• Resumen

  • Ten Tudanca bulls ten months old were divided into two groups, 5 animals were castrated using Burdizzo technique and 5 remained entire. After castration animals were fed on grass silage and concentrate (1,5 kg/animal/day) during 119 days and then finished on pasture and supplemented with 1,6 kg of barley and 1 kg of dehydrated sugar beet pulp per animal and day until slaughter at 18 months of age. Castrated animals showed lower daily weight gain than entire ones during the period comprised between castration and turn-out to pasture (p<0.05), but not significant differences (p>0,05) were observed in the period comprised between turn-out to pasture and slaughter. Castrated animals showed lower ( P< 0.05) live weight at slaughter and carcass weight (168 vs 202 kg). The percentage of disseccionable fat from the 6th rib and intramuscular fat content (3,8 vs 2,1%) was higher in castrated vs entire animals while maximum shear force of 7 days maturated meat was lower (4,1 vs 6,3 kg; p<0.05)
