First, pregnant ewes

During the first 30 days after pregnancy is confirmed, it's important to maintain stable feeding conditions and avoid frequent changes in diet. For ewes that were naturally bred, they can be allowed to interact with rams or view them through a fence between 18 to 25 days post-mating to confirm pregnancy. Once confirmed, ensure that the ewes receive moderately nutritious feed to maintain their health and activity level. This helps them stay strong and prepared for the upcoming lactation period. In the last month of pregnancy, gradually increase the nutritional content of their feed to help them build up energy reserves for peak milk production. However, avoid overfeeding, as excessive weight gain can reduce milk yield. Instead, focus on high-quality, balanced feeds rather than high-energy concentrates.

Second, lamb care

(a) The early stage: For the first 10 days after birth, the main source of nutrition for the lamb is colostrum. Rich in nutrients and antibodies like globulin, colostrum plays a vital role in boosting the lamb’s immune system. The amount of colostrum should be at least 1/5 of the lamb’s body weight. If the farmer is not experienced, the lamb can nurse from the ewe for the first six days before being weaned onto bottle feeding.

(b) The feeding period: After the first 10 days, whole milk can be introduced until around 40 days of age. Ensure the lamb receives enough milk to feel full, while also offering small amounts of easily digestible, high-quality concentrates and hay to support digestive development.

(c) The milk and forage period: From day 41 to 80, the lamb should have access to milk, grass, and other feed sources. Provide high-quality legume hay, along with a mix of barley, oats, corn, bran, and soybean meal to support growth and development.

(d) Weaning period: Between day 81 and 120, the lamb should transition to mainly forage. If quality hay and by-products are available, weaning can occur as early as 90 days without affecting the lamb’s growth. Gradual weaning ensures a smooth transition and better long-term health.

Third, lactating ewes

Lactating ewes are typically kept in pens and require a well-balanced diet. For every kilogram of milk produced daily, provide about 5 kilograms of fresh grass or sweet potato vines during summer and autumn, plus 0.25 kg of corn flour, 5 grams of bone meal, and 10 grams of salt. Make sure they have access to clean water. In winter and spring, offer 2 kg of high-quality hay or dried sweet potato vines, peanut vines, or soybean pods, along with 300 grams of corn flour, 5 grams of bone meal, and 10 grams of salt. Warm water should always be available. As milk production increases, adjust the concentrate accordingly. Ewes producing 1.5 to 2.5 kg of milk per day should receive 0.7 kg of corn flour, while those producing 3 to 3.5 kg should get 1 kg of corn flour. Keep male and female sheep in separate groups and allow them to graze for 2 to 3 hours daily. Regular exercise and sunlight exposure are essential, and maintaining a clean environment helps prevent disease and improve overall productivity.
