| 摘 要： | 试验旨在研究植物小肽对断奶仔猪生长性能、腹泻率及肠道发育的影响。选择体重为9.56 kg左右的35日龄健康杜长大三元杂种断奶仔猪120头,按照体重相似的原则随机分为2个处理,每个处理设6个重复,每个重复10头仔猪。对照组饲喂基础饲粮(含2.5%鱼粉),试验组添加2%植物小肽(替代基础饲粮中2.5%鱼粉)。试验期28 d。结果表明,植物小肽组仔猪日增重和日采食量分别比对照组提高5.88%(P<0.05)和2.67%(P<0.05),料重比显著降低2.74%(P<0.05)。与对照组相比,植物小肽组仔猪十二指肠和空肠的绒毛高度显著提高(P<0.05),十二指肠和空肠的隐窝深度显著降低(P<0.05),十二指肠和空肠的绒腺比(V/C)也显著提高(P<0.05)。综合来看,断奶仔猪饲粮中2%植物小肽替代2.5%鱼粉促进了仔猪肠道发育,提高了生长性能。

| Abstract: | The experiment was conducted to investigate the effects of plant peptides on growth performance,diarrhea rate and intestinal development of weaned piglets.A total of 120 piglets(DLY,9.56 kg)with 35 days weaned were randomly divided into two treatments according to the principle of similar weight,6 replicates per treatment and 10 piglets per replicate.The control group was fed with basic diet(containing 2.5%fish meal),and the experimental group was added with 2%plant peptide(replacing 2.5%fish meal in basic diet).The trial period lasted for 28 days.The results showed that the daily gain and feed intake of piglets in the plant peptide group were 5.88%and 2.67%higher than those in the control group,respectively(P<0.05),and the feed weight ratio was significantly reduced by 2.74%(P<0.05).The villus height of duodenum and jejunum,the crypt depth of duodenum and jejunum,and the ratio of of villus height to crypt depth(V/C)of duodenum and jejunum were significantly increased(P<0.05).In conclusion,2%plant peptides instead of 2.5%fish meal in weaned piglets'diets promoted intestinal development and improved growth performance. |
