Competing Interests

Here the authors state that Dairy Research Institute Ltd provided support in the form of providing research material, but did not have any additional role in the study design, data collection and analysis, decision to publish, or preparation of the manuscript. Furthermore, none of the funding bodies had any role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. The fact that the authors' work was funded by several funding bodies and one of the authors is employed by a commercial company does not alter the authors' adherence to PLOS ONE policies on sharing data and material.
