Breeding sheep refers to the young sheep from weaning to the first mating. 3-4 months after weaning, the growth and development is fast, the intensity of weight gain is high, and the feeding conditions are high. After 8 months of age, the growth and development intensity of sheep decreased gradually. The key points of feeding and management in the early stage of breeding in this period, especially in the newly weaned lambs, the growth and development is fast, the rumen volume is limited and the function is not perfect, and the utilization ability of roughage is poor.
