The authors are grateful to K. Rentsch, S. Burch, J. Hollier, and M. Brophy [Department of Environment and Primary Industries (DEPT), Horsham, Victoria, Australia], and DemoDAIRY (Terang, Victoria, Australia) farm staff for technical assistance. Analysis of milk and herbage fatty acids and milk protein fractions were undertaken at AgResearch (Ruakura Research Centre, Hamilton, New Zealand). Herbage and supplement samples were analyzed for nutritive value using NIRS at DEPT. This research was funded by the Victorian DEPT and Dairy Australia (Melbourne, Victoria, Australia).
