日粮中添加不同水平酵母硒对猪生长性能的影响

Effects of Dietary Supplementation with Different Levels of Yeast Selenium on Growth Performance of Pigs

为研究日粮中添加酵母硒对育肥猪生长性能的影响。试验选用60头体重(80±1.0)kg杜长大育肥猪随机分为3个处理组,每组2个重复,每个重复10头猪,1组为对照组饲喂基础日粮,试验2、3组分别在基础日粮中添加50、100 mg/kg酵母硒,试验期50 d。在试验结束时测定育肥猪生长性能。结论:在基础日粮中添加100 mg/kg的酵母硒可以提高育肥猪的生长性能。

To study the effect of dietary yeast selenium on the growth performance of finishing pigs.(80±1.0)kg 60 du growing-finishing pigs were randomly divided into 3 groups,each group was fed with 2 replicates,each replicates 10 pigs,and the control group was fed with the basal diet,experiment 2 and 3 groups were fed with basal diet supplemented with 50 and 100 mg/kg yeast selenium for 50 days.The growth performance of finishing pigs was measured at the end of the experiment.Conclusion:adding 100 mg/kg yeast selenium to basal diet can improve the growth performance of finishing pigs.
