The use of premixes in feeding of replacement young cattle

Abstract

Insufficient intake of minerals into the body of young animals leads to the fact that calves have a lag in growth and development, which aff ects the overall health and further productivity. The study of the feasibility of using premixes with improved formulations in feeding replacement young cattle is relevant. The purpose of the research was to study the increase in the efficiency of rearing replacement heifers, their achievement of earlier economic and physiological maturity due to the use of premix Megamix Noris and Megamix Vitula Opti in the rations of calves. The scientific and economic experiment was carried out under the conditions of OOO “EkoNivaAgro” in the Bobrovsky area in the Voronezh region. Comprehensive studies have been carried out to study the effectiveness of the use of the studied premixes, developed according to improved recipes, in the rations of replacement heifers. It has been experimentally proved that the use of premixes Megamix Noris (up to 6 months of age) and Megamix Vitula Opti (from 6 to 12 months of age) it contributed to an increase in the live weight of replacement heifers for the period of the experiment by 7,74 %, the increase in average daily gains by 8,63 %. An analysis of the economic eff ectiveness of rearing replacement heifers showed that the additional profit from the sale of young animals in live weight amounted to 38,7 thousand rubles. When calculating the level of economic eff ectiveness of milk production, it was revealed that the studied premixes as part of the rations for replacement heifers contributed to obtaining additional profit from the fi rst-calf heifer in the amount of 2,288,29 rubles, which led to the increase in the level of profitability by 3,08 abs.%.
