Can someone please help me find a way to interpret the inbreeding/linebreeding statisitcs you find on horses pedigrees? For instance what does the letter (S) mean after a number? How about the (D)? Why when you pull a pedigree on say Equiline do they highlight some inbreeding stats and not others? Are the Chef Des Reines? I am trying to decipher this in order to evaluate TB mares for sport horse breeding.
As far as I understand it, the (S) and (D) are for sire and dam.
Ie: War Relic 4S X 4D means that War Relic appears in the 4th generation on both the sire's side and the dam's side. I would assume that Equineline only shows the inbreeding/linebreeding that appears on the first page (5 generations). But, someone with more knowledge might correct me
