Abstract

Different milk products require milk of different composition for their optimal processing and production. Selection has been proposed as a method to alter the composition of milk to meet these optimal processing requirements through breeding. By applying a milk processing sector model to data on 5,797 mixed breed animals, estimated milk product yields for whole milk powder, skim milk powder, butter and cheese were produced. Estimated breeding values (EBVs) for these milk products can be used directly in index rankings, creating a greater flexibility in breeding programs than currently exists. Keywords: milk products, breeding values, dairy, New Zealand
