I bought a registered polled hereford cow this spring and she had a heifer calf. I thought she was scurred at three months old because they wiggled but they kept growing and they are 21/2" horn know. So I went to herfnet to look to see if I could find were the horns came from in her pedigree BRL CALL 100L & NJW 1Y WRANGLER 19D both have horned progeny. So I started searching several popular AI sires and I could not find any that did not have horned progeny. Who are the homozygous polled hereford bulls? Should'nt there be homo polled bulls out there that have zero horned progeny?
reg # on heifer if anyone would care to look 42932330 I would post the link but dont know how to.
I am probably mistaken, so anyone that knows feel free to correct me....
I am under the impression the only way to know, with at least a 99% confidence level if a Hereford is homozygous polled, other than DNA testing, is to go back to the orginal branch of the mutant polled Hereford(s). Just a guess, but this is probably why this or these animals are not listed in the AHA database. If this information was there, I think I could figure it out programatically by using a simple formula.
If you mate a polled bull to a dozen or more horned cows - and you don't get any horned calves as a result -the probabilty is really high(virtually 100% accuracy) that the bull is homozygous polled.
And I've already told you why many of the animals with birthdates pre-1960 weren't in the AHA online database. Speculate all you want, but the reality isn't nearly as sinister as where your non-trusting mindset continually takes your thoughts.
