Scope

Scope: This document specifies the environmental requirements for the rearing and management of high-prolific Albais cashmere goats on farms, selection criteria for breeding goats, the introduction of genetic material from polytocic breeds, improving the reproductive performance of male and female goats, increasing the proportion of goats of reproductive age, and the use of drug preparations and hormone immunization methods, as well as daily feeding and management. This document applies to the rearing and management of high-prolific Albais cashmere goats. Main technical content: 3. Terms and definitions. The following terms and definitions apply to this document. - Reproductive efficiency: The percentage of lambs born in the current year relative to the number of breeding females at the end of the previous year. The calculation formula is as follows: Formula: F = reproductive efficiency; B = total number of lambs born in the current year; P = number of breeding females at the end of the previous year. 4. The environmental conditions of the farm should comply with the requirements of NY/T 388. 5. Selection criteria for breeding goats: Select breeding females that can produce two lambs in their first lactation as breeding females. Select goats with good physical characteristics as breeding females. The average cashmere yield should be 782 g, and the average body weight after shearing should be greater than 43 kg. 6. Introduction of genetic material from polytocic breeds: Select polytocic females from reserve breeding goats and reserve breeding females for conservation and expansion of the gene pool to improve reproductive performance. Aim to achieve a reproductive efficiency greater than 160%. 7. Improve the reproductive performance of male and female goats: Meet the nutritional needs of goats in the two months before mating. On the one hand, extend the grazing time, return home early and late, and ensure that goats have sufficient feeding time. On the other hand,
