Competing Interests

The study received combined funding from Beef+Lamb NZ and Meat and Livestock Australia, as well as additional funding from the Foundation for Research, Science and Technology. Furthermore, two authors were employed by AgResearch, a New Zealand crown research institute. The funding sources and author employment by AgResearch do not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
