The data on 1721 calves from Sahiwal and Jersey-Sahiwal crossbred cattle were utilized for studying the age specific mortality and culling rate. The overall mortality and culling rate were found to be 15.92 and 19.52 per cent in Sahiwal and Jersey crossbreds respectively. The average female calf mortality from 0-1, 1-3, 3-6, 6-12 and 12 month to age at first calving was observed as 5.81, 2.92, 2.06, 1.75 and 5.01 per cent, respectively.
