The present investigation was conducted to study the effect of various non genetic factors like farm, parity, period of calving and season of calving on different production traits like total lactation milk yield (TLMY), 305 day milk yield (305MY), peak yield (PY), milk yield per day of lactation length (MY/LL) and milk yield per day of calving interval (MY/CI) in Murrah buffaloes. The data analysed include records of 2959 buffaloes, progeny of 219 sires maintained over a period of 24 years (1992-2015) at Buffalo research centre (BRC), LUVAS, Hisar and Animal farm ICAR-CIRB, Hisar. The least squares means for TLMY, 305MY, PY, MY/LL and MY/CI were 2165.1341.55 kg, 2093.2536.16 kg, 11.010.14 kg, 6.370.059 kg and 4.260.052 kg respectively. Least squares analysis of variance indicated significant effect of parity on TLMY, 305MY and PY. The effect of period and season of calving was statistically significant on all the production traits under study except the non-significant effect of season of calving on MY/LL. Analysis of variance also revealed significant effect of farm on TLMY, PY and MY/LL. Significant effect of various non genetic factors on production traits helps to conclude the importance of lactation number, season and managemental farm activities in production performance of Murrah buffaloes.
