No documentary evidence was found in the scientific literature on the efficacy of injections (of vitamins A, D and E) on the alleviation of stress and the prevention of weight loss in export cattle. Research work on fat soluble vitamin supplementation of cattle at pasture suggests that animals rarely need or benefit from vitamin supplementation except perhaps in situations of prolonged droughts when vitamin A deficiency may be a problem. A short period on a 'green pick' or a mineral block with vitamin A will eliminate the need for this vitamin.
