Effects of Soybean Isoflavone and Astragalus Polysaccharide on Production Performance, Serum Biochemical and Immune Indexes and Milk Composition of Lactating Sows
摘要
Abstract
This trial was conducted to investigate the effects of dietary soybean isoflavone ( SI) and Astragalus polysaccharide ( APS) levels on production performance, serum biochemical and immune indexes and milk composition of lactating sows. Using a single factor experiment design, seventy two healthy Yorkshire×Land⁃race ( 2 parities) with good condition and similar birthday age were randomly arranged into 4 groups with 6 replicates per group and 3 lactating sow per replicate. The proportion of SI and APS was 1∶5. The control group was fed a basal diet ( without SI and APS) , and three trial groups were fed the basal diet supplemented with 100, 200 and 300 mg/kg SI and APS mixture, respectively. The experiment lasted for 21 days. The results showed as follows:1) the average daily feed intake of lactating sows of 100 and 200 mg/kg level groups was significantly higher than that of control group ( P<0.05) , the 21 days milk yield of 200 mg/kg level group was significantly higher than that of control group ( P<0.05) . 2) The serum total protein content of 200 mg/kg lev⁃el group was significantly higher than that of control group ( P<0.05) , the serum urea nitrogen content of trial groups was significantly lower than that of control group ( P<0.05) , the serum glycerin trimyristate content of 100 and 200 mg/kg level groups was significantly lower than that of control group ( P<0.05) , the serum im⁃munoglobulin G and interleukin⁃2 contents of trial groups were significantly higher than those of control group ( P<0.05) , the serum immunoglobulin A content of 200 and 300 mg/kg level groups was significantly higher than that of control group ( P<0.05) . 3) The butterfat ratio and lactoprotein content of trial groups were signif⁃icantly higher than those of control group ( P<0.05); the lactose ratio of 300 mg/kg level group was signifi⁃cantly higher than that of the control group, 100 and 200 mg/kg level groups ( P<0.05) , and the lactose ratio of 100 and 200 mg/kg level groups was higher than that of the control group, but had no significant difference ( P>0.05) . In conclusion, dietary supplementation of SI and APS can improve production performance, serum biochemical and immune indexes and milk composition of lactating sows. In this experiment, the suitable sup⁃plemental level of SI and APS mixture is 200 mg/kg.关键词
