Method for selective breeding of white cashmere goats

Abstract

The invention discloses a method for selective breeding of white cashmere goats, which includes: identifying and screening from June 20th to July 20th each year; selecting cashmere goats with cashmere uncombed and complete fleece not shedding, specifically, holding each individual goat standing, pushing aside fleece with hands, observing shedding of the cashmere from skin with eyes, pushing aside the fleece at shoulders, sides, a back, an abdomen and thighs of the goat for observation, determining the goats with the fleece not shedding as primary individual goats growing fleece at all seasons, and grouping the selected primary individual goats growing fleece at all seasons into primary goat flocks growing fleece at all seasons; and screening the primary individual goats growing fleece at all seasons by the same method from June 20th to July 20th in the next year, and grouping the selected primary individual goats growing fleece at all seasons into goat flocks growing fleece at all seasons. Reproduction, feeding management, lambing nursery and epidemic prevention of the goats growing fleece at all seasons are performed according to conventional regulations. The method is low in cost, manual change of genetic material is avoided, farmer can finish selective breeding conventionally, and cashmere weight can be increased evidently.

Description

technical field [0001] The invention relates to a goat breeding method, in particular to a four-season plush cashmere goat breeding method. Background technique [0002] Over the years, the breeding history of cashmere goats has proved that cashmere goats are mainly characterized by long cashmere in the cold season (average temperature ≤ 5°C), and no long cashmere in the warm season. Taking white cashmere goats in Inner Mongolia as an example, it has become a rule that the long cashmere period is from the beginning of September to the beginning of March of the following year, and the rest of the time is no longer long cashmere. [0003] At present, in order to increase cashmere goat production, different methods and means are adopted in various places to realize the perennial cashmere growth of individual cashmere goats. Existing technologies for improving the cashmere production of cashmere goats include: strengthening feeding management and nutritional regulation technolo...

AI Technical Summary

Problems solved by technology

Existing technologies for improving the cashmere production of cashmere goats include: strengthening feeding management and nutritional regulation technology, but the cashmere increase rate is low and the cost is high; transgenic technology, although the technical content is high, has not been applied in production practice, and the technical cost is very high. High; although the embryo transfer technology is used in production, it can only maintain the cashmere production of the original species or strains, and the cost is also very high; the breeding technology of hybrid improved varieties has a very long use time and a low cashmere increase rate; the sun is limited Cashmere-enhancing technology, although the cashmere-increasing rate is leading, but it needs to build a special shed ring; implanted drug cashmere-enhancing technology, although it has obvious cashmere-increasing effect, but the meat quality is no longer pure natural
