A Breeding Method for Improving the Survival Rate of Young Mink

Abstract

The invention discloses a breeding method for improving the survival rate of young minks. The method changes the feed ratio of lactating female minks and young minks according to different time periods, refines the feeding mode, and improves the survival rate of young minks. By controlling the feeding of the female mink (gradually increasing the proportion of fine feed) to improve the resistance of the young mink and increase the secretion of milk; after the weaning of the young mink, gradually increase the content of coarse grains in stages, and add Chinese herbal medicine ingredients to improve resistance and reduce intestinal The occurrence of road diseases and infectious diseases, thereby increasing their survival rate. The feeding method of the present invention is reasonable, the formula of the feed is scientific, and it is green and environment-friendly. Through continuous exploration and experimentation in feeding management, the appropriate feed ratio and the best feeding method have been determined, so that the female mink does not lose fat and the young mink digest and absorb Yes, the daily gain is increased, and the disease resistance is enhanced, which can effectively reduce the occurrence of diseases such as "yellow fat disease" in young minks and improve their survival rate.

Description

technical field [0001] The invention relates to the technical field of mink breeding, in particular to a breeding method for improving the survival rate of young minks. 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] The existing mink breeding technology is not systematic and standardized, and the following problems exist in the current mink breeding: [0004] (1) The ...

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 feed from being well absorbed and utilized, increasing the pollution of excreta to the surrounding environment;

[0006] (3) The source and quality control of raw materials are difficult to grasp, 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

[0012] However, there is no detailed report on the breeding technology of young mink

At present, in the breeding process of young minks, there is a risk of high mortality of weak fetuses, and they will die at the age of 3 days if they cannot eat colostrum; young minks with no appetite, reduced sucking power, and weakened vitality will die at the age of 3-5 days;7 It is the peak period of the death of young minks within the age of 10 days, up to 75%
