摘要：The article presents material on the effect of the amino acids lysine and methionine in pig diets. Studies have been carried out to increase the live weight of animals, depending on the content of these amino acids in the diet when fattening up to 100 and 120 kg. Presented research results obtained during testing in certified and accredited laboratories. When growing gilts to live weight from 30 to 50 kg, a deficiency in the level of lysine was found, which reaches up to 29.6%, and methionine with cystine up to 23.1%. When growing animals from 81 to 120 kg of live weight, the lysine deficiency is 14.9%, and methionine with cystine is 8,8%. This necessitated balancing the diet of animals to the required level of amino acid content. The most effective on the growth and development of animals, as well as on indicators of pork quality, was the introduction of feed lysine in combination with methionine in pig diets.
