AB  - Genetic parameters for productive traits were estimated using data collected over a 10 years period (1995-2005) from the dairy herds of Holstein-Native crossbred Cows in the W. Azerbaijan province in Iran. Heritability for milk yield, Fat yield and Fat percentage were 0.26, 0.24 and 0.36, respectively and their repeatability were 0.55, 0.35 and 0.38, respectively. Fat yield and Fat percentage had medium repeatability estimates. It has been estimated that heritability of milk yield traits were moderate while repeatability of this trait was high. Thus, high repeatability estimates are promising opportunities for early selection practices.
