Abstract

Introduction: The wholesale value of pig carcases is influenced by the market price of each primal cut while carcass value to the producer is determined by weight and subcutaneous fatness levels. The middle cut (loin and belly) is economically more valuable than the leg and shoulder cuts (Australian Pork Limited, 2021). Therefore, genetic improvement of total carcase value can occur by increasing the proportion of these highvalued cuts. Weights of retail cuts at different growth stages are phenotypically related to the size and shape of the live animal (Doeschl-Wilson et al., 2005). Further, Sarker et al. (2021) showed live animal measurements are heritable and could be used as genetic predictors of primal cut weights to improve total carcase value via indirect selection of pigs with a higher proportion of high-valued cuts. The present study aimed to estimate genetic correlations between primal cut weights and length and area measurements of live pigs.
