I agree with both previous comments... Have you ever met any groupping of dairy cows inside of new, modern stables? There are more than 100 heat stress days a year in Hungary (considering dairy farming), and the past times we could observe groupping of cows in 30-40 years old barns only. The new generation of stables (12 m high roof, movable curtins on longside walls, fan and spray system, resting boxes etc.) had been introduced in 1999. Several companies are busy in building stables, and from 3 year groupping of cows has appeared in the new-style stables too. All the parameters of building seems to be correct, but groupping is continously exist on the heat-stress months. Have You any comments for solution?
