Thanks! I will be sure to watch the protein when I start raising them. I didn't raise the pig I rendered - I was given a side of it. Would protein level cause the stench? The meat didn't smell like typical, fresh pork and I know that it was processed correctly (it was done at the same time I was having a calf slaughtered).
I thought that perhaps it hadn't been finished properly? I think I recall that swine can get soft fat if they are feeding on acorns, etc too close to slaughter but it has been a lot of years so I may not be remembering correctly. What stands out in memory though is the smell - this particular beast was just downright rank. Given that it was a gilt, I know it wasn't boar taint... But after this experience, I'll definitely watch the protein levels - thank you for the warning!
Off topic - are you raising Duroc or ??? Do you have a preference for a particular breed or mix?
