Does anyone know if its OK to give pregnant mice dog food?

I know you can give them biscuits because there high in fat, As is dog food. Giving them more fat/protein will make it less likely for them to eat there babies.

[The reason for eating there babies are 1. there stressed or 2. They eat them to get back all the nutrients they lost being pregnant and giving birth]

So does anyone know if its okay to give preg. mice dog food? [Along with there rodent blocks]
