Abstract

Records of milk production and pedigree information of Mahdasht dairy herd from 1994 to 1998 were used to survey the factors that influence economic traits and evaluated environmental factors and genetic parameters. Respectively. The total milk yield, peak production, days in milk, days open and calving interval were 6782±1006(kg), 32±6(kg), 290±31 (day), 121±52 (day) and 390±46 (day), respectively. The total milk yield, days in milk and calving interval were affected by days open (P<0.05). The best days open was 80 to 110 days. The effects of year and month of calving were significant on days open (P<0.05). The Heritability of days open was 0.06±0.03. The additive genetic correlation of days open with total milk yield, peak production, day in milk and calving interval were 0.19, 0.1, 0.13 and 0.87 and phenotypic correlation were 0.08, 0.3, 0.1 and 0.66, respectively.
