In the present study, breeding information spread over a period of 14 years, was collected from the history-cum-pedigree sheets and milk yield registers of Murrah buffaloes maintained at four centres of Network Project on Murrah Buffalo Improvement (National Dairy Research Institute, Karnal; Central Institute for Research on Buffalo, Hisar; Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana and Choudhary Charan Singh Haryana Agricultural University, Hisar). Data on first lactation traits of 832 Murrah buffaloes sired by 95 bulls were used for the study. Farm had significant effect on FL305MY, while season and year of calving did not had significant effect in the present study. Breeding value for first lactation 305 days milk yield was estimated using contemporary comparison (CC) method. The breeding value of different bulls varied from 1582.08 kg in fifth set to 2058.11 kg in sixth set.
