Supplementary feed for mink at growth period and preparation method therefor

Abstract

The invention discloses supplementary feed for a mink at growth period. The supplementary feed is prepared from the following components in parts by weight: 70-80 parts of vegetable feed, 10-30 parts of animal feed, 1-5 parts of amino acid feed, 1-5 parts of mineral feed, 0.1-0.5 part of choline chloride, 0.1-0.5 part of a compound enzyme preparation, 0.05-0.2 part of a microbial preparation, 0.1-0.5 part of ethoxy quinoline and 0.5-1 part of additive premix. According to the feed disclosed by the invention, the growth speed, the survival rate and the fur-feather quality of the mink at the growth period are improved, the digestive rate of proteins and fat in the feed is improved, and the diarrhea rate and the feed-grain ratio of young minks are reduced.

Description

technical field [0001] The invention belongs to the technical field of feed utilization, and in particular relates to a supplementary feed capable of improving the digestibility and growth rate of mink feed nutrients and a preparation method thereof. Background technique [0002] Mink is a small and precious fur animal with high economic value. Mink breeding has become an important part of my country's animal husbandry industry structure, and it is also an effective way for farmers to get rich. However, most mink breeding in my country is fed with fresh paste, mainly self-batching. Small and medium-sized farms (households) do not have professional and technical personnel, lack knowledge of feed nutrition, low level of feed formula design and feed preparation technology, and do not have the ability to detect and control feed quality. Meet the nutritional needs of mink growth and development. [0003] Mink fresh paste has high requirements on the freshness of raw materials,...

AI Technical Summary

Problems solved by technology

[0007] ① The nutritional requirements of mink, fox and raccoon dog are different, and the difference is quite large. It is difficult to meet the nutritional requirements of mink during the growth period by feeding mink with general feed products for fur animals;

[0008] ②Existing supplementary feed products are usually common in the growth period and the breeding period, but the nutritional requirements of the growth period and the breeding period are different, so the nutritional content of the product is difficult to meet the nutritional needs of minks in the growth period, and the feed utilization rate is not high;

[0009] ③Existing feed products generally rarely add enzyme preparations and microecological preparations, which is not conducive to the digestion and absorption of nutrients for minks; at the same time, the amino acids, trace elements, vitamins and other ingredients contained in them are usually difficult to meet the nutritional needs of minks
