Abstract
Material for research served as the integrated fodder additive «Protamine standard». The feed additive «Protamilon standard » prevents a negative energy balance in cattle; increases blood glucose levels, contributing to an additional influx of amino acids; helps to optimize metabolic processes, as well as the replenishment of PSA and prevention of ketosis by stabilizing the sugarprotein ratio and energy balance; is an alternative to expensive energy products. Against the background of the use of bypass additives, an increase in the live weight of bulls was noted, which characterizes their development and improvement of reproductive abilities, which can be realized by using high-quality feed and analyzing and optimizing diets.
