(image from Wikipedia) Guinea Pigs are raised throughout the world as meat production animal. They are fairly efficient, and have a lot of benefits. Let's take a look at how they compare to rabbits.
A smoker is a great cooking tool to have about the place. You can smoke all kinds of meat, including ham, bacon, ribs, rabbits and more. It is a slow form of cooking, but the taste is exquisite and permeates the meat.
You can substitute rabbit in any chicken recipe. However, it tends to dry out quicker than chicken, so be sure to cook it on a lower heat and covered if necessary.
Rabbit is an excellent meat. It is very similar to chicken in a lot of ways, but is easier to process and has more meat on the carcass. Plus rabbits are far easier and quicker to breed than chickens. Rabbit meat is an easy addition to a sustainable food production system.
Most of your meat processing for a pig will require no more than dividing the carcass into the various cuts of meat, like ribs, steaks, roasts, etc. However, for some products, you will need some more specialised processing.
Pigs are one of the best animals to have around the homestead. They can convert most organic garbage into quality meat. Once they are big enough, it will be time to harvest that meat.
