Abstract
The lactation curve constants derived from gamma type model Y = A n b e-cn (Wood, 1967) expressed in logarithmic form fitted to 707 lactation records of dairy buffaloes maintained at two different military dairy farms in Pakistan, were subjected to least squares analysis. The constant a showed a significant effect of season of calving,lactation length (both P<0.01 land farm (P<0.001). Both constants (b and c) differed significantly for buffaloes calving in different seasons, with different lactation lengths (both P<0.001) and of different lactation numbers (P<0.05).
