摘要
本试验选取不同断奶日龄(28~32天,42~45天,49~52天)长白×梅山(F_1)杂交仔猪和不同体重阶段生长猪共194头,按窝别、性别和体重随机分成两组进行试验,以研究维吉尼霉素与金霉素配伍使用对不同断奶日龄仔猪和生长猪生产成绩的影响。结果表明:饲粮中添加维吉尼霉素+金霉素与添加金霉素相比,有显著促生长和提高饲料利用率的效果。同时,在生长猪体重的不同阶段,其效果不同,8~20kg 日增重改善9.77%,饲料利用效率改善10.42%;20~50kg 日增重改善5.83%,饲料利用效率改善5.9%;50~70kg 两组间生产成绩差异不显著。饲料中添加维吉尼霉素+金霉素能显著提高养猪生产效益。另外,在断奶仔猪饲粮中添加维吉尼霉素+金霉素有防治仔猪腹泻的效果。
We chose 194“Changbai * Meishan”(F1)crossbred piglets weaned at different times(28-32 days,42-45 days,49-52 days)and growing pigs of different weights for the experiment.Then we grouped them randomly into two groups according to their litter,sex and weight,in the hope of finding out the influence of mixing virginiamycin and aureomycin to the growth of piglets weaned at different times and growing pigs.Results have shown that,compared with adding aureomycin in feed,adding virginiamycin and aureomycin to feed can remarkably promote the growth and improve the absorption rate of feed.Meanwhile,the results differ in different periods of growth of the pigs,with pigs of 8-20 kg increasing 9.77% daily,and the absorption rate of feed increasing 10.42%;pigs of 20-50 kg increasing 5.8% daily,and the absorption rate of feed increasing 5.9%.Pigs of 50-70 kg between the two groups differ not very much.Adding virginiamycin and aureomycin to feed can greatly increase the product benefits.Meanwhile,laxation of the piglets can be cured by adding virginiamycin and aureomycin to feed.
