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（６５ＺｎＭｅｔ）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，６５ＺｎＭｅｔ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＜００５）。
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).
