摘　　要：为研究湿拌料饲喂断奶仔猪对仔猪生长性能、腹泻率以及免疫能力的影响,试验选用240头育肥猪分4组进行,每组3个重复,每个重复20头猪。其中对照组使用干料进行饲喂,试验组使用自动粥料器将饲料与水混匀后进行饲喂,粥料器分别设置为水料比不同的3个组,3个试验组水料比分别为2∶1,4∶1和6∶1,各组的猪群均自由采食、自由饮水。试验结果显示,3个试验组仔猪平均日采食量、平均日增重均高于对照组,试验组的腹泻率也低于对照组,同时相关免疫指标显示,试验组的免疫蛋白含量高于对照组,说明湿拌料能够提高断奶仔猪的生长性能,降低腹泻率,提高免疫力,当使用水料比为4∶1时,试验效果最佳。因此得出结论,使用湿拌料能够有效地提高断奶仔猪的生产性能,提高猪场生产效益,且水料比为4:1时能取得最好的生产成绩。In order to identify the effects of liquid feedstuff on the growth performance,diarrhea rate and immunity of weaning piglets,240 sample piglets were used in the experiment.They divided into 4 groups,with 3 replicates in each group and 20 piglets per replicate.The control group was fed with dry feedstuff.The test groups were feed with the automatically prepared porridge,the dry feedstuff mixed with water at the ratios of 2∶1,4∶1,6∶1,respectively;and all the piglets ate and drank in a free manner.The results showed that the average daily feed intake and average daily gain of the piglets in the three experimental groups were higher than those in the control group;and the diarrhea rate in the experimental groups was lower than that in the control group.The relevant immune indexes showed that the immune protein content of the test groups was higher than that of the control group.It could be concluded that the use of liquid feedstuff effectively improved the growth performance of weaning piglets,enhancing the production efficiency of the farm,with the water-to-feed ratio is 4∶1 having the best effect.
