Breeding sheep refers to young sheep aged from the first weaning to the first breeding. After 3-4 months of weaning, the growth and development are fast, the weight gain strength is high, and the feeding conditions need to be high. After 8 months of age, the sheep's growth and development intensity gradually decreased. First, the feeding and management of the early breeding period. In this period, especially the newly weaned lamb, fast growth, limited rumen volume and imperfect function, the ability to use roughage difference. Therefore, during this period, the sheep's diet should be mainly concentrated, and be able to supply high-quality hay and green sweat feed, the crude fiber content of the diet does not exceed 15-20%. Second, the rearing of the breeding management point The rumen function is basically perfect, and it can feed a large amount of pasture and silage, micro-storage straw. The proportion of roughage in the diet can be increased to 25-30%. At the same time, concentrate feed or high-quality silage and hay must be added. The management of the sheep during the breeding period directly affects the sheep's early reproduction and must be taken seriously. The female lamb is 40 kg in weight at the age of 6 months and can reach the breeding level at 8 months of age. Eighty percent of the female lambs in the current year participated in the breeding breeding of the year, and the rearing of the breeding period was crucial.
