预混料是由同一类的多种添加剂或不同类的多种添加剂按一定配比制作而成的匀质混和物，由于添加剂的成分在预混料中占的比例很小。同时在预混料中会增加添加剂，而这些添加剂都是配合营养微量成分进行添加，一般都会添加微量营养性和非营养性成分。长毛兔

　　Premix is by the additives with a variety of additives or different classes of production according to the certain proportion of homogeneous mixture as additives in premix accounted for the proportion of very small. At the same time in the premix will increase additive, and these additives are combined with nutritional trace components are added, usually add trace nutritive and non nutritive components.

　　1、营养性添加剂包括各种维生素、微量元素、氨基酸等，虽然畜禽对这类成分的需要非常微小，但它们却是畜禽生长发育和正常生产所必不可少的。由于动物体内不能合成或合成量不足，这类物质就必须由饲料供给。

　　1, nutritional additives including a variety of vitamins, trace elements, amino acids and so on, although the need of livestock and poultry for this kind of composition is very small, but is livestock growth development and normal production are essential. Because the animal body can not be synthesized or synthesized, this kind of material must be supplied by the feed.

　　2、非营养性添加剂包括抗菌素、药物、抗氧化剂、防霉剂等，这类成分有助于防病抗病，促进生长，防止饲料氧化、结块、霉变等。

　　2, non nutritive additives including antibiotics, drugs, antioxidants, preservatives and other, this kind of composition is help to prevent disease, promote growth, prevent the oxidation of feed, caking, mildew and other.

　　在喂养饲料中添加预混料能快速减少饲料的配合，保证兔饲料中复合丰富的营养成分，补充兔子体内的营养成分。

　　In the feed premix can quickly reduce feed with ensure rabbit feed compound rich in nutrients and the nutrient composition of rabbit in vivo.
