不同饲喂方式对断奶仔猪生长性能和健康状况的影响

Effects of different feeding methods on growth performance and health status of weaned piglets

试验旨在研究液态和固态两种不同饲喂方式对断奶仔猪生长性能和健康状况的影响。将断奶后健康状况良好且体重较均一的360头“杜×长×大”三元仔猪随机分为对照组和试验组,每组5个重复,每个重复36头仔猪。对照组饲喂固态饲料,试验组饲喂水料比2.5∶1的液态料。试验期40 d。结果显示:试验组断奶仔猪的平均日增重较对照组提高了17.82%(P<0.05),平均日采食量提高了13.11%(P>0.05);成活率较对照组提高了1.41%,腹泻率降低了30.51%。试验第7 d时,试验组断奶仔猪腹泻率比对照组降低了16.64%;随着饲养日龄逐渐增加,两组的腹泻率均呈不同趋势逐步降低;试验第40 d时,试验组和对照组断奶仔猪的腹泻率分别为0.46%、1.16%。不同饲喂方式对断奶仔猪的毛况和肤色影响不显著(P>0.05),但具有一定的改善趋势。研究表明,液态饲喂对断奶仔猪的生长性能和健康状况均具有一定的改善作用。

The experiment aimed to investigate the impact of two different feeding methods,liquid and solid,on the growth performance and health status of weaned piglets.A total of 360 healthy and weight-uniform'Duroc×Landrace×Yorkshire'triple-cross weanling pigs were randomly divided into a control group and an experimental group,with five replicates per group and 36 pigs per replicate.The control group was fed solid feed,while the experimental group was fed liquid feed with a water-to-feed ratio of 2.5∶1.The trial lasted for 40 days.The results showed that the average daily weight gain of weaned piglets in the experimental group increased by 17.82%compared to the control group(P<0.05),and the average daily feed intake increased by 13.11%(P>0.05),the survival rate improved by 1.41%,and the diarrhea rate decreased by 30.51%.On the 7th day of the trial,the diarrhea rate of weaned piglets in the experimental group was reduced by 16.64%compared to the control group.As the breeding age increased,the diarrhea rates of both groups showed different trends and gradually decreased,on the 40th day of the trial,the diarrhea rates of weaned piglets in the experimental and control groups were 0.46%and 1.16%,respectively.The different feeding methods had no significant effect on the coat condition and skin color of weaned piglets(P>0.05),but there was a certain trend of improvement.The study indicates that liquid feeding has a certain improving effect on the growth performance and health status of weaned piglets.
