The purpose of the study was the effect of lysine in the diets on the performance and slaughter indices of pigs during fattening. Young pigs of the experimental group, for the introduction to the diet of lysine, for 100 days of fattening had a greater live weight of 7.7 kg, or 6.4%. Control slaughter of pigs about the same indices of slaughter output of carcasses at the level of 84.0-86% in the experimental with a difference of slaughter weight by 4.3 kg in favor of the experimental group. A lower yield of internal fat and average fat thickness of 13.0% in experimental pigs was found, which confirms a more intense synthesis of muscle tissue. The content of total and bound moisture in muscle tissue was higher by 4.7% and 7.5%, respectively, in the pigs of the experimental group against control, but lower by 2.5% of free moisture. The consequence of these indicators is a lower solid content of 4.5% in the experimental group of pigs.
