This study was conducted to investigate the effects of housing systems on the growth performance and social behavior of the calves. The material of the study was 16 Holstein female calves. The individual group were housed in fiberglass calf hutches (106 width X 118 length X 140 cm height) with individual paddock (136 width X 120 length X 90 cm height) for each calves. In the group housing, group of eight calves were housed in group pens (5.88 m width, 5.20 m length ve 1.75 m height) with feeding and watering facilities. The calves were randomly distributed in the two groups on the basis of their birth weight. The calves were fed with colostrum for first 3 days before allotting to standard milk feeding schedules of the farm ad libitum calf starter, alfaalfa hay and water were introduced from the first week and was continued till the end of the experiment (10 weeks). Each calf was observed twice a week for 1 hour at 8:00, 11:00, 14:00, 17:00 and 20:00 at 10 minute intervals. The results indicated that, group housing system increased the body weight gain, starter intake and alfalfa hay intake, proportional events of playing, walking and standing (p<0.05) compared with the individual housing system of calves.
