Feeding management of ewes during lactation

Postpartum ewes experience a gradual increase in milk production, reaching its peak between 4 to 6 weeks after giving birth. After that, milk output begins to decline around 14 to 16 weeks postpartum. During the pre-lactation phase, ewes rely on their body fluids to maintain milk production, and their energy and protein requirements are particularly high. This period coincides with the fastest growth phase of the lambs. By two weeks of age, lambs also enter a critical stage for the development of secondary hair follicles. To support both the ewes and their offspring, it is essential to maximize milk yield. During the 4-6 week postpartum period, ewes should be fed more concentrate feed and succulent forages. For single lambed ewes, it's recommended to provide 0.5 kg of mixed concentrates, 1.0 to 1.5 kg of silage, 2.0 kg of hay, and 0.3 to 0.5 kg of carrots daily. For ewes nursing twins, the daily feed amount should be increased to 0.6 to 0.7 kg of concentrates. In the second half of lactation, milk production gradually declines, and even with increased supplementation, it becomes difficult to match the levels seen during the early lactation period. At this time, lambs start to consume grass and other solid feeds, reducing their reliance on milk. By the time they reach 3 months of age, breast milk can only supply 5% to 10% of their nutritional needs. This is when the feeding of the ewes can be gradually reduced or stopped. A few days before weaning, it’s important to reduce the amount of succulent feeds, silage, and concentrates given to the ewes to help prevent mastitis. Proper management during these stages ensures the health of both the mother and the lambs while optimizing milk production and growth.
