I raise them currently, so I will give you some of my tips
1) Breed -- the usual are NZW, champagne, Californians, and Flemish Giants....the upside to the Flemish is that they can grow to be VERY large, up to 12 to 14 pounds mature. At about 8 weeks they are 6 pounds or so. The downside is they take a TON of food, and the real feed to bone ratio is not all that good because of this. In contrast the NZW are smaller, grow about the same speed, and have likely the best feed to meat ratio.
2) Climate -- I am currently raising Silver Foxes, a breed that are known for their extreme cold tolerance. I live in a cold climate, and I have found that a few of the other varieties hardly grow at all over the winter due to the cold. They are using all their nutrients to stay warm, instead of meat for me Consider Californians if you live somewhere warm, as on the whole rabbits are better in cold that heat.
3) Feed -- Buying rabbit food isn't expensive per pound, but it will add up if you have a large brood, and esp if you raise Giants. I recommend, if you want big rabbits or to save money, that you make a little enclosure for them to stay in to forage pasture. The meat will taste better, be healthier, and save cash....build it similar to a movable chicken coup. be sure to keep it really clean though, or predators will be setting up camp on your yard from the smell....if you live in a rural area as I do, in some parts, predators like foxes or bobcats will make your rabbits big targets. I suggest creating a covered coop.... a fox will likely still get in, but at least it will take some time.
4) Dressing -- I use a lever rabbit box that is very fast and very humane. It is a small lever that looks like a coat hook. It is painless and allows for fast skinning. Keep a few for breed stock, especially the big docile females. I tend to keep many of them as stock, then use the males for meat. The males will taste worse as they get older, whereas for females it won't matter.
Hope this helps. Good luck!
P.S. If you are intending to raise them and sell them to a processor for profit, throw out everything I just said. That is a whole other can of worms, and they want very specific things if you intend to sell. I can help there too if need be, but disregard the above. I am assuming they would be for personal use.
