复合微生态制剂对肉兔生长性能、屠宰性能、 血清生化指标和抗氧化功能的影响.

The aim of this experiment was to study the effects of compound microecological preparations on growth performance, slaughter performance, serum biochemical indexes and antioxidant function of meat rabbits. A total of 120 30-day-old New Zealand rabbits were randomly divided into 4 groups. The control group was fed the basal diet, and the three experimental groups were fed the basal diet supplemented with 0.20%, 0.40% and 0.60% of the compound microecological preparation, respectively. The results showed that, compared with the control group, the addition of 0.60% of the compound microecological preparation to the diet significantly increased the weight at the end of the test period and the average daily weight gain of the rabbits (P<0.05), and significantly reduced the feed-to-weight ratio of the rabbits during the test period (P<0.05); the addition of 0.60% of the compound microecological preparation to the diet significantly increased the live weight before slaughter, half-eviscerated weight, eviscerated weight of the rabbits (P<0.05); the addition of 0.60% of the compound microecological preparation to the diet significantly increased the level of glutathione peroxidase activity in the se‐ rum of the rabbits (P<0.05). In conclusion, the application of 0.60% dose of compound microecological preparation in the diet can effectively improve the growth performance and slaughter performance of meat rabbits, and increase the activity of antioxidant enzymes in the serum of meat rabbits and improve the antioxidant capacity of the rabbit.
