【摘要】：为了探讨小肽对种公猪精液品质、血液生化指标、免疫指标的影响,试验采用在日粮中添加不同剂量的小肽测定其对种公猪精液品质影响的方法,以赤金蛋白肽为试验材料,选用24头种公猪按品种、年龄、精液量等对等的原则,随机分为3个试验组,每个试验组设8个重复,每个重复1头种公猪。试验1组和试验2组日粮分别含1%、2%小肽,对照组不添加,各处理组营养水平一致,饲养试验为2个月。结果表明:小肽提高了种公猪精子活力,对采精量、精子密度、精子畸形率等没有影响。不同水平的小肽对种公猪血清总蛋白、白蛋白、球蛋白、白球比、血清尿素氮、免疫球蛋白G(IgG)、免疫球蛋白A(IgA)、免疫球蛋白M(IgM)等指标均无显著影响(P0.05),以种公猪日粮中添加1%小肽为宜。
[Abstract]:In order to study the effect of small peptide on semen quality, blood biochemical index and immune index of breeding boar, the method of adding different dosage of small peptide to diet was used to determine the effect of small peptide on semen quality of breeding boar. According to the principle of equivalence of breed, age and sperm volume, 24 boars were randomly divided into 3 experimental groups. Each trial group was divided into 8 duplicates and 1 reproducing boar. The diet of trial group 1 and group 2 contained 1% and 2% small peptides, respectively, while the control group did not add it. The nutrition level of each treatment group was the same, and the feeding experiment lasted for 2 months. The results showed that small peptide increased sperm motility of boar, but had no effect on sperm collection, sperm density, sperm deformity rate and so on. Different levels of small peptides against serum total protein, albumin, globulin, albumin / globulin ratio, serum urea nitrogen, immunoglobulin G (IgG), immunoglobulin A (IgA), There was no significant difference in immunoglobulin M (IgM) and other indexes (P0.05). It was better to add 1% small peptide to the diet of male pigs.
