MILK AS THE SOLE DIET OP RUMINANTS 



507 



The fact that milk can successfully act as the sole diet of 

 mammalia other than ruminants has been demonstrated by Mc- 

 Co'llum^ who was able to raise a sow to maturity on milk alune 

 and the sow also reproduced normally. 



EXPERIMENTAL WORK. 



In the work reported here two calves were used and they 

 were fed on milk alone from birth until the time of their death. 



TABLE II. 

 ANIMALS USED. 



Both calves were allowed to remain with their dams for a 

 few days after birth and were then put on a whole milk ration. 

 The amount of milk fed was limited to what the calves seemed 

 able to handle satisfactorily and though they might possibly have 

 become accustomed to large quantities it was deemed advisable 

 to keep their consumption of milk comparable to that of other 

 animals of similar weight in the herd and thus prevent diges- 

 tive troubles as far as possible. 



No roughage, grain, or water was offered to either of the 

 calves, and at first no salt was given but from the time Calf No. 

 355 was 70 days old a salt roll was kept in front of him at all 

 times and the same treatment was given Calf No. 366 from the 

 time he was 30 days old. 



The calves were kept in a pen bedded at first with shavings 

 and later with sand as they showed a tendency to eat the shav- 

 ings. ' 1 i 1
