The feed additive comprises the following components in parts by weight: 20-40 parts of eels, 10-20 parts of tendons, 6-12 parts of goose liver, 6-12 parts of enteromorpha prolifera powder, 3-7 parts of shell powder, 4-8 parts of fish scales, 2-3 parts of lactic acid bacterium powder, 4-6 parts of haws, 6-10 parts of apple residues, 4-8 parts of passion fruits, 6-8 parts of fermented bean curd residues, 3-5 parts of pine needle powder, 6-8 parts of rice bran, 5-9 parts of snail powder, 8-16 parts of carrots, 6-12 parts of dragon fruits and 4-8 parts of olive oil. The feed additive can promote the growth of the minks, enhance the immunity of the minks, improve the fur quality of the minks, and increase the economic benefits of the mink raising households.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for promoting the growth of mink, and also relates to a preparation method of the feed additive. Background technique [0002] Mink fur is a kind of precious fur, which has various varieties and colors, and is expensive. It has the laudatory title of "King of Fur". Judging from the quality and value of mink fur, its utilization rate is also higher than that of large capillary fur such as fox and raccoon fur, especially in the domestic market with great potential.

Problems solved by technology

However, since fox, raccoon dog and mink are of different genus, the individual body weight and digestive physiological structure characteristics are completely different, and the same feed formula cannot provide comprehensive and balanced nutrition for the growth of mink, so the existing feed and feed additives cannot target Inadequately meeting the demand for nutrients in the production process of mink breeding will easily lead to slow growth of mink, low utilization rate of feed, dim coat color, poor fur quality, and it is difficult to meet market requirements, which also affects the economic benefits of farmers
