Genetic evaluation of pigs
The process of evaluating breeding animals follows as the next stage after processing the results of performance testing.
This process is the subject of genetic evaluation of pigs.
The technical implementation of the process, i.e. the mathematical-statistical apparatus describing the acquisition of the genetically “pure” potential of the monitored traits of individuals, is carried out using the mathematical-statistical method:
Best Linear Unbiased Prediction – BLUP. Since we are referring to a Multivariate Animal Model, this is M BLUP AM.
In our conditions, we monitor the breeding values of the following traits:
- average daily gain in field test
- backfat thickness in field test
- average daily gain in performance and carcass value tests
- backfat thickness in performance and carcass value tests
- proportion of valuable meat cuts in performance and carcass value tests
- number of piglets born alive in the 1st litter
- number of piglets born alive in the 2nd and subsequent litters
The output of the genetic evaluation is the estimation of breeding values of the monitored traits and the determination of the overall breeding value (genetic potential of the animal) for all purebred pigs active in breeding. Breeding values are updated weekly.
A TOP ranking of individuals by breed is established for the male and female population.
