Rubber floors (TopFloors®) Your calves flourish in a comfortable and healthy stable. For that reason, we have introduced the rubber floor called TopFloors® in the calf sector. The rubber feels soft and warm and provides the calf more support and grip. The TopFloors® is better for the calf’s heels and joints and prevents knee problems and bald patches. In addition, the manure is drained away quicker into the pit because of the slightly curved rubber slats. This means less ammonia in the stable. In short: a floor with many advantages.
