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

Effects of Aromatic,Sweetener and Flavor Enhancer Compound Feeding Attractant on Growth Performance,Serum Biochemical Indices,Nutrient Apparent Digestibility and Faecal Microflora of Weaning Piglets

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(P<0.05);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(P>0.05)。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。

This study was conducted to investigate the effects of dietary different levels of aromatic, sweetener and flavor enhancer compound feeding attractant （ASF-CFA） on growth performance, serum biochemical indi- ces, nutrient apparent digestibility and faecal microflora of weaning piglets. Seventy two （43±4 ）-day-old healthy Large White piglets with similar body weight were selected and randomly divided into 3 groups with 3 replicates per group and 8 piglets per replicate. Piglets in the control group were fed a basal diet, and the others were fed the basal diets supplemented with 1 and 2 kg/t ASF-CFA, respectively. The trial lasted for 28 days. The results showed that compared with the control group, diet supplemented with 2 kg/t ASF-CFA significantly increased the average daily feed intake and average daily gain （P〈0.05） ; diet ASF-CFA had no influences on serum biochemical indices, nutrient apparent digestibility and faecal microflora of weaning piglets （P〉0.05）. It is concluded that dietary supplemented with 2 kg/t ASF-CFA can increase the average daily feed intake and average daily gain, and then improve the growth performance of weaning piglets. Under the conditions of this experiment, the suitable supplemental level of ASF-CFA for weaning piglets is 2 kg/t.
