Following an all-too-quick trip home for a few weeks, I returned to a warm late summer in mid-Canterbury. It was around 2°C when I flew out of Dublin Airport, and three flights later, I landed in Christchurch to 28°C.On my arrival back, I called in with our scanner who was doing a final scan of some ‘doubtful’ cows. As we scan slightly early to allow us to get cows off the farm, we do a second scan a few weeks later to determine the true empty rate.
