Fully expanded granular feed for mink and preparation method thereof

Abstract

The invention relates to a feed for minks, and in particular relates to an all-expanded pellet feed for minks, and a preparation method thereof. The all-expanded pellet feed for the minks takes grain feeds, imported fish meal, imported meat and bone meal, grease, small peptide protein and additives as main raw materials, and is prepared by mixing the raw materials according to certain parts by weight. The all-expanded pellet feed for the minks is easy to prepare, can be produced in an industrial way, is comprehensive and balanced in nutrition, high in rate of absorption and utilization, low in ratio of the meat to the feeds, and low in pollution, and effectively solves the breeding problem of advanced farmers and the convenience for feeding can be realized.

Description

(1) Technical field [0001] The invention relates to a feed for minks, in particular to a fully expanded granular feed for minks and a preparation method thereof. (2) Background technology [0002] Mink is a rare fur animal raised artificially in my country. It has been introduced from abroad in 1958 and has a history of more than 50 years. China's current mink farming is mostly based on family gardens, and there are also large-scale large-scale farms in a certain proportion. The feed for mink feeding is mainly fresh fish meat, offal of livestock and poultry, corn, grain, etc., which are cooked, crushed and mixed before being fed to minks. [0003] There are the following problems in the breeding of mink today: [0004] (1) The nutritional standards of the feed used for feeding minks are different, and the amount of nutrients required by minks in different periods cannot be well supplied, which reduces the fur quality of minks; [0005] (2) The primary understanding of fee...

AI Technical Summary

Problems solved by technology

[0004] (1) The nutritional standards of the feed used for feeding minks are different, and the amount of nutrients required by minks in different periods cannot be well supplied, which reduces the fur quality of minks;

[0005] (2) The primary understanding of feed nutrition and processing prevents the feed from being well absorbed and utilized, increasing the pollution of excreta to the surrounding environment;

[0006] (3) It is difficult to grasp the source and quality control of raw materials, and large-scale large-scale farms also have a large number of mink deaths due to raw material quality problems every year;

[0007] (4) The original breeding mode restricts the large-scale development of minks. When fresh materials are used, the number of minks that each breeder can manage during the growth period is at most 800-1000. This year's labor shortage and The increase in labor costs is restricting the development of mink farming scale, the larger the farm, the more obvious it is
