That's a low price on a hog, although it's difficult to compare price based on different parts of the country. One think you might want to consider is total out of pocket you want to spend to have all that food at your ready. A side of beef could weigh maybe 350-400 lbs where as a side of pork could be 75-150lbs, so the pork will be less than half of the beef. However, I believe a side of beef will aslo last maybe twice as long (meaning before getting freezer burn) in the freezer than a side of pork, so that something to think about to. Don't forget that you're looking at hanging weight, what do they charge to process it and dispose of the carcass? Also, if it were me, I'd ask that the beef be grain feed for the last 60 days. I think you can taste a big difference between grain fed and grass fed beef and in my opinion grain fed is better. Lastly, which one do you like to eat more often?
This is just one man's opinion. Really, either way you can't lose! You'll have a freezer full of meat! Happy desicion making.
