摘要/Abstract

摘要： 为了探索不同铁源对哺乳仔猪生长、代谢和环境的影响,选用15窝共158头哺乳仔猪随机分为Ⅰ、Ⅱ、Ⅲ组,分别饲喂含硫酸亚铁、柠檬酸铁和蛋氨酸铁的3种饲粮(饲粮铁含量为146mg·kg^-1)进行补铁效果试验.结果表明,Ⅱ、Ⅲ组仔猪在35日龄试验结束时的体重、日增重、体况行为等级、血液血红蛋白值、血浆转铁蛋白含量、血浆和肝脏铁含量等指标均显著(P<0.05或P<0.01)高于Ⅰ组;饲料消耗、腹泻发生率、排粪量、粪中含铁量和排铁量则显著(P<0.05或P<0.01)低于Ⅰ组.Ⅲ组35日龄体重和日增重也显著(P<0.05)高于Ⅱ组,但其余指标在Ⅱ组和Ⅲ组之间无显著差异(P>0.05),说明蛋氨酸铁和柠檬酸铁可明显改善仔猪的健康状况、生长发育、饲料报酬和血液生理生化指标,促进铁在猪体内的吸收和利用,降低排粪量和粪中排铁量,不失为给哺乳仔猪补铁的高效而安全的铁源.

Abstract: In order to approach the effect of different source Fe on piglet's growth, metabolism and environment,an experiment was conducted with 158 suckling pigs from 15 litters,which were randomly allocated to group Ⅰ,Ⅱ and Ⅲ,and fed with diet Ⅰ(basal diet+FeSO₄·H₂O),Ⅱ(basal diet+Fe-citric acid)and Ⅲ(basal diet+Fe-methionine complex),respectively.Each of the diets contained 146mg·kg^-1 Fe.The results show that after the experiment ended, the body weight,daily increment,grades for appearance and behavior,hemoglobin concentration in blood, Fe transferring albumen concentration in plasma,and Fe contents in plasma and liver of 35 days old piglets in group Ⅱ and Ⅲ were higher(P<0.05 or P<0.01)than those in group Ⅰ,while the feed conversion,diarrhea incidence, fecal amount and its Fe content of the piglets in group Ⅱ and Ⅲ were lower (P<0.05 or P<0.01) than those in group Ⅰ.The body weight and daily gain of the piglets in group Ⅲ were also higher (P<0.05) than those in group Ⅱ, but no significant differences (P>0.05) in other traits between group Ⅱ and Ⅲ. It is suggested that Fe-methionine complex and Fe citric acid could improve piglet's health,growth and development,feed conversion,and physiological and biochemical parameters,increase the absorption and utilization of Fe by piglet's body,and decrease the fecal amount and its Fe content.Both of them should be effective and safe Fe sources for suckling pigs.
