newborn with hernia

So had a calf born with a hernia. Was a first time heifer but would not call it a long or hard labour. The vet today said that it could be genetic and that the bull may sire more. We have had 2 other calves by him, no issues, have 2 more coming. Now I wanted to use this bull harder this year as I am really liking the calves so far. Any one heard of, or had this issue with a bull? She said it could be the cow side too but wanted to cover both sides to see if I may be asking for more issues if I have more calves by this bull.
