【摘要】：本试验旨在研究饲粮中添加不同水平香甜鲜复合诱食剂对断奶仔猪生长性能、血清生化指标、养分表观消化率和粪便微生物菌群的影响。选取(43±4)日龄体重相近的健康大白仔猪72头,随机分为3个组,每组3个重复,每个重复8头猪。对照组饲喂基础饲粮,试验组分别在基础饲粮中添加1和2 kg/t的香甜鲜复合诱食剂。试验期28 d。结果表明:与对照组相比,饲粮中添加2 kg/t香甜鲜复合诱食剂能够显著提高断奶仔猪平均日采食量和平均日增重(P0.05);饲粮中添加香甜鲜复合诱食剂对养分表观消化率、血清生化指标和粪便微生物菌群的影响不显著(P0.05)。由此可见,饲粮中添加2 kg/t香甜鲜复合诱食剂能提高断奶仔猪平均日采食量和平均日增重,提高生长性能。本试验条件下推荐断奶仔猪饲粮中添加2 kg/t香甜鲜复合诱食剂为宜。
[Abstract]:The purpose of this experiment was to study the effects of different levels of sweet and fresh compound food inducer on growth performance, serum biochemical index, apparent nutrient digestibility and fecal microbial flora of weaned piglets. Seventy-two healthy white piglets of similar body weight were randomly divided into 3 groups with 3 replicates in each group and 8 pigs in each group. The control group was fed with basic diet, and the experimental group was fed with 1 and 2 kg/t of sweet and fresh compound food attractant respectively. The trial period was 28 days. The results showed that compared with the control group, the average daily intake and average daily gain of weaned piglets were significantly increased by adding 2 kg/t sweet and fresh compound attractant to diet, and the apparent digestibility of nutrients was significantly increased by adding sweet and fresh compound food attractant to diet. The effects of serum biochemical indexes and fecal microbial flora were not significant (P 0.05). It can be seen that adding 2 kg/t sweet and fresh compound attractant to diet can increase the average daily feed intake and average daily gain of weaned piglets and improve the growth performance of weaned piglets. Under the experimental conditions, it was recommended that 2 kg/t sweet and fresh compound attractant should be added to the diet of weaning piglets.
