Effects of a change in the carcass classification system of pigs on the genetic evaluation of breeding stock. Estimation of genetic parameters for new selection traits in French Large White and French Landrace pigs



Effects of a change in the carcass classification system of pigs on the genetic evaluation of breeding stock. Estimation of genetic parameters for new selection traits in French Large White and French Landrace pigs



Techni Porc 21(1): 27-31



The genetic parameters for lean yield and carcass yield, estimated by the European Union carcass classification system, and for muscle percentage, were determined using a BLUP animal model, based on data on 5828 and 2465 barrows of the 2 breeds respectively. In the French Large White pigs, hsuperscript 2s of the former and new measures of carcass yield were 0.44 and 0.42, and those of muscle percentage and lean yield were 0.76 and 0.69.
