[QUOTE="kdpihf, post: 1611030, member: 6952"] Black Lode, Black Chang and Planter all have as their great grandsires sons of Prince Paul of Barnoldby. According to the AA website the inbreeding coefficient for Black Chang is 20.56%, Jotham Eric 17.38%, Planter 13.38% and Black Lode 13%. Don't forget those are average numbers and the real numbers can vary widely, and can certainly be affected by selection based on phenotype. As noted before just had a heifer hit the ground last week out of paternal half sibs (both sired by Alexegi of Craigie). Another heifer on the ground a few weeks ago out of the same Alexegi sired bull and an Alezus sired cow, Alezus was the sire of Alexegi so also a close mating. And the cows are also linebred on the bottom side to the same or similar genetics. Good genetics should be linebred if you are producing breeding stock. If you are selling by the pound then outcross away. If you want to maximize your individual animal's performance heterosis is your friend, if you want to deliver predictability with maximum performance to your customers then linebreed. Candolier Forever 376 was a sire daughter mating 7501542, EXT had Emulation 31 up close 2x, plenty of other examples around. edit to add maybe one of the best examples other than the Craigie line is Tim Ohlde and his use of F0203 [/QUOTE]
