Center, Minist. of Agric., Dokki, Giza, EgyptJournal Article20191016<strong>The objective of the present study was to evaluate the effect of dietary</strong>Anta<sup>®</sup>Ox FlavoSyn (as a wide source of natural Proanthocyanidins) <strong>on growth performance, carcass characteristics, blood constituents, </strong>and economic efficiency<strong> of </strong>local Domyati ducklings for 7 weeks<strong>. A total of 240 </strong>ducklings<strong> (8 weeks of age) was </strong>distributed into 4 groups with 6 equal replicates (10 ducklings/each replicate). The first group was fed the control basal diet (BD, 0.0 mg Anta<sup>®</sup>Ox FlavoSyn/kg diet) while, others fed 100, 150 and 200 mg Anta<sup>®</sup>Ox FlavoSyn/kg diet. The obtained results illustrated that ducklings fed 100 and 150 mg Anta<sup>®</sup>Ox FlavoSyn/kg diet displayed significantly (P ≤ 0.05) higher body weight gain, and performance index, lower feed consumption, and better feed conversion ratio than those fed the high level 200 mg/kg diet or those fed free-Anta<sup>®</sup>Ox FlavoSyn BD (control group) at different experimental periods. Ducklings fed different levels of Anta<sup>®</sup>Ox FlavoSyn had significantly improved carcass traits, hematological, and serum biochemical parameters, total antioxidant capacity, and economic efficiency compared to the control group. Consequently, it could be concluded that the usefulness of Anta<sup>®</sup>Ox FlavoSyn as a promising feed additive for enhancing the productive performance, health status, physiological responses <strong>of </strong>Domyati ducklings. Owing to its low price and the high natural antioxidant properties of the tested material can be used economically in diets of growing local Domyati ducklings, especially at levels of 100 and 150 mg/kg diet.<br /> Mansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364210920190901Effect of Mash and Pellet Diets with Different Levels of Protein and Energy on Broiler Performance in Finisher Period2792835480210.21608/jappmu.2019.54802ENHersh Abdulazal FarajAnimal Science Department, College of Agricultural Science Engineering, University of Sulaimani, IraqSaman Abdulmajid RashidAnimal Science Department, College of Agricultural Science Engineering, University of Sulaimani, IraqJournal Article20190901This study was investigating to examine the effect of mash and pellet diets with normal and low protein and energy levels on broilers performance in finisher period. four hundred eighty unsexed broiler chicks fed two type of (mash and pellet) diet, two protein levels (21% and 19% CP), and two energy levels (3200 and 3000 Kcal/Kg ME) in period 24 to 42 days of age. The weight gain, feed intake, feed per gain, and mortality were examined during the experimental periods (24 -42 d). after sloughed traits were measured at the end of the study (42 days) including gizzard percentage, dressing percentage, abdominal fat percentage and small intestine and their parts percentage.

The fingerlings were adapted for 3 weeks and then reared in triplicate groups in 15 tanks (n = 4 fish per tank with average initial weights of (40 ± 3.00 gm). The fish fed on experimental diets containing different levels of fructo-oligosaccharide (FOS); (0, 2.5, 5, 7.5, 10 gm FOS /kg diet) for apparent satiation twice a day for 10 weeks. Results showed that final weight, weight gain, daily growth rate, relative growth rate, and specific growth rate were significantly (<em>P</em><0.05) increased with 10 gm FOS /kg diet compared to the other groups. While, food efficiency ratio and protein efficiency ratio were significantly higher (<em>P</em><0.05) especially in group fed 10 gm FOS /kg diet (1.13 and 295.16) respectively compared to the other treated and control group. However, food conversion ratio in 0 gm FOS /kg diet (control) group was higher significantly (<em>P</em><0.05) among other groups (1.63).Mansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364210920190901Effect of In-Ovo Injection of Ascorbic, Folic Acids and their Combination on Hachability and Subsequent Growth Performance of Broiler Chicks2892955481310.21608/jappmu.2019.54813ENF.

El –GayarFac. of Agric., Mansoura Univ., EgyptJournal Article20190906A total number of 1260 fertile eggs were randomly divided into seven treatments (180 eggs/treatments with three replicates for each) to investigate the effect of in ovo-injection of ascorbic, folic and their combination at 14<sup>th</sup> day of incubation on hatchability and subsequent broiler growth performance from 1 to 28 day post-hatch. The fertile eggs were allotted to a completely randomized experimental design with seven treatments as follow: 1- The control group, eggs were without injection.2- The second group, eggs were injected with 0.1ml distiller water/ egg. 3- The third group, eggs were injected with 0.1ml solution 6 µg ascorbic acid (AA) /egg. 4- The fourth group, eggs were injected with 0.1ml solution containing 75 µg folic acid (FA) /egg. 5- The fifth group, eggs were injected with 0.1ml solution containing 150 µg FA /egg. 6- The six group, eggs were injected with 0.1ml solution containing 6 µg AA + 75µg FA/egg. 7- The seven group, eggs were injected with 0.1ml solution containing 6 µg AA+150µg FA /egg. The results indicated that hatchability of fertile eggs % was improved due to injection of 6 µg AA/egg and with combination between 6 µg AA and 150 µg FA/egg by about 9.97 and 3.71% respectively as compared to the control group. In respect of subsequent effect after hatch, the results revealed that in ovo injection treatments with AA<sub>6</sub>, FA<sub>75</sub>, FA<sub>150</sub> and AA<sub>6</sub>+FA<sub>75</sub> recorded the best value of live body weight compared to the control group by about from 51.46 to 69.48 g/ bird at 28 days of age. Feed intake was insignificant increased as a result of all in-ovo injection treatments with exception feed intake of chicks from eggs injected with AA<sub>6.</sub> No significant influence due to in–ovo injected with AA, FA and their combination on FCR could be detected as compared to the control group. In ovo injection of AA, FA and their combination significantly decreased triglycerides (TG) levels in serum blood. Also, the level of HDL significantly improved due to in-ovo injected with AA6 and FA75. Therefor, it could be mentioned that in-ovo injection of 6µg AA/egg and 6µg AA+150µg FA/egg in broiler eggs at 14<sup>th</sup> day of incubation can be applied to improve the hatchability of fertile eggs and subsequent growth performance during the period from 1 to 28 day of age.

Number of 24 California bucks having 5.3-5.5 months of age and weighing 2316-2429 g were divided into four groups (n=6). Bucks in the control group were fed free commercial diet, while those in the 2<sup>nd</sup>, 3<sup>rd</sup> and 4<sup>th</sup> groups were fed the same diet with 2% SFO, 2% FSO, or 1% SFO+1% FSO, respectively. Growth parameters were determined during the experiment (16 wk). Serum lipid, testosterone and fatty acid profiles were determined.Results showed insignificant treatment effect on body weight, feed intake and weight gain during the experiment (0-16 wk).The differences in serum triglycerides and total lipids between treatment groups and control were not significant, but triglycerides increased (P<0.05) in FSO- than SFO-bucks. Phospholipids decreased (P<0.05) only by SFO+FSO, while total cholesterol and LDL increased (P<0.05) by SFO or SFO+FSO, but HDL was not affected. All oil types increased (P<0.05) Non-HDL, being higher (P<0.05) in SFO+FSO than in SFO or FSO. Serum Castelli I and II indices,AST and ALT activity, serum total fatty acids and fatty acid profile were not affected by treatment. In conclusion, balancing the ratio between n-6: n-3 fatty acids is important to be the easiest approach to indicate this would be intake of oils rich in n-3 or n-6 fatty acids, such as sunflower and flaxseed oils, respectively.<br /> Mansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364210920190901Synchronization of Estrus and Ovulation Using CIDR and Prostaglandin for Improving Pregnancy Rate of Repeat Breeder Egyptian Buffaloes3053125999510.21608/jappmu.2019.59995ENM.

Total of 20 cyclic lactating buffalo-cows (4-7 years, 400-500 kg, non-pregnant up to 90-postpartum day) and 10 cyclic buffalo-heifers (2.5-4 years, 350-400 kg, not conceived after 3 services) were used in this study. In the 1<sup>st</sup> group, a CIDR was inserted for 9 days, regardless reproductive status, and then animals were intramuscularly injected with PGF2α 24 h prior to CIDR removal. In the 2<sup>nd</sup> group, control animals were used at the same interval. Animals in heat were naturally served and blood samples were collected on different days post-service for serum P4 determination. Pregnancy was diagnosed on day 25 post-service. Results showed that overall mean of PR was higher (P<0.01), while serum P4 at estrus was lower (P<0.001) in CIDR than in control, but both parameters were not affected significantly by animal type or CIDR x animal type interaction. Serum P4 at estrus was lower (P<0.05) in pregnant than in non-pregnant, regardless treatment or animal type. At the following post-service days, serum P4 showed the same trend of change, being higher (P<0.001) in CIDR than in control animals and in pregnant than in non-pregnant animals, regardless animal type. It could be concluded that the random usage of CIDR device for 9 days and prostaglandin F2α injection 24 h pre-CIDR withdrawal can be applied to improve pregnancy rate of repeat breeder Egyptian buffaloes.<br />
