MICROELEMENT STRUCTURE OF MEAT IN FOALS OF YAKUT BREED OF THE NATIVE TYPE, OF PRILENSKAYA AND MEGEZHEKSKAYA BREEDS IN YAKUTIA

Abstract

Results are given from investigations into the microelement structure of meat in foals reared under different natural-climatic conditions of Yakutia. It is shown that the microelement structure of meat is dependent on a breed and a zone of horse rearing. Under conditions of excess moistening, the fodder plants of alaas meadows in Central Yakutia accumulate the maximum amount of mineral substances that is a cause of their high contents in meat of foals of Yakut breed of the native type. The meat of foals of the native type was revealed to have the significant advantage over that of the young stock of Prilenskaya and Megezhekskaya breeds because of high contents of iron, manganese, copper, zinc, iodine, fluorine, and selenium. The natural-climatic conditions, where horses of Prilenskaya and Megezhekskaya breeds are reared, somewhat differ from those of Central Yakutia. Abundant all-year-round precipitation and early frosts result in reducing nutritive and biological value of green plants on small-valley meadows. The contents of toxic elements (lead, cadmium, mercury) in the meat of foals of the breeds studied were within the limits of permissible concentrations.
