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

将记录牛生理和行为信息的传感器、记录和传输装置固定在牛身上。当饲养员需要采集数据时，设计了一个简单的系统来收集无线电系统在记录和传输部门记录的数据。无线电波范围约为100m，应用该系统连续监测1)活动和发情指标步数，2)进食和反刍指标颌部运动次数，3)健康状态和发情指标体温，4)休息状态指标姿态（站立和躺卧）。该记录系统可用于收集放牧和圈养牛的生理和行为信息。另一方面，利用荷斯坦乳牛和日本黑牛的24 h心电图进行心率变异性（HRV）分析，并采用自主神经活动的估计方法，对饲养管理应激进行估计。因此，我们认为拴栏黑牛在白天和夜间都以交感神经为主，而自由栏黑牛的副交感神经为主。结果表明，HF值与副交感神经活动有关，LF值与交感神经活动有关，HRV分析可作为一种有效且无创的评估自主神经功能的方法。而且，虽然可以通过体温、外生殖器和乳房的变化来预测分娩日期，但很难通过分娩时间来估计。从省力管理的角度出发，实验性开发了安全、无创、便捷的分娩预警远程监控系统。经证实，便携式电话在分娩开始的几分钟内响了起来。少
