Feeding management of ewes during lactation

Postpartum ewes experience a gradual increase in milk production, reaching their peak between 4 to 6 weeks after giving birth. After that, milk yield begins to decline around 14 to 16 weeks postpartum. During the pre-lactation phase, ewes rely on rapid utilization of body fluids to maintain milk production, which requires a high intake of energy and protein. This is also the fastest growth period for lambs, making it crucial to ensure sufficient milk supply. By two weeks of age, lambs enter a critical stage for the development of secondary hair follicles, emphasizing the importance of proper nutrition for both ewes and their offspring. To maximize milk output, it's essential to adjust feeding strategies accordingly. From 4 to 6 weeks postpartum, ewes should be given increased amounts of concentrate feed, along with more juicy feeds such as silage and hay. For single lambs, a daily ration of 0.5 kg of mixed concentrate, 1.0 to 1.5 kg of silage, 2.0 kg of hay, and 0.3 to 0.5 kg of carrots is recommended. Ewes nursing twins should receive slightly higher amounts, up to 0.6 to 0.7 kg of concentrate per day. As lactation progresses into its second trimester, the ewe’s milk production naturally declines, even with increased supplementation. At this point, lambs begin to graze and consume solid feed, reducing their reliance on milk. By the time they are three months old, breast milk provides only 5% to 10% of their nutritional needs. It’s an ideal time to gradually wean the lambs and reduce the feeding of the ewes. However, one week before weaning, it's important to decrease the amount of juicy feed, silage, and concentrates to prevent mastitis and ensure a smooth transition for both ewes and lambs.
