Abstract

The present investigation was conducted to analyze the effect of non-genetic factors on milk production traits of Murrah buffaloes. Data were collected from 2,67,599 daily milk yield (DMY) records of 445 buffaloes from 2001 to 2016 and analyzed using fixed linear least-squares analysis. The overall least-squares means for DMY, 305MY, TLMY, LL, PY and DPY were 7.66±0.01 kg, 2258.17±95.73kg, 2465.48±130.72 kg, 340.48±14.14 days, 13.17±0.45 kg and 63.45±7.26 days, respectively. Analysis of variance indicated significant effect (p<0.01) of period of birth, period of calving, parity and stage of lactation on DMY. Increasing trend was observed for DMY across the periods of calving. Parity had significant effect (p<0.05) on all the production variables except TLMY and the buffaloes were found to attain peak average production (10.13 kg) during second stage of lactation. All production traits had increasing trend across period of calving. Season of calving had significant effect (p<0.05) on PY and DPY. The results indicated that accurate estimation of the effect of non-genetic factors on production traits would help in developing effective management and selection strategies.
