Quick Answer
Pregnant ewes require adequate protein, energy, and essential micronutrients to support fetal growth and milk production. They need a balanced diet rich in fiber, vitamins, and minerals to ensure healthy lambing and lactation. A well-formulated feed or supplement can significantly impact lamb growth and survival.
Essential Nutrient Requirements
Pregnant ewes require a diet rich in energy to support fetal growth, milk production, and maintenance of their own body weight. A general recommendation is to provide 0.25-0.30% of the ewe’s body weight in dry matter per day, with a crude protein content of 12-14% and a total digestible nutrients (TDN) of 50-60%. This can be achieved through a high-quality hay or silage supplemented with grains or concentrates.
Vitamin and Mineral Requirements
Pregnant ewes also require essential vitamins and minerals to support fetal development and lactation. A key requirement is vitamin A, which is crucial for fetal development and immune system function. A daily intake of 200-300 IU/kg body weight is recommended. Additionally, pregnant ewes require adequate levels of vitamin E, selenium, and copper to support immune function and prevent reproductive problems.
Practical Feeding Strategies
In practice, pregnant ewes can be fed a combination of high-quality hay or silage, supplemented with grains or concentrates. A typical feeding strategy involves providing 1-2% of the ewe’s body weight in grains or concentrates per day, in addition to ad libitum access to hay or silage. Ewes should be fed in a group to promote social interaction and reduce stress. It is also essential to monitor the ewes’ body condition score and adjust their feed intake accordingly to ensure they are not over- or underfed.
