Start by selecting healthy ewes and rams with strong fertility. Sheep typically breed in the fall and estrus can be managed with hormones. Natural breeding or artificial insemination can be used, but make sure rams are in good health. Additionally, keep records of breeding, pregnancy, and lambing to track and improve reproduction in your flock.

Nutritionally, keep ewes in good body condition before breeding, and "flush" them with extra feed to boost fertility. During late pregnancy, increase feed for fetal growth, ensuring a balanced diet with necessary minerals. After lambing, provide a high-energy diet to support milk production. 

This involves vaccinating against diseases like Chlamydia and Campylobacter. This also includes breeding, lambing, and managing parasites on pasture. Shearing or crutching before lambing keeps the area clean for nursing.  

Provide clean, dry shelter for lambing to prevent hypothermia. Monitor closely for complications such as difficult births and ensure lambs receive colostrum quickly, while dipping navels in iodine to prevent infection.
