Result: Revealed that 14.80% of the total female calves born died while 17.53 percent of total female calves were culled, before reaching the milking herd. Only effect of period was significant on total mortality. Age specific mortality among female calves from 0-1, 1-3, 3-6, 6-12 and 12 month to age at first calving was noted as 5.87, 3.06, 2.13, 1.68, and 3.13 percent, respectively. While, Age specific culling among female calves from 0-1, 1-3, 3-6, 6-12 and 12 month to age at first calving was recorded as 0.47, 0.70, 1.82, 4.72 and 13.17 percent, respectively. The period of birth had highly significant effect (p<0.01) from birth to 1month as well as significant effect (p<0.05) by period and season of birth was recorded on 1-3 months age mortality. Conclusion is that the early phase of life is more crucial for calves survival. So, rigorous feeding and healthcare management are required to reduce involuntary disposal.
