LOL, Of course I know better---you are in the middle of winter.

Usually dairy cattle are sequestered and kept housed, close to their feed. Few get out on grass now. High production has been the push for years, and that means lots of grain, as well as hay or silage. The butter and cream are a better quality the more the girls get on grass.....

Diet coke here usually has aspartame. Doesnt come with splenda. I can taste the difference. Coke now has MANY forumulations.

Also, a trick in baking is to use several different sweeteners. By blending several , they seem to nutralize each other and just leaves the sweet.
