Abstract
Based on 202 observations, the mean and standard errors values per milking for hind left, hind right, fore right and fore left quarters of lactating Iranian buffaloes were recorded, respectively as 1200±19, 1167±18, 533±16 and 496±16 g for milk yield; 7.21±0.09, 7.21±0.09, 7.11±0.08 and 7.11±0.08% for fat, 9.91±0.06, 9.93±0.05, 9.89±0.04 and 9.90±0.4% SNF; 620±13, 611±12, 509±11 and 491±11 g min-1 for milk flow rate and 122±4, 119±4, 70±3 and 69±3 sec for total milking time under hand milking conditions. The overall let down time was 94±2 sec. The differences between individual quarters between fore pair and hind pair quarters and between right pair and left pair quarters were not significant only for fat and SNF contest, while between the right pair and left pair quarters differences were not significant for any of the parameters. Parity and stage of lactation influenced all the quarter (individual, fore pair vs. hind pair, right pair vs. left pair) parameters with trends similar to those of the same parameters for the whole udder, the time of milking (am or pm) influenced significantly milk yield, rate of flow and SNF content only, which were higher in the morning.
