Abstract

The aim of the study was to analyze the hereditary predisposition to hernias in pigs based on the evaluation of offspring from breeding boars under production conditions. Methods. Study was conducted on the pig farms in the Kyiv region. A total of 7,500 young pigs obtained from five boars of different genetic backgrounds were analyzed. Hernias were diagnosed using clinical examination methods. The overall incidence of hernias and the proportion of inguinal-scrotal hernias were assessed. Statistical analysis included the Pearson’s chi-square (χ²) test, as well as the calculation of relative risk (RR) and odds ratio (OR). Results. It was established that the overall incidence of hernias was 22.4%, with substantial variation depending on the breeding boar, ranging from 3.3% to 41.2%. The highest incidence was observed in the offspring of the hybrid boar OptiMus, whereas the lowest rates were found in the offspring of purebred Landrace and Yorkshire boars. Inguinal-scrotal hernias accounted for more than 80% of all cases. A statistically significant dependence of hernia incidence on the origin of the offspring was identified (χ², p < 0.001). The relative risk of developing hernias in the offspring of certain boars reached 10.6, while the odds ratio reached 17.2. Conclusions. The obtained results indicate a pronounced hereditary component in the development of hernias in pigs and confirm the feasibility of using progeny testing to identify undesirable genetic traits. These findings can be applied to improve breeding programs aimed at reducing the prevalence of this pathology.

Key words: pigs, hernias, hernia prevalence, heredity, breeding boars, selection, inguinal-scrotal hernias.
