酵母细胞壁多糖与铝硅酸盐复合物对猪生长性能、免疫指标及养分消化率的影响
Effects of Yeast Polysaccharide and Aluminosilicate Complex on Growth Performance, Immune Indices and Nutrient Digestibility of Pigs
摘要
Abstract
This experiment was conducted to explore the effects of yeast polysaccharide ( YP) and aluminosilicate complex (AC) on growth performance, immune indices and nutrient digestibility of pigs. One hundred and forty crossed pigs (Dueoc x Landrace x Yorshine) with an average body weight of (66. 18 ± 1. 26) kg were randomly assigned to 5 groups with 4 replicates per group and 7 pigs per replicate. Pigs were fed different experimental diets which contained different doses of admixture in 5 groups: group A (control group) did not contain the admixture; group B contained 0.1% YP; group C contained 0. 1% YP and 0. 9% AC; group D contained 0. 1% YP and 1. 9% AC; group E contained 0. 1% YP and 2. 9% AC. The experiment lasted for 51 days. The results showed as follows; 1) the average dietary gain in groups D, E was significantly lower than that in the control group (P <0. 05) , but there was no significant difference in average dietary feed intake and feed/gain among all groups (P >0. 05). 2) Compared with the control group, the levels of complement 3, immunoglobulin M, immunoglobulin A and glutathione peroxidase activity in serum were increased significantly (P <0. 05) , but there was no significant difference in superoxide dismutase activity and complement 4 level in serum. 3) There was no significant difference in nutrient digestibility among all groups ( P >0 05). In conclusion, adding YP and AC admixture in the diet can decrease growth performance, while adding 0. 1% YP and 1.9% AC in the diet can enhance immune function of growing pigs.
