As part of a UK Government-funded project, Galebreaker compared cows cooled using VentTube Cool against cows with no cooling system during extreme summer temperatures — and the results were significant.
✔️ Non-cooled cows lost an average of 50 litres of milk per cow during the heat event
✔️ Cows with VentTube Cool maintained far more stable milk yields
✔️ Recovery to normal lying behaviour took 29 days without cooling — compared to just 2 days with VentTube Cool
✔️ Peak-lactation cows without cooling experienced up to a 79% reduction in lying time
The trial highlighted just how important effective ventilation and cooling can be for protecting cow comfort, welfare and productivity during periods of heat stress.
VentTube Cool delivers fresh air evenly throughout the building, helping more cows stay cooler and more comfortable when temperatures rise.
