【摘要】 本文旨在研究猪饲粮中添加功能性诱食肽对猪只生长性能的影响。试验选取72头25±1日龄断奶仔猪(杜×长×大),按体重分成2个组,每个组6个重复,每个重复6头猪。对照组饲粮中添加100~150mg/kg的甜味剂,试验组添加120~300 mg/kg的功能性诱食肽。试验从仔猪断奶开始一直持续到出栏,试验分为五个阶段。结果表明:与对照组相比,添加功能性诱食肽组各个阶段的平均日采食量、平均日增重都有所提高,其中第一阶段和15~30 kg阶段生长性能效果最好,平均日增重分别提高13.71%、10.36%(P<0.05)。由此可见,在猪饲粮中添加诱食性功能肽可以提高猪只平均日采食量和平均日增重,改善生长性能。更多还原

【Abstract】 The study was conducted to investigate the effect of dietary feed attractant peptides on the growth performance of pigs. 72 weaned piglets(25±1days old, DLY) were allotted randomly to 2 treatment groups with 6replicates in each group and 6 pigs per replicate. Control group fed diet supplemented with sweetener(100-150 mg/kg),while experiment group supplemented with feed attractant peptides(120-300mg/kg). The experiment last from weaning to market. The breeding stage was divided into five periods. The result showed that, compared with control group, the average daily gain and average daily feed intake of experiment group were higher. In the first period and 15-30 kg period pigs of experiment group had the best growth performance, the average daily gain 13.71%, 10.36% higher than that of control group( P < 0.05),respectively. It was suggested that dietary supplemental feed attractant peptides could increase the average daily gain and average daily feed intake of pigs, and improve the growth performance.更多还原
