The SimHerd Crossbred simulation software is developed for assessing the economic consequences related to introduction of different systematic crossbreeding program at herd level given herd specific assumptions. Given average Danish Holstein management assumptions the results show that both two breed, and three breed rotational cross breeding systems, as well as Combi-Cross using Danish Red and Jersey are economically competitive with regard to net return per kg ECM. The competitiveness is due to increased levels for the functional traits as the yield level for all systems are equal or lower than the Holstein breed level.
