Is it safe for a cow to get pregnant if it has a hernia?

Think about what a hernia is. What could happen if she did? Would this be safe? Why is this cow being breed? Are you going to eat her? Raise the calf to eat? For breeding stock? Why would you breed a cow that might pass on a tendency to have weak guts and pass that weakness on to the next generation? If you must have the vet fix it. Otherwise cull her out. No it is not safe. Find her a new home, down the road or in the freezer.
