In Latvia, use of unheated cow sheds with lowered environmental temperature is growing. In such circumstances, cooling of the milking equipment washing liquid is more rapid and quality of the washing equipment decreases. However, it may be eliminated by coating the milk and washing liquid piping with heat insulation. A mathematical model of the milking equipment washing liquid by which the end temperature of the washing liquid cooling can be determined is developed. Two types of heat insulation materials are under the trial. Laboratory experiments on cooling of the washing liquid are carried out and the experimental coefficients of the mathematical model are determined.

The productivity, health and welfare of cows are considerably influenced by the microclimate of the cowshed in which they live. The present paper deals with the spatial variation in temperature within uninsulated wooden cowshed and cowshed renovated from stanchions into cubicles. The type of the cowshed (uninsulated wooden cubicle cowshed and renovated cowshed made of concrete elements) influences spatial variation of indoor temperature. Greater spatial variation existed in renovated cowsheds, but these remained within the range of cows' temperature comfort zone.
