How much water should you give your cattle?

For healthy flock, water is supposed to be supplied ad lib (all the time); and animals will drink as per the body requirement. [Edward Kiplimo, Standard]

Happy New year. Thank you for helping us learn more on animal husbandry.

I have been an ardent reader since I started my farming venture some years back. I come from Kitui and water is scarce both for livestock and home use. While I endeavour to provide my sheep and two dairy cows with sufficient water, sometimes, I face challenges. That is why I am asking, is there a minimum daily water requirement for animals?
