Vitamin E is an essential nutrient to our birds to function normally. Vitamin E is a fat-soluble vitamin with antioxidant properties.Vitamin E is the most powerful antioxidant vitamin, its prime function is to help scavenge free radicals. Free radicals can harm cells, tissues, and organs. They are believed to play a role in certain conditions associated with aging. The benefits of vitamin E for a good health also include its ability to regulate vitamin A in the body. Vitamin E protects vitamin A and essential fatty acids from oxidation in the body cells and prevents breakdown of body tissues, the B vitamins and Vitamin C from oxidation, and helps ensure the efficient use of Vitamin K1 and an efficient use of oxygen by the blood and muscles. Necessary for the reproductive system, birds before the breeding season supplemented with Vitamin E produce a better fertility.
The main sources of vitamin E in the diet are vegetable oils (especially safflower oil, sunflower oil, and cottonseed oil), green leafy vegetables, nuts, cereals, meats, egg yolks, wheat germ, and whole wheat products.
Vitamin E deficiency is rare, and may occur in birds with diminished fat absorption through the gut, malnutrition, very low-fat diets, several specific genetic conditions, very low birth weight young birds. Vitamin E supplementation is accepted as an effective therapy for vitamin E deficiency to halt progression of complications.
