Genetic parameters for production traits and somatic cell scores estimated with a multiple trait random regression model in Italian Holsteins



Genetic parameters for production traits and somatic cell scores estimated with a multiple trait random regression model in Italian Holsteins



Proceedings of the 7th World Congress on Genetics Applied to Livestock Production, Montpellier, France, August, 2002 Session 1: 1-4



Genetic parameters for production traits and somatic cell scores (SCS) were estimated for Italian Holstein Friesian using a test day multiple trait random regression model. Average heritabilities for production traits resulted to be in a range from 0.30 to 0.38, increasing with lactation number. The SCS heritabilities were 0.15, 0.19, and 0.25, for the three lactations.
