Abstract

The present investigation was carried on 659 Murrah buffaloes, sired by 188 bulls, maintained at Directorate of Livestock Farms, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, for the duration of 27 years (1991-2017). The purpose of this study was to investigate the average and effect of non-genetic factors on reproductive traits like age at first calving (AFC), first service period (FSP), first calving interval (FCI) and age at puberty (AAP). The overall averages of the various reproduction traits like AFC, FSP, FCI and AAP were  estimated to be 1331.89 ± 8.76 days, 187.61± 4.61 days, 496.75 ± 4.71 days and 1022.51± 8.77 days, respectively. Season of calving had significant influence on FSP, FCI and FDP, whereas, age at first calving had non-significant effect on FSP and FCI.
