The aim of this work was to predict cow diet composition from FA concentrations of bulk milk collected in ten different EU countries. A dataset comprising 1248 bulk cow milk samples and corresponding information related to diet composition assessed by rapid farmer’s interviews was used. The prediction based on FA for cow diet composition were excellent for fresh herbage (R2 = 0.81), good for hay, intermediate for corn silage and grass silage (R2 > 0.62) and poor for concentrates (R2 < 0.51) proportions in cow diet. The prediction models we presented could offer a valuable tool to authenticate cow feeding.
Can we use the fatty acid composition of bulk milk to authenticate the diet composition?

Abstract
The aim of this work was to predict cow diet composition from FA concentrations of bulk milk collected in ten different EU countries. A dataset comprising 1248 bulk cow milk samples and corresponding information related to diet composition assessed by rapid farmer’s interviews was used. The prediction based on FA for cow diet composition were excellent for fresh herbage (R2 = 0.81), good for hay, intermediate for corn silage and grass silage (R2 > 0.62) and poor for concentrates (R2 < 0.51) proportions in cow diet. The prediction models we presented could offer a valuable tool to authenticate cow feeding.
