Fertility problem - Desperate to get heifer in calf
I purchased my first dexter heifer last year at 14 months of age and put her to the bull at 16 months old. She came bulling regularly but the bull was not at all interested despite serving other cows in the field and having his first crop of calves on the ground. I then tried AI and after 3 attempts she is still bulling every 3 weeks and is not in calf! The vet gave her an internal and can find nothing obviously wrong so I now would like any advice as to where I go from here. The heifer is just what I wanted in a Dexter, the right size and confirmation, well handled and an absolute sweety so I am loathe to put her in the freezer but to keep her as a pet on the farm is not an option! Any advice would be greatfully received.
