as the data will show. The results of the two studies are given in 

 Table 14. 



In regard to yellow corn feeding, it is seen that replacing 2 Ibs. 

 cottonseed meal and 4 Ibs. white corn by 6 Ibs. yellow corn had no 

 influence upon the color of the milk fat. If yellow corn has any value 

 as an aid in the production of yellow milk fat, it would certainly 

 have been evident in this experiment where the milk fat was prac- 

 tically colorless before feeding the yellow corn. This experiment 

 therefore gives conclusive proof of the negative value of yellow corn 

 in the pigmentation of milk fat. The reason for this will be discussed 

 more fully in the general discussion of the experiments.
