USE OF ECONOMIC COMPLEX INDICES OF BREEDING VALUE IN PIG PRODUCTION
Abstract
The aim of the presented work was to establish the relationship between the index assessment of animals and the measurement values of the selected traits included in the index assessment. The research was conducted on the population of pigs of two planned breeds, Landrace and Yorkshire, having a sufficient number of animals with measured values of selected traits of their own productivity and available in the state information system in the field of pedigree pig breeding as of December 31, 2022 in the number of 2,915 main sows and 76 main stud boars. It was found that all selected traits included in the complex indices of sows and stud boars had positive correlation values of medium and high degree: for sows: average daily gain – 0.915-0.835, prolificacy – 0.179-0.487, litter weight at weaning – 0.482-0.377; for stud boars: backfat thickness – - 0.297 – ( - 0.225) for Landrace and Yorkshire breeds, respectively, average daily gain - 0.999, which indicates the possibility of using the developed indices in selection and breeding work.
