Pelleted feed for lactation period of minks and preparation method

Abstract

The invention discloses pelleted feed for the lactation period of minks. The pelleted feed comprises components in parts by weight as follows: 30-50 parts of animal nutrients, 20-40 parts of plant nutrients, 5-15 parts of Chinese herbal medicines, 1-5 parts of vitamins, 1-5 parts of microelements, 2-5 parts of zymosan, 2-5 parts of propolis, 1-5 parts of bifidobacterium, 1-5 parts of lactic acid bacteria, 2-5 parts of stachyose, 2-5 parts of Saccharomyces cerevisiae and 2-10 parts of ethoxyquin. A preparation method comprises steps as follows: (1) preparation of raw materials; (2) synthesis of a biological material; (3) conversion into a cooked material; (4) expansion and pelleting; (5) drying; (6) spraying coating; (7) vacuum drying. With the adoption of the pelleted feed, the growth speed of the female minks can be increased, the feed conversion efficiency can be improved, the female minks are good in hair color, the feed cost during breeding is reduced, and the survival rate of young minks of the lactation minks is increased.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a mink lactation pellet feed and a preparation method thereof. Background technique [0002] Feed preparation plays a very important role in the breeding and production of mink, which not only determines the profit prospect of farming, but also determines the transformation and upgrading of the industry. Excellent feed and additives can not only greatly reduce the loss of feed raw materials, but also make the breeding of fur animals convenient and efficient, and the fur quality of the farmed fur animals is good. [0003] In the existing mink breeding process, there are few high-quality special compound feed varieties, and most farmers still stay in the extensive breeding stage of feeding some livestock and poultry meat and grains. The unbalanced diet not only greatly reduces the growth rate of minks, but also causes some diseases in minks because of the lack of certain trace elemen...

AI Technical Summary

Problems solved by technology

In the existing feeds, the feed for the lactation period of mink has not been successfully developed. Usually, other feeds are used to replace the lactation ration during the breeding process, which will cause malnutrition and insufficient milk in the lactation mink

In addition, in the existing full-price compound feed for mink, because the process of processing the feed must go through the process of heating, extruding, forming and pelleting, some nutrients such as heat-sensitive vitamins are easily lost or damaged during the production process, which reduces the quality of the feed. nutrient content
