Inshas strain of chicken was subjected to one cycle of early selection for body weight, keel length and breast circumference effect on egg production traits. Best linear unbiased prediction (BLUP) was used for predicting the breeding values and ranking then selecting hens. The selection differentials in G1 were equal to 2.6, 16.7, 72.4, 58.7 g, 0.1, -0.1, 0.6 cm, -9.0 g, 12.0 d, -16.0 egg, 0.6 g, -668 g, -17.0 egg, 1.9 g and -731 g for body weight at hatch (BWH), body weight at 4 weeks of age (BW4), body weight at 8 weeks of age (BW8), body weight at 12 weeks of age (BW12), Shank length (SL), Keel length (KL), Breast circumference (Br), body weight at sexual maturity (BWSM), age at sexual maturity (ASM), egg number at 90 d of production (EN1), egg weight at 90 d of production (EW1), egg mass at 90 d of production (EM1), ), egg number at150 d of production (EN2), egg weight at 150 d of production (EW2), egg mass at 150 d of production (EM2), respectively. These values in stander units were equal to 0.9, 0.3, 0.5, 0.4, 0.01, -0.2, 0.3, -0.06, 0.77, -3.5, 0.15, -3.7, -1.5, 0.5 and -1.3, respectively. The realized genetic gain exceeded the expected genetic gain for BWH, BW4, BW8, BW12, SL, Br, ASM and EW2 2.4, 13.7, 51.9, 39.9, 0.3, 1.4, 5.4, 0.7 vs. 2.0, 3.9, 19.0, 11.0, 0.1, 1.0, 1.9 and 0.1. From the results of the present study, selection was effective in improving body weight traits by the generation (G1) of study. The heritability estimates in this study were moderate to high for most of the traits studied. This is an encouraging factor for more intense selection within the Inshas local chicken population.

This study was performed to evaluate the protective effects of feeding reduced glutathione (GSH) against hepatic dysfunctions related to dietary aflatoxicosis in Inshas chickens (a local Egyptian chicken strain). 5 ppm of GSH were used with 500 ppm of aflatoxin B1 (AFB1) /kg diet administrated. In total, 96 chickens were divided into 4 treatments with 3 replicates. T1 was the negative control. T2was the positive control group (AFB1). Groups T3 and T4 were administrated with GSH, and GSH+ AFB1, respectively. At the end of the experiment (28-38) wk of age, samples were collected for analysis. The results showed that AFB1 has significant potency for increasing aspartate transaminase (AST), creatinine in blood, thiobarbituric acid reactive substances (TBARS) in muscle , while reducing the plasma α-tocopherol content, antioxidants enzymes (glutathione peroxidase (GSH-Px), catalase (CAT), superoxide dismutase (SOD) and total antioxidant capacity) in blood of chicken. In addition, the negative effects of AFB1 on mRNA for antioxidant enzymes (GPX, SOD and CAT), hepatosomatic index (HSI), lipid peroxidation on birds aflatoxicosis were recorded in this study, also the efficacy of GSH for ameliorating aflatoxicosis were recorded. Moreover, these results showed that the ability of GSH when use with aflatoxicosis to counteract the toxic effects of AFB1 on chickens. Additionally, the GSH-Px (T3) were enhanced the antioxidative status. Finally, the optimal levels of GSH and method of used for detoxification of aflatoxin effects need more studies.

Anim. and Fish Prod., Fac. of Agric. (Saba Basha), Alexandria Univ., Alexandria, Egypt
A total number of 144 Japanese quail birds (96females and 48males) at 12 weeks old were used to evaluate the physiological value of taurine supplementation to plant protein diet on laying quail performance. Quails were weighed individually, randomly distributed into four experimental groups; each group contained 36 birds (24 hens and 12 males). Two different basal diets were formulated; the first one containing fish meal (animal protein diet, AP) and fed to the first treatment (T1), another one was containing corn-soybean (vegetarian protein diet, VP) and fed to the second treatment group(T2). The third and fourth treatment groups (T3 and T4) were fed the second diet (VP) with taurine addition 0.15 and 0.30 % (VP0.15 and VP0.30, respectively). The results indicated that hens fed taurine supplementation (T3 and T4) to the VP numerically improved egg laying rate, egg number and egg mass while, egg weight was numerically decreased. Heterophils (H) and H/L ratio were significantly (P≤0.05) increased for the hens fed T3 as compared with those fed T1 and T2. Antibody titter against avian Newcastle disease at 14 days post-vaccination was significantly (P≤0.01) increased for the hens fed T1and T4 as compared with those fed T2 and T3 diets, while at 21 days post-vaccination it was significantly (P≤0.01) decreased for the hens fed T2 as compared with those fed T1 and T4. Serum lipid profile was improved in T3 and T4 in comparison with T1. Lipid peroxide concentration was significantly decreased, total antioxidant capacity was significantly (P≤0.001) increased in VP diets in comparison with AP diet and the improvements were pronounced with including taurine in VP diet. In conclusion, taurine supplementation for laying Japanese quail fed vegetarian protein could improve immune response, antioxidative properties and decreased blood lipids profiles.

The aim of this work was to study the efficacy of AGP alternatives supplementation in the diet on broiler performance, intestinal morphology, cecal microbiota and carcass traits. Three hundred seven-day old broiler chicks (cobb500), un-sexed of 160gm average body weight, were randomly divided into five experimental treatments and three replicates per treatment group. Antibiotic and Coccidiostate-free commercial diets cover the broiler recommendation during each growth phase were used. Each group was fed on one of the following experimental diets: TC- basal diet (control), COA-basal diet + Coated Organic Acids Mixture 750gm/Ton, OA- basal diet + Organic Acids Mixture 750gm/Ton, (EO)-basal diet + Encapsulated blend of Essential oils 100gm/Ton, PRO-basal diet + Probiotic 500gm/Ton.At 42 days results revealed that, supplementation of broiler diets with COA and EO led up to insignificant numerical increase in BWG by 3 and 1.9 % , respectively compared with the control group. There were insignificant numerical improvement in CFCR by 6.4, 2.46, 5.4 and 4.43% for COA, OA, EO and PROgroups, respectively. Supplementation of broiler diets with COA vs.OA improved BWG and FCR by 5 and 4%, respectively. Treatments had no effects on dressing percentage and meat yield At 42 days of age, all AGP alternatives supplementation tended to increase the number of Enterrococci and lactic acid bacteria group and to decrease the numbers of E. coli group in compared with the control group. However, the Cecal digesta pH tended to be similar in treated birds in compare with control group. At 42 days of age, birds fed OA diets had the longer and wide jejunum villi (the height and the area of the villi increased by 17 % and 23.3%, respectively) deeper crypts (increased by 26.6%) and lower jejunum mucosal layer thickness (39.1 % lower) in compared with control group.Broilers fed diets supplemented with COA, EO and PRO tend to improve PCR by 6.5, 5.6 and 4.79, respectively and EPEF by 12.0, 9.5 and 1.74% in compared with those fed the control diet.

The present study was carried out to investigate the effect of different dietary fiber levels in local Sinai cocks diets on the reproductive and economic performance during the period from 15-40 wks of age. Eighteen Sinai cocks were randomly assigned to different levels of crude fiber. The basal diet contained 3.65% crude fiber and the experimental treatments were given higher levels of crude fiber as a result of usage different levels of sunflower meal, olive cake and combination between them. While, all hens (180 female) were fed layer diet contained 17% crude protein and 2750 Kcal/Kg diet ME. Results of the current study are summarized as follows:1. The cocks fed diet contained 5.9 and 4.65% CF (14 and 7% SFM) recoded the lowest live body weight, and also resulted in a significantly decrease (p≤0.05) in body weight gain compared to the control diet.2. The mass motility of sperms was significantly increased (p≤0.05) by about 16.28% of males fed diet contained 6.02 % CF (7% SFM+5%OK) comparing with control diet.3. Both progressive motility and sperm concentration were improved by increasing dietary CF from 3.65% (control) to 6.02 % (7% SFM+5%OK).4. The fertility% was significantly improved (p≤0.05) in eggs from hens that were inseminated by cocks fed diet contained 5.9% CF (14% SFM) by about 7.89 % compared to the control diet.5. The hatchability of set eggs % was significantly increased (p≤0.05) by feeding diet contained 5.9 5% CF (14% SFM) comparing with the control diet followed by those fed diet with 5.45% CF and 4.77% CF (7% SFM and 5% OK).6. The diets contained 4.77 and 6.02% CF (5% OK and 7% SFM +5 % OK) resulted in a significant increase (p≤0.05) the hatchability of fertile eggs % by about 3.38% as compared to the control group.7. The diet contained 5.95 CF (14% SFM) resulted in significantly improved (p≤0.05) economic efficiency of hatchability of set eggs compared with the control diet.The present study illustrates that local Sinai cocks require a moderate levels of crude fiber in diets ranged from 4.65 to 5.95 % from (5 % Ok, 7% and 14% SFM) during the period from 15 to 40 weeks of age for optimal the reproductive and economical performance.

The aims of this study were investigated the effects of crossing between Saso cocks (S) with each of Alexandria (A) and Fayoumi (F) hens on body weight at different ages and some egg production traits for two crossing generations. Data of 954 chicks were produced during 2 generations of different crossing S×A, S×F, SA×SA, SF×SF, SA×SF and their reciprocal crossing SF×SA. These data were presented different genotype groups of males and females for base and two crossing generation. The main results are summarized as follows:1. The estimates of heterosis (H%) for a cross (♂S X ♀F) were -7.01, -35.62, -27.35and -27.20% for BW0, BW4 , BW8 and BW12 respectively.2. The cross SF was superior to Fayoumi (native breed) by 12.6, 85.9, 109.6 and 128.9% for BW0, BW4, BW8 and BW12 respectively.3. The estimates of heterosis (H%) for a cross (♂S X ♀A) were - 6.32 , -34.61, -29.78 and -24.19% for BW0, BW4 , BW8 and BW12 respectively.4. The cross SA was superior to Alexandria (local improving strain) by 8.8, 87.8, 104.1 and 133.0% for BW0, BW4, BW8 and BW12 respectively.5. In second crossing generation, the estimates of heterosis (H%) for a cross (♂SA X ♀SF) and a reciprocal cross (♂SF X ♀SA) were approximately same values for body weight at different ages and egg production traits.6. Negative estimates in a second crossing generation for most of studied traits were shown that the second - crosses SF and SA were more better than the third – crosses which produced of crossing (♂SA X ♀SF) and their reciprocal crossing (♂SF X ♀SA).

The aim of this study was to evaluate the influence of supplementing diet with propolis on Bandarah laying hens’ performance. A total of 120 laying hens and 32 cocks at 30 weeks of age were randomly distributed among four treatments groups with 3 replicates each (10 females and 1 male/replicate) were housed in floor pens (2.5x1.5x2.5m).Birds in group 1 were fed a basal diet and considered as control group, while those in groups 2, 3 and 4 were fed on the same basal diet supplemented with 150,300 and 450 mg propolis/kg diet during experimental period (30-42 weeks of age). Results indicated that egg weight, egg production % and egg mass for propolis treatments were significantly (p<0.01) increased than those fed control diet. Feed consumption was not affected by supplemental propolis, while feed conversion ratio was significantly improved compared with control group. Shell thickness, Haugh unit score and egg yolk % significantly improved for hens fed diet supplemented with propolis compared with control group. However, egg shell %, shape index, yolk index, albumen % and yolk color score were not affected by propolis supplementation. In accordance with hematological parameters, addition of propolis at different levels significantly (p<0.01) increased Hb, PCV, RBC, WBC, lymphocytes count while heterophils count significantly (p<0.01) decreased. There was significant increase in plasma total protein, globulin, IgG and IgM with increasing propolis level. Lipid profile, Liver and kidney function significantly (p<0.01) improved for propolis treatments. Significant decrease was observed in plasma lipid peroxidation based on MDA levels in treated groups compared with control group also, results showed significant increase in antioxidants enzymes (TAC and SOD) for the groups supplied with propolis. Moreover, supplementation diets with propolis at different levels significantly improved semen quality, fertility and hatchability percentages compared with control. In conclusion, the results indicated that supplementation of propolis to Bandarah chickens diets significantly improved productive, reproductive, physiological, immunological and anti-oxidative status.

The aim of this study was to investigate the effect of age and supplementation with vitamin E and selenium combination on semen characteristics of New Zealand White (NZW) rabbit bucks. Thirty six NZW rabbit bucks were divided into three equal experimental groups according to their age. Group 1: young age (4-5 months), Group 2: middle age (9-10 months) and Group 3: old age (20-24 months). Each group was divided into two subgroups (treatment and control).Treated group was subcutaneously injected with 50 mg vitamin E and 0.1 mg selenium per kg live body weight, while the other was given saline solution and served as control. Experimental animals were injected once a week for 12 weeks. After six weeks of treatments, semen was collected weekly for six successive weeks. Reaction time was recorded; semen characteristics and plasma testosterone were estimated. Results showed that the young age group had significantly (p < 0.05) lower sperm cell concentration/ml, total motile sperm/ml and insignificantly lower initial motility and sperm viability than those recorded in other ages. The middle age group had significantly (p < 0.05) higher whole ejaculate volume than other groups. Also, they had significantly (p < 0.05) higher sperm membrane integrity and significantly (p < 0.05) lower fructose level than those recorded in the old age group, but not significant with the young age group. Animals treated with Vit. E and selenium showed significantly (p < 0.05) improvement in most semen quality traits compared with control animals. Averages of sperm viability, motility, sperm concentration, total motile sperm per ml, ejaculate volume, sexual libido and sperm membrane integrity were significantly higher in bucks received Vit. E and selenium than those recorded in control bucks. In addition, best results were observed in the middle age group, meanwhile, semen characteristics of young and old rabbit bucks did not decrease dramatically and still in acceptable range. It could be concluded from our study that young and middle age bucks with supplementing with Vit. E and selenium could be used successfully and efficiently in rabbit breeding systems.

Total numbers of 300 growing V. and Alex. rabbits at age of 4-weeks were used to study the effect of dietary potato peels as a partial replacement at levels 5, 10, 15 and 20% of dietary fiber inclusion. Rabbits of each line were randomly classified into five equal groups (30 each). The 1th group received the basal diet and served as control diet. The other four groups received the basal diet with replacement potato peels meal at the studied levels, respectively. The chemical composition of the potato peels meal clearly shows that it contains 14% crude protein, 15.6% crude fiber and 57.1% nitrogen free extract and these compounds falls within ranges of studied wheat brain and Alfalfa hay. While, ether extract and ash content of potato peels meal were higher than those of other studied materials. Significant difference was recorded for body weight, gain, feed intake and feed conversion as a result of lines difference over all the experimental growth period (4-10) week old. In that, average body weight of Alex. rabbits and its gain were higher than those of V. line. The opposite was true with feed intake, where rabbits of V. line consumed more diet compared with those of Alex. line. Dietary potato peels meal treatments (10%) significantly increased body weight and weight gain and consequently feed intake was also increased. Meanwhile, the best score of feed conversion was attained with Alex. rabbits fed inclusion level of 10% potato peels meal. This trend did not continue but it significantly decreased as increasing inclusion level up to 20% and resulted to impaired feed conversion which being 3. 89 for V. rabbits and followed by 3.37 for Alex. rabbits. The relative economic efficiency of the different formulated diets as affected by dietary treatments of 5 and 10% were highly by 8.9 and 16.1% over the corresponding of the control group for Alex. rabbits and followed by 7.2 and 5.5% over the control group of V. rabbits, respectively. In conclusion, potato peel meal can be used as a good alternative source of fiber at levels of 5 and 10% in growing V. and Alex. rabbits diets, respectively with a good influence on productive performance and can be considered a cheap of fiber ingredients in rabbits diets formations.

A total of 24 primiparous rabbit does of California (CAL) breed in three different reproductive statuses were used to assess the profile of some physiological, biochemical and hormonal parameters. The 3 reproductive statuses were before mating, during pregnancy and after parturition. Feed and water were provided ad libitum. Does body weights were weighed weekly. Rectal temperatures (RT), respiratory rate (RR) and pulse rate (PR) of does were recorded every other day. Serum total protein, albumin, cholesterol, glucose, urea and creatinine concentrations were determined twice a week. Growth hormone (GH), Estrogen (E2), Progesterone (P4), and Triiodotheronine (T3) were determined in rabbit does within each of the 3 physiological statues.
Body weight increased in pregnant rabbits than those before pregnancy and after parturition. No significant variations were found among biochemical parameters during these 3 physiological conditions except for albumin value that was lower after parturition in comparison to the other 2 status. No significant differences were observed in hormone values among rabbit groups except for progesterone that was higher during pregnancy in comparison to the other 2 status.
It could be concluded that rabbit does adjust their internal homeostasis during pregnancy and suckling. In addition, there is a positive correlation between some of the studied parameters indicating healthy status of the experimental does.

This study, glutathione (GSH) was used as feed supplements to ameliorate the deleterious effect of aflatoxin B1 (AFB1) on egg quality, semen quality, fertility and hatchability, immune response to Newcastle disease virus ( NDV), and AFB1 residual in fresh meat , liver and egg yolk. A total number of 120 Inshas laying hens ( Egyptian native strain) plus 24 cockerels from strain of 28 weeks of age were randomly distributed into 4 groups with 3 replicates each (10 hens + 1 cockeral). The remaining 12 cocks were also divided into four groups of 3 cocks each and reared separately for semen evaluation. The treatments were follow. 1: was the control basal diet which save all nutrients requirements of Inshas strain (control) ; 2: birds fed on control diet supplemented with ( 0.5 mg glutathion / kg diet, GSH); 3: birds fed on control diet contaminated with 1000 ppb of aflatoxin B1/ kg diet,AFB1, 4: birds fed on AFB1diet and supplemented with 0.5 mg glutathione / kg diet, AFB1+ GSH . The obtained results showed that feeding AFB1 diet significantly decreased egg shell weight%, egg shell-thickness, fertility, hatchability, moreover, the relative weights of liver, spleen, kidney and gizzard were significantly increased. In addition, emboryonic mortality percent was increased while, the overall semen quality measurements were depressed. Also AFB1 diet icreased the oxidative stress including depression of activities of antioxidant enzymes (GSH-Px, SOD and CAT) and increase MDA concentration in spleen extract. Addition of glutathione to AFB1 diet could make significant improvements of most of measurements including egg quality, semen quality, fertility, antioxidant status, immune status against NDV. Generally it could be recommend adding glutathione to decrease some of the adverse effects of aflatoxin B1on Inshas developed chicken strain

The aim of the study was to investigate the effect of feeding Japanese quail chicks on diets supplemented with different levels of germinated Moringa Oleifera seed (GMOS) on productive performance, carcass characteristics and blood constituents. A total number of 252 unsexed seven days-old Japanese quail chicks were randomly distributed to 4 equal groups each containing 63 chicks in 3 replicates with 21 chicks each. Four experimental diets supplemented with GMOS were formulated as follows: 0% (control), 0.25% , 0.50% and 0.75% GMOS for 7- 42 days.
The results showed that, birds fed GMOS at levels 0.75% followed by 0.50% had significantly higher body weight and body weight gain than birds fed the control diet. The feed consumption showed no difference in all treatments. The best feed conversion ratio and European Production Efficiency Index (EPEI) obtained by using 0.75% GMOS compared to control group. Abdominal fat significantly decreased by feeding levels 0.25, 0.50, and 0.75% GMOS respectively compared to the control group. Birds fed on GMOS significantly increased bursa percentages by using all levels of GMOS compared to control group. Plasma ALT decreased by using 0.75% GMOS compared to control. However, AST decreased in all levels of GMOS with no difference compared to the control. Plasma cholesterol had lower level in all treatments compared to control group. In addition, HDL fraction was increased and LDL fraction was decreased in all treatments of GMOS. Total antioxidant capacity was significantly increased in group fed 0.50% GMOS compared to other treatments. It could by conclude that using GMOS (0.25, 0.50 and 0.75%) improved performance, immune organs and blood constituents. The best level occurred by 0.75% GMOS in Japanese quails diets during the growing period (1-42 day).

A total number (15000 females + 1500 males) of Arbor ACRES strain broiler breeder at 54 wks old were used to study the effects of exogenous enzyme preparation (phytabex plus) on the productive performance, egg components, egg chemical composition, egg shell quality, fertility and hatchability. Birds were divided randomly into 3 treatments (broiler breeder basal diet supplemented with 0, 100g and 200g/ton with phytabex plus) and housed on deep litter at open house system under commercial conditions. Each treatment replicated 4 times. The results showed no significant differences among dietary treatments on productive performance including (body weight gain, egg production, egg weight, egg mass, feed consumption and feed conversion ratio), egg components and chemical composition and egg shell quality. In addition, birds fed diet supplemented with 200 g/ton phytabex plus recorded higher fertility and hatchability percentages during experimental period (20 wks) than other treatments (p<0.05). It could be concluded from this study that supplementation of 200 g / ton phytabex plus is recommended for enhancement of the fertility and hatchability percentages of broiler breeding.

EFFECT OF SUPPLEMENTING DIET WITH SODIUM BENTONITE AND/OR ORGANIC CHROMIUM ON PRODUCTIVE, PHYSIOLOGICAL PERFORMANCE AND IMMUNE RESPONSE IN MATROUH CHICKENS STRAIN. 2- DURING LAYING PERIOD.
The main objective of this study was to investigate the effect of sodium bentonite (Na-B) (0, 5 and 10 g/kg diet) and chromium picolinate (CrPic) (0,800 and 1200 µg/Cr /kg diet) in the diet on chicken productive and reproductive traits, some blood serum constitute, egg quality as well as the immune response. in this experiment 270 laying hens and 54 cocks of Matrouh local strain at 28 weeks of age were randomly distributed into 9 treatment groups (30 hens + 6 cocks / each treatment) in a factorial arrangement (3x3). Chicken fed diets were contaminated with Aflatoxin (AFB1),7.55 µg/kg dry matter (DM) during the laying period.
Rations with Na-B significantly (P≤0.05 or P≤0.01) improved body weight changes (BWC), egg weight, egg production and egg mass during the period from 28-40 wks of age. As well as, Haugh units, serum calcium and glutathione peroxidase (GPX) at 40 Wks of age. Likewise, results of cocks revealed improvement blood testosterone value, percentages of sperm motility and sperm cell concentration, fertility eggs % and hatchability/total eggs. Na-B supplementation significantly (P≤0.05 or P≤0.01) decreased feed intake, serum cholesterol, malonidialdehyde (MDA) values, dead spermatozoa (%) and seminal MDA.
CrPic supplementation diet significantly (P≤0.05 or P≤0.01) increased BWC, egg weight, production rate, egg mass, yolk index, Haugh unit, thickness of egg shell, albumen percentage, the titer of sheep red blood cells (SRBCs), serum total protein, albumin, insulin and Ca concentrations. CrPic improved blood testosterone, physical semen properties and seminal MDA. However, significant decreased yolk weight percentage and serum cholesterol.
Moreover, egg weight and egg mass, yolk index and Haugh unit, SRBCs concentrations, and blood testosterone of cocks, sperm motility, dead spermatozoa and sperm cell concentration, values of fertility eggs % and hatchability/fertile eggs (%) were significantly influenced by the interaction between dietary Na-B and CrPic.
It is clear that, supplementing the chicken diet with both 10 g Na-B and 1200 µg CrPic /kg diet alone or together is recommended for improving most of productive traits, including egg and semen quality, fertility and hatchability and serum biochemical traits as well as improved immune responses.

A total of 780 unsexed day old Arbor Acres chicks were used. The birds were randomly distributed into 26 treatments of 30 chicks each. Two studies were designed to compare three phytase sources differed in their microbial origin and thermo-stability on performance and bone mineralization of broilers. In Exp. 1, with less 40% available phosphorus (aP) diets than recommendation, chicks were fed 0.3% and 0.27% aP (-40% aP), during starter and grower periods, respectively, and supplemented with one of the following phytases; Phytase I (Schizosaccharomyces pombe), Phytase II (Trichoderma reesei) and Phytase III (Pichia pastoris) at 3 levels (0, 500 or 750 FTU/kg diet) each within two feed forms (mash or pellet) in 3×3×2 factorial design. In a concurrent study, with less 20 or 40% aP with the most stable phytase source from Exp. 1 at 0, 500 and 750 FTU/kg diet, also in mash or pellet feeds (Exp. 2) in 2×3×2 factorial arrangement. In both experiments, two control groups fed strain recommendation of aP (contained 0.5%, 0.45% aP during starter and grower periods, respectively) with the same feed forms were used for comparison. Results obtained indicate that:
Experiment 1: There is a difference in thermo-stability among phytase sources according to the microbial origin.
1- Chicks fed -40% aP and supplemented with either Phytase I or Phytase III had significantly higher weight gain and carcass percentage than Phytase II.
2- Chicks fed pellet diets recor ded (P≤0.05) better growth performance compared to those on mash diets.
It could be concluded that: phytase I (Schizosaccharomyces pombe ) is the most stable phytase, while, chicks fed -40% aP, irrespective of phytase source didn't reach the values of control group (strain recommendation of aP) concerning growth performance parameters or bone measurements.
Experiment 2: Chicks fed -20% aP diet improved feed conversion ratio (FCR) by 4.1% for overall period and higher plasma P and Ca by 34.8% and 27.7%, respectively comparing to others fed -40% aP.
1- Chicks fed dietary Phytase I at levels of 500 and 750 FTU/kg diet improved significantly live body weight, carcass % and better overall FCR.
2- By feeding pellet diet, chicks recorded better overall FCR by 4.1% than those fed mash diet. It could be recommended that addition of coated Phytase I (Schizosaccharomyces pombe) at 500 FTU/kg diet to -20% aP diet improved growth, bone mineralization of broiler chicks fed either mash or pellet diets.

An experiment was conducted to evaluate dried potato waste (PWM) as energy source in broiler diets into diets by its incorporating of two strains of broiler chicks (Arbor Acers and Hubbard F15) instead of Yellow corn. The productive performance, carcass characteristics with some external and internal organs, meat quality and economic efficiency of the experimental diets were observed. A number of 504 unsexed 14-days old broiler chicks, fifty-fifty between Arbor Acers and Hubbard F15, were randomly distributed into six equal experimental groups for each strain, respectively. Each experimental group comprised of 42 chicks which divided into 3 replicates of 14 chicks each. Grower and finisher diets were formulated to investigate the effect of replacing potato waste meal by yellow corn using levels of 0, 25 and 50% with and without commercial enzymes in (2 × 3 × 2) factorial experimental, respectively during growth (15-28) and finishing (29-42) periods. Feed and water were offered ad-libitum during the studied experimental growth periods. From economical point results of view, it is advisable to use PWM up to 25% to replace a part of yellow corn in broiler diets supplemented with commercial enzymes mixture during grower and finisher periods. Such practice helps in improving the profitability without any adverse effects on productive performance, carcass traits of broiler chicks.
