[QUOTE="Rmc, post: 1783366, member: 39072"] Every registered herd of all species is the result of line breeding. Each breed has a base inbred coefficient or I think the newer term some use is degree of relatedness regardless of wether you linebred or outcross within the breed. The modern marvel of AI has actually accelerated the effects of line breeding in increasing the entire registered breeds base degree of relatedness far faster than any form of traditional breeding could accomplish. Many say don’t linebred I don’t like it but don’t think twice about breeding a significant portion of their herd to the latest flavor of month bull that may end up being the sire to thousands of offspring in a single year. How many offspring can a bull produce in his lifetime as a result of demand sales? How many could he produce doing only natural cover. How many calves can a cow produce via embryo transplant compared to natural ways. If this isn’t line breeding what is it? Here is a interesting article on angus cattle [URL unfurl="true"]https://gsejournal.biomedcentral.com/articles/10.1186/s12711-021-00644-z[/URL] [/QUOTE]
