If a miniature calf was born to full size heifer and bull, can the calf be eventually be bred? Possibly with a miniature bull? Or would it possibly throw a full size calf, which could be life threatening?

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

If this calf was born to full size parents, then we'd suspect this to have been a developmental fluke or at least a genetic recessive trait. Therefore, if she were to be bred to in the future, there is a significant risk that her calf would be too large for her to deliver. Since miniature stature isn't a genetic trait that has been isolated in the bovine genome, even breeding her to a miniature bull would carry a risk of an normal/oversized calf (if he happened to not be fully recessive at the same gene). Therefore, unless you were prepared to have her potentially have a C-section if she did have complications or possibly even an elective one near her due date; then it would not be advisable to breed this lass.

All the best,

Dr. B.
