I wouldn't know. That said, commercial diary farms usually only deal with one species.
You don't have to worry about cross contamination lol commercial dairy farms are typically one-species enterprises.
Do you know anything about dairy farming? What I know about dairy farming is that is a type of agriculture that involves the long-term production of milk. That sounds interesting! I always wondered how butter was made and why humans drink another animals milk! I don't know the answer, however goats, sheep and camels have been used in dairy farming. Oh yeah I forgot about all those, I suppose they would be present on a dairy farm as well! Ive used lotion made from goat milk! and goat cheese is gross tasting Oh yeah? It turns out donkey dairies are becoming more popular in Italy because people use donkey milk for infants. Donkey. Milk. I wonder what in tarnation that tastes like!!
Although any mammal can produce milk, commercial dairy farms are typically one-species enterprises.
