Growth performances and carcass characteristics of Nero di Lomellina and commercial hybrid pigs: preliminary data

In the 2020, the Nero di Lomellina pig, an autochthonous pig from the area of Pavia, has been recognized as reconstructed Italian pig breed by the National Pig Breeders Association (ANAS). No data on Nero di Lomellina growth performances and carcass characteristics are available. The aim of the study was to investigate the effects of the pig genetic type (Large White vs Nero di Lomellina) on growth performance and carcass characteristics. Ten Large White pigs and ten Nero di Lomellina pigs born in winter season were selected and were monitored till slaughter. The animals were weighted at different timepoints and the average daily gain (ADG) was calculated. At slaughter, seven animals per genetic type were selected and hot carcass weight, weight of green ham and loin were recorded. The live weight at birth, weaning and growing phase resulted higher (P<0.05) in Large White than Nero di Lomellina pigs. At slaughter, the live weight was comparable (P>0.05) in both genetic types. The carcass yield was about 83% and the ham weight was about 17 kg, with no difference between genotypes. The present preliminary data suggest that in the first phase of breeding there are some differences in growth performances between commercial hybrid pigs and Nero di Lomellina pigs. However, no difference in carcass weight and carcass characteristics were observed. Further data on Nero di Lomellina pigs are needed to confirm the present results and to evaluate meat quality parameters.
