项目摘要

The goal of the research is "Training of eliminative behavior of cattle". We are challenging to decrease cattle defecation on deep litter in a loose housing barn. We tested the new standing detection device with FRID and the automatic feeding station (FS) which connected a PC to control cattle behavior.1.Development of new standing detection device with FRIDWe changed the sensor in the device to an inclination switch form a mercury switch that used in a former experiment. The all-in-one program for control whole devices in the system was almost completed up to a practical level.2.Experiment of cattle in group feeding.(1)Animals and facility : Three experiments were carried out in two years. Six Holstein heifers were grouped together in an experimental paddock in each experiment. A standing detection device was also attached to each heifer's left hind leg.(2)Exp.1 : The heifers were allowed to obtain the concentrate when they visited the FS within a limited time ( 60min, 30min, 10min, 5min ) after standing up. Results : The number of instance of defecation in bedding area decreased significantly (P<0.05) during FS was used. However, the effects of limited time were not cleared.(3)Exp.2 : Two limited time of 60min and 10min were compared. Results : The number of instance of defecation in bedding area decreased during the 60min period significantly (P<0.05) than the 10min period.(4)Exp.3 : Two treatments were compared. During the "One standing one feeding" period, the heifers were allowed to obtain the concentrate at the FS once at each standing. During the "Interval feeding" period, the heifers were allowed to obtain the concentrate at the FS once each 6h. Results : The number of instance of defecation in front of FS remarkably increased during "One standing one feeding" period then "Interval feeding" period.

该研究的目标是“牛的消除行为训练”。我们面临着减少牛在松散的畜舍谷仓深层垫料上排便的挑战。我们测试了带有FRID的新型站立检测装置和连接PC来控制牛行为的自动饲喂站（FS）。 1.带有FRID的新型站立检测装置的开发我们将装置中的传感器从以前实验中使用的水银开关改为倾斜开关。系统中控制全部设备的一体化程序已基本完成，达到实用水平。2、牛群饲养实验。(1)动物及设施：两年内进行了3次实验。在每个实验中，六头荷斯坦小母牛被分组在一个实验围场中。每只小母牛的左后腿上还安装了站立检测装置。(2)实验1：小母牛在站立后的有限时间内(60分钟、30分钟、10分钟、5分钟)访问FS时允许获得浓缩物。结果：使用FS期间，床上用品区域排便次数明显减少（P<0.05）。但限制时间的影响尚未明确。(3)实验2：比较60分钟和10分钟两种限制时间。结果：在60分钟期间，在被褥区域排便的次数比10分钟期间显着减少(P<0.05)。(4)实验3：比较两个处理。在“一站一饲”期间，小母牛每次站立时在FS处获得一次精料。在“间歇饲喂”期间，小母牛每 6 小时在 FS 获得一次精料。结果：在“一站一喂”期间，FS前面排便的次数显着增加，而“间隔喂”期间则显着增加。
