Data on 437 lactation records of Nili-Ravi buffalo maintained from 1978-93 at Livestock Experiment Station, University of Agriculture, Faisalabad were used to study the influence of various facrtors on persistency of lactation and peak milk yied. Persistency oflactation and peak milk yield averaged 91.31 ± 0.55 kg and 239.15 ± 7.74 kg, respectivley. This study showed that persistency and peak milk yield differed significantly in buffaloes calving in different years and seasons. Buffalo calvng during hot humid were more persistent (92.80 ± 0.52) thant he buffaloes calving in other seasons of the year. The highest peak milk yield (249.53 ± 8.10 kg) was obtained during hot dry months. The persistecy of lactation was significantly correlated with lenth og lactation. Lactation number had non-significant effect on presistency of lactation as well as on peak milk yield
