摘要
在基础日粮中添加不同配比水解羽毛粉氨基酸螯合物铁和锌,研究其对断奶仔猪日增重和粪便中残留量的影响。选取60头体重相近的杜×长×大三元杂交仔猪,随机分为5组,其中1组为对照组,另4组为试验组。实验结果表明,综合日增重和粪便中残留量两项指标,B1组(80%铁、60%锌)平均日增重为0.588kg/d、粪便中铁锌含量与其他组相比最低或相同,因此,我们选择B1组为水解羽毛粉螯合铁、锌在断奶仔猪日粮中的最佳配比。
To study the effect of different proportion of feather meal chelated iron and zinc on average daily gain（ADG） and the residues in feces of weaned piglets,60 Duroc×Landrance×Yorkshire cross weaned piglets were randomly divided into five groups（one control and four treatment）.The result indicated that： ADG of group B1（80% iron and 60% zinc） was 0.588kg/d,and the Fe Zn residues in feces in group B1 was lower than others groups.Therefore,group B1 was determined as optimal proportion in dietary for weaned piglets.
