The answer to this question is usually a series of questions about the animal's liveweight, size, activity, and physiological state (pregnant, lactating, etc) - all of which affect daily intake. Then of course there is the ambient temperature and humidity of the farm and the amount of shade on offer.  So all this makes you realise how dangerous an "average" figure is. But you need some kind of figure for planning water supply systems, so here are some that have been around for years.  However, always err on the high side of any figures if you know that stock is having to deal with extra challenges like dairy cows walking long distances, stock in summer with no shade, or in winter when eating very wet herbage.
