The effect of a compressed air stimulus on blocking times in a concentrate feeding station for horses in group housing

It was observed that the average daily blocking durations, as well as the average daily blocking frequencies of the horses, could be reduced significantly by the application of compressed air. However, an increase of the observed blocking durations and blocking frequencies during the six weeks of the trial period indicates the occurrence of a habituation effect over time. In the course of the present study it became obvious that there are great individual differences concerning the reaction of the horses to the applied stimulation devices. As the emergence of blocking times is a very complex issue, the authors strongly recommend further scientific research on this topic. Possible future research focuses are discussed in the course of the present study.
