Thanks to grooming in cattle, dirt, dust and parasites that are removed, skin blood circulation is increased and muscles are massaged. However, grooming should be done with appropriate tools and equipment. Otherwise, it can be more damaging than benefit. There would be a risk that can hurt the animal's life if not paid attention, and may result in injury or even tail rupture. Animals exposed to such situations normally want to escape from grooming and show resistance even though they enjoy it very much. Inaccurate applications during the acclimatization period, the use of small and low-placed brushes that are not suitable for the size and structure of the cattle, malfunctions during the operation of the grooming brush and in the event of incorrect operation, the wounds occurring in different parts of the body can prevent the expected benefit from the use of the grooming brush. But many works carry on this subject to provide more efficient grooming instruments for cow comfort. And grooming is considered a potential indicator of positive welfare. The combination and integration of welfare instruments will ensure optimum wellbeing for dairy animals to maximize profitability. Use of welfare instruments combined with new technologies for information handling and integration to instruments give more effective results.
