This study examined the behaviour and claw health of dairy cows on two floor types: slatted and grooved concrete. Two groups of 12 cows were switched between floors after three weeks for a second three week period. Observations were conducted during the third week on each floor. There were no differences in the behaviour of the cows on each floor type, with the exception that cows on the grooved floors stood less with all four feet inside the cubicles. Claw health was also similar between floor types. Both floors were scrapped automatically, and cows were observed to stumble over the scrapper blade and developed foot lesions suggestive of trauma from the blade. The two floors types were both considered suitable for dairy cows, but the scrapping system which is essential to the grooved system, needs improvement.
