I haven't been on this board for sometime but when there's something I need to understand - this is the place you can usually get an answer! Thanks in advance for any inputs.
I have always bred using the rule of thumb of 3 generations back on both sides of the pedigree for the same sire/dam, however, I mistakenly bred a cow who's sire is Mytty in Focus to 44 Main St 7049 who has Mytty 3 generations back (ie great grandfather). So the resultant calf would have the same grandfather (on the dam side) & great great grandfather (on the sire side). I know there are means to determine the risk level involved with such breeding's but I'm not sure how to figure it out. Should I abort the calf if the ma is settled or let her have the calf or can anyone tell me how to determine the risk %?
I once had a calf (when using a bull) that had the same grandfather on both sides (father of dam & sire) & I had to but it down, as it was missing the A-hole - but that's pretty much a known high risk situation, I surely don't want that to happen again!
