When genetic improvement has been made at the nucleus level, the important question is whether it penetrates to the production herds or is there a genotype by environment interaction between the results from the breeding herds and the results in the production herds? DanAvl has carried out two trials to shed light on this question. The trials included the traits daily gain, lean meat percentage and litter size.

The tables below show how the genetic improvement achieved in the breeding programme is being transferred to the production herds and the results of the best commercial farms using DanAvl genetics for both slaughter pigs and sow units.

Consequently, DanAvl is a breeding programme that does not merely create genetic improvement in the nucleus. It has been established that the production herds benefit from these improvements.
