Contenido: 	ABSTRACT.

Thirty Holstein calves were assigned to the following treatments groups: T1=bulls (n=10); T2=cryptorchids (n=10) and T3=steers (n=10). All animals had an initial liveweight (LW) of 150±21 kg fed with the same diet based on an oversown pasture grazed at 5% of LW and at 2.5% LW+supplementation at 1% LW using entire corn grain (winter). Information of carcass yield and meat quality was recorded. Daily live weight gain presented differences amongst treatments, being T1=T2> T3 (P<0.01). Higher values of hot carcass weights and carcass yield were observed (P<0.01) in T1 and T2 compared with T3. There was a significant effect (P<0.01) of the animal gender in main cuts (striploin, tenderloin, sirloin and outside flat) weights, being higher (P<0.01) for T1 and T2 compared with T3, and also in most of each cuts weights measured. The results on meat quality traits show that marbling values and fat colour where higher for T3 (P>0.01). For muscle colour, no differences were found among treatments, but a trend of lower values was observed (P<0.05) for T1 (less brightness, red level and yellowing). These results suggest that in Holstein beef production systems, gender could play an important role to improve productivity and carcass traits.
