Research project First aid for cows experiencing heat stress

General introduction

For beef cattle and dairy farmers, the EHBKOE research project has provided concrete tools for controlling heat stress in animals. Farm managers now have access to a cost-benefit analysis for the measures that can be taken. Substantiated advice on fan placement and practical materials such as videos and a decision tree are all available. This project was prompted by the increasing number of hot days in Flanders during the summer and the need for effective, feasible measures.

Research approach

We worked on five themes: silage and feed management, grazing strategies, fans, misting, and roof cooling. Both operating costs and potential investment costs were analyzed. The impact of fan control and operation on the cooling effect in cows was investigated experimentally and then used in simulations for model barns to advise on placement and installation. Within feed management, the influence of heat inhibitors—additives that slow down unwanted heating of roughage—on feed quality and feed intake was evaluated.

Relevance/Valorization

Important steps have been taken to support Flemish beef and dairy farmers in choosing and correctly applying preventive and remedial techniques, both new solutions and improved implementation of known practices. The results have been compiled in informative videos on the Rundveeloket YouTube channel: an introduction and separate videos on feed management, ventilation, and cooling with water techniques. Two demonstration fairs provided an accessible discussion and learning platform for cattle farmers. A decision tree helps companies select the most appropriate measures. This demonstration project was funded by the Flemish government and the European Agricultural Fund for Rural Development (EAFRD).
