Effects of Lactobacillus Microecologics on Growth Performance and Immunity of White Wing Pigeons
摘要
Abstract
The objective of this experiment was to study the effects of Lactobacillus microecologics on growth performance, immune organ indexes, serum immune globulin G ( IgG ) content and intestinal microflora of white wing pigeons. Sixty one-day-old white wing pigeons were randomly divided into 3 groups with 20 pi-geons per group. Group 1 was control group. Groups 2 and 3 were Lactobacillus microecologics groups, sup-plemented with 2×106 and 5×106 CFU/d, respectively. The pre-trial period lasted for 3 days, and the experi-ment lasted for 16 days. The result showed as follows: at the age of 19 days, compared to control group, the Lactobacillus microecologics groups with 2×106 and 5×106 CFU/d increased the final body weight by 8.29%and 15.10% ( P<0.05) , reduced the ratio of feed to gain by 6.36% and 8.66% ( P<0.05) , increased the ser-um IgG content by 10.09% and 17.98% (P<0.05), reduced the E.coli number by 4.27% and 9.26% (P<0.05), increased the Lactobacillus numbers by 5.41% and 9.71% (P<0.05), respectively. In comparison with the control group, the Lactobacillus microecologics groups with 5 × 106 CFU/d enhanced the indexes of bursal and thymus by 16.07% and 8.33% ( P<0.05) , respectively. In conclusion, Lactobacillus microecolog-ics can improve growth performance, and enhance the immune function. The optimal daily supplement for white wing pigeons was 5×106 CFU under this experimental condition.关键词
