In 1895-6 the Iowa Agricultural College fed steer 

 calves for fourteen months, during ten of which a 

 record was kept of all the food consumed. During the 

 second period the steers were fattened for market. 

 This particular experiment is cited because the animals 

 were young and all the conditions were favorable to 

 the maximum consumption of food in proportion to 

 live weight:

The largest amount of digestible nutrients fed daily 

 per animal at any time during this experiment was 

 about 17.5 Ibs., after the animals had reached an 

 average weight of 1,200 Ibs. or over. This would be 

 approximately 14.5 Ibs. digestible organic matter per 

 1,000 pounds live weight. 



These two experiments are instances of successful 

 feeding where the increase was rapid and very satis-
