Breeding method for increasing survival rate of young mink

Abstract

The invention discloses a breeding method for increasing the survival rate of a young mink. According to the method, the feed proportion of a female mink in a suckling period and the young mink is changed according to different time periods, a feeding mode is refined, and the survival rate of the young mink is increased. Feeding of the female mink is controlled (the ratio of the refined feed is gradually increased) to improve resistance of the young mink, secretion of milk is increased, the content of coarse grains is gradually improved by stages after the young mink is weaned, Chinese herbalmedicine components are added, the resistance is improved, and intestinal diseases and infectious diseases are decreased, so that the survival rate of the young mink is increased. The feeding method is reasonable, a feed formula is scientific, feed is green and environmentally friendly, exploration and test are continually implemented in the breeding process, suitable feed ratio and optimal feeding method are determined, flesh of the female mink can lose, digestive absorption of the young mink is good, daily gain is improved, disease resistance is improved, 'yellow fat diseases' and the like of the young mink can be effectively reduced, and the survival rate of the young mink is increased.

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%
