摘要
用杜长大杂交生长育肥猪(17～53千克)试验60天,以卟啉铁替代日粮中的阿散酸。结果表明:两组促生长效果差异不显著,但卟啉铁组比阿散酸组单位增重耗料降低3.1%,单位增重成本降低2.7%。说明应用卟啉铁对生长育肥猪的生长无不良影响,并能提高饲料转化率及经济效益。因此,卟啉铁是一种更具有竞争优势的新型饲料添加剂。
Duroc×(Landrance×Yorkshire)crossed,growing and finishing pigs(17-53kg) were used for the sixty days experiment.Bu quinoline iron substituted arsanilic acid in basal diet.The result showed that the effect on the growth of the two groups were very similar.but in the Bu quinoline iron group,feed to gain ratio decreased 3.1%,cost to gain ratio decreased 2.7%.It concluded that the application of Bu quinoline had no bad effect on growing and finishing pigs.It can improve the utilization of deitary and efficiency,so Bu quinoline iron is a kind of new-type fodder additive with more competitive advantage.
