預混料是由同一類的多種添加劑或不同類的多種添加劑按一定配比制作而成的勻質混和物，由于添加劑的成分在預混料中占的比例很小。同時在預混料中會增加添加劑，而這些添加劑都是配合營養微量成分進行添加，一般都會添加微量營養性和非營養性成分。長毛兔

　　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、營養性添加劑包括各種維生素、微量元素、氨基酸等，雖然畜禽對這類成分的需要非常微小，但它們卻是畜禽生長發育和正常生產所必不可少的。由于動物體內不能合成或合成量不足，這類物質就必須由飼料供給。

　　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、非營養性添加劑包括素、藥物、抗氧化劑、防霉劑等，這類成分有助于防病抗病，促進生長，防止飼料氧化、結塊、霉變等。

　　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.

　　在喂養飼料中添加預混料能快速減少飼料的配合，保證兔飼料中復合豐富的營養成分，補充兔子體內的營養成分。

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