Sixteen crossbred calves were selected on the basis of nearness in body weight and age from the herd. These crossbred calves were grouped into four groups for feeding different trials as complete feeds with wheat straw 50% (T1 ), sunflower heads straw 50% (T2 ), sunflower heads straw 30% + subabul meal 20% (T3) and Sunflower head straw 25% + wheat straw 25 % (T4). The treatment effect on feed intake DM intake was significant over experimental period and it was higher in T2 treatment . The water intake per DMI was not dependant on dry matter consumption as the calves from T1 treatment consumed significantly less dry matter over other treatment. Growth performance of calves from T2 treatment showed higher growth rate than other treatment. SFH could be incorporated in the diets of calves at 50% level without any adverse effect on acceptability, palatability and nutrient utilization.
