Abstract
In the last decade, radioisotopes have been used to investigate certain metabolic diseases of animals and radiation is being utilized to produce parasitic vaccines to vaccinate animals. Some studies in which radioisotopes have been used to investigate certain metabolic disorders are reviewed. In experiments where radioimmunoassay technique for the estimation of hormones, has been utilized, the results reveal that the animals on low level of nutrition show greater oestrous cycle lengths or even long anoestrous periods. On the other hand, irradiation has been used as a tool to produce vaccines as well as degradation of certain dietary molecules for increased utilization. A number of studies wherein /sup 35/S and /sup 15/N isotopes have been used, reveal that sulphur supplementation is essential for optimum utilization of nitrogen in the ratio of 1:10. There are certain antimetabolites in feed ingredients which affect endocrine function. Evidence indicates that high nitrate forages disturb thyroid function when sup(131)I is used to elucidate its secretion rate. Similarly certain toxic substances such as tannins have been shown to affect protein metabolism and phosphorus utilization when sup(32)P isotope is used in such studies. The use of radioisotopes has also been helpful to investigate the cause of ''Degnala'' disease

With the help of sup(75)Se it has been possible to trace the metabolic disturbances which lead to the onset of this disease. Another deficiency disease, hyperkeratosis, has been shown to be caused not only because of vitamin A deficiency, but also because of zinc deficiency. The latter helps in the mobilization of a normal quantity of vitamin A from the liver into the blood vitamin A pool. There is wide scope for use of radioisotopes to investigate other metabolic diseases prevalent in livestock in this country.}
