genetic evaluation; MACE; yield and functional traits
Abstract :
[en] Objective of this study was to improve the estimation of survival breeding values using multiple-trait across country evaluation procedures to combine direct information with milk, fat and protein yields and functional traits: milk persistency, somatic cell count, fertility (male and female) and calving ease (direct and maternal). A set of bulls was selected from the Austrian Simmental population and their breeding values were deregressed. An Expectation-Maximization REML procedure based on the multiple-trait across country evaluation equations was used to compute genetic (co)variance components among all traits and to predict breeding values.
