The data of Phule Triveni crossbred cows of FJG, H, 3H, 4H, 5H and 6H generations maintained at Research Cum Development Project on Cattle, MPKV, Rahuri for a period of 33 years (1977 to 2009) were considered for present investigation. Age at first calving (AFC), lifetime milk yield (LTMY), number of days in milk (NDM), herd life (HL), productive life (PL), lifetime milk yield per day of lactation length (LTMY/LL) and lifetime milk yield per day of productive life (LTMY/PL) were found to be 1001.82 ± 32.86 days, 8728.08 ± 1428.23 kg, 1079.05 ± 140.09 days, 2372.34 ± 173.89 days, 1370 ± 172.81 days, 7.55 ± 0.43 kg and 6.02 ± 0.40 kg, respectively. The effect of sire group, period of birth and season of birth on various traits was also studied. Sire group effect was significant and period of birth and season of birth effect were non-significant on AFC. The effect of sire group, period and season of birth on remaining lifetime traits were non-significant in Phule Triveni cows.
