[QUOTE="alexfarms, post: 593093, member: 8677"] The pics of these dead calves look very familiar from 2 unrelated Hereford lines I worked with prior to getting my King Dominos. I sent them to Dr Steffen and he said at that time that if they were genetic abnormalities then they were a genetic abnormality that had not yet been identified. They were UGLY, cleft pallet, twisted, small. They were full term to 10 days late in gestation. The cows didn't freshen normally. I had to pull one of them, it was like the cow didn't dialate. I believe I had 5 of them over a 10 to 12 year period. The only thing Steffen could conclude at the time was "placental insufficiency". Which can be caused by lots of things, but this acted like a simple recessive genetic abnormality. 3 of the calves were from half sib matings. The other two were linebred within their lines. They were produced by 3 bulls in the one line. I sold all 3 of them because the calves were just too weird. Then I got 1 son of one of those 3 bulls that I could breed to anything and got no problems. That even made me more suspcious of a simple recessive that that bull didn't inherit. I concentrated on that bull until I had the chance to buy the King Dominos. The other line I got one dead calf out of was years ago using an AI bull. That calf was overdue also. Very ugly little calves. One story I was told at the time was that exposure to a virus at conception could cause some type of problem with development and cause those ugly dead little calves. There will be alot of questions asked from this CCS identification. Most likely the AHA will say nothing until after the genetic marker is discovered, then we'll probably be able to test our cattle and put a "FCCS" behind their names....or not. [/QUOTE]
