Download Better estimation of national ewe and beef cow liveweights

This report set out to validate the ewe and beef cow data currently being used in the NZ methane inventory model by comparing this data with all other available information, including: reviewing NZ literature on cow and ewe liveweights, obtaining current data from NZ flocks and herds; comparing dressing out percentages from ewes and beef cows with the inventory model and determining whether timing of the liveweights reflect a true average given the seasonal variation.
