In modern pig farming, it is important to provide animals with complete sources of protein to increase the efficiency of fattening and the quality of meat products. A promising solution is the use of feed additives based on insect larvae, which are distinguished by high nutritional value, the presence of biologically active substances and a balanced amino acid composition. The aim of the work was to assess the effect of protein powder from insect larvae ProtiNOVA, obtained from the larvae of the insect Hermetia illucens, on the productive and meat characteristics of pigs. The study was conducted on animals of the F2 genotype, obtained from crossing Camboro pigs (Large White × Landrace) with PIC 337 boars. In the diet, soy protein concentrate was replaced by the introduction of protein powder from insect larvae ProtiNOVA at the rate of 20 kg/t of feed for up to 71 days. The fattening period of pigs lasted up to 173 days. The results of the experiment allowed us to assess the effectiveness of using insect protein as an innovative component of the pig diet. It was found that the inclusion of ProtiNOVA in the diet contributed to an increase in carcass weight and muscle tissue yield (by 2.4 %), while simultaneously reducing the relative proportion of fat tissue by 1.2 pp. and improving the “muscle cell” area by 12.9 %. No significant differences in the percentage of bone tissue were found between the groups. A comparative analysis of the weight of the internal organs of the pigs showed insignificant differences between the groups and no negative effect of the supplement on the physiological state of the animals. In animals that received a protein supplement from insect larvae, a slightly larger weight of the liver, heart, spleen, stomach and pancreas was observed, while the kidneys and lungs had lower values compared to the control. The results obtained indicate that the use of insect protein supplements contributes to the increase in meat productivity of pigs and can be considered as a promising alternative to traditional protein sources in compound feeds without worsening the morphofunctional characteristics of the carcass.
