铜与反刍动物营养

Copper and the Alimentation of Ruminant

自二十世纪初随着工业化发达国家畜牧业革命性的发展，极大地促进和推动了对动物营养广泛深入的研究，尤其微量元素对动物的营养意义及重要性得到了证明。铜作为反刍动物预防临床和生长的必须元素逐渐得到证实，其营养意义主要表现在作为动物体内多种酶的组成部分参与氧化磷酸化、结缔组织交联及毛发生成等生理过程而起作用，另外，还是葡萄糖代谢、骨骼矿化、免疫机能等动物机能代谢必须的微量元素。目前，已在反刍动物现代化饲养中得到广泛使用。本文作者主要就铜在自然界和反刍动物体内的含量和分布及反刍动物生理吸收与代谢、生物学功能和对铜的缺乏症、耐受量等方面进行阐述和讨论。

At the beginning of 20th century, with the revolutionary development livestock husbandry in developed industrialization countries, the study of the alimentation of animal was pro- moted widely and deeply , especially the animal＇s alimentation need for microelement and the mi- croelementg importance to animal have been attested. Copper as the necessary element of the ru- minant prevention of disease and growth have gradually attested, its meaning of nutrition primary express at the main part of many kinds of enzyme in animalg body attends the oxidation of phos- phorus oxide, connective tissue cross - linkin, hair grow and so on . The copper can make some affect to the animal. On the other hand, copper is the necessary element of dextrose metabolizabili- ty,cadre mineralization, immunity and other enginery metabolizability. Now, it is widely using in the modern animal breeding. The writer mainly talk about the copper in the environment, its con- tent and distributing in the body of the ruminant, the ruminant absorb and metabolizability, biologi- cal function and copper lack, the quantity of copper animal can take.
