You can feed the same protein for the whole bag. A lot of people make huge batches of the same mix that last for months. Some people never change their recipe. Personally, I like to make small batches, and rotate every time...about every 8-10 days.
If you figure that a lot of cat owners feed their cats Purina Cat Chow for the cat's whole life, you're doing much better than that even if you feed the same raw mix over and over. As long as it's balanced and your cats don't get bored, you're ok. Rotation is better and I think healthier, but it isn't mandatory.
