Data on 479 Murrah buffaloes over a period of 24 ye ars from 1990 to 2013 related to early and lifetime performance traits were collected from history sheet s maintained at Buffalo Research Centre, LUVAS, Hisar. Al l the early performance traits had positive genetic trend s that varied from 14.97±4.95 kg/period, 0.04±0.02 kg/period, 0.03±0.01 kg/period, 0.34±0.68 days/period and 1.83 ±1.06 days/period for FLMY, FPY, FLMY/FLL, FSP and FCI, respectively. The genetic trends for lifetime perfo rmance traits were found to be negative for LTMY, PL and HL traits while it was positive and very low for MY/PL and MY/HL . Positive genetic trends for FLMY, FPY and FLMY/FLL a nd negative phenotypic trends for FCI and FSP are in des irable direction. Moreover, negative genetic and ph enotypic trends for LTMY, PL and HL are suggestive and indic ator to streamline the breeding policy for attainin g the desired genetic improvement for ameliorating the productive life as well as herd life there by taking care of L TMY.
