Vitamin A 5000 Blend
Vitamin A 5000 Blend provides 5000 IU of Vitamin A to promote eye health and night vision. Also important for skin health, bone formation, immunity, fetal development, gum health, and gene activity.
Vitamin A is one of the fat soluble vitamins, meaning it is stored in the body. It is commonly deficient in dried forages that do not have a good green color or are more than one year old. It is an essential nutrient, critical for normal vision, immune function, gene action, fertility and development of the fetus, normal bone metabolism, red-blood-cell production, normal skin, hoof, and eye surfaces and is also an antioxidant.
Fresh, nondormant pasture grasses have the highest concentration, old grass hays the lowest. Roughages that are green, leafy and not too old will contain carotene, which can be converted to Vitamin A by the horse, but roughages that are bleached or have been weathered and are dark and dusty will not contain sufficient Vitamin A content.
The vitamin A requirement of adult horses at maintenance is 30 IU/kg (1 kg equals 2.2 pounds) of body weight. For growing and exercising horses, it is 45 IU/kg of body weight. A 500-kg (1,100-pounds) horse would therefore need 15,000 IU of vitamin A per day at rest and 22,500 IU per day when working.
The proposed upper safe limit of intake is around 160,000 IU per day for a 500-kg horse.
The most common signs of Vitamin A deficiency are dry, scurfy skin and hair coat, runny eyes and night blindness. A few studies have shown night blindness can actually be induced by depriving the horse of Vitamin A and then fixed by adding sufficient Vitamin A back in to the diet. Hooves may be dry and scaly. There’s also a slower resistance to respiratory issues, stress and diarrhea.
