We are having rouble with our SCC in our tank and so are having to keep out milk that is otherwise fine. We can't drink that much and don't have calves to feed it to and our cats can only consume so much, so we were considering getting some pigs to feed it to. Do they need grain or other food besides milk? Is there an age where a majorly milk diet would be good for them, with little to no grain? Thanks for any input. We are assuming they would need some grain and if that is the case then we are better off just pouring the milk into the manure spreader.
