Farm systems that use a feed-pad for delivering mixed-rations to dairy cows are becoming more common in countries with primarily pasture-based dairy systems, such as Australia. However, feeding a ration on a feed-pad may alter cows' key daily behaviours such as grazing, ruminating and resting, due to extended time off-pasture. The objective of this study was to compare the time budget of multiparous grazing cows fed partial mixed-rations (PMR) on a feed-pad with that of cows fed supplements during milking and in the paddock (Control). A total of 16 groups of early-lactation, Holstein-Friesian dairy cows consisting of eight cows per group were randomly assigned to each of two dietary treatmen..
