|I was just wondering if someone could tell me what the average Rib Eye size is for a lamb.|
|Sheepherder007||Posted 08/09/12 09:26PM Changed 08/09/12 10:44PM|
|Called a loin eye and 3 to 6 inch range in 70 # carcass|

|Rib eyes are cuts that involve the rib primal and as the name indicates a rib bone. |

|I believe you will find the proper description here is that the rib is a primal cut of the beef carcass and boneless ribeye roasts are quite popular and called Prime Rib.
I sincerely hope you don't teach meats judging.

|I know this is going to get ugly before it's all said and done. I have always known the primal cut with ribs as the rack. For many years we have always talked about Loin eye area (LEA). I see ASI refers to Ribeye Area (REA), yet also has references to LEA. So, am I to assume when you split the lamb and look forward towards the rack, that would be a REA measurement and when you look towards the rear that would be the LEA.
|redroper||Posted 08/10/12 11:04AM Changed 00/00/00 12:00AM|
|OYE, TAMU, and OSF all show the results as REA on their carcass data from the respective shows.|

|It doesn't matter to me what you all call it, I have just been asked during showmanship multiple times now how big I think my lambs Rib Eye is, which I believe is between 2-4 inches.|

|Tell em 3.5avg and we will. See how big this one is later|

|NSIP uses loin eye depth. So does most of the rest of the world.|

|In our fair's carcass evaluations over several years (the majority of the lambs shown and sold were evaluated, not just the winners), there was a fairly wide range of LEAs from about 2.4 to 4.2 square inches. Interestingly, LEA didn't seem to correlate too much with the weight of the lamb. The smaller lambs were just as likely to have a large LEA as the larger lambs. Depended more on degree of muscling than the weight of the carcass.|

|There is a connection and the experts have not found what it is between real fast gain of weight and a medium rate of gain. Very fast large animals have been shown to have smaller loin eyes than moderate ones. Australia is doing research on this.|

|Was at the recent National Sheep Symposium, and interstingly enough, most consumers perfer a chop with a average 2.5 eye. Most of all they want consistant size. While the club lamb industry is far removed from commercil production, the industry as a whole "could" produce that type of chop on a regular basis. What the consumer does not want is the chops from the 250 plus pounders still hanging out in Colorado feedlots. And I don't see that improving as most of the lambs bought today, buy 1 packer at least, are headed to the feedlots in Colorado. So they are placing 135 to 150 lb market ready lambs back on feed. Makes no sense to me.
Also of note is that Wooluller is correct. Most of these extremely large framed . high growth rams, produce smaller muscle shape than more moderate framed, more moderate grwoth rate rams. One more reason commercial producers have made a mass exodus from the "frame" type of genetics.However, some of the very high EPD rams that sold at the sale in Spencer, were pretty sorry as far as stucture. Most of the "number " breeders should probably have an unbisased person come in and cull some very poor stuctured sheep. Some of these rams would not make a breeding season on a large range operations.They had off the chart numbers as far as production , but really stuggled to move around the ring, after being penned for a couple of days. Some were very sound and mover out well.But as these rams for the most part, stayed in farm flocks, soundness was not as importnat I guess.The "number breeders" in cattle went that way as well, until they could not sell them anymore.
I also always like to see what lambs cut a larger eye, and where they were placed live. Most of the top lambs will have smaller eye, and the judge would have extolled virtues of the "very heavy muscled " lamb at the top of his classes, particularly the champs. Most of the time, these lambs are middle of the pack as far as eye is, when the hide comes off. They tend to be much fatter that thier peers, but more stylish. I don't get to shook up about those 5 in eyes, esp if the lamb has a front end like a mack truck, a hide like a chinese charpie,bone like a gizzly, and feet and lgs that point to the 4 corners of the ring. We don't eat pretty, but it is a show.

|The few things I've read say that ASI would like to see 3.0 as average, but the US sheep industry is still falling short at 2.7. Now when I look at our own fair's carcass data, it is closer to 3.5, with only a couple measuring less that 3.0 and about 20% measuring greater than 4.0. So these club lambs are considerably larger than average. I would be interested to see some measurements on the frame sheep. I wouldn't be surprised if they were lower than the club lambs and certainly lower on a cwt basis.|

|Ems, we know they are lower. That has been proven, High growth rate, with empasis on height=no muscle. Thier are outliers of course, and some flocks have a lot of muscle, but on average not so much in frame sheep. I think the average feedlot lamb, may cut about 46 to 48 close trimmed retail. Your clubbies will be as high as 56 or so if very lean and shrunk some. I seen some cull ewes at sale last few days. Some "framey " suffolks that weighed 310 or so. They were fleshy. I can imagine how much 8.00 corn went into those to get them to that weight. More than they brought. Were also some quite fleshy targee type at 285. Same deal. Some very fleshy Correidales at 295. These were ewes.. Rams were frome bony 150 rage to fat 400 range.|
