Bulletin 269, 



Detailed record of Lot A 



The calves in Lot A were older than the others at the beginning of 

 the experiment, and had been fed whole milk for three or four weeks 

 after birth and then gradually changed to skimmed milk. The amount 

 of skimmed milk was increased as the calves seemed to demand, until 

 22 pounds per day was being fed, half in the morning and half in the 

 evening. This milk was warmed to 90° F. when fed. 



The calves in Lot A grew very well and were not troubled with any 

 digestive disorders. The detailed record of feed for Lot A is given in 



Fig. 1 19. — Lot A at average age of 5 months. Average weight 370 pounds.

 The total gain for each 30-day period and the average gain per day for
