Ech group of animals were slaughtered at 500 and 550 kg. liveweight.

During the fattening period the average daily liveweights gains in the groups were determined as 865.8 and 873.1 g .respectively. Feed intakes (Concentrate + hay) were 8.57 and 8.80 kg/kg gain respectively. Dressing percentages in the groups were 54.8 % and 55.8% respectively. Animals slaughtered at 550 kg. had more first quality cuts.
