液态饲喂在育肥猪上的使用效果

Effects of liquid feeding on growth performance of finishing pigs

为研究饲料液态饲喂对育肥猪生长性能和经济效益的影响,试验选用体重为(82.93±3.35)kg的"杜×长×大"(Duroc×Landrace×Yorkshire)三元杂交猪300头,随机分为3组,每组5个重复,每个重复20头猪,试验期为31 d,对照组饲喂固体颗粒饲料,试验A组用对照组日粮加水饲喂,试验B组日粮由干料、过期酸奶、水按比例配制而成,干基营养水平与对照组相当。试验结果表明:相比对照组,试验A组的平均日增重、平均日采食量分别提高了6.9%和2.1%,料重比降低了4.3%,但两组之间差异不显著;试验B组的平均日增重与对照组相当,平均日采食量、料重比分别降低了6.3%(P<0.05)和6.4%(P>0.05);同时,饲喂液态料的两个试验组经济效益均有不同程度提高。

Experiment was conducted to evaluate the effect of liquid feeding on finishing pigs.300 pigs[Duroc×Landrace×Yorkshire;(82.93±3.35)kg body weight]were randomly allocated to the following three dietary treatments,control group(dry fed basal diet),experimental group A(liquid fed basal diet)and experimental group B(liquid fed diet with expired yoghurt),the nutrient level of dry base was similar to the control,each treatment with 5 replicates of 20 pigs each.The experiment was lasted for 31 days.The result showed that:compared with the control,the average daily gain,feed intake of experimental group A were increased by 6.9%,2.1%respectively,and feed to gain ratio was decreased by 4.3%,there was no significant difference between the two groups;the average daily gain of experimental group B was similar to the control,while the average daily intake,feed to gain ratio were decreased by 6.3%(P<0.05),6.4%(P>0.05).Also liquid feeding improved the economic benefits of the two experimental groups.
