Abstract: The study was carried out to compare growth, weight gain and feed efficiency traits of Brown Swiss calves which were fed milk replacer and raised in individual, group and individual +group housing systems. Weights, gains in weights and body measurements at various ages were determined. The results revealed that group-housing could be attractive concerning growth rate of Brown Swiss calves, easiness and economical construction of the group pens, although young animals in group pens had slightly less favourable feed conversion efficiency ratio.
