Reproductive performance records of an Egyptian buffalo herd raised in Egypt were collected in the period from 1970 to 1985. Data on 2946 records including 430 buffalo cows (Paternal half sisters) representing 51 sires were used to estimate the genetic and phenotypic parameters of age at first Calving (AFC), birth weight of calf (SW'), Calving to service interval (CFS), insemination period (IP), days open (DO) and calving interval (Cl'). Averages of AFC and BW were 38 month and 35kg, while averages of CFS, IP, DO and CI were 166, 37, 203 and 500 days, respectively. Most reproductive trails (e.g. CFS, IP and DO) decreased linearly as parity advanced_ Parity had significant ( P < 0.001) effects on CFS, tr, Do and Cl. Season of calving affected significan by (P
