Why is mineral supplementation necessary in the diets of pregnant ewes?

Mineral supplementation is essential in the diets of pregnant ewes primarily to support fetal development. During pregnancy, ewes have increased nutritional requirements to ensure that the developing fetus receives adequate nutrition for proper growth and development. Essential minerals, such as calcium, phosphorus, magnesium, and trace minerals like copper and selenium, play crucial roles in various biological functions, including bone formation, muscle development, and overall metabolic processes.

For instance, calcium and phosphorus are vital for skeletal development, while trace minerals are important for enzyme functions and immune system support. A deficiency in these minerals can lead to complications such as weak lambs, increased lamb mortality, and health issues for the ewe, affecting both the mother and the offspring's well-being. Thus, ensuring that pregnant ewes receive adequate mineral supplementation is essential for optimal reproductive performance and healthy offspring.
