Primal joints and hind-leg cuts of entire and castrated Javan rusa ( Cervus timorensis russa) stags

Abstract

The effects of castration on the primal joints and the cuts of the leg joint of Javan rusa ( Cervus timorensis russa) stag carcases was investigated at three slaughter ages (13, 19 and 25 months). Castration reduced the weights of some primal joints in the 19- and 25-months age groups, but not at 13 months. At 19 months, the neck, and neck plus chuck, were heavier by 35 and 17% respectively in entires ( P<0.05), and at 25 months entires had heavier carcases, shoulder, forequarter and hindquarter ( P<0.05). The leg and saddle joints were approximately 39 and 18% of the side, respectively, for both treatments and all ages. The proportions of the neck, and neck plus chuck, were higher ( P<0.05) in 19-month old entires than castrates. There were few significant differences between treatments in the weight or proportion of the hind leg cuts at any slaughter age, but in the 25-months group the silverside was 8% ( P<0.05) heavier in entires. In both castrates and entires, there appeared to be an increase in the percentage of the rump as the animals grew from 13 to 19 months of age.
