The data on production performance of HF × Girhalfbreds maintained at Research cum Development Project on Cattle (RCDP), Mahatma PhuleKrishiVidyapeeth, Rahuri district, Ahmednagar, (M.H) were utilized for present study. The least squares means of total milk yield (kg), lactation length (days), dry period (days) and peak milk yield (kg) were estimated by considering the effects of period of calving, season of calving and lactation order as non-genetic factors. Then data were corrected for significant non genetic factor effect and effect of THI was estimated. Then data were corrected for significant non genetic factor effect and effect of THI was estimated. The effect of factor period of calving was significant from MMY1 to MMY8 (P<0.01) while it was non significant in MMY 9 and MMY10; the effect of factor season of calving was not significant on MMY1 to MMY10; the effect of order of lactation was significant on MMY1 to MMY4 (P<0.01) while it was non significant on traits from MMY 5 to MMY 10.
