Vitamin A is the most important vitamin in cattle nutrition. It is the only one which normally must be added to cattle diets. It is necessary for bone development, sight, and maintenance of healthy epithelial tissues (i.e. lining of digestive and reproductive tracts). A deficiency can cause an increased susceptibility to disease, night blindness and reproductive failure. Vitamin A needs special attention in beef cattle rations. This vitamin is found only in animals. Plants, however, are the natural source of vitamin A activity for animals. Green and yellow plants contain carotene, a pigment which animals convert to vitamin A.
The wall of the small intestine is the principal site for email data of carotene to vitamin A. Some metabolic functions of vitamin A are not yet known. A chief role is maintenance of epithelial tissue (skin and lining of respiratory, digestive and reproductive tract) in a healthy condition. It also functions in visual purple, a compound in the eye needed for sight when an animal adapts from light to dark. Vitamin A is essential for proper kidney function and normal development of bones, teeth and nerve tissue. One of the first easily detected signs of vitamin A deficiency in cattle is night blindness.
An easy way to check for this condition is to place an obstacle in the pathway of cattle and notice if they stumble over it at twilight. Other early signs are loss of appetite, rough hair coat, dull eyes, slowed gains and reduced feed efficiency. Diarrhea and pneumonia may be the first indicators, especially in young animals. Vitamin A injected in the muscle is used more efficiently to increase liver stores than that given in the feed. This method is often used to supply vitamin A to new feeder cattle. The intramuscular injection of 500,000 to 6 million IU of vitamin A in cows two months before calving has been used in numerous experiments with range and farm herds.
There has been no benefit in many cases in respect to fertility, calving percentage or weaning weights. vitamin because ultraviolet light acting on a compound on animal skin changes that compound into vitamin D. Vitamin D is found in sun-cured forages. Animals kept outdoors or fed sun-cured hay do not usually suffer a deficiency, whereas animals kept indoors and fed silage may do so. Animals manufacture their own vitamin D requirements from sunlight and fresh or dry feed.
