  The aim of this study was to investigate the effects of dietary supplementation of WHAT with omega-3, coenzyme Q10 (CoQ10), and the combination of both on semen quality, reproductive performance, and plasma variables in broiler breeder roosters. A total of 48 broiler breeder roosters (Hubbard F15, 49 weeks of age) were randomly assigned to one of four experimental diets: a control (Con; basal diet consisting of corn-soybean base), a Salomega (S; basal diet supplemented with 30 g of Salomega per kg of feed), a CoQ10 (Q; basal diet supplemented with 400 mg of CoQ10 per kg of feed), and a combination diet (CSQ; basal diet supplemented with 30 g of Salomega and 400 mg of CoQ10 per kg of feed). Salomega (Agritech Co. Ireland) contains 50% fat and about 10% total omega-3 fatty acids. Each treatment was replicated four times with three roosters in each. The results showed that dietary supplementation of CoQ10 increased sperm concentration, sperm motility, sperm plasma membrane integrity, seminal plasma total antioxidant capacity (TAC), and blood testosterone (P<0.05) in comparison to the Con groups, and the synergistic effects were observed in the basal diet supplemented with 30 g of Salomega and 400 mg of CoQ10 per kg of feed (CSQ groups) compared to Con groups (P<0.05). In addition, the CSQ supplementation reduced plasma levels of glucose and alanine aminotransferase (ALT) activity (P<0.05) in comparison to the Con groups. Roosters fed the CSQ supplementation had significantly higher fertility, hatchability of total eggs, and sperm penetration rates in comparison to the Con group (P<0.05). It can be concluded that the dietary combination of omega-3 and CoQ10 had a synergistic effect to improve the reproductive performance of aged broiler breeder roosters in comparison to separately dietary supplementation with omega-3 or CoQ10. تفاصيل المقالة

  To determine chemical composition as well as apparent metabolizable energy corrected to zero nitrogen balance (AMEn) estimates of Amaranth grain in adult roosters by regression method, firstly, a specie of Amaranthus hybridus chorostachys were cultivated in a farm pilot at agriculture research station (Khalat Poushan-Tabriz- East Azarbaijan- Iran). After harvesting, amaranth grain was sifted and milled. Finally, the chemical composition of amaranth grain produced in the Advanced Animal Nutrition Laboratory was analyzed. Adult roosters 96-week-old Leghorn in individual metabolic cages for nine daysused to determine AMEn content by the regression method. The basal diet was based on corn-soybean with 3200 kcal/kg metabolizable energy and 12% protein. Two experiments with raw amaranth grain (RAG) and processing amaranth grain (PAG), started separately using 40 leghorn roosters in the form of completely random by factorial method (2´5), that each experiment consisted oftwo levels of Rovabio multi-enzyme (0 and 0.055%) and five amaranth grain levels (0, 15, 30, 45, 60% of replacement or embedment of energizing part of the diet). Each experiment included four replicates that included one bird, it was subjected to biological experiments in metabolic cages by total excreta collection method. The obtained results of regression equations in adult roosters showed that AMEn content for raw amaranth without enzyme (RAG-e), raw amaranth with an enzyme (RAG+e), processed amaranth without enzyme (PAG-e), and processed amaranth with an enzyme (PAG+e) were 3250.24, 3433.18, 3242.18 and 3438.09 kcal/kg, respectively. The total results of this study showed that according to amaranth's adaptable and nutritious agricultural features, it can have a good potential in supplementation of poultry diets with enzymes for improving the energy and nutrition quality. تفاصيل المقالة

  Good semen quality plays a very important role in promoting poultry breeding programs; due to its antioxi-dant properties and role in fat metabolism, L-carnitine seems to be effective in improving semen quality. Therefore, this study was performed to evaluate the effect of dietary L-carnitine supplementation on the motility parameters and qualitative traits in semen Cobb breed roosters. A total of twenty roosters, 24 weeks-old Cobb roosters randomly assigned to four experimental groups. The experimental design was conducted in a completely randomized design with 4 experimental treatments (T1: 0, T2: 125, T3: 250, and T4: 500 mg L-carnitine per kg diet) with 5 replications and sampling twice (semen collection) with an in-terval of 14 days. The collected semen was immediately evaluated for motility parameters and sperm qual-ity traits. The results showed that there is no significant difference between the levels of 250 and 500 mg of L-carnitine in semen parameters, but there are significant differences with other groups (P≤0.05). Semen collection time did not affect sperm parameters (P≤0.05). In conclusion, the addition of L-carnitine at a rate of 250 mg/kg diet can improve motility parameters and sperm quality traits in the Cobb rooster. تفاصيل المقالة
