In: Alexandria Science Exchange Journal 2013.v.34(1)Summary: The study was carried out by the Department of Animal Production, Faculty of Agriculture, Alexandria University, Saba Bache, Alexandria, Egypt. Buffaloes were reared at Trust Farm. The farm is located in Km 40 Alexandria-Cairo desert road after Ameria City. A trial was conducted to raise buffaloes in open sheds under routine managerial practice . The mean body weights of heifers at birth, weaning and first service, together with the high pre-weaning daily gain showed that the desert conditions did not exert adverse effects on it. The mean calving interval (403.6±2.6 days) was near to the ideal calving interval which permits nearly a calf every year. Total milk yield per lactation averaged 1600 ±11 kg• Such results indicated that the Egyptian buffaloes responded well to good managerial procedures. Year of calving affected significantly (P<0.001) first service weieht, daily gain from weaning to first service and from birth to first service, days open and lactation period. Season of calving and parity effects were significant (P<0.001, 0.01 or 0.05) on most of the traits studied.
