Drinking Activity of Calves on ad lib Feeding
 
 Interesting facts on standing and drinking.
See below. In this trial the ad lib calves (N=9) drank 54% of their total day's food between 6am and 8am and 44% between 4:00pm and 6:00pm. In an additional trial with ad lib feeding of acidified milk replacer these calves (N=22) had a similar drinking pattern with highly concentrated feeding behaviors. Was this drinking behavior stimulated by worker activity in the barn feeding the control calves? Does anyone know of similar information on drinking behavior of calves fed 24/7 ad lib?
