White muscle disease in lambs is the classic sign of Vitamin ____ deficiency?

White muscle disease in lambs is a condition primarily associated with a deficiency of Vitamin E, which plays a crucial role in maintaining healthy muscle and tissue function. This deficiency leads to the degeneration of muscle fibers, resulting in the visible symptoms characteristic of white muscle disease.

Vitamin E acts as an antioxidant, protecting cells from damage caused by free radicals, and is essential for proper muscle metabolism. When lambs do not receive adequate amounts of Vitamin E in their diet, the muscle tissue can suffer from oxidation, causing necrosis and leading to the clinical signs associated with the disease.

Other vitamins listed in the choices are important for a variety of bodily functions as well, but they do not specifically correlate with white muscle disease in lambs. For example, Vitamin A is vital for vision and immune function, Vitamin D is essential for calcium absorption and bone health, and Vitamin K is critical for blood clotting. Thus, while deficiencies in these vitamins can lead to other health problems, they are not linked to the muscle degeneration seen in white muscle disease.
