Quick Answer
A proper diet during the lambing phase is crucial as it directly affects the health, growth rate, and survival of lambs. A well-nourished pregnant ewe will give birth to strong, healthy lambs that can thrive on their own more easily. Proper nutrition also influences ewe's reproductive performance and her ability to rebreed after lambing.
Importance of Nutrition for Pregnant Ewes
Pregnant ewes require a diet rich in energy, protein, and minerals to support the growth of lambs. A diet that provides at least 1.5 times the maintenance energy requirements of non-pregnant ewes is recommended. This can be achieved by increasing the energy density of the diet through the use of high-energy concentrates such as grains or by extending the grazing period.
Nutritional Requirements for Newborn Lambs
Newborn lambs require colostrum, the first milk produced by the ewe, to provide essential antibodies and nutrients. Lambs should be allowed to nurse for at least 24 hours after birth to ensure they receive adequate colostrum. The quality and quantity of colostrum can be improved by feeding ewes a diet rich in energy and protein during the last 6-8 weeks of pregnancy.
Management Strategies to Support Ewe and Lamb Nutrition
Sheep producers can implement management strategies such as rotational grazing and strategic feeding to support ewe and lamb nutrition. Rotational grazing can improve pasture quality and ensure that ewes have access to high-quality feed during critical periods such as pregnancy and lactation. Strategic feeding of ewes and lambs can also help to optimize growth rates and improve overall health.
