Effect of Air Temperature on Rumination Activity and Milk Production of Holstein Cows
Original language description
The aim of this study was to evaluate the effect of air temperature on rumination activity and milk production of Holstein cows. Monitoring took place at the University farm in Žabčice within 4 weeks with a lower (L.) - 11.3 oC and 4 weeks with a higher (H.) - 25.5 oC average daily temperature, in 2016. Two groups of cows - 75 animals each - were included into experiment. From both groups there were always randomly selected 10 lying and chewing cows. For these cows the length of rumination cycle (s), the number of masticatory movements (n), the intensity of rumination (n/s) and the daily milk yield (kg) were evaluated and recorded. We found a statistically significant difference in the length of ruminal cycle (L. 58.1; H.53.0), the number of ruminal movements (L. 65.9; H. 57.0) and the intensity of rumination (L. 0.88; H. 0.93). Daily milk yield values were not statistically significant (L. 37.4; H. 36.8).
