Abstract
Genetically determined stress sensitivity in pigs is one of the most well-known problems encountered in pig meat production and processing. Given the economic importance of pig meat production, efforts are made to avoid this condition, as it can increase mortality rates in the final stage of production and cause issues for the meat industry due to poor meat quality. Such meat is unsuitable for market or processing due to unfavorable physical and chemical characteristics. The aim of the study was to explain the mechanism behind malignant hyperthermia syndrome in stress-sensitive individuals, identify factors contributing to this condition, describe pig breeds susceptible to stress sensitivity, and define the impact of stress sensitivity on meat properties and quality. Additionally, it aimed to propose preventive measures to ensure economically viable pig meat production without losses. Alongside genetic analyses and selection against the mutated RYR1 gene, efforts to reduce stress in pigs also involve stricter animal welfare legislation that ensures proper handling of animals. Providing adequate transport conditions, appropriate microclimatic conditions on farms and in transport vehicles, gentler handling immediately before slaughter, and proper stunning methods can minimize stress in pigs, thereby avoiding negative changes in meat quality. The current situation in the Republic of Croatia is satisfactory. Laboratory analyses have not detected the presence of recessive homozygotes, with only a small number of heterozygotes for the gene responsible for stress sensitivity being identified.
