The present study was undertaken to assess production performance traits of Sahiwal cows, maintained at the Bull Mother Experimental Farm, Anjora, Durg (Chhattisgarh). The objectives were to evaluate the effect of various non-genetic and genetic factors on some important production traits generated during the 9 years (from 2001 to 2009). The selected traits considered were Total Lactation Yield (TLY) and Lactation Length (LL). The overall least squares means for TLY and LL were found registered as 1322.135±33.141 kg and 293.294±3.416 days, respectively. The analysis of variance revealed that season had no effect on TLY and LL. The period effect was found to be highly significant (P<0.01) for TLY and LL whereas the effect of parity was found non-significant for both traits. The sire effect was found to be non-significant for all traits. The TLY increased from period 1st to 3rd period. The results indicated gradual improvement of milk yield from 2001 to 2009 in Sahiwal cows and remained similar during different seasons and among different parities. The progenies of different sires had also similar productive performances.
