96 Feeds and Feeding. 



and one-half honrs later. Another calf was maintained from 

 June until September upon milk and mixed grains. By the latter 

 date it evinced no desire for feed and would not rise. Later it 

 suddenly died. 



It was observed in these trials that although enormous quantities 

 of milk or milk and grain were consumed, there was no fat on the 

 carcass or about the kidneys of the calf that died. The muscles, 

 instead of being shrunken, were plump but exceedingly dense 

 and rigid to the touch. 



128. Conclusions. — The investigations of Davenport show that 

 the quantity of food consumed by an animal is not necessarily an 

 indication of its economic use, enormous amounts being taken by 

 these calves in the vain effort to satisfy an abnormal appetite. 

 Under this form of starvation, for such it was, even with the 

 liberal supply of the particular food given, there was observed 

 ''a ravenous appetite followed by enlargement and stiffening of 

 the joints, spells of dizziness and difficult locomotion, all followed 

 by periods of relief, and finally by a settled feeling of indiffer- 

 ence to food." 



From these several trials it is evident that mature ruminants 

 can be maintained for a considerable period upon a limited 

 amount of ground grain, and if liberally supplied therewith 

 they may even gain in weight. With young animals the demand 

 of nature seems more imperative, and it appears that calves can- 

 not be brought to maturity upon grain and milk, either singly or 

 combined, as the sole feed, but must have some coarse forage, 

 without which rumination is impossible.
