The effect of gene CTSL on the quantitative and qualitative production traits of pork meat

Cathepsin L (CTSL) affects the proteolytic system of meat in pigs. Moreover, this gene belongs to the candidate genes for economically important traits in pigs. The objective of this study was to test the influence of mutation AJ315771:g.143C > T in the CTSL gene on qualitative and quantitative traits in pigs. The association analysis performed within this project tested the effect of the CTSL gene in 514 crossbred combinations. These pigs are commonly raised on commercial
farms in the Czech Republic. No statistically significant differences were detected in qualitative traits. However, we identified a trend of allele T on increased fatness and the effect of allele C on lean meat.
