Finishing bulls need increasingly large cubicles throughout their growth, and optimal cubicle dimensions may differ from those used for dairy cows. The space requirements of finishing bulls was investigated by observing standing-up anddown and standing-up movements in dairy cows when cubicle size varied from about 2·3 m to 2·5 m in length, and from about 1·1 m to 1·2 m in width. In cubicles measuring 229 cm long by 112 cm wide as opposed to larger cubicles measuring 274 cm long by 132 cm wide, dairy cows spent less time lying and more time standing with only the front hooves on the lying surface ( Tucker et al., 2004). On the other hand, if cubicles are too large, the lying surface may get dirty (Bickert, 1999; Tucker et al., 2004), which could adversely affect skin and udder health as well as milk quality in dairy cattle.There are different approaches to defining cubicle size for cattle. Firstly, there is the trial-and-error approach, in which cubicles are built to a size based on an intuitive understanding of how much space cattle need for lying, lying down and standing up. Secondly, several attempts have been made to
