Abstract

A total of 182 pigs from one farm and comprising 65 boars (B), 65 gilts (G) and 52 castrates (C) from 48 litters, were reared from birth to 89 kg live weight. Sex of pig did not influence age at slaughter but B compared with G and C had lower killing-out proportions (0·748 v. 0·756 v. 0·753) and reduced backfat measurements. Skin damage in transit to slaughter and/or in lairage was more prevalent in B compared with C, with G being intermediate. Muscle pH measurements were not influenced by sex except ultimate pH of the m. semispinalis capitis, where B compared with G and C had a higher incidence of values above 6·1 (0·246 v. 0·060 v. 0·120). Carcasses of B had proportionately more shoulder (0·04 unit) and more leg (0·011 unit), at the expense of middle, than those of C with G being intermediate. Weight losses in the preparation of de-boned sides for curing were higher in carcasses of B compared with G and C.
