The additive & multiplicative Correction Factors (CFs)were developed for various systemic sources which affect the milk yield as age at calving (AAC),days open or service period (DOPN),days dry or dry period (DDRY) & lactation length (LL) by using 1648 lactation records of 491 crossbred cows generated under ALL INDIA CO-ORDINATED RESEARCH PROJECT (AICRP) on cattle at Jabalpur station. These CFs were used simultaneously to correct the milk yield & the effectiveness of the correction was judged by comparing the h2 ,r & residual variance (RV) of the uncorrected & the corrected 300 day milk yield.
