The study aimed to assess the economic efficiency in pig fattening using a new feed ration based on a low-digestible protein and adding the amino acid supplement AminoPro. For this purpose, the experiment included different levels and degrees of protein digestibility in diets supplemented with amino acids. In this way, it was possible to evaluate the fattening qualities of hybrid pigs. The experiment was conducted at the "Ryabushkivsky Bacon" pig complex in the Sumy region with F1 hybrid pigs (VBxL sows x PIC-337 boars). Six groups of 20 pigs, divided by live weight and sex, were fed diets with varying protein digestibility. After a 30-day equalization period, five pigs with extreme weight gains were excluded, leaving 15 animals per group. Over 16 days, pigs were fed either quickly or poorly digestible protein diets with the AminoPro supplement. Dry compound feed was used throughout the experiment. Lightweight piglets on conventional diets with easily digestible protein achieved a final weight of 2.10 kg (1.56%) higher than those with AminoPro. Medium-weight pigs on conventional diets outperformed the experimental group by 2.60 kg (1.84%). Absolute weight gain in pigs fed AminoPro diets was 4.60 kg (6.03%) higher than those on conventional diets. Average daily gains increased by 53 g (6.04%) in medium-weight pigs consuming AminoPro. Feed conversion rations improved in lightweight pigs on conventional diets by 0.07 kg per gain, while medium-weight pigs on AminoPro consumed 0.27 kg less feed per kg of gain. Pigs fed AminoPro diets demonstrated higher fattening quality indices across all weight groups, with significant correlations between initial and final weights. The findings provide valuable insights for optimizing feeding strategies, improving growth performance, and reducing feed costs, contributing to greater profitability in pig production.
