Fifteen crossbred calves were divided into 3 groups of 5 animals each on the basis of their similar body weight and age. Each group was allotted to three housing system viz. (T1loose house; T2 loose house + bedding + curtains and T3 conventional barn) during winter. Average maximum temperature was significantly (P<0.05) higher in T1 and minimum temperature was higher (P<0.05) in T3 as compared to other two groups in microclimate. The mean respiration rate was higher (P<0.05) in T3 calves as compared to other groups. Average body temperature was higher (P<0.05) in T1 (101.790F) calves as compared to T2 (101.540F)and T3 (101.050F) calves. The total cost/kg body weight gain was lowest in T2 (Rs.129.53) followed by T3 (Rs.131.16) and T1 (Rs. 142.27) groups. Therefore, it is concluded that the modified house (Loose house+bedding+curtains) and conventional barn improves body growth and physical comfort of crossbred calves as well as more economical during winter season in semi-arid zone.
