CAROTIN, THE PRINCIPAL YELLOW PIGMENT OF MILK FAT 375 



TABLE No. 15. EFFECT OF A NON-PIGMENTED RATION AND OF A RATION CON- 



TAINING CARROTS UPON THE COLOR OF MILK FAT. 



HOLSTEIN Cow No. 221. 



(a) The hay was a mixture of equal parts of light colored timothy and 

 bleached alfalfa. 



Experiment No. 6 



This was a feeding experiment the results of which were ex- 

 pected to corroborate those of Experiment i, and show that the colon 

 of the milk fat of Jersey cows is as much dependent on the food as 

 those of other breeds. The variation in the feed and the resulting 

 color of the milk fat is shown in Table 16. A pure bred Jersey cow, 

 No. 59, was used for this experiment.
