA or L-Car compared to control and sham groups. Furthermore, chick quality traits and subsequent growth performance markedly (P≤0.05) improved with application of nutritive solutions. Moreover, all blood traits were significantly (P≤0.05) affected due to positive effects of nutritive solutions, where the lowest corticosterone concentration observed for embryos resulted from eggs sprayed with either AA or L-Car, as judged by the decrease of stress. However, the highest RBC’s count recorded for chicks produced from eggs sprayed with 4 g/L AA, while, the highest value of hemoglobin concentration detected for chicks resulted from eggs sprayed with 6 g/L AA compared to other experimental groups. Furthermore, subsequent growth performance was severely improved due to spraying eggs with nutritive solutions. Most of carcass traits significantly (P≤0.05) affected due to spraying eggs with L-Car and AA, especially regarding with abdominal fat percentage, which significantly decreased. It could be concluded that, spraying hatching Cobb broiler breeder eggs with either AA or L-Car with doses 4 or 6 g/L on 1st, 7th, 14th and 18th d of embryogenesis markedly improved hatchability, chick quality traits and performance of progeny. Hence spraying eggs with these nutrients could be used as a successful method to reducing embryonic mortalities and improving early post-hatch performance.

This study was conducted to investigate the effect of supplementingginger and bee propolis as a growth promoter and antioxidant material on performance traits,carcass characteristics, blood parameters and antioxidant status of growing Japanese quail. Atotal of one hundred and thirty-five, 7 days old unsexed growing Japanese quails wererandomly divided into 5 groups, each 3 replication of 9 birds per replicate in a completerandomized design. Five diets were formulated as follows: the1st diet was basal diet withoutsupplement and served as negative control and the 2nd diet was basal diet supplementedwith 100 mg/kg antibiotic and served as positive control, while the 3rd and 4th diets included125 mg/kg ginger and 500 mg/kg bee propolis, respectively and the 5th diet included amixture of 125 mg ginger + 500 mg bee propolis/ kg diet. The results showed that dietarysupplementations did not significantly (P≤0.05) influence the final live weight and weightgain. Significant (P≤0.05) decrease in feed intake was recorded in the group receivedantibiotic and 500 mg propolis in their diet as compared to the control. Quails received 500mg propolis in their diet had the best (P≤0.05) record of feed conversion ratio. This groupsurpassed the control one by 4.2 %. The highest value of relative carcass weights wasobtained in the group received 500 mg propolis/kg diet. Numerical decrease was observedin relative weight of abdominal fat and numerical increase was observed in lymphoidorgans in all groups fed the different supplementations. Antibody titters against avianNewcastle disease significantly improved by different treatments at 21 days aftervaccination. Serum total lipids, triglycerides and total cholesterol were significantlydecreased for groups fed on different feed additives as compared to negative control group.Significant increase in HDL concentration was recorded in the groups given ginger orpropolis contained diets as compared to the control groups. Dietary treatments significantlyincreased total antioxidant capacity and glutathione peroxidase activity and significantlydecreased Malondialdehyde compared to the negative control. In conclusion, the resultsindicated that growing Japanese quail fed diet supplemented with ginger, propolis or itscombination could effectively be added to quail ration to improve feed conversion ratio andhumeral immunity and optimize lipid profile in blood serum and enhance anti-oxidativestatus.

This study was conducted to investigate the effect of supplementing bee propolis as a growth promoter and antioxidant material on laying performance, egg quality traits, blood parameters, antioxidant status during laying period of quails. A total number of 72 laying quails, 15-wks-old were randomly divided into four groups, 18 birds each, and each treatment replicated three times in a completely randomized design. The birds were selected on basis of more than 70 % egg production rate after two-week of observation period. Dietary treatments were as follows: control (without supplementation), bee propolis at levels of 250 and 500 mg/kg diet and ascorbic acid at level 250 mg/kg diet (as a positive control). Results showed that quails fed diets supplemented with different levels of propolis or ascorbic acid had similar body weight change, egg laying rate, egg weight and egg mass as compared to those fed the control diet throughout the experiment. Feeding quails on different levels of propolis or ascorbic acid in the diet improved feed conversion ratio, but differences were not significant compared to the control. All studied egg quality parameters were not significantly affected by different treatments. Yolk total cholesterol concentration was significantly (P≤0.05) lower for groups fed 500 mg propolis diet and this decrease reached to 3.6 % as compared to those fed the control diet, whereas, yolk total lipids were significantly (P≤0.05) decreased for groups fed ascorbic acid or different levels of propolis as compared to the control group. The decrease in yolk total lipids reached to 18.9, 23.5 and 10.2 % for the groups given 250 mg ascorbic acid, 250 and 500 mg propolis / kg diet, respectively. The studied serum constituents were significantly influenced for quails fed ascorbic acid or different levels of propolis diets. Feeding both ascorbic acid and propolis supplementation diets resulted in significantly lower total lipids, triglycerides, total cholesterol and LDL values than those fed the control diet. Malondialdehyde was significantly decreased whereas, total antioxidant capacity and glutathione peroxidase significantly increased in all treatments compared to the control. In conclusion, results indicated that propolis could effectively be added to quail ration to improve laying performance and to optimize lipid profile in egg yolk and blood and enhance the antioxidative status under summer conditions.

A total number of 180 Sinai laying hens at 25 weeks – old were used, weighed and divided into six treatments of three replicates each and housed in individual layer cages to investigate the effect of using two levels of energy (2760 or 2660 Kcal/Kg diet) and synthetic (s) or natural source (n) of Coenzyme Q10 (CoQ10) at levels of (0, 7.5 mg/kg diet CoQ10(s) or 7.5 mg/kg diet CoQ10 (n) ) in 2x3 factorial design on the productive performance, profile fatty acids in egg yolk, nutrients digestibility and economical efficiency of local laying hens. Resulted obtained could be summarized in the following:1- Egg weight of hens fed diet contained low ME significantly increased (P≤0.05) as compared to control diet. While, no significant influence (P≥0.05) of dietary CoQ10 and interaction between CoQ10 and ME on egg weight.2- Egg production % and egg mass for hens with low ME was significantly (P≤0.05) higher than hens fed diet with the control diet.3- Hens fed 7.5 mg CoQ10(s) had significantly higher (P≤0.05) egg mass by about 5.76% than CoQ10 (o) (control diet). The best egg mass was recorded by the interaction between 2660 Kcal / Kg and 7.5 mg CoQ10(s).4- Feed intake was increased by about 7.49% for hens fed the low level of ME (2760Kcal/Kg) as compared the control diet. While, the diet with CoQ10(s) was the highest amount of feed intake comparing with CoQ10 (n).5- Feed conversion was improved by 6.20% for hens fed diets with 2660 Kcal /Kg compared to 2760 Kcal /Kg. But, no significant influence of dietary CoQ10 and interaction between CoQ10 and ME on feed conversion ratio.6- The dietary supplemented with CoQ10(s) and the interaction between dietary CoQ10(s) or (n) + the low level of ME resulted in a significant increase (P≤0.05) in shell thickness compared to the control diet.7- The diet contained low level of ME caused a significant decrease (P≤0.05) in heterophil (H) % and heterophil / lymphocyte (L) compared to the control diet.8- The percentage of C18:2ω6 and C18:2ω3 with7.5 mg/Kg CoQ10 (n) is significantly higher (P≤0.05) than those of the control diet. On the other hand the percentages of C20:4ω6 was significantly reduced (P≤0.05) in response to the diet contained with7.5 mg/Kg CoQ10(s) comparing with the control and CoQ10 (n).

The main objective of this study was to increase the reproductive performance and profitability of pigeons by weaning of squabs at 3rd d post-hatching. If parents did not need to feed their squabs for about 28 d more eggs would be obtained from each pair of pigeons, where new laying cycle is initiated after weaning. In the first 3 d of life it is very difficult to weaning squabs because they completely dependent on pigeon crop milk (PCM), which contains immunoglobulin and other unknown compounds necessary for survival. However, at the end of 3rd d of nestling period crop milk replacer (CMR) can be made and successfully given for squabs till the end of growth period. A total number of 135 squabs (36.01±1.7g) were taken at the end of 3rd d post-hatching, which was randomly divided into 3 groups (45 squabs / group) with 3 replicates containing 15 squabs for each. The previous weaning groups compared with the PCM which contains 45 squabs leaved with their parents as a control group. The weaning groups were artificially fed by 3 different CMR containing 42.14, 44.15 and 48.12 % CP and 3277.5, 3308.7 and 3371.1 ME kcal/kg. Squabs were hand fed with CMR slurries composed of soya flour based diet, with added gluten, eggs, powder milk, yeast, and supplemental minerals, vitamins and oil. Eggs and powder milk were added to duplicate the nutrient composition of CMR. In the first stage of weaning (3 - 14 d), CMR were given for squabs containing 14% diet and 86% water by weight, followed by 20 % diet and 80 % water for the next growth period (15-28 d). Results indicated that early weaning is a new method to increase frequency of reproduction of parent stock, where annual squab production increased. Growth rate of weaning squabs was not negatively (P≤0.05) affected by hand feeding compared to PCM group. However, growth rate for either PCM or CMR groups was quick until d 14 and then progressively decreased afterwards, where the negative growth rate occurs at the 5th wk. There were significant (P≤0.05) differences observed for most blood parameters due to feeding CMR. While, insignificant differences observed for most carcass traits, with exception of body weight, spleen, wing and abdominal fat weight percentages. However, CP % and EE % in whole carcass insignificantly affected due to feeding CMR. In general, it could be concluded that squabs have been successfully hand-reared by using CMR, where the major benefit seen with the applying early weaning is providing an economical benefit by allowing more squabs at the end of the year and increase overall fecundity.

The aim of this study was to evaluate the effect of adding protease enzyme to low protein corn-soybean meal broiler diets to reduce feeding cost and improve the quality of meat. Two hundred and forty 1-d old unsexed Arbor Acres broiler chicks were distributed to six treatments (2*3 factorial design) of 4 replicates each. Two levels of protease activity (without and with 300 000 U/kg of the diet), and three levels of dietary crude protein were examined (Standard, STD; less 10% or less 15% from STD protein recommendation of each feeding phase, L10 and L15, respectively). The dietary protein levels were 23, 20.7and 19.5% at the starter phase; 21, 18.9 and 17.8% at the grower phase; and 19, 17.1 and 16.1% at the finisher phase. Diets were formulated to save the strain requirements of all other nutrients. All chicks were housed in open system broiler house and received the same managerial conditions and veterinary program during experimental period (1-40 d of age). Parameters of growth performance, carcass characteristics, physical and chemical evaluation of broiler meat were carried out and feeding cost was calculated. The recorded results showed that using protease improved final body weight (4.1%) and feed conversion ratio (6.1%) and reduced skin% of drum stick significantly (P<0.05). Decreasing protein of diets to (L15) increased consumed feed, drip loss of thigh, and back quarter weight (thigh and drumstick). Also, skin and pH of breast and concentrations of low density lipoprotein and malondialdhyde (MDA) in broiler meat were depressed significantly (p<0.0001). Among all treatments results showed that adding protease to L10 diets recorded the same marketing weight (2015 g), made broiler meat healthier (MDA decreased by 36%), and depressed the feeding cost/kg of life body weight by 3.94% relative to value calculated for STD group. Generally it could be concluded that adding 300,000 U protease enzyme/kg to low protein broiler diets could help producers to achieve acceptable marketing weight, get better meat quality, and reduce feeding cost according to Egyptian prices of feed ingredients.

This study was conducted to determine the effect of low or high proteindiets with constant ME on growth performance, carcass characteristics, digestibilities andblood parameters of Cobb Avian 48 broilers from 1 to 34 d of age. A total number of 2080one-day-old chicks were housed randomly in 16 pens and divided into two experimentalgroups, each group divided into 8 replicates and each replicate has 130 birds/ pen. All birdswere fed pre-starter diet (CP, 23% and ME, 2950 kcal/kg) for 4 days then the birds weredivided into two experimental diets which were formulated to have 2 levels of CPrespectively, in each phase: 22 and 21% CP with 3050 kcal/kg in the starter phase (5 to 10d); 20 and 19% CP with 3100 kcal/kg in the grower phase (11 to 25 d); and 19 and 18% CPwith 3180kcal/kg in the finisher phase (26 to 34 d). Digestible Lysine was maintained at1.22, 1.12, and 0.96% of the diet in the starter, grower, and finisher periods, respectively.Body weight gain, feed intake and feed conversion as well as thigh and liver weights werenot influenced by changing protein level in the diets. However, carcass weight and breastmuscle weight were increased significantly (P≤ 0.05). On the other hand, abdominal fatweight was deceased (P≤ 0.05) by feeding low protein diet. Although, dry matter and crudefat utilization were not affected, while, crude protein and crude fiber utilization wereimproved by feeding low protein diets. Plasma GOT, GPT and total cholesterol were notchanged, while; plasma HDL was increased by feeding low protein diets. Furthermore, itwas observed a decrease in muscle and liver MDA by feeding low protein diets, indicatingthe improving of the anti-oxidative activities by decreasing the protein content in broilerdiets. Economic efficiency was improved by feeding low protein diets compared to highprotein diets. In conclusion, feeding Cobb Avian 48 broilers on 1% lower protein diets thanthe strain recommendation, at constant ME, with the same amino acids levels had notadversely affected the growth performance, carcass parameters and liver functions, while;dietary crude protein and crude fiber utilization were improved.

This experiment was conducted in Inshas Poultry Research Station, Ministry of Agricultural, Egypt, A total number of 420 hens and 105 cocks from Silver Montazah chickens (SM) (Egyptian local strain) flock were used to investigate the effect of dietary supplemental of arginine (Arg) levels on plasma nitric oxide (NO) and Insulin-like growth factor (IGF-I), testosterone (Testo) and luteinizing (LH) hormones concentrations, and their relation to productive and reproductive performance during laying period (28-40 wks of age). Birds were randomly divided into 7 experimental groups (each of 3 replicates). Each replicates consisted of 20 hens and 5 cocks. The 1st group (T1) was fed the basal diet and served as the control group with no additional Arg (15, 12.5 and 12.8 g Ar /kg diet) for the starter, grower and finisher diet, respectively. The 2nd, 3rd and 4th groups were fed the basal diet supplemented with 2, 2.5 and 3 g Arg/kg diet, respectively, from one-day old to 40 wks of age (17, 17.5 and 18 g Arg /kg diet) for the starter, (14.5, 15 and 15.5 g Arg /kg diet) for the grower and (14.8, 15.3 and 15.8 g Arg /kg diet) for the finisher diet was used. However, the 5th, 6th and 7th groups were fed the basal diet (15 g and12.5 Arg/kg diet) for the starter, grower diet and the basal diet supplemented with 2, 2.5 and 3 g Arg/kg diet (14.8, 15.3 and 15.8 g Arg/kg diet) for the finisher diets, respectively, only from 28 to 40 wks of age. Results indicated that hens fed Arg supplementation significantly improved feed conversion ratio (FCR) for all treatments except T2 and T3 groups in compared with control group. Egg production, egg mass and total leucocytes count was higher in treated hens from 28 to 40 wks of age than in control ones. Most semen quality parameters, fertility, hatchability and lymphocyte (L) ratio were improved by dietary treatments. However, hetrophils (H) and H/L ratio were decreased by Arg supplementation. Significant increase (P≤0.05) appear in NO trait, IGF-I, LH and Testo hormones concentrations for hens in T6 and T7 from 28 to 40 wks of age in compared with treated hens from one-day old to 40 wks of age (T2, T3 and T4) and the control group. While, there were no significant differences in live body weight, feed consumption, egg weight and egg quality traits among all treatments in compared with control group at 40 wks of age. It could be concluded that dietary Arg supplementation to SM hens from 28 to 40 might improve the egg production, reproductive performance and some semen quality parameters. Also, it might have a mediated effects on NO, IGF-I, LH and testosterone hormones levels.

This experiment aimed at investigating the effects of milk thistle seeds (MTS) and rosemary leaves (RL) at 5 and 10 g/kg diet as feed additives on semen quality, blood metabolites and reproductive performance on rabbit bucks. A total number of 35 male V-line rabbit bucks were distributed randomly into five experimental groups of 7 bucks each. The 1st group, which served as a control, did not supplement with MTS and RL in their basal diet. The 2nd and the 3rd groups were supplemented with MTS at 5 and 10 g/kg in their basal diet, respectively. The 4th and the 5th groups were fed the basal diet supplemented with RL at 5 and 10 g/kg, respectively. The best sperm concentration (SC), total sperm output (TSO), live sperm (LS), total live sperm (TLS) and total motile sperm (TMS) were obtained from bucks fed MTS at 10 g/kg diet followed by RL at 5 g/kg diet. Bucks received MTS 10g/kg diet significantly increased their blood serum testosterone compared to the control and this was associated with a significant increase in the fertility rate of the 10 g MTS group. In addition, RL at 5 g/kg significantly increased blood serum testosterone and fertility compared to the control, but the MTS group had the highest serum testosterone and fertility. In conclusion, MTS and RL at 10 and 5g/kg, respectively, significantly improved antioxidant status and liver markers, which led to a significant increase in semen quality and fertility in rabbit bucks.

This study was conducted to investigate the effects of incorporating differentginger forms and levels on the growth performance, physiological and immunologicalresponses of broiler chickens exposed to chronic heat stress and the consequent effects onantioxidant status and microbiological traits of chilled and frozen meat. Two hundred andeighty broiler chicks were randomly distributed into to 7 dietary groups with 4 replicates(10 chicks each). Group one (control) fed corn-soybean meal basal diets which met thestrain requirements during starting, growing and finishing periods. Groups 2, 3 and 4 fedcontrol diet supplemented with 1%, 1.25% and 1.5% ginger aqueous extract respectively.Groups 5, 6 and 7 fed control diet supplemented with 100 mg, 150 mg and 200 mg gingeroil extract/kg diet respectively. Control group had significantly (P ≤ 0.05) the lowest bodyweight and body weight gain during grower period. The results indicate the accumulativeeffect of ginger in improving live body weight. Feed intake was significantly influenced bytreatments only during starter period, in contrast feed conversion significantly influencedduring the different periods. Neither level nor form of ginger affected hemoglobin,hematocrit, MCHC, heterophilus, heterophilus/lymphocytes ratio (H/L) and antibody titeragainst NDV and H5N1.Ginger aqueous extract caused significant (P ≤ 0.05) decreases inlymphocytes ratio compared with oil extract. Ginger forms significantly influencedbacterial total count, staphylococcus aureus, total coliform count and faecal coliform ofboth, chilled and frozen meat, where ginger oil extract recorded significantly (P ≤ 0.05)lower values than ginger aqueous extract. Influences of ginger forms and levels onantioxidant status of chilled and frozen broiler meat were insignificantly. Experimentaltreatments had significantly lower 2-thiobarbituric acid-reactive substance TBARS thancontrol treatment of both chilled and frozen broiler meat. Treatment groups recordedsignificant decrease in total bacterial count and insignificant decrease in staphylococcusaureus, total coliform count and faecal coliform. In conclusion, the results of this studysuggested that ginger supplementation in different forms and levels improved broilerperformance, physiological and immune responses and quality of chilled and frozen meat.Although, we suggest that more studies are needed to determine the effect of combinationof ginger oil and aqueous extracts supplementation.

Two hundred and forty, one day old unsexed Arbor Acres broiler chicks wereused to examine the effect of supplementing pectinase enzyme (PE) with varying levels ofmetabolizable energy (ME) on growth performance, quality of carcass and meat, and feedingcost. Chicks were randomly allocated into six treatments (2x3 factorial design) each had fourreplicates (n=10). Chicks were fed corn-soybean diet supplemented with two levels ofpectinase enzyme (0 and1000 U/kg), and three ME levels which were standard strainrecommendation (STD), 100 kcal lower than STD (E100) and 150 kcal lower than STD(E150) of each feeding phase. The dietary ME values were 3000, 2900 and 2850 kcal/kg dietat starter phase; 3100, 3000 and 2950 kcal /kg at grower phase; and 3200, 3100 and 3050kcal/kg at the finisher phase. All diets were formulated to save the strain requirements fromthe rest of nutrients. All chicks were housed in open system broiler house and received thesame managerial conditions and veterinary program during experimental period (1-40 d ofage). Parameters of growth performance, carcass characteristics, physical and chemicalevaluation of broiler meat were carried out and feeding cost was calculated.The recorded results showed that, pectinase (PE) supplementation could not change growthperformance significantly, while values of breast pHu, drip loss % of thigh and total protein(TP) of broiler meat were increased. Among ME levels, the reduction in ME of diet by 150kcal/kg led to significant reduction of final body weight, while the reduction in ME by 100kcal/kg led to significant reduction of abdominal fat %. Values of breast pHu, MDA and LDLof broiler meat at 40 days of age decreased significantly by the reduction in ME at both level(E100 and E150), while values of feed intake, feed conversion ratio, breast meat yield%,thigh%, drum stick %, drip loss % of breast and TP of broiler meat were increasedsignificantly compared with STD values. Among all treatments the results showedsignificantly effected on growth performance, carcass and meat quality parameters.Calculation of feeding cost showed that STD group recorded the lowest value than othertreatments. The overall results of PE and ME indicated that both could not improve growthperformance parameters and feeding cost, while the quality of carcass and meat wereenhanced. Applying E100+PE diets could help producers to get acceptable marketing weightwith better carcass and meat quality.

The main objective of this study was aimed to investigate the effects of different ambient temperature {normal temperature (NT) and heat stress (HS) conditions} and dietary supplementation of different selenium (Se) source (inorganic , organic and Nano Se) on some productive performance and physiological parameters for Sinai chickens during growth period and A total of 198, 8-wks-old of Sinai chickens were used and randomly distributed into two experimental groups (NT& HS), and then each group was divided into three sub-groups (inorganic , organic and Nano Se) in a factorial design (2x3). Chickens fed diet naturally contaminated with Aflatoxin (AFB1),7.50 μg/kg DM.The results indicated that heat stress resulted in a significant decrease in body weight and gain, feed intake and feed conversion. Lymphocytes (L) cells (%), plasma total protein and albumin were significantly decreased for chickens reared under heat stress, however, hemoglobin (Hb) concentration, white blood cells count, eosinophils cells (%), monocytes cells (%),globulin, calcium and phosphorus were not significantly affected. Moreover, a significant increases were recorded for red blood cells (RBC) count, heterophils (H) cells (%) , H / L ratio, plasma total antioxidant capacity (TAOC) and heat shock protein 70 for Sinai chickens reared under heat stress than those reared in thermo neutral during all the experimental periods.Supplementing different selenium sources to the diet had no significant effect on body weight and gain, rectal temperature and respiratory rate, albumin, calcium, phosphor and heat shock protein 70 for Sinai chickens than those fed the control diet. Moreover, feed intake, plasma H (%), and H / L were significantly decreased as a result of supplementing Nano selenium to the diet during the periods of 12-16 and 8-16 wks of age than the control. While, feed conversion was significantly improved by supplementing different sources of Se to Sinai chickens diet than the control. Significant increases were recorded in RBC count, Hb concentration and L cells (%), total protein, globulin and total antioxidant capacity for Sinai chickens fed diet supplemented with Se as compared with those fed the control diet. These results indicated that heat stress severely reduced productive and physiological performance for Sinai chickens, whereas the productive and physiological performance was improved by dietary Se sources supplementation under heat stress.
