Basically meat is meat.. if it comes from an animal, a ferret can eat it. Venison is a great red meat, especially if it's free.
I'm going to copy/paste some information here that may be helpful, along with a basic sample menu.
"When feeding frankenprey, there are
4 main PARTS of an animal that we need to feed to meet the diet requirements: muscle meat, heart, organs,and edible bones. Remember that at least 3 proteins are required for complete nutrition. Those 3 proteins should be in the meaty part of the diet, not in the organs. However, you should also have a good variety of sources for organs, not all chicken organs, or all beef organs.
1)
Muscle meat is fairly self-explanatory. It is any kind of meat that is NOT an organ, including hearts and gizzards. When discussing muscle meat, however, we are typically referring to skeletal muscle.
2) While
heart IS a muscle meat, it is a cardiac muscle rather than a skeletal muscle, and it is in a category by itself because it is a vital source of taurine in a raw diet.
3) Nutritional
organs are considered to be any part of the body that SECRETES a hormone. Examples are liver, kidney, thymus, pancreas, reproductive organs, lungs, brains. Liver is the easiest organ to find and should make up at least half of the organ requirement. Other organs can be very difficult to find except directly from a butcher, cultural markets, or online sources.
Neither hearts nor gizzards are organs. This is a very common misconception, so be aware of it when shopping for organs. Many meat department personnel and butchers commonly call hearts and gizzards organs, but they are NOT. They are muscle meats, AND heart is a separate requirement in a ferret’s diet (see above).
4)
Edible bone is any bone small enough for a ferret to eat. Generally, these are non-weight bearing bones of poultry or small animals. Because we do not feed a bare bone, but rather one with plenty of meat attached, we sort of combine this category with muscle meat and call it “edible bone-in meat”. When I (or others) refer to “bone-in”, this is what we are talking about. If we refer to “muscle meat”, we mean meat that has no bone included (chicken breast, beef roast, etc.) Examples of edible bone-in meats are poultry wings, necks, backs, ribs, sometimes thighs, whole quail, whole Cornish game hen, rabbit, mouse, guinea pig. Sometimes you can find smallish bones from a larger animal that are small enough for a ferret to eat. One example is pork button bones, or pork riblets. Some of those bones are too dense, but occasionally you can find some small enough. Although the bone requirement is only 10-15% of the total diet (remember that we use the poops to determine the bone content), because the bone is attached to muscle meat, edible bone-in meat makes up the majority of a ferret’s diet. It is critical that your fuzzy learn to eat and enjoy bones, for healthy teeth as well as to meet the calcium requirements.
Now, moving on to the basic frankenprey menu:
Raw fed ferrets are generally fed twice a day, 12 hours apart, making a total of 14 meals per week. The basic weekly menu should include:
1 ½ meals of heart (~10% of the total diet)
1 ½ meals of organ, at least half of which must be liver (~5% liver, 5% other organ)
7-9 meals of edible bone-in meat (~50-60%)
2-4 meals of muscle meat with no bone (~15-30%)
When building your menu, you want to consider the effect a particular meal will have on the poops. For example, remember that blood rich meals (liver, other organs, hearts) cause looser poops, so to combat that issue, you want to feed at least one bone-in meal between them. It is best to spread organ/heart meals out as much as possible throughout the week.
This is easier than it sounds. Below is a sample menu. You can use this as a 'fill in the blank' menu.
Sun AM: organ meal (½ liver, ½ other organ)
Sun PM: edible bone-in meat
Mon AM: edible bone-in meat (or muscle, depending on poops)
Mon PM: edible bone-in meat
Tues AM: heart
Tues PM: edible bone-in meat
Wed AM: muscle meat
Wed PM: edible bone-in meat
Thur AM: heart and organ (½ liver, ½ other organ)
Thur PM: edible bone-in meat
Fri AM: edible bone-in meat (or muscle, depending on poops)
Fri PM: edible bone-in meat
Sat AM: muscle meat
Sat PM: edible bone-in meat
