The impacts of global climate change, the subsequent negative impacts of heat stress and low commodity prices are becoming more pressing issues for the world’s tropical dairy cows and their farmers. Since 2006, New Zealand company Dairy Solutionz has been developing heat tolerant breeds for tropical pastoral farming systems. Roger Bourne speaks with chief executive of Dairy Solutionz, Derek Fairweather, about progress of the breeding programme that’s designed to produce a heat tolerant Bos Taurus dairy cow.
