Almost all types of meat and bones are acceptable in a raw diet. Things to consider are: chicken /turkey necks , backs, wings and carcases are close to the 'right' ratio of meat to bone. Another reason that they are preferable is because they are most often butchered very young. Animals that are butched later in life contain more toxins in the bones.
Here is some information on specific meats:
Beef: Beef contains a higher level of of protein than chicken, lamb or pork. It usually has less fat and therefore less energy than other meats, which does mean that it contributes less to obesity. Beef is very low in calcium. IT has good levels of iron and zinc. It contains small amounts of the B vitamins (1, 2 & 3) but very little of any of the others. Dogs fed mostly beef, seem to have more health problems than when lamb or chicken is fed. THis may be due to a lack of essential fatty acids.
Sheep or lamb: lamb is very fatty. Fat can make up to 30-40% of what you feed. It usually supplies more essential fatty acids than beef. Zinc varies in sheep meat from 2%-10%. If your dog has a zinc deficiency, the shank and neck chops are your best choice. Dogs with skin problems from a dry food often do better on lamb than beef. Calcium levels are a bit higher in lamb than in beef. Sheep meat particularily if it is on the bone is a valuable food.. This includes shanks, breasts, chops, legs, shoulders, ribs necks, pelvis, backbone etc.
Chicken: the best all around meat for dogs. (fed on bone or ground with bones) It can be the fattiest meat fed to dogs. THey are an important source of essential fatty acids. It has higher cholesterol levels than beef. Protein is lower than in beef, lamb or pork. Compared to other meats chicken is much higher in vit A, but still does not have enough to satisfy all your dogs requirements. IT has adequate levels of B vitamins.
Pork: Pork is an excellent meat for dogs having a good balance of essential fatty acids, good quality protein which is high in essential fatty acids. Pork contains virutally no vit A.
Things to remember. All meat you feed should go through an inspection process!!! As your dog ages, the white meats are far more healthy for dogs than red meats. Red meats are more associated with more degenerative conditions such as arthritis. You should also be feeding offal from a variety of sources.
Dogs should eat a variety of meats, not just one source!!!
Bones
Beef: beef bones may be the 'older' bones and they will probably be harder, there may be more toxins and because they are harder may break dogs teeth. Bottom line, try to fed bones from younger animals.
Lamb: they can be very fatty , which can be good, although to be avoided in instances where it is 'hard' on the dog. (or cut the fat off) Lamb bones come from a young animal. THe bones are soft with few toxins. Hydatids are not a problem if you purchase the bones from a butcher.
Chicken: in terms of nutritional quality , safety, thier contribution to dental and therefore general health, easy availablity and their cheapness these would have to be the 'best' choice. Chicken meat also does not contain hyatids (type of tape worm)
I could find nothing on trichinosis in any of my raw books (and I have lots of them), so I would ocnclude that it is not a concern!

Anyone feeding a raw diet should purchase this book or others on the topic.
