摘要
Twelve male 8-month-old lambs were used in a 6-month feeding experiment to determine the effects of dietary Mo, Mo + S and Zn supplements on the body retention and tissue accumulation of dietary Cu, Zn and Fe. The lambs were divided into four groups of three lambs each and each group was fed ad libitum one of four diets. A control diet was based on palm kernel cake (PKC) and grass hay. Three additional diets were the control supplemented with either Mo or Mo + S or Zn. At 3 months of the experiment, feces and urine were collected and sampled for 6 days. At the end of the experiment (6 months), blood was sampled and then the sheep were slaughtered. The liver and kidney were removed and sampled for chemical analysis. In comparison with the control, each dietary supplement decreased (P P P > 0.05). It was concluded that from the supplements tested, only Mo + S appeared to be effective in reducing the retention and liver accumulation of the dietary Cu to prevent chronic Cu toxicity in sheep fed PKC-based diets.

在6个月的喂养实验中使用12只雄性8月龄羔羊，以确定日粮Mo，Mo + S和Zn补充剂对日粮Cu，Zn和Fe的体内保留和组织积累的影响。将羔羊分成四组，每组三只羔羊，每组随意喂食四种日粮中的一种。对照饮食基于棕榈仁饼（PKC）和草干草。另外三种饮食是对照，补充有Mo或Mo + S或Zn。在实验的3个月时，收集粪便和尿液并取样6天。在实验结束时（6个月），对血液进行取样，然后对绵羊进行屠宰。取出肝脏和肾脏并取样进行化学分析。与对照相比，每种膳食补充剂减少（P P P> 0.05）。结论是，从测试的补充剂中，只有Mo + S似乎有效减少膳食Cu的保留和肝脏积累，以防止饲喂基于PKC的饲料的绵羊的慢性Cu毒性。
