EFFICIENCY OF CHROMIUM ADDITIVES IN DIETS FOR COWS DURING THE FIRST THIRD PERIOD OF LACTATION
Abstract
The paper presents results of studying efficiency of various levels of chromium in diet (100, 115 and 125 %) on performance and quality of cow milk, as well as on physiological processes in animals. Positive effect is determined on studied parameters of increased by 12.5% per 1 kg of dry matter level of the Cr, Zn, Mn, Co, I, Se in diets for high milk yield cows during the 1st third part of lactation with the prevalence of bulky feed in relation to concentrates (43.5:56.5).
