A Trial of Environment Protection Additives for Feeding Weanling Pigs

选择相同品种断奶仔猪 2 4头 ,随机分三组 ,每组 8头 ,分别喂以不含抗生素、含抗生素及含天然活性成分 (即环保型 )添加剂的日粮 2 7d。平均日增重分别为 0 .5 2 4,0 .5 5 0和 0 .5 45kg,料肉比分别为 2 .5 1 ,2 .35和 2 .2 6 。

Weanling pigs were divided into three groups in random, eight pigs in each group were fed with the diets without antibiotics or with antibiotics and the environment protection additives for 27 days. The average daily weight gain was 0.524, 0.550 and 0.545 kg respectively, and the ratio of feed conversion was up to 2.51, 2.35 and 2.26 respectively. However, the production performance and the economic efficiencies of the group fed with the diets containing the additives with native activity were higher than others.
