Im interested to try these out. there are some farms in the US which do offer things like buffalo milk, sheeps milk, and camel milk but they are harder to find. horses milk is very tough even though most farms have horses. apparently they dont like giving their milk to humans. reindeer and yak milk is almost impossible to find and im not sure if there are even any yaks in the US. these milks are supposedly very popular in parts of Asia and Russia. apparently the yaks milk naturally has some blood in it which gives it a pink tint. im also curious how they compare nutritionally and healthwise to cows and goats milk.
