Ewe feeding and management
1. Feeding Management Before Mating Before mating, it's essential to properly manage and rejuvenate the ewes to ensure they receive adequate nutrition for successful breeding. Along with dietary supplements, maintaining normal metabolism is crucial, especially for lean or weak ewes after weaning, as they need additional nutrients to regain strength. At the sheep farm in Qinshui County, Boer ewes are primarily fed a combination of dry forages like hawthorn vines and peanut stalks, which they can graze on freely for about four hours daily. In addition, each feeding session includes a mix of concentrates at approximately 0.4 kg per ewe.

Feeding and Management During Pregnancy During the first three months of pregnancy, the fetus develops slowly, so nutritional needs are similar to those of non-pregnant ewes. However, during the second trimester, around 80% of the fetal weight is gained within two months, making it critical to provide sufficient and high-quality nutrition. During this time, the metabolic energy should be increased by 15–20%, and calcium and phosphorus levels should rise by 40–50%. Vitamin A and D must also be adequately supplemented. For Boer sheep in the muddy water area, the feeding before pregnancy is similar to the non-pregnant period. In the later stages of pregnancy, ewes are given 0.6–0.8 kg of concentrate daily, along with 3–5 g of bone meal. About 10 days before birth, more juicy feed should be provided. Pregnant ewes require careful management to avoid stress, overcrowding, sudden movements, and slipping, as these can lead to miscarriage. They should move slowly and steadily, avoiding moldy or frozen feed. 3. Feeding and Management During Lactation Lactation typically lasts from 2 to 3 months postpartum. In the first two months, milk is the primary nutrient source for lambs, especially in the first 15–20 days after birth. Ewes must be fully fed to meet their high energy demands. Boer lambs gain about 200–250 g per day during lactation, requiring approximately 100 g of milk for every 100 g of weight gain. To produce 500 g of milk, ewes need about 0.3 kg of air-dried feed or 33 g of protein, along with 1.2 g of calcium and 1.2 g of phosphorus. As lambs grow and start eating more solid feed, the amount of concentrate for the ewes can gradually decrease until it’s completely stopped. Nursing ewes should have controlled concentrate intake—especially in the first 1–3 days after birth, when overfeeding can cause digestive issues. Succulent feed and concentrates should be reduced gradually before weaning to prevent mastitis. The lambing area should be kept clean and disinfected regularly, with placenta and hairballs removed promptly to avoid disease transmission. On water-breeding farms, Boer ewes receive 1–2 kg of juicy feed and 0.6–1 kg of concentrate daily, in addition to free-choice hay. Lambs are usually introduced to commercial piglet feed 15–20 days after birth and gradually transitioned to green feed. Weaning typically occurs around 2 months of age.
