香甜鲜复合物和香甜复合物在断奶仔猪教槽料和保育料中配合使用的效果

Application Effects of Aromatic,Sweetener and Flavor Enhancer Compound Feeding Attractant and Sweetener and Flavor Enhancer Compound Feeding Attractant in Creep Diet and Conservation Diet of Weaned Piglets

本试验旨在研究香甜鲜复合物和香甜复合物在仔猪教槽料和保育料中配合使用对仔猪生长性能、血清生化指标及养分表观消化率的影响。选取体况良好、平均体重为(2. 24±0.42) kg的21窝7日龄哺乳仔猪,随机分为3个组(对照组、Ⅰ组、Ⅱ组),每组7个重复。教槽阶段,对照组饲喂基础教槽料、Ⅰ组饲喂基础教槽料+0.8 kg/t香甜复合物和Ⅱ组饲喂基础教槽料+2.0 kg/t香甜鲜复合物;保育阶段,对照组饲喂基础保育料,Ⅰ组饲喂基础保育料+0.8 kg/t香甜复合物,Ⅱ组饲喂基础保育料+0.8 kg/t香甜复合物,直至试验结束。试验期57 d。结果表明:1)在教槽阶段,与对照组相比,Ⅰ、Ⅱ组平均日增重和平均日采食量差异不显著(P>0.05);Ⅱ组粗脂肪表观消化率显著提高了8.31%(P<0.05)。2)在保育阶段,与对照组相比,Ⅰ、Ⅱ组平均日增重和平均日采食量差异不显著(P>0.05);Ⅱ组血清瘦素含量显著降低了17.27%(P<0.05),饥饿素含量显著升高了15.69%(P<0.05)。3)试验全期,Ⅱ组平均日增重较对照组显著提高了10.44%(P<0.05)。综上所述,添加香甜鲜复合物的教槽料更受仔猪喜爱,较对照组和香甜复合物组有更好的饲喂效果;香甜鲜复合物和香甜复合物在仔猪教槽阶段和保育阶段配合使用比单独使用香甜复合物效果好。

This study was conducted to investigate the effects of aromatic,sweetener and flavor enhancer compound feeding attractant(ASF-CFA)and sweetener and flavor enhancer compound feeding attractant(AS-CFA)on growth performance,serum biochemical indexes,nutrient apparent digestibility of weaned piglets.A total of 21 litters 7-day-old healthy piglets with body weight of(2.24±0.42)kg were used in this trial.These piglets were randomly divided into 3 groups(control group,Ⅰgroup,Ⅱgroup)with 7 replicates.Piglets in the 3 groups were fed a control creep diet,the control creep diet+0.8 kg/t AS-CFA and the control creep diet+2.0 kg/t ASF-CFA during creep stage,respectively.Then,those in the 3 groups were fed a control conservation diet,the control conservation diet+0.8 kg/t AS-CFA and the control conservation diet+0.8 kg/t AS-CFA during nursery stage,respectively,and till the end.The experiment lasted for 57 d.The results showed as follows:1)during the creep stage,groupsⅠandⅡhad no significant difference in average daily gain(ADG)and average daily feed intake(ADFI)compared with control group(P>0.05);ether extract apparent digestibility of groupⅡsignificantly increased by 8.31%(P<0.05).2)During the nursery stage,groupsⅠandⅡhad no significant difference in ADG and ADFI compared with control group(P>0.05);leptin and ghrelin contents in serum of groupⅡhad significant differences compared with control group(P<0.05),leptin content significantly reduced by 17.27%(P<0.05)and ghrelin content significantly increased by15.69%(P<0.05).3)During the whole stage,ADG of groupⅡsignificantly increased by 10.44%compared with the control group(P<0.05).It is concluded that during creep stage,diets with ASF-CFA is more popular with piglets and has better effect than the control diet and AS-CFA diet.The combination of ASF-CFA and AS-CFA is better than AS-CFA alone when used in piglets during creep stage and nursery stage.
