摘要
为研究复合微生态制剂对仔猪生长性能和养分表观消化率的影响,试验选取120头(60头雌性和60头雄性)28日龄断奶的三元杂交仔猪,称重后随机分为4组。对照组饲喂基础日粮,试验Ⅰ、Ⅱ、Ⅲ组在基础日粮中分别添加0.05%、0.1%、0.2%的复合微生态制剂,试验期30 d。试验结果显示:相比于对照组,试验Ⅱ、Ⅲ组仔猪平均末重分别增加9.3%、6.5%(P <0.05),平均日增重分别增加20.6%、14.7%(P <0.05),Ⅱ组料肉比降低11.3%(P <0.05)。试验Ⅱ组粗蛋白质的表观消化率较对照组提高9.6%(P <0.05),Ⅰ、Ⅱ、Ⅲ组粗纤维表观消化率较对照组分别提高19.0%、64.9%、35.3%(P <0.05),试验Ⅱ、Ⅲ组粗脂肪表观消化率较对照组分别提高10.5%、8.1%(P <0.05),Ⅱ组总钙表观消化率提高5.1%(P <0.05),其他指标差异不显著(P> 0.05)。综述,饲料中添加复合微生态制剂有助于仔猪的生长并能显著提高仔猪对营养物质的表观消化率,其中添加量为0.1%时效果较好。
The present study was carried out to evaluate the efficacy of compound probiotic on the growth performance and apparent digestibility of nutrients in piglets.One hundred and twenty 28 days old Duroc×Danish Landrace×Edelschwe piglets were divided into the control group and experimental groups I,II and III.Groups I,II and III were added on the basis of diet 0.05%,0.1%,0.2%probiotic respectively,the experiment period lasted for 30 days.The results showed that compared with the control group,the terminal weigh of groups II,III were increased by 9.3%,6.5%(P<0.05),and the average daily gain were increased by 20.6%and 14.7%(P<0.05).The feed conversation of group II was decreased by 11.3%(P<0.05).The apparent digestibility of crude protein in groupⅡwas increased by 9.6%(P<0.05),in addition,the apparent digestibility of crude fat in groups II,III were increased by 10.5%,8.1%(P<0.05).It could be seen that the addition of compound probiotic to the diet could improve the growth performance and the apparent digestibility of nutrients in piglets,the effect was better when the addition amount was 0.1%.
