I can see you've been talking to my mom Wink
I don't think its a coincidence that some of the breeds with the highest marbling are dairy breeds
man, word spreads fast, i hope you get to be as smart as she is. post pics of that steer we talked about when you get them.
this is just my opinion and observations of looking at perhaps 300 beef carcasses per year, in lots of 5 from a variety of breeds for 3 years against dairy, that selection moved the fat in dairy as it was visually removed from the back. it went both in the muscle and inside the rib cage in spite of selection to remove it to push production to milk instead of fat. with feed not a limiting factor (compared to beef) the cow's system knew what it needed in fat to maintain production and fertility.
i can't say there is a corrolation to bone plate mass and or shape (flatter as oppossed to round) to marbling based on info so far and my bias of info in slaughterhouse and the supposed high heritability of marbling, roughly .40. at this point all i can conclude is that it is corrolated, but not yet casual in my mind. with the amount of dairy slaughtered, someone could do a senior project on that very easily.
