大豆蛋白肽对断奶仔猪生长性能的影响

以断奶仔猪为实验动物,研究大豆蛋白肽对幼龄动物生长的影响功能。160头断奶仔猪随机分为4组,Ⅰ组为基础日粮添加3.0%血浆蛋白粉,Ⅱ组为基础日粮添加3.0%乐能小肽和3.0%血浆蛋白粉,Ⅲ组为基础日粮添加3.0%乐能小肽,Ⅳ组为基础日粮添加5.0%乐能小肽组,试验期12 d。试验结果显示,仔猪断奶后1~6 d、7~12 d或1~12 d,试验Ⅱ组和Ⅲ组均显著提高断奶仔猪生长性能（P〈0.05）,并显著提高断奶仔猪的饲料转化率（P〈0.05）。考虑到饲料成本,建议在断奶仔猪日粮中添加3.0%大豆蛋白肽。

Effect of Soybean Protein Peptide on Growth Performance of Weaned Piglets

This study was conducted to investigate the effect of soybean protein peptide on the growth performance of young animals by using weaned piglets as experimental animal. A total of 160 weaned piglets were included in this study and were randomly divided into four groups. Group I fed basal diet adding 3.0% plasma protein powder; Group Ⅱ fed basal diet adding 3.0% ＂Leneng＂, a commercial production of soybean protein peptide, and 3.0% plasma protein powder; Group Ⅲ fed basal diet adding 3.0%＂Leneng＂; Group Ⅳ fed basal diet adding 5.0%＂Leneng＂. The entire test period lasted for 12 d. The results showed that during 1-6 d, 7-12 d or 1-12 d after weaning, the growth performance of the piglets in groups Ⅱ and group m were both significantly increased （P〈0.05）, and the significant increase in feed conversion rate of the piglets was also observed （P〈0.05）. In view of the cost of feeding, 3% soybean protein peptide was commended to use for weaned piglets.
