Behavior of highly productive cows in the winterat loose housing box growing

Abstract

The purpose. To study features of behavior of highly productive cows in the winter at loose housing box growing in rooms of semiopen type. Methods. Behavior of cows was studied according to A. Bondar procedure. Temperature and relative humidity of the air in cowhouse was determined according to V. Balanin procedure. Results. It is determined that cows were in standing position in the winter more hours than in the summer (for 23,5%). Thus animal on the average 2,09 h a day stood on passage near feed table, and the rest of the time (2,33 h, or 52,7%) – in boxes with sandy litter or only with forelegs in boxes. Cows were active for 40,29%, and passive for 59,71% of time of a day. Conclusions. In the winter indexes of temperature and relative humidity of an air of the room of the facilitated type deflect from the optimum. That results, in comparison with the summer season, in increase of time on consumption of feedstuff up to 27,37% of a time of day, and duration of their standing to 4,42 hours and decrease of duration of repose of cows laying for 1,04 h.
