While I'll be DNA testing to know for sure, I was wondering how the group here would handicap the odds that Bull A or Bull B is the sire of our newest calf.
Also, the BW of the first timer is unknown. Most of the calves calved by close relatives of this first timer are in the range of mid 60s to low 80s. A half sister of this first timer born last year was in the low 70s.
Bull A (cleanup bull):
* Known to have sired three calves, as follows:
--- 50lb heifer out of a 1st timer ... unknown live cover date
--- 61lb heifer out of a 2nd timer ... unknown live cover date
--- 62lb bull out of a 3rd timer ... unknown live cover date
Bull B (AI bull):
* Known to have sired four calves, as follows:
--- 72lb heifer out of a 2nd timer ... arrived on time
--- 73lb heifer (embryo calf) out of a recip (who was a 2nd timer herself) ... arrived two days early
--- 78lb bull (embryo calf) out of a mature recip cow of unknown age ... arrived two days early
--- 72lb heifer out of a 3rd timer ... arrived on time
The calf in question was a 74lb bull out of a first timer ... and was either two weeks late or a week early. Thoughts?
