Animals on natural browse do not need vitamin supplements. Vitamin injections These should only be used to deliver specific vitamins in cases where a specific vitamin deficiency is known to exist. We are totally opposed to the routine use of vitamin injections - in most cases, they serve no useful purpose and indeed are a frequent cause of introduced infection via the injection site. Very few deficiencies are so acute that the much more effective and safer oral delivery route is not a satisfactory mode of treatment. Acute vitamin-A deficiencies may be dealt with by injection, but few other cases require this treatment.
Vitamins are organic substances which help regulate bodily functions.
Acting as co-enzymes, vitamins aid the action of enzymes during the metabolism of dietary nutrients. There are about a dozen major vitamins, a deficiency of any one of which will result in a serious deficiency disease. Vitamins are only required in relatively small quantities, but have a major effect upon the body's reproductive, digestive, nervous and muscular systems. Vitamins also affect tissue growth and anti-body production. Plants contain carotene which is converted to true vitamin-A in the body.
