I have a reg. Beefmaster calf due in the next week or so. The dam is a granddaughter of Levi. The sire is also a grandson of Levi. Different parents of course. I think this is called double line or line breeding? Are there any drawbacks or dangers with this? If we have a heifer, I plan on keeping her and breeding her to my Beefmaster bull who is out of Country Western lines. That is, if she has no health issues. Any thoughts would be great!
