>>1367437I've looked into some of those oddball breeds of cattle and the big downside is you pay by the pound (on the hoof) to ship them out to be butchered so you're potentially spending a few hundred bucks extra for the weight of the fur on those longhairs.
As far as dairy that's an awful big commitment. Though someone up the street does a great business with goats (cheese and milk) and uses the whey and other waste to fatten up half a dozen hogs. Turning excess milk or milk byproducts into pork seems a good way to go.
Also, rate my cock.
