work or during warm weather from 85 to 110 pounds will be 
consumed. Mules in Oklahoma, during hot summer weather, 
consumed 113 pounds of water daily with a minimum of 107 
pounds and a maximum of 175.^ The ration was composed of 
grain and hay. 
Experiments conducted in the British Army showed that horses, 
when allowed to drink at will, consumed about one-fourth of 
their daily allowance in the morning, about three-eighths at noon 
and the remainder at night. 
European experiments indicate that the time of drinking has 
no appreciable effect on the digestibility of the food. Animals 
may be watered either before or after feeding with equally good 
results, but it is desirable to always observe the same practice 
since some animals do not feed well if watered after feeding, when 
they are accustomed to being watered before. However, animals 
should not be watered when they are hot, since it may induce 
colic or other similar ailments.
