Bone & Fat Content Percentages in Raw Meaty Bones

Since different bone in cuts can have varying amounts of fat and bone content, sometimes it can be difficult to figure out how to calculate the bone content percentage in a “prey model” raw diet.

Figuring out how much fat is present in the diet can also be helpful, especially for animals that require a certain amount of fat in their diets. Knowing the percentages of these products can make that job a lot easier.

Here’s Petfoods4u's guide to bone and fat content in raw meaty bones.

Remember: in a “prey model” raw diet, you want to aim for 10% bone.

This 10% value is for only bone, not the entire RMB. “BARF” diet percentages call for anywhere from 25-60% raw meaty bones in the diet – these higher and more varied percentages are due to the fact that there is such a large variation in bone content depending on what kind of RMBs you’re feeding.

If you fed chicken necks and backs as 60% of the diet, for example, that would be way too much bone! RFC prefers the “prey model” percentage of 10% bone content for this reason.

Figuring out what and how much to feed to get the right bone content in the diet might sound complicated, but it is actually just a bit of really simple math. Let’s say you have an 80 pound dog that eats 2 pounds of meat a day (which would be 2.5% of the dog’s weight, right in the middle of the 2-3% guideline).

You want to incorporate duck wings as a source of bone in his diet, which are 50% bone. You think, what if I fed duck wings as half the meal? 50 divided by 2 is 25%, so that is still too much bone. What about a fourth of the meal? 50 divided by 4 is 12.5%, which is much better! So for a 2 lb total meal size, 0.5 lb of that should be duck wings. The rest can be meat, organ, and whatever else you’re adding – egg, veggies, etc.

You don’t have to feed exactly 10% bone in every meal – you would spend all your time doing math and trying to cut meat into impossible sizes to get that to work every day! The 10% value is something you should aim for over time – it doesn’t have to be exact. So don’t obsess over 10%, just use it as a guideline.

Remember to choose bones that are appropriate for your pet! If you have a large dog, chicken necks might be too easily swallowed whole, which is a choking hazard, but for small dogs, cats, and ferrets, chicken necks are great RMBs. A good RMB for a Great Dane might be a slab of pork ribs, but a Chihuahua that tries to eat pork ribs might end up with a cracked tooth. Choose RMBs accordingly!
