“could you ask your Rav if he is aware that powdered milk is made today from camels’ and horses’ milk”
The only milk products that can be legally sold in the US today are from cows, sheep, and goats. There is a serious effort to legalize the sale of products from camel milk (if you own a camel farm you can produce it yourself and some Amish do that), and there was a news article last year of a human woman who made cheese from her breast milk.
