how much does a cow drink in hot weather
Hot season strategies How much water do cows need in hot weather? Allow for 200 - 250 litres per cow per day in hot weather - double what cows usually need each day. Make sure cows have access to plenty of cool drinking water wherever they are during the day. A big water trough on the exit side of the dairy is a must. Provide a minimum of 0.75m water trough space per cow at your feed-out facility. Water pipes should be 75mm in diameter, with suddicient pressure to provide 20 litres per cow per hour, so that troughs cope with periods of peak demand.
