The influence of parity on milk let-down time in Mehsana buffaloes was investigated in a study. On the basis of parity (1-4 lactation), twenty-four Mehsana buffaloes were divided into four groups and kept in the same feeding and housing circumstances. For six months, data on letdown time for different parity buffaloes was collected at morning and evening milking six days a month. For the months of August, September, November, and January, the average letdown time was longer in the evening milking, whereas it was longer in the morning milking in the months of October and December, and the difference was not significant. Lactation-I (L1), Lactation-II (L2), Lactation-III (L3), and Lactation-IV (L4) letdown times were 71.15, 69.22, 62.30, and 56.65 seconds, respectively, with an overall average of 64.83 seconds. The variations between lactation were significant (P0.01). With increased parity, a decreasing trend in letdown time was seen. Morning milking took 65.58 seconds longer than evening milking (64.09 seconds), but the difference was not significant. It may be stated that as the parity of the Mehsana buffaloes increases, the average time required for letdown reduces. As a result, teat manipulation should be given to first-time calvers before to calving, and pre-milking udder stimulation should be included to the milking regimen.
