The first project in the UK to give real time data on heat stress in cows has been launched. With limited UK data available on the impact of heat stress in indoor and outdoor herds, Lallemand Animal Nutrition and Dr Tom Chamberlain, founder of Chalcombe Ltd, are launching the first ever UK based, real time trial to support farmers this summer. “The biggest issue facing UK farmers when it comes to heat stress is that our cows aren’t adapted for higher temperatures. Because of this, and the fact that most of the data we have comes from hot countries, the threshold could be significantly lower than what we currently think,” explained Mark McFarland, feed additive product manager at Lallemand Animal Nutrition.
