Abstract:

An experiment was conducted to evaluate excretive tendency of zinc in feces and urine with 8 goats groups fed with diet Ⅰ (basal diet+ 65 Zn Met) and diet Ⅱ (basal diet+ 65 ZnSO 4) respectively. The results showed that 65 Zn concentration in feces of the goats fed with diet Ⅰ was lower than that of the goats fed with diet Ⅱ, and the absorptivity of zinc from Zn Met was significantly higher than that from 65 ZnSO 4(P<0 05).

Key words:  65Zn-Met , 65ZnSO4, goat , excretive tendency

摘要:

8只体重为9kg左右的健康浏阳黑公山羊,分成两组,单独关在代谢笼内,分别喂以含65Zn蛋氨酸(65ZnMet)和65Zn硫酸锌(65ZnSO4)的饲料,比较研究锌蛋氨酸螯合物的中锌在山羊粪、尿中的排泄动态。结果表明,65ZnMet组在粪中排出65Zn的浓度显著低于65ZnSO4组,日粮Zn的表观吸收率极显著地高于65ZnSO4组(α<005)。
