abstract
The main objective of the present study was to evaluate the performances of Murrah buffaloes by analyzing 265 lactation records over a period of eight years related to the production and reproduction traits that were maintained in an organised farm, Buffalo research station, Venkataramannagudem of West Godavari district of Andhra Pradesh. Data maintained in the farm records on mean lactation milk yield (MLMY), mean lactation length (MLL), mean peak yields (MPY), average age at first service period (AFS), average age at first calving (AFC), average service period (ASP), average dry period (ADP), conception rate (CR) and birth weight (BW) were analysed. The mean lactation milk yield, mean lactation length, mean peak yields, average age at first service period (AFS), average age at first calving , average age at first calving (AFC), average service period (ASP),average dry period (ADP), average calving interval, conception rate (CR) and birth weight observed in the farm were 1723.71 ± 77.64, 293.54 ± 11.23, 10.69 ± 0.46, 36.7 ± 3.66, 49.2 ± 3.29, 164.13 ± 20.3, 173.8 ± 27.03, 459.79 ± 23.02, 58.87% and 29.2 ± 0.56, respectively. From the above data, it can be concluded that murrah buffaloes performance in the organised farm was within the permissible levels and performed well though they were maintained in the hot and humid climatic conditions.
