JUSTIFICATION OF THE BASIC PARAMETERS OF A DAIRY FARM FOR 500 COWS WITH ROBOTIC MILKING SYSTEMS

Abstract

The article highlights the results of research on the assessment of the conditions for keeping high-yielding cows in a new type of room with a width of 36 m and a height of 10.5 m according to indicators of the microclimate and daily behavior of cows. It has been established that the volume-planning and technological solutions of this room with robotic milking systems provide comfortable conditions for keeping highly productive cows. So, the air temperature and relative humidity of the room meet the existing standards. The presence of side curtains and a light-aeration comb ensure a high speed of air movement at the level of 0.65 m/s, which has a positive effect on its gassiness. The ammonia content is at the level of 2.9 mg/m3 against 20 mg/m3 according to regulations, and the level of hydrogen sulfide is 0.2 mg/m3 against 10.0 mg/m3, and the level of carbon dioxide is two times lower. Studying the behavior of cows under the conditions of a new type of room, it has been established that animals show the greatest activity during the change in daylight hours, and the least one - in the middle of the day or night. The behavior of cows under the conditions of the new technology changes depends on the productivity of the cows. Thus, as productivity increases, the duration of feed and water consumption and stay in the robotic box increases. Animals with the productivity of 20 kg stand for 13 hours and lie down for 11 hours, while cows with the productivity of 40 kg stand for only 10 hours and lie for 14 hours, which corresponds to their physiological needs. Based on the obtained research results, we have justified the main parameters of a new type of premises with robotic milking systems for 500 cows.
