Modified feed special for mink in molting period and preparation method thereof

Abstract

The invention discloses a modified feed special for a mink in molting period and a preparation method thereof, the feed is prepared from the following materials at a ratio: corn, pumpkin, white fish meal, pork, oxalis corymbosa herb, chicken liver, egg shell powder, citrus peel, root of stellaria yunnanensis, trifolium inflorescence, lotus seed, sodium humate, oxytetracycline and diatomaceous earth; the feed is rich in methionine and selenomethionine and has the advantages that the intake of selenium, protein and vitamin in the mink culture process is ensured; self-biting behaviour and concurrent yellow fat disease caused by excessive mercury, sodium chloride and iodide for mink in molting period is effectively avoided; the feed is not easy to get moldy, and the skin peripheral nerve itching caused by chronic food poisoning of the mink can be avoided; the organism immunity is improved, and the organism endocrinology can be regulated; the physique of the mink, the fertility and hair quality can be obviously improved, the breeding cost and risk are reduced, the breeding economic efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of mink breeding, in particular to an improved feed specially used for the moulting period of mink and a preparation method thereof. Background technique [0002] Mink is a precious fur animal. Mink fur is a kind of precious fur. It is known as the "King of Fur". Mink has high economic value and good economic benefits. Comfortable, mink fur, fox fur and Persian lamb skin are the three pillar commodities in the world fur market; the main product of mink is mink fur, and its by-products are mink heart, mink whip, mink oil, mink meat, viscera and mink dung, etc. It has high practical value and economic value. [0003] Artificial mink breeding has become a new special breeding industry. Although it is only in recent decades in our country, especially in recent years, there has been a spontaneous upsurge of mink breeding all over the country.

[0003] Artificial mink breeding has become a new special breeding industry. Although it is only in recent decades in our country, especially in recent years, there has been a spontaneous upsurge of mink breeding all over the country. Many farmers have achieved Considerable economic benefits; since the mink is a strict carnivore, its digestive tract structure is very simple, the food emptying rate is fast, and there are very few microorganisms in the intestinal tract, so the mink largely relies on enzymes for digestion, and the mink The ability to self-regulate feed intake is poor, and it is easy to overeat; while most of the minks currently on the market are fed with fresh food and concentrated feed, it is impossible to clarify the mink’s demand for protein and amino acids, which affects the healthy growth of mink. Reduce the reproductive capacity of breeding mink, the survival rate of young mink, and the quality of fur. At present, most mink breeding adopts the breeding method of one cage per cage. Faced with the threat of self-biting disease, self-biting disease is a chronic disease of caged mink, characterized by paroxysmal nervous hyperactivity, violent self-biting of a certain part of the body, causing self-biting trauma and affecting its growth and fur quality, Moreover, the incidence of the disease remains high during the moulting season in spring and autumn every year, which brings serious economic losses to the artificially cultured mink industry, increases the cost and risk of breeding, and reduces the economic benefits of breeding; A significant increase in the amount of sulfur-containing amino acids leads to a lack of sulfur-containing amino acids. Although sulfur-containing amino acids are used as additives in the prior art, the absorption is poor and the utilization effect is not ideal; based on the above reasons, it is aimed at self-biting and other complications that are prone to occur during the moulting period of mink , improve the quality of its hair, and improve the economic benefits of mink breeding are technical issues that are urgently needed to be studied and solved by those skilled in the art
