Winter lamb feeding and management
For lambs born during the winter, special attention must be given to several key areas to ensure their health and survival. First and foremost, maintaining a warm environment is crucial. The temperature in the breeding house should be kept between 8°C and 10°C, while the lamb's area should remain above 8°C to prevent cold stress and promote comfort.
Immediately after birth, it’s important to clear any mucus from the lamb’s nostrils to ensure proper breathing. Then, allow the ewe to clean the lamb’s body naturally. If the ewe does not show interest in nursing, you can sprinkle wheat bran or corn flour on the lamb to encourage the ewe to take notice and begin suckling.
Colostrum, the first milk produced by the ewe within three days of giving birth, is essential for the lamb’s immunity. Rich in antibodies, vitamin A, and protein, colostrum plays a vital role in strengthening the lamb’s immune system and preventing diseases like diarrhea. Make sure the lamb nurses as much as possible during the first few days.
To support the production of high-quality milk, the ewes should be fed a balanced diet rich in green, juicy, and succulent feeds such as lettuce leaves, ryegrass, radishes, and red leeks. In addition, supplement their feed with concentrates like corn, bran, and rice bran to ensure sufficient milk supply for the lambs.
If a ewe has low milk production or dies, it’s advisable to foster the lamb to another nursing ewe. Choose a ewe with strong maternal instincts and high milk production. Since ewes identify their lambs by scent, you can help them accept the foster lamb by applying the nursing mother’s milk to the foster lamb’s body at night or rubbing the lamb’s urine on the mother’s nose. This helps confuse the ewe’s sense of smell. After placing the lamb with the nursing mother, it usually takes about 2–3 days for successful bonding.
By day 15, start introducing supplementary feed to the lambs. Offer a mix of corn flour, barley flour, wheat bran, and soy flour. The feeding amounts should increase gradually: 50–70 grams per day for lambs aged 15–20 days, 100–150 grams per day for those aged 21–30 days, and 200–250 grams per day for lambs aged 31–60 days.
Lambs are generally sexually mature and active around 7–10 days after birth. At this stage, they should be allowed to enjoy some time outdoors in the sunlight. Start with short periods of 30–60 minutes and gradually increase the duration. By day 20, they can begin grazing alongside the ewes. If the ewes are kept indoors, provide a play area where the lambs can move, jump, and exercise to support healthy skeletal development.
