乳化脂肪粉对断奶仔猪生长性能的影响

试验旨在研究乳化脂肪粉对断奶仔猪生长性能的影响。选择21日龄的断奶仔猪,按体重相近原则随机分栏成为两个对照组(基础日粮)和一个试验组:试验组在基础日粮中添加20 kg/t的乳化脂肪粉,每个处理2个重复(♀和♂各一栏),每个重复15头,试验期为10 d。研究结果表明:试验组和对照组的平均日采食量分别为0.239 kg、0.257 kg和0.240 kg;平均日增重分别为0.144 kg、0.129 kg和0.131 kg;平均料肉比分别为1.66、1.99和1.80。试验组的平均日采食量和平均料肉比均比两个对照组的低,而试验组的平均日增重比两个对照组高。研究结果表明:在本次试验中,乳化脂肪粉可以增加断奶仔猪的日增重、降低料肉比、提高饲料利用率,乳化脂肪粉对断奶仔猪的生长性能可以产生正面影响。

Effect of dietary emulsification fat powder on the growth performance of the weaned pigs

The objective of this experiment was to investigate the effect of dietary emulsification fat powder on the growth performance of the weaned pigs.The experiment was taken at Yunnan Shennong Breeding Company in Weize village,Shilin county of Kunming.The animal(90 castrated hog,PIC Camborough♀ ×402♂)were randomly divided into 3 treatment groups when the pigs weaned at 21 d of age.There were 15 pigs in a pen,2 replicated pens in each treatment.The trial diet was the basal diet supplemented with emulsification fat powder 20 kg/t,the trial period is for 10 days.The result shows that the average daily feed intake of pigs from the experiment group is lower than that of pigs from two control groups'(0.239 kg,0.257 kg and 0.240 kg),and the average daily gain of pigs from the experiment group is higher than that of two control groups'(0.144 kg,0.129 kg and 0.131 kg).Therefore,the FCR of pigs in the treatment group is lower than that of control groups'(1.66,1.99 and 1.80).So,in this study,the emulsification fat powder can increase the weaned pigs' daily feed intake,ruduce the weaned pigs' FCR,raise the utilization rate of feed.The emulsification fat powder has positive effect on the weaned pigs.
