Abstract

Jaffarabadi buffalo is well known buffalo breed of India for their highest body weight and fat %. As the lactation milk yield is most important parameter of dairy buffalo, it affected by many genetic and non-genetic. During this study to see the effect of non-genetic factors on production records we were collected and analyze 77 complete lactations of Jaffarabadi buffaloes sired by 39 buffalo bulls. Non-genetics factors taken into consideration were; period of birth, season of birth, period of calving, season of calving, age at first calving and lactation length as fixed effect and sire as random effect on First Lactation Milk Yield (FLMY). R software version 9.3.3.0 was used to carry out the various analyses of data. The means of FLMY was found 1745.5±87.72 kg. Analysis revealed that lactation length, period of birth and period of calving were affecting FLMY significantly (P<0.05) while age at first calving, season of birth and season of calving to be found with non-significant effect (P>0.05). The Jaffarabadi buffaloes refreshing and born during winter season were found to be with high in FLMY as 1962.53±176.73 and 1991.87±179.47 kg., respectively. This buffalo breed was found as long day yielders based on lactation length data analysis.
