项目摘要

The transducer, recording and transmission division which record physiological and behavioral information were fixed to the cattle. The simple system collecting the data recorded in recording and transmission division by the radio system was devised, when the breeder wanted to collect the data. The range of the radio wave was about 100m. 1) Number of steps as an index of activity and estrus, 2) number of jaw movements as an index of feeding and rumination, 3) body temperature as an index of health status and estrus, 4) attitude (standing and lying) as an index of resting condition were monitored continuously by the application of this system. This recording system was able to apply to collect physiological and behavioral information in grazing and housing cattle.On the other hand, heart rate variability (HRV) analysis was carried out using 24 hours electrocardiogram recorded in the Holstein lactation cattle and Japanese black cattle, and the method for estimating the autonomic nervous … More activity was examined, and the rearing management stress was estimated. As the result, it was thought that Holstein in tie-stall were sympathetic-predominant throughout the daytime and night time, and Japanese black cattle in the free barns were more parasympathetic-predominant than the Holstein cows. It was indicated that HF value related to the parasympathetic nervous activity and LF value related to the sympathetic nervous activity, and HRV analysis seemed to be useful as an effective and non-invasive method for estimating autonomic nervous function.And, though it is possible to predict the parturition day by changes of the body temperature, external genitalia and udder, it is difficult to estimate by the parturition time. Safety, non-invasive and convenient remote monitoring system for warning the onset of parturition was developed experimentally from the viewpoint of the labor saving management. It was confirmed that portable telephone rang in a few minutes from the onset of labor. Less

当饲养员想要收集数据时，设计了记录生理和行为信息的传感器、记录和传输部分，通过无线电系统收集记录和传输部分中记录的数据的简单系统。无线电波约为100m 1) 步数作为活动和发情的指标，2) 下颌运动的次数作为进食和反刍的指标，3) 体温作为健康状况和发情的指标， 4）姿态（站立和躺卧）作为休息状态的指标，通过该系统的应用进行连续监测。该记录系统能够用于收集放牧和圈养牛的生理和行为信息。另一方面，心率。使用荷斯坦泌乳牛和日本黑牛记录的24小时心电图进行变异性（HRV）分析，研究了估计自主神经活动的方法，并估计了饲养管理应激。被认为系带栏内的荷斯坦牛在白天和夜间均以交感神经为主，而自由牛舍中的日本黑牛比荷斯坦牛以副交感神经为主，这表明 HF 值与副交感神经活动有关。 LF值与交感神经活动相关，HRV分析似乎可以作为一种有效且非侵入性的评估自主神经功能的方法。并且，尽管可以通过身体的变化来预测分娩日期从省力管理的角度出发，实验性地开发了安全、非侵入性、便捷的临产预警远程监测系统。分娩开始后几分钟内电话就响了。
