不同复合诱食剂在仔猪教槽料和保育料中配合应用效果研究

本试验旨在研究香甜鲜复合诱食剂和香甜复合物诱食剂配合使用对仔猪生长性能、血清生化指标、养分表观消化率及粪便微生物数量的影响。选取8窝7日龄的大白仔猪,随机分为2个组,每个组4个重复,2个组分别用基础教槽料(对照组)和添加2 kg/t香甜鲜复合诱食剂的试验教槽料进行教槽训练。21日龄断奶时饲喂3 d粥状料过度(采食量无统计)。然后,分别在2个组中选取28头体重相近、体况良好的24日龄仔猪,每个组4个重复,继续饲喂相应教槽料。仔猪37日龄时更换保育料,对照组仍为基础保育料,试验组在基础保育料基础上添加0.8 kg/t香甜复合诱食剂,直至试验结束。试验期59 d。结果表明:1)经过前期教槽训练,与对照组相比,教槽料中添加香甜鲜复合诱食剂能显著提高断奶仔猪的平均日采食量(P0.10),显著降低血清中胰高血糖素样肽-1的含量(P0.10)。2)在保育阶段,与对照组相比,保育料中添加香甜复合诱食剂能显著提高断奶仔猪的平均日采食量和平均日增重(P0.10)。综合分析,2种复合诱食剂在仔猪教槽料和保育料中配合应用可以提高仔猪的生长性能,对粪便微生物菌群和养分表观消化率没有影响。

Application Effects of Different Compound Feeding Attractant in Creep and Cradling Feed of Piglets

This study was conducted to investigate the effects of aromatic,sweetener and flavor enhancer compound feeding attractant (ASF-CFA) combination with sweetener and flavor enhancer compound feeding attractant (AS-CFA) on growth performance,serum biochemical indices,nutrient apparent availability and fecal microbe number of piglets.Eight litters 7-day-old healthy Large White piglets were randomly divided into 2 groups with 4 replicates per group,those two groups were trained with control diet (control group) and the test diet (added 2 kg/t ASF-CFA) to teach groove,feeding porridge-like material at weaning 21-day-old for three days (feed intake data were not summarized).In each group,when the piglets were 24-day-old,a total of 28 healthy piglets with similar weight were selected from 2 groups randomly divided into 4 replicates.When the piglets were 37-day-old,control group fed control cradling diet and trial group fed trial cradling diet (added 0.8 kg/t AS-CFA) till the end.The experiment lasted for 59 days.The results showed as follows:1) after the early creep training,compared with the control group,creep diet added with 2 kg/t ASF-CFA significantly increased average daily feed intake of weaned piglets (P＜0.10),and significantlu reduced the serum glucagonlikepeptide 1 (GLP-1) content (P＜0.10).2) In the nursery stage,cradling diet added with 0.8 kg/t AS-CFA significantly increased the average daily feed intake and average daily gain of weaned piglets (P＜0.10).It is concluded that ASF-CFA combination with AS-CFA in creep and cradling feed can increase the growth performance and have no effects on nutrient apparent availability and fecal microbe number of piglets.
