Study on Behavioral Control of Eliminating Spot on Cattle Using a Computer Controlled Feeding Station

2001年研制了检测牛站立动作的装置和将检测到的站立信号发送到计算机的无线电发射系统。1.1)装置中采用四个水银开关检测牛站立动作。2)后小腿为合适的附着位置。3)检测的小马驹发生在奶牛抓头和走路时，设备不规则地弯曲。4)我们开发了一个程序，在这个程序中，只有奶牛连续10分钟的躺姿后才会出现站立信号，这是一个真正的站立动作。实际情境实验，训练奶牛在进行站立动作后移动到计算机控制的喂食站。视频记录用于确定笔中的淘汰点。1)单笔由两部分组成。一部分是床区，在床上撒上木屑，另一部分是喂料区，在喂料站设置。2)选用5头干奶牛。站立检测装置安装在动物的左后腿上。3)一期分为预备期、培训期、志愿访视期三个阶段。结果与讨论1)奶牛站姿检出率约为90%。这个结果我们完全可以接受。2)结果表明，奶牛站后有一定的可训练性。3)使用该系统可以降低床上的消除频率。4)奶牛学习速度的个性差异较大。这些结果表明，未来应该开发更有效的训练方法。

The device for detecting stand up action on cattle and the radio transmitting system for sending the detected standing signal to a computer were developed in 2001.1) Four mercury switch in the device were used for detecting standing action on cattle.2) The hind lower legs were suitable positions for attaching the device.3) The foals of detection were occurred when a cow scratched her head and while walking during which the devices were irregularly snaked.4) We developed the program in which the standing signal only after the succession of 10 minutes of lying position in cows should be accepted as a real standing action.The experiment of practical situation in which the cow was trained to move to the feeding station controlled by computer just after standing action were undertaken. The video recording was used to confirm the elimination spots in a pen.1) The single pen consisted of two parts were used. One part was a bed area where wood dust were applied and another was a feeding area where a feeding station was set.2) Five dry cows were used. The standing detection device were attached on the left hind leg of the animals.3) The one session were consisted of three period named preliminary periods, training periods, voluntary visiting periods.Results and discussion1) The rate of correct detection of standing up of cows was about 90%. This result was well acceptable for us.2) The results showed a trainability of cow to visit a feeding station just after standing.3) The reduction of elimination frequencies on beds were firmly expected using this system.4) The individuality of learning speed of cows were considerably varied. These results showed that the more effective training methods should developed in the future.
