Abstract

In this investigation 13699 data related to milk production from 2716 Holstein first calving and daughter from 167 sire cows were analyzed based on RANDOM REGRESSION MODEL (RR/CF) and REML Method incomplete lactating (5-90 days) and (5-120 days) in correlations to complete lactating were 0.67 and 0.72, respectively with progress in complete 5-240 day was 0.91 the correlation value for lactating persistency trait for incomplete lactating period (5-150 days) were 0.68 and as increase in milk production period this value reaches to 0.91 for incomplete period (5-240 days). Also this correlation for two months milk production and lactating persistency were 0.88 and 0.59, respectively, and for one month milk production and lactating persistency reached higher than 0.90.
