  A total number of 360 day old male Ross broiler chicks were randomly assigned into eight experimental treatment groups (45 each) to study the effect of incorporated 30% wheat bran (WB) in broiler diets and the possibility to improve the feeding value of WB when supplemented with some feed additives. In Treatment 1 birds received control diet and birds in treatment 2 received the basal wheat bran diet (WB-diet). Birds of treatment 3,4,5,6,7 and 8 received the WB-diet supplemented with 0.01% Xylam (E), E +1% Radish extract (RE), 1% Tomato extract (TE), 1%TE +1%RE, 1% Sodium Sulphate (SS) and 1% SS +1% TE. Results showed that there were insignificant differences in weight gain (WG) and feed conversion (FC) between birds fed control diet and WB-diet in all growth periods. In the finisher period, there were insignificant differences among all treatments in WG and FC. The feed additives used failed to improve performance of WB-diet group under the conditions of this study. The WB-diet without or with additives significantly decreased abdominal fat % compared to the control diet. Addition of TE+RE to WB-diet improved the digestibility of all nutrients. WB-diet alone or with E significantly increased plasma antioxidant capacity while it decreased total plasma cholesterol compared to the control diet. The addition of TE alone or with RE to WB-diet significantly increased the level of plasma calcium. The WB-diet alone or with either E+RE or TE significantly increased globulin level in plasma compared to the control diet. It could be concluded that not only 30% WB can be incorporate into broiler diets without adverse effect on performance but also it have a beneficial effect on plasma antioxidant capacity, phosphorus and globulin.

  From day one to day nine of embryonic development, no ossification centre was observed in the embryo. Small centres of ossification were seen on the 10th day at some locations like the cervical vertebrae, thoracic vertebrae, clavicle, coracoid, scapula, humerus, radius and ulna. Other areas with centres of ossification on this day included the ilium, pubis, femur and fibular. By day 12, these centres of ossification were very prominent at the points seen on day 10 and in addition, the Ischium had ossification centre. By day 13, ossification centres showed up in lumbosacral vertebrae, radius ulna, ulnacarpal and carpometacarpal joints, metatarsus, tibiotarsus, patella, first phalanx of digit ii and second phalanx of digit iii. Between days 15 and 16, additional ossification centres were observed at coccygeal vertebrae, digits ii, iii and iv of pectoral limb. By day 21, ossification centre appeared on the pygostyle and by days 23 and 24, the right and left clavicles had joined together although not properly fused.

  Two experiments were conducted to investigate the growth performance, carcass characteristics, organ weights, plasma proteins and fecal N excretion in broilers fed a 18% crude protein diet supplemented with Thymus vulgaris, Curcuma longa, citric acid, lactic acid or their combinations. In the first experiment, 98 broiler chicks were fed a control diet or a control diet with 0.2% Thyme (TH), 0.2% Curcuma longa (CL), 0.2% Citric acid (CIT), 0.2% TH + 0.2% CL, 0.2% TH + 0.2% CIT, 0.2% CL + 0.2% CIT. In the second experiment, 98 broiler chicks were fed a control diet with 0.2% TH, 0.2% lactic acid (LAC), 0.2% CIT, 0.2% TH + 0.2% LAC, 0.2% TH + 0.2% CIT, 0.1% LAC + 0.1% CIT. Addition of 0.2% TH, or TH + CIT increased weight gain in 21 day-old birds in experiment 1 (p<0.05). Addition of supplements did not produce any significant increase in day 42 body weight. No significant effect of supplements on carcass characteristics, feed conversion, plasma proteins or organ weights were observed except for liver which was higher in birds fed CIT (experiment 1) (p<0.05). No difference was observed in the total protein, albumen or globulin in the plasma. No difference was noticed between dietary treatments on the percentage of fecal Nitrogen (N), AME or Nitrogen retention (NR). Although not significant, the birds fed TH + CL excreted 12.9% less fecal N than Control birds. Similarly, the NR was 13.25% higher in TH + CL when compared with Control birds. Considering the role of low protein diets in reducing feed cost and fecal N excretion, further studies are needed to evaluate the role of plant extracts and organic acids and their optimal levels for broiler birds fed a low protein diet that are raised under suboptimal commercial conditions.

  An experiment was conducted with broiler chicks to study the possibility of improving the utilization of Dried Distillers Grains with Solubles (DDGS) in broiler diets. A total number of 150 day-old broiler chicks were randomly assigned to five groups received, diet containing 12% corn Dried Distillers Grains with Solubles (DDGS diet) without or with enzyme preparation (E), radish root extract (RRE, as source of peroxidase enzyme ) or E plus RRE, in addition to the control diet .The addition of RRE improved numerically Body Weight (BW) at 28 days and significantly at 42 days by 3.42 and 3.11%, respectively compared to birds fed DDGS diet alone. Enzyme preparation failed to improve performance for broiler fed DDGS diet. While using DDGS diet significantly decreased plasma antioxidants capacity by 56.11% compared to control birds, addition of RRE significantly increased it by 515% compared to the birds fed DDGS diet alone. There were insignificant differences between experimental treatments in plasma cholesterol, lipids or creatinine content. The addition of RRE increased plasma phosphorus by 65.93% compared to the birds fed DDGS diet alone while the later decreased it by 6.22% compared to control diet. The control birds recorded significantly higher values of plasma uric acid compared to other treatments. It was concluded that using RRE as a source of peroxidase enzyme is a suitable feed additive for improving the utilization of DDGS.

  An experiment was designed to study the effect of Curcuma longa (CL), Cuminum cyminum L(CC) alone or with sulphate ion on alleviating the heat stress effects compared to vitamin C. Three hundred and sixty, 21-day old unsexed chicks of slow growing El-Salam strain were randomly divided among 8 treatments (each of 3 replicates of 15 unsexed chicks each) and housed in floor pens. One group was kept under thermoneutral condition at 28±4oC and 55±3% Relative Humidity (RH) during 21-84 day of age and fed practical corn-soybean meal diet (control diet). The other seven groups were kept for three successive days weekly under heat stress at 38±1.4oC and 49±2% RH from 12.00 to 16.00 pm. Chicks in Heat Stress treatments (HS) were fed basal diet without additives or with 250 mg Ascorbic Acid (AA) /kg diet, 0.2% of Curcuma longa (CL),0.2% Cuminum cyminum L (CC), 0.5% anhydrous Sodium Sulphate (SS), 0.2% CL+0.5%SS and 0.2%CC+0.5%SS. Heat Stress decreased body weight gain, feed intake, feed conversion, carcass percentage, nitrogen retention, ash retention and plasma antioxidants capacity while increased respiration rate (RR) and rectal temperature (RT). The addition of CL, CC alone or with SS in the diet can recover the negative effect of HS on performance, nitrogen retention, ash retention and plasma antioxidants capacity. To some extent these additives recover the negative effect on RR and RT. The Cuminum cyminum L plus sulphate seemed to be the best additive under the condition of this study.

  Three hundred one day-old of unsexed Cobb broiler chicks were used in present study to examine the ability of Cuminum cyminum L (CC), Citric Acid (CA) or Sodium Sulphate (SS) either alone or in combination to increase nitrogen retention and utilization of the Low Protein Low Energy Diet (LPLE), containing 4% lower protein and 200 kcal/kg lower energy than control diets. At 42 days of age, LPLE diets decreased weight gain and degrade feed conversion by 23.24% and 19.47%, respectively compared to control diet. Besides, LPLE diet decreased daily nitrogen excretion by 25.92% compared to control diet. Supplementing LPLE diet with CC, CA and SS together improved weight gain, feed conversion and nitrogen retention percentage by 7.21, 6.16 and 16.69%, respectively. Compared to control diet, the combination of such feed additives succeeded in reducing daily nitrogen excretion by 64.81%. It can be conclude that the three additives used in present study work in synergy under low protein and low energy conditions. Further studies are needed to determine the optimum level of these additives mixture with different levels of protein and energy.

  This study examines the hypothesis that natural antioxidants can improve the performance of local laying hens in late egg production period (48-60 weeks) especially in presence of sulphate ion. A total number of 288 hens plus 36 cocks 48 weeks old from Inshas and Dokki 4 strains (144 hens and 18 cocks from each strain) were equally divided into 12 groups with 3 replicates (8 hens + 1 cocks each) and housed in wire cages. The experimental hens fed from 48 to 60 week of age the control diet without or with 0.25% Cuminum cyminum L (CC), 0.5% Anhydrous Sodium Sulphate (SS), SS + CC, 20 mg commercial Canthaxanthin/kg diet (CAN) and CAN + SS. Compared to control diet, addition of CC, SS, CC + SS, CAN or CAN + SS increased egg number and egg yolk color score. All feed additives used in this study increased calcium, phosphorus, total protein, albumin, globulin and total antioxidants capacity in plasma while decreased LDL, HDL, total cholesterol and total lipids in both plasma and egg yolk. Feed additives increased T3 and estrogen hormones compared to control diet. Feed additives tended to improve semen quality parameters, fertility and hatchability of total and fertile eggs. The combination of CAN and SS was the most successful additive under the condition of this study. Further studies are needed to elucidate the mechanism of protecting hen hormones from free radical attack at the late egg production period.
