低聚壳聚糖对母猪繁殖性能、泌乳性能和血浆生化指标的影响
Effects of Oligo-Chitosan on Reproduction Performance, Lactation Performance and Plasma Biochemical Parameters of Sows
摘要
Abstract
This study was conducted to investigate the effects of dietary oligo-chitosan on reproduction perform-ance, lactation performance and plasma biochemical parameters of sows.Twenty-four healthy female Yorkshire sows with similar parity, body weight and expected date of childbirth were assigned into 3 groups with 8 repli-cates per group and 1 sow per replicate.Sows in the control group were fed the basal diet, and the others in the experimental groups Ⅰ and Ⅱ were fed the basal diet supplemented with 50 and 100 g/t oligo-chitosan, re-spectively.The experiment lasted from the 85th day of pregnancy to the 21st day after delivery.The results showed as follows: 1 ) compared with the control group, dietary oligo-chitosan significantly increased the healthy piglets and average daily feed intake (ADFI) of lactation of sows (P<0.05), significantly decreased the born process time of sows ( P<0.05 ) , and improved constipation and decreased backfat thickness loss of sows to a certain extent.The birth litter weight of piglets in experimental groupⅠwas significantly higher than that in the control group ( P<0.05) , and the total milk yield during lactation of sows in experimental groupⅡwas significantly higher than that in the control group (P<0.05).2) Compared with the control group, the milk fat content in colostrum of sows in experimental groupsⅠandⅡwas significantly increased ( P<0.05) , and the contents of urea nitrogen ( UN) in colostrum and arginine, total amino acids and limiting amino acids in milk in experimental group Ⅰ were significantly increased ( P<0.05) .3) The activity of glutamic-pyruvic transaminase ( GPT) in plasma of sows in experimental groups Ⅰ and Ⅱ was significantly lower than that in the control group ( P<0.05), and the activities of alkaline phosphatase ( ALP) and lactate dehydrogenase ( LDH) and the contents of total protein ( TP) , albumin ( ALB) , UN, triglyceride ( TG) , total cholesterol ( CHO) , high-density lipoprotein ( HDL ) and low-density lipoprotein ( LDL ) in plasma had no significant differences among all groups ( P>0.05 ) .In conclusion, dietary oligo-chitosan can promote the reproduction performance and lactation performance of sows.According to the results of this study, the optimum dosage of oligo-chitosan in diet of sow is 50 g/t.关键词
