| Outline of Final Research Achievements |
We recorded a sleep posture in dairy cows using the motion analysis and accelerometer for saving the time to measure it. The data from the motion analysis being modified by the visually recording cow’s standing and ruminating are useful for recording the total duration of sleep postures in dairy cows. Using an accelerometer, adequate measurements of one sleep posture (cows’ neck relaxed and their head against their flank in a lying position) can be made. Analyzing the relationships among sleep posture, cows’ welfare and productivity, sleep posture durations decreased in summer when cows would be affected by heat stress but there was no correlation between the data of sleep posture and milk yield.
