I am a 9 grader in FFA and I can get extra credit if I have the answer to this question!! Why do some cows produce yellow milk? I thought it might be because of the fat content but i wasn't sure. Thank You

Colour of milk

The colour is a blend of the individual effects produced by; 1) the colloidal casein particles and the dispersed fat globules, both of which scatter light, and 2) the carotene (to some extent xanthophyll) which imparts a yellowish tint. Milk ranges in colour from yellowish creamy white (cow milk) to creamy white (buffalo milk). The intensity of the yellow colour of cow milk depends on various factors such as breed, feeds, size of fat globules, fat percentage of milk etc.
