62 FEEDS AND FEEDING, ABRIDGED 



administration of feed and water should be uniform in time and 

 manner. Animals soon learn the feeding hour, and as it approaches 

 the secretions pour from the various digestive glands in anticipation of 

 the coming meal. Changes should be made gradually and only for 

 good reason, for in all feeding operations a changing period is usually 

 a losing one.
