Mink breeding season breeding feed and preparation method

Abstract

The invention relates to a mink breeding season breeding feed. A preparation method comprises the following steps: (1) cleaning various raw materials, removing silt and iron impurities, and then, performing crushing treatment on all solid raw materials; (2) weighing 20 to 40 parts of corn powder, 10 to 30 parts of imported fish meal, 10 to 30 parts of chicken powder, 5 to 10 parts of blood powder, 1 to 5 parts of malt, 0.5 to 1 part of cotton oil, 0.5 to 1 part of yeast and 0.5 to 1 part of multi-vitamins, mixing for the first time, and quickly tempering and aging; (3) mixing the aged feed which is prepared by mixing for the first time for the second time, adding 10 to 20 parts of soybean oil, pressing into particles through a granulator, and cooling to prepare a finished product. The feed prepared with the preparation method can supplement various proteins, fat, vitamins, trace elements and mineral substances which are required in a mink breeding season, so that the breeding success rate is improved; the disease incidence rate of a mink is reduced; the cub survival rate is improved; the digestive absorption of the proteins, the fat and carbohydrate in digestive tracts of the mink can be promoted; the micro-ecological environment of gastrointestinal tracts of the mink can be improved; the feed cost can be reduced; the mink fur quality and the breeding economic benefit are improved.
