What is the primary disease associated with vitamin E deficiency in livestock?

The primary disease associated with vitamin E deficiency in livestock is white muscle disease. This condition primarily affects young animals, especially in species such as cattle and sheep. Vitamin E plays a crucial role as an antioxidant, protecting muscle and tissue integrity. When there is a deficiency of vitamin E, oxidative stress occurs, leading to muscle degeneration and necrosis, which manifest as white muscle disease.

The disease is characterized by stiffness, weakness, and damage to the skeletal muscles and heart muscles, ultimately resulting in muscle degeneration. Pregnant or lactating animals that do not receive sufficient vitamin E may also have offspring that are more susceptible to this condition, highlighting the importance of adequate vitamin E intake during critical life stages.

Other conditions listed, such as foot rot, black leg, and Johne's disease, are not directly related to vitamin E deficiency but rather involve bacterial infections or other nutritional or environmental factors. Understanding the relationship between vitamin deficiencies and specific diseases is essential in managing the health of livestock effectively.
