[Hi Natures Harmony Readers. If you'd like to see my comments and the background for this fight, click here after you're done reading. The laws on what is legal to feed to pigs vary from state to state; Whey, a byproduct of cheese production, is a prohibited feed in Missouri, for instance. Tim feeds whey to his pigs. I feed fish to mine. Both are legal feeds in our respective states. Not sure what his point is. Fish is found in many animal feeds. Fish meal, fish cake, fish oil, or just plain fish. ]
I've been feeding a couple of hundred pounds of fish to the pigs every day for the last few days, and have found that they prefer salmon over other types of fish. They like skin-on fillets better than the skin-off. They'll dig through a pile of fish and eat all of the salmon before they eat any of the other types of fish.
Here's a typical serving size for 30 pigs. It's helpful that these 4oz portions were packed loose in the box. Slit the box open, dump the fillets, toss the box into a pile, next box.
Color and texture wise they're actually in pretty good shape, but most show sizes of freezer burn. Doesn't seem to cause the pigs any anxiety. They eat it all.
