Market Lamb EvaluationLindsay WarzeckaAGED 410 http://pw0nd.com/tag/wolf/
Who’s to Judge? • Livestock Judging Overview: • Knowledge of species • Demonstrate accuracy in evaluation • Support claims made with specifics • Make future carcass/production predictions
Learning Outcomes Standards addressed: • C6.0 Students understand animal anatomy and systems: • C6.1 Know the names and locations of the external anatomy of animals. • C7.0 Students understand basic animal genetics: • C7.2 Compare genetic characteristics among cattle, sheep, swine, and horse breeds.
Ranking of Traits • Degree of muscling • Degree of finish • Balance and style • Carcass merit • Soundness and structural correctness Why do you think the ranking of traits is ordered this way?
Muscling • Heavy muscled lambs highest rating • Natural thickness over the top • Thickness through the leg • Base Width Where do you think we could look for muscle indicators? http://cecalaveras.ucdavis.edu/Selecting%20Market%20Lambs.pdf

Lamb Evaluation: Muscle Indicators • Round • Expressive • Defined Rack Loin Leg www.michiganffa.com/association/.../intro_to_live_evaluation.ppt
Finish • Fat enough (but not too fat) • Prominence of bones is a sign of poor finish • Too much finish has a supple touch • Where on the lamb do you think we could look for indicators of fat?

Balance and Style • Overall attractiveness and symmetry the animal displays from profile • Uniformity • Gets “progressively deeper from fore-rib to flank” • Straightness of lines • Level topped, level rump
Carcass Merit • Weight of 90-110 pounds • High-priced cuts considered first: loin and rack • Good length of body (longest part last rib to hind-saddle) • Video example – Putting it together!
Soundness and Structural Correctness • Square set from hock to ground from behind • Heaviness of structure http://www.danekeclublambs.com/JudgingSheep.html
Proper angle to shoulder and knee • Appropriate set to pastern • Levelness of top and dock set http://www.danekeclublambs.com/JudgingSheep.html
It’s Show Time!! • Place animals in an order • Identify rankings/traits • Be able to explain/support
Placings • Placings: 4-1-3-2 • Cuts: 3-5-2 • Pretend like your judging the county fair! Work in groups to come up with a set of reasons you would give over the microphone.
Example Set of Reasons • I placed the market lambs 4-1-3-2. In the top pair of more muscular wethers, I personally like the blue sheep to win. For me, he ties his muscularility into a bigger, more correctly finished package. Not only is 4 a taller fronted lamb, that is longer measuring from his last rib back. But this compliments the fact that he is a cleaner profiling lamb that is likely leaner to touch. I would expect him to have an advantage in cutability. True, 1 is a heavier weight lamb that wraps with a bigger leg. However, I placed him second because he is a heavy middled lamb that is deep in his sternum. • However, 1 is a more powerfully muscled, growthier lamb, and needs to beat 3 in the middle pair. No doubt, 1 is a wider based sheep that has more tone and shape of muscle from his rack back into his leg. To add to this, I find him to be a heavier weight lamb and he should go to the cooler with more product from his 13th rib back. Yes, 3 is more correct in his body depth. However, for me he goes third, because 3 is clearly the lightest muscled, thickest hided lamb in the class, that is a bit too stale. • Now, in the bottom pair of lambs that differ in composition I elected to use the leaner lamb and placed 3 over 2. I predict he will have an advantage in yield grade because he should handle leaner down his spine and is especially cleaner appearing over his forerib. On the other hand 2 is a more muscular sheep. He has a bolder shape of muscle over his rack, a fuller loin edge and more volume to his leg. Nonetheless, I placed him fourth. Not only is he short bodied, but he is clearly appears to be the softest handling, most overdone lamb in the class. http://www.judging101.com/exampleclass.asp
