[QUOTE="Ebenezer, post: 1506975, member: 24565"] "I think for the long term, what's best is a uniformly selected herd (per ranch, or nationwide), but with a broad genetic base.. We're just starting to get the uniformity, but that's by reducing the genetic diversity with these AI sires that sire 1000's of animals" The most stabilizing program for long term survival of a species or breed are segregated populations (herds), with gene concentrations in the herds that are not outcrossed. American Livestock Conservancy has some good reading along those lines. Let those populations cull recessive problems and reshuffle the genepool when outcrossed to other lines. The weakness is getting folks to adhere to the need to create and improve fairly closed lines. [/QUOTE]
