THE REGIME OF COWSHED ENVIRONMENT AND GROUND SOILS TEMPERATURE

Abstract

The quantity and quality of milk depends not only on milking or milk storage equipment but also on cow's well-being. A cow lying on the animal bed gives a certain amount of heat, as intense heat exchanges occur on the ground through the floor. When lying, the blood in the cow’s udder flows more intensely. It is known that for the formation of one liter of milk 500 liters of blood should flow through the cow’s udder. The amount of milk is highly dependent from the micro-climate of the animal’s bed, during the rest of the cow. The poorly installed or inappropriately designed bearing bed’s floors do not meet the physiological needs of the animals from a thermal point of view, much more energy loss occurs. Often there are cases where cold-frozen animals suffer from various cold diseases and their productivity decreases. Therefore, no less attention should be paid to the cow’s bed floor.
The article analyses the temperature regime of the base of the cowshed and the ground of its environment during the regular period. The structure of the cowshed building is energy-heated, with bearing vault structures. Cows are kept tied up in re-bars. The floor of the cowshed room is installed on the ground. The ground floor temperature is fixed in 3 boreholes under the floor and also in 3 wells near the cowshed ground. Temperatures were fixed up to 6 meters deep. The fields of distribution of the base of the cowshed and its ground temperature are established during the regular period.
Analysis of the temperature of the base of the cowshed and its environment showed that the ground temperature is influenced by the amount of heat released by the animal, which transmits itself not only to the room, but also to the base ground through the floor of the bearing bed. Since the bed’s floor is installed on the ground, the amount of heat loss caused by the animal through the floor depends not only on the thermal properties of the floor, but also on the base ground temperature regime. Extremely intense heat exchanges through the base ground occur during the coldest period of the year.
