At the present stage of development of market economy, one of the most important tasks of the agricultural sector in Russia is to increase the production of agricultural products, which depends on the sustainable development of livestock industries and their intensification based on modern achievements. The agro-industrial complex and its basic type of economic activity - agriculture - are the leading system-forming spheres of the economy of the Chuvash Republic, which form the agri-food market, food and economic security, labor and settlement potential of rural territories. One of the tasks of the Chuvash Republic State program “Development of agriculture and regulation of the market of agricultural products, raw materials and food of the Chuvash Republic” for 2013-2020 is to stimulate the growth of production of main types of agricultural products and food products. A prerequisite for increasing agricultural production is increasing livestock productivity. The experience of using biological stimulants and feed additives under qualified use, with a predetermined task and in optimal quantities, indicates a rather high economic efficiency and safety for animals and humans. Research has been conducted to study the effect of para-aminobenzoic acid on the quality of meat in young cattle. The experiments were carried out in the educational experimental farm of the Chuvash State Agricultural Academy. Three groups of young cattle were formed on the principle of 15 animals each. The control group received the main diet, to the first experimental group, para-aminobenzoic acid was added to the main diet at a dose of 0.5 mg per 1 kg of live weight, the second experimental group – 1 mg per 1 kg of live weight. An organoleptic assessment of the quality of meat and meat broth indicates the biological usefulness of the meat of bull-calves treated with para-aminobenzoic acid. The chemical composition of the meat of bull-calves does not change significantly with the use of this vitamin.
