小肽對(duì)種公豬精液品質(zhì)的影響
[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.
