I measured the pigs last night with the string/measuring tape method. I found it a while ago (and have tried it a few times) at Sugar Mountain Farm’s site (which has a wealth of info on pasture raised pigs). The basic formula is (LxGxG)/400. This is done in inches. My Old Spot pig (Spanky) happened to be the same length as girth- 28.5 inches. So (28.5Lx28.5Gx28.5G)/400= 23,149/400= 57.87 lbs. Our big pig (Chester) taped to be 110 pounds (37Lx34.5Gx34.5G)/400= 44,039/400=110.09 lbs)
I’ve been feeding hog feed and scraps in the am and scratch grains/whole corn from the crock pot in the evenings. I’m moving the pig tractor about once a day. I’d been soaking the scratch grains/corn in HOT water for 24 hours, but wasn’t getting as good of digestion as I’d hoped- lots of grains still coming through unused. So now I use a crock pot on high for a couple hours between feeding and bedtime, then sitting off until the next day (or if I forget to get out fresh grain to throw in the crackpot, on low overnight, then sitting till evening feeding). I think it’s been working much better for me, although it takes a bit of electricity.
I’ll mention a crazy idea, just in case someone else wants to give it a try. I contemplated the idea of raising some meat rabbits to feed the pigs. I don’t think we’d eat rabbit much, but if I were going to keep pigs year round, I’d consider it still. IF I did, I’d probably not feed raw, although I believe I could. Mentally, I don’t like the idea as much, and the possible issue of disease transmission is greater then. It would be a bit more work, but I’d probably throw the killed rabbit in it’s entirety (skin, fur, bones, entrails, blood) in a pot of water and cook it OUTSIDE (very well to soften the bones) and feed. I don’t have room to plan on much extra for milk or eggs to feed pigs, but could probably squeeze in space for a few forage based rabbits to raise in the nicer weather and just overwinter a couple of breeding pairs. On the other hand, it might completely gross me out. If you’ve done it or ever give it a try, let me know!
