Abstract: A barn in which dairy animals can freely move about, lie down and eat includes a floor, a light-transmitting roof construction, and a wall construction. The floor consists for the greater part of a moisture absorbing, pourable layer which is able to collect moisture from manure and urine. This moisture is removed by means of solar heat and wind drying, and if this is not sufficient, by means of a floor heating. There is thus only required a very limited stationary sub-floor with a manure collecting device, i.e. only below the milking implement.

Abstract: Milk flow detecting method and device monitors a flow of milk in a milk line which is connected to a teat cup and which has an aeration opening, like in a milking device. For this purpose, the milk filling level is monitored in a measuring section of the line. If the variation therein is too little, the absence of a flow, or at least an inadequate flow, is established. If, additionally, a (sufficient) filling level is detected, it can be concluded that there is an obstructed aeration opening.
