异亮氨酸对断奶仔猪睾丸生长发育、抗氧化能力和生殖激素水平的作用研究
Effects of isoleucine on testicular growth and development,antioxidant capacity,and reproductive hormone levels in weaned piglets
摘要
Abstract
The study aimed to investigate the effects of different levels of isoleucine in the diet on the testicular growth and development,antioxidant function,and reproductive hormone levels in weaned piglets.A total of 18 weaned piglets at the age of 28 days were randomly divided into three groups with six replicates per group and one piglet per replicate.The dietary isoleucine levels in all groups were 0.8%,1.0%,and 1.2%,respectively.The trial period was 21 days.The results showed that compared with 0.8%isoleucine group(control group),testis size and weight in 1.0%isoleucine group were significantly increased(P<0.05),the cross-sectional area and circumferential length of convoluted seminiferous tubule in 1.0%and 1.2%isoleucine groups were significantly increased(P<0.05).The activity of glutathione peroxidase(GSH-Px)in testicular tissue of 1.0%isoleucine group was significantly increased(P<0.05),and the content of malondialdehyde(MDA)was significantly decreased(P<0.05).The 1.0%isoleucine group had significant regulation on the reproductive related indexes of hypothalamic-pituitary-testicular gonad axis.The results show that 1.0%isoleucine can alleviate oxidative stress caused by weanling of piglets,and affect the morphology and reproductive indexes of the testis of piglets by changing the level of reproductive hormone secretion in the gonadal axis of hypothalamic-pituitary-testicular tissue.关键词
