摘　　要：[目的]探讨配方奶粉对哺乳仔猪的促生长作用。[方法]选取长大母猪初产20窝、经产28窝哺乳期仔猪分别设置对照组、试验组,对照组不饲喂配方奶粉,试验组饲喂配方奶粉,进行饲养对比试验。[结果]加饲奶粉液的初产、经产试验组哺乳仔猪断奶体重分别比对照组增加0.59、0.97 kg;平均日增重分别高20.84、51.00 g/d;试验组增重效果显著高于对照组;平均边际成本分别为11.76、10.67元/头。[结论]奶粉可以提升哺乳仔猪生长速度,但对奶粉喜好具有一定窝间和个体间差异,未观察到仔猪因采食奶粉表现肠道不适或引起腹泻的现象,哺乳期适宜的配方奶粉可以部分替代母乳。[Objectives]In order to explore the growth-promoting effect of formula on lactating piglets.[Methods]A total of 20 litters of lactating piglets born for the first time from grown sows and 28 litters of lactating piglets born from multiparous sows were selected as the control group and the experimental group,respectively.The control group was not fed with formula milk powder,and the experimental group was fed with formula milk powder to conduct a feeding comparison test.[Results]Compared with the control group,the weaning weight of lactating piglets born for the first time from sows and lactating piglets born from multiparous sows in the experimental groups with feeding milk powder liquid increased by 0.59 kg and 0.97 kg,and the average daily weight gain was 20.84 g/d and 51.00 g/d,respectively.The weight gain effect of the experimental group was significantly higher than the control group.The average marginal cost was 11.76 yuan for per pig and 10.67 yuan for per pig,respectively.[Conclusions]Milk powder could increase the growth rate of lactating piglets,but there were differences among different litters and individual differences in the preference of milk powder,and no intestinal discomfort or diarrhea was observed in piglets due to milk powder consumption,and milk formula can partially replace breast milk during lactation.
