Whilst composting might seem to resolve the problem of over supply or diseased stock I am wondering where this compost will end up, in bags sold to home gardeners, spread in bulk over pastures or market gardens?
This leaves some serious questions that need to be addressed, given these animals are fed growth hormones along with antibiotics and heaps of other drugs, some of which will not be effected or broken down in the composting process, then there is the extreme danger of humans contracting Brucilosis ("I think that's the right spelling"), from coming in contact with this compost , Blood and bone has clear warnings on the bags in Australia at least, any one that has worked in slaughter yards or rendering plants can tell you just how debilitating it can be, there are other infections equally as bad that can slowly and painfully kill you from coming in contact with decomposed animal parts.
Yes they can be disinfected or masked with more chemicals that will all doubtlessly end up in the food chain.
This Corona Virus certainly has changed or effected us all in unimaginable ways, who would have predicted otherwise healthy hogs would become Corona victims.
My Honest opinion to the composting of live stock on mass is that it's a huge Biological time bomb.
