[QUOTE="Ebenezer, post: 1344328, member: 24565"] Hate to say this, but when you post something on a chat site do you think the ones who read and posts are PhDs who know you and your management? A random one calf is no test but your cow proved herself as a dink producer before you bred her to her nephew for about a 12.5% IBC or whatever IBC it is. It is a minimal amount of inbreeding especially from a recent breed cross. Just to give you an idea of background, I have a strain of a breed of chickens here for pleasure and learning that has been linebred since the 60s. The closed sheep flock started with half sibs or stronger IBCs, the lines in the flock are continued to be built on either sire/daughter or dam/son lines and can be used for linebreeding or line crossing. No sheep people here but we are at zero need to worm and can get average lamb carcasses at 50%+ HCW/LW and all with no hands on pasture lambing. The bull currently with the cows is about a 1st cousin/1st cousin mating or closer, 5 sons wait to be used in coming years on half sisters and such based on a 50+ year old cattle learning curve and herd, the bull with the heifers is a full brother/full sister mating. He is breeding some daughters. The cows are adapted to KY 31 fescue due to generations of selections. The 7 YO bull with the heifers can run and jump like a spring calf just like the 6 YO bull with the cows, the sheep are improving, the chickens are laying better than ever without faults and such as that. So, you can cull my comments as I have no understanding of your circumstances. [/QUOTE]
