Hair length was recorded for Holstein cows in two seasons (spring and fall) and related to milk production. Variance components were estimated by Restricted Maximum Likelihood Method under Animal Model, using the DFREML algorithm. Heritabilities for hair length and milk production were 0.20 and 0.26, respectively. Genetic, phenotypic, and environmental correlations between hair length and milk production were - 0.56; -0.19 and -0.02, respectively. Sire breeding values ranged from -1.68 to 1.25 for hair length and -1273.06 to 800.81 kg for milk production. Correlations between sire breeding values for milk production and hair length was negative and non significant.
