Abstract

The study aimed to establish the normal molybdenum requirements for open ewes of meat-and-fat breeds in arid climatic conditions. The study was carried out in the production conditions of the Buddha farm of the Republic of Kalmykia (Russia). The norm has been established based on a detailed study of the molybdenum content in organs and tissues and the degree of its absorption from the diet, considering the endogenous losses. It has been established that the norm of molybdenum is 4.5 mg per head per day, 2.8 mg per 1 kg of dry matter of the diet and 0.80 mg per 1 kg of live weight of a single ewe. Recommendations have been made to solve the problem of molybdenum deficiency in the diet of open ewes of meat-and-fat breeds in arid climatic conditions of Republic of Kalmykia.
