Indian corn than with wheat. The low price of wheat in the last few 

 years has, however, directed a considerable amount of attention to the 

 use of that cereal instead of Indian corn in the feeding of animals. 

 The data which have been obtained in this country, secured from com- 

 parative feeding experiments, are not always uniform. In some 

 instances it has been found that, pound for pound, wheat gave a 

 slightly better result in feeding animals than Indian corn, while in 

 others the preference is given by the experimenter to Indian corn. In 

 experiments made at the South Dakota station (Bulletin 38) pigs were 

 fed with different cereals, among others with ground Indian corn and 

 ground wheat. The comparative results obtained are as follows: 



Summarized results of experiments with pigs. 



In the data obtained in this experiment the Indian corn, pound for 

 pound, was found to give the better results in every respect. 



COMPARATIVE ASSIMILATION OF WHEAT AND MAIZE. 



The comparative digestibility of wheat and Indian corn has been 

 studied in the Minnesota station (Bulletin No. 36). The data obtained, 

 with the exception of the digestibility of the ash, are as follows : 



Digestion coefficients of ivheat and other grains. 



From these data it is seen that the wheat was slightly less digestible 

 than the Indian corn. From a study of the data at the Minnesota station 

 it maybe stated that when corn and wheat are both selling at 50 cents 

 per bushel, the 50 cents will purchase the same amount of digestible 

 dry matter in both instances. In the case of wheat, however, the pur- 

 chaser will obtain 2 pounds more of digestible protein, and in the case of 

 Indian corn 2 pounds more of digestible carbohydrates. The quantity 

 of heat generated by the food in each case is almost exactly the same. 

 The result of these experiments, therefore, is to establish with certainty 

 that the digestible coefficient of Indian corn is not inferior, but, if there
