The first basic need of the animal and our lack of understanding of it
Water intake depends on animal age, animal weight, dry matter/feed intake, body condition, milk production and heat intensity. Based on the same factors, if the animal is fed i.e. not tied, it drinks water 7 to 12 times, yes, 7 to 12 times in 24 hours according to its own will and physical needs. (Three, not four 3-4 times a day!!!)
