To test the advantages of softer flooring in tie stalls, we compared the behavior and injuries of dairy cows housed in tie stalls with either soft rubber mats (n = 12) or concrete flooring (n = 12), both lightly covered with straw. Data were collected for 112 d beginning at 14 DIM (±4 d). Cows’ general activity was observed continuously for 24 h every 28 d. Behavior was also scored by a scan sampling technique every 14 d such that each cow was observed for a period of 3 min every 12 min. We scored the occurrence of leg lesions and other injuries every 7 d throughout the study. Cows on rubber mats had shorter bouts of lying but the frequency of bouts was higher, leading them to tend to spend more time lying compared with cows housed on concrete. Cows on concrete spent more time standing idle, but there was no difference in the time spent eating. There was no effect of stall flooring on the number of minor abrasions to the legs and body. There was a significantly higher incidence of swelling of the carpus joints for cows housed on concrete. Cows housed on soft rubber flooring appeared to be less hesitant to change posture from lying to standing (and vice versa), and as a result changed posture more frequently and spent more time lying than cows on concrete flooring. The decreased incidence of swelling of the carpus joint for cows on soft rubber mats may have important long-term effects in preventing a variety of leg problems.
