Lets take a look at its nutritional data and find out a bit more.

A good amount of vitamin a and c would also be a good bonus.

As you can see marrow contains a little phosphorus, is quite acidic, a hint of fat and some sugar.
It also contains a very good amount of vitamin c which is fantastic for guinea pigs.
So with all that in mind, guinea pigs can eat marrow, but only once or twice a week at the most in small chunks. Because of its vitamin c content, it makes a good addition to their diet.
They can also eat the rind or the skin as it is very edible. However, be sure to strip away the seeds so they don’t choke on them.
