Abstract

This study was conducted to determine the effect of Amino acid Methionine and Lysine on the reproductive performance of male Awassi sheep. Twenty Awassi males aged range 10-12 months and average weight 32± 0.5kg were used in this study, during the period from May to August 2022. The animals were randomly divided into four equal groups. The first group was the control group (T1). In this group, sheep were fed on standard diet without any additive. The second treated group (T2) were fed on standard diet supplemented with coated Methionine (1.5g/sheep/day). The third treated group (T3) were fed on standard diet supplemented with coated Lysine (2.5g/sheep/day). The fourth treated group (T4) were fed on standard diet supplemented with coated Methionine and Lysine at the same doses used in T2 and T3 .The results showed that there was a significant improvement (P≤0.05) in sperm characteristics of T4 as compared to other groups. T4 also showed the highest testosterone levels as compared with the other groups.T4group also showed a well development in the seminiferous tubules, Sertoli cells and Leydig cells as compared withT1.T4 showed the best histological testicular architecture especially Sertoli cells as compared with T1,T2andT3. It was concluded from this study that coated Methionine and Lysine might improve semen characteristics, testosterone levels and male reproductive performance in Awassi male.
包被蛋氨酸和赖氨酸及其组合对阿瓦西公羊育性的影响
本试验旨在研究氨基酸蛋氨酸和赖氨酸对阿瓦西公羊繁殖性能的影响。研究时间为2022年5 - 8月,选取10-12月龄雄性阿瓦西犬20只,平均体重32±0.5kg。这些动物被随机分成四组。第一组为对照组(T1)。本组饲喂标准日粮,不添加任何添加剂。第二处理组(T2)饲喂在标准饲粮中添加包膜蛋氨酸(1.5g/只/d)的试验饲粮。第三处理组(T3)饲喂在标准饲粮中添加包被赖氨酸(2.5g/只/d)的试验饲粮。第四处理组(T4)在标准饲粮中添加与T2和T3相同剂量的包膜蛋氨酸和赖氨酸。结果表明,与其他组相比,T4组的精子特征有显著改善(P≤0.05)。与其他组相比,T4组的睾丸激素水平也最高。与t1组相比,t4组的精小管、支持细胞和间质细胞发育良好。与T1、t2和t3相比,T4表现出最好的睾丸组织学结构,尤其是支持细胞。由此可见,包被蛋氨酸和赖氨酸可改善阿瓦西雄性精液特征、睾酮水平和雄性生殖性能。
