Feasibility of a genetic evaluation for milk fatty acids in dairy cattle ; Faisabilité d'une sélection génétique pour les acides gras du lait en Région Wallonne

peer reviewed ; Recent development of equations based on mid-infrared (MIR) spectrometry for the prediction of milk fatty acid (FA) contents allows their measurement on a large scale during performance recording. The objective was to show that a genetic evaluation for milk FA in dairy cattle is feasible in the Walloon region of Belgium and to report first results. Estimated breeding values (EBV) and associated reliabilities (REL) were computed using a multi-trait test-day animal model similar to the one used for the routine genetic evaluation for yield traits. Studied traits were first lactati... Mehr ...
