The effect of brushing and grooming-device on the welfare and productivity in cattle on the background of genetic differences

研究了刷毛器对牛福利和生产力的影响。行为和生理数据表明，每天刷牙几分钟，持续大约十天，可以减轻牛对人的恐惧。然而，牛对刷毛的反应没有遗传差异。研究发现，牛持续使用毛刷1年多，自我梳理的主要部位是头部和颈部。在市场上因病理异常而排斥内脏器官的牛数量因安装整毛装置而减少。

The effects of brushing and grooming-device on the welfare and productivity in cattle were investigated. Behavioural and physiological data indicated that brushing a few minutes/day for about ten days attenuated the fear of the cattle to human. However, there was no genetic difference in the reaction to brushing in cattle. It was founded that the cattle continued to use the brush for more than 1 year and the main parts of self-grooming were their head and neck. The number of cattle of which the internal organs were rejected because of pathological abnormality in the market decreased by the installing grooming-device.
