复合益生菌对湖羊生长性能、血清生化指标和屠宰性能的影响
Effects of compound probiotics on growth performance,serum biochemical indexes,and slaughter performance of Hu sheep
摘要
Abstract
The purpose of this experiment was to study the effects of compound probiotics on the growth performance,serum biochemical indexes,and slaughter performance of finishing Hu sheep.Eighty-four 3-month-old male Hu sheep with similar weight were randomly divided into four groups with three replicates in each group and seven sheep in each replicate.The control group was fed with basal diet,and the basal diet was supplemented with 0.1％,0.2％,and 0.3％compound probiotics(Bacillus subtilis,Bacillus licheniformis and Enterococcus faecalis)in experimental group Ⅰ,group Ⅱ,and group Ⅲ,respectively.The pre-test period was 15 days,and the formal test period was 120 days.The results showed that the average daily gain of experimental group Ⅲ was extremely higher than that of control group(P＜0.01),and the feed-to-weight ratio was extremely lower than that of experimental control group(P＜0.01).The IgA content in group Ⅲ was extremely higher than that in the control group(P＜0.01),while the other data in each experimental group showed no significant difference compared to the control group(P＞0.05).There was no significant difference in serum biochemical indexes,and serum antioxidant indexes between the experimental group and the control group(P＞0.05).The mutton pH value of experimental group Ⅰ and group Ⅲ was extremely lower than the other groups(P＜0.01).The contentrations of fat,saturated fatty acid,and unsaturated fatty acid in mutton of group m were extremely higher than those of other groups(P＜0.01),and the live weight before slaughter was significantly higher than that of control group(P＜0.05).The study indicates that adding compound probiotics to the diet can improve the growth performance,meat quality,and slaughter performance of Hu sheep,and the feeding effect is better when the addition amount is 0.3％.关键词
