前花青素对断奶仔猪生长性能和血清抗氧化、免疫及生化指标的影响
Effects of Proanthocyanidins on Growth Performance, Serum Indices about Antioxidant, Immune and Biochemistry of Weaned Piglets
摘要
Abstract
This trial was conducted to investigate the effects of dietary proanthocyanidins on growth perform-ance and serum indices about antioxidant, immune and biochemistry of weaned piglets. A total of 120 weaned piglets with the age of 23 days were randomly assigned to 4 groups ( control group and experimental groupsⅠ,Ⅱ and Ⅲ) with 3 replicates each and 10 pigs in each replicate. Pigs in the control group were fed a basic diet and the others in experimental groups were fed diets supplemented with 50, 100 and 150 mg/kg proanthocyani-dins in the basal diet, respectively. The trial lasted for 30 days after 7 days adaption. The results showed as fol-lows:1) compared with the control group, the average daily gain of pigs in experimental groups Ⅰ and Ⅱwas significantly increased ( P<0.05 or P<0.01) , and the diarrhea rate of pigs in all experimental groups was extremely significantly decreased ( P<0.01) with the lowest value in experimental groupⅡ. 2) Compared with the control group, serum total antioxidant capacity in experimental groups was significantly increased ( P<0.05) , which in experimental group Ⅱ was significantly higher than that in experimental groups Ⅰ and Ⅲ( P<0.05) . Serum malonaldehyde content was significantly decreased and superoxide dismutase activity was significantly increased in all experimental groups compared with the control group ( P<0.05) , and there were no significant differences among three experimental groups in both indices (P>0.05). 3) Compared with the control group, serum contents of immunoglobulin G and complement 3 in experimental group Ⅱ were signifi-cantly increased ( P<0.05) , serum complement 4 content in all experimental groups was significantly increased ( P<0.05) with no significant differences among them ( P>0.05) . 4) Compared with the control group, serum contents of triglyceride and urea nitrogen were significantly decreased (P<0.05 or P<0.01), serum albumin content in experimental group Ⅱ was extremely significantly increased (P<0.01), and there were no signifi-cant differences among all groups in the other serum biochemical indices (P>0.05). In conclusion, dietary proanthocyanidins can increase daily gain, decrease diarrhea rate, promote serum antioxidant capacity and en-hance immunity of weaned piglets, and the optimal supplemental level is 100 mg/kg.关键词
