Cows should be able to rest as much and as often as they want. The cow's lying time is at least twelve hours a day, fourteen hours is optimal. This requires a comfortable and dry stall where she can lie down and stand up without any problems. Proper dimensions lead to cows lying straight, so that the manure ends up in the manure alley and the cubicle remains hygienic and dry. Cow lying comfort is determined by a combination of the right freestall divider, the right matting and proper dimensioning.
