Abstract
The objective of this experiment was to compare the pork quality of entire male pigs and pigs immunized against GnRF (IC males) at both light (64.8 kg) and heavy (106 kg) liveweights and two feeding regimes (restricted at 2.5 times maintenance and ad libitum). There was no difference in objective measurements (P > 0.05) or eating pork quality (P > 0.1) between entire male and IC males. Fail rates were reduced by 9.1% and 12% for pork from IC males for quality grade (P = 0.007) and re-purchase intention (P = 0.001), respectively, compared to pork from entire males. Skatole (P = 0.001) and androstenone (P < 0.001) levels in belly fat were higher in entire male than IC male pigs. In addition, 3..
