Until relatively recently, the welfare of the dairy cow was not often perceived as being poor. However, the dairy industry has been changing, and increasing attention has been paid by the general public to the animals’ welfare. Nowadays the consumer demands food from animals that are kept under conditions which allow them to function more or less naturally, and which provide shade and shelter [1]. It is now generally accepted that the animal husbandman has a responsibility to the animals under his care and to society in general in order to maintain an acceptable standard of humane care of animals. In the Northern Hemisphere, where most dairy cows are housed indoors either permanently or at least during a significant part of the year, there are industry standards or codes that pay specific attention to the animals’ comfort. In general, they are housed in either straw yards or comfortable barns, where they have access to properly designed cubicle stalls that have the correct dimensions [2-4].
