项目摘要

1. Measurement of the biological information on cattle in a barn.The automatic measuring system on the biological and behavioral information in cattle tethered in a conventional dairy barn was constructed. The each data measured were transferred to personal computers and stored in after every minutes. The items measured were as follows.(1)Biological parameters : heat production, vaginal temperature, heart rate, respiration rate.(2)Behavioral parameters : standing, lying, eating, ruminating, drinking.2. Effects of behavior on the biological parameters.Four pregnant Holstein heifers were measured for five consecutive days using the apparatus mentioned above and the results were summarized as follows.(1)The body temperature decreased after standing up and increased after lying down. Heat production increased soon after standing and began to fall within eight minutes after standing.(2)The heat production, body temperature and heart rate increased after feeding. After the commencement of rumination the heat production increased, whereas no other biological parameters changed.(3)The body temperature and heart rate decreased after drinking water.3. Data exchange through the personal computer network.It seemed most acceptable that using an electric mail system on the domestic commercial network services for long distance communication and the local bulletin board system(BBS)for short distance communications.In future, the Integrated services digital network(ISDN)will become more popular and the international data exchange service progressing on a commercial bases.

1.牛舍内牛的生物信息测量。构建了常规牛舍内拴牛的生物和行为信息自动测量系统。每分钟测量一次后，将测得的各项数据传输至个人计算机并存储。测量项目如下：(1)生物学参数：产热量、阴道温度、心率、呼吸频率。(2)行为参数：站立、躺卧、进食、反省、饮酒。对4头妊娠荷斯坦小母牛进行了连续5天的测量，结果表明：(1)站立后体温下降，躺下后体温升高。站立后即刻产热量增加，站立后8分钟内开始下降。(2)摄食后产热量、体温和心率增加。开始反省后，产热量增加，而其他生物学参数没有变化。(3)喝水后体温和心率下降。通过个人计算机网络进行数据交换。在国内商业网络上使用电子邮件系统进行长途通信，使用本地公告牌系统(BBS)进行短距离通信似乎是最可接受的。未来，综合业务数字网(ISDN)将更加普及，国际数据交换服务将在商业基础上进行。
