摘要
钙是动物体内含量最大的无机盐,钙不仅是构成骨组织的主要矿物质成分,而且在机体各种生理和生物化学过程中起着重要作用。钙对动物的重要作用是不可替代的,钙缺乏病是常见的营养性疾病,但是钙过量又会对动物造成不良影响和危害。因此,在动物饲粮中应合理添加钙。文章对国标方法(KMn O4法和EDTA络合滴定法)中影响饲料中钙含量测定的关键影响因素进行分析。
Calcium is the most abundant inorganic salt in animals, which is not only the main mineral composi- tion that constitutes bone tissue, but also plays an important role in various physiological and biochemical processes. Calcium plays an irreplaceable role in animals and calcium deficiency is a common nutritional disease. Excessive cal- cium can cause adverse effects and harm to animals and its should be added reasonably in animal diets. In this paper, the key factors affecting the determination of calcium by the National standard method （KMnO4 method and EDTA complexometric titration） in feed were analyzed.
