Steps to Judging Sheep
1. Evaluate animals from the ground up and from the rump (rear) forward
2. Rank the traits for their importance
3. Evaluate the most important traits first
4. Eliminate any easy placings in the class
5. Place the class based on the volume of the important traits
Slide 1

Ranking of Traits for Market Lambs
1. Degree of muscling2. Degree of finish3. Balance and style4. Frame size5. Soundness and structural
correctness

Evaluating Degree of Muscling
To evaluate degree of muscling, pay close attention to:
1. Thickness through the center of the leg
2. Width between the rear legs when the animal is on the move
3. Length of the hindsaddle 4. Width and length of the loin 5. Grooved shape over the rack
Slide 4
![Page 6: Developed by: Richard Coffey, Extension Swine Specialist, University of Kentucky](https://reader035.vdocuments.site/reader035/viewer/2022062422/56813373550346895d9a8897/html5/thumbnails/6.jpg)
Evaluating Degree of Muscling
- Center Leg and Base Width -Light muscled(narrow)
Average muscled(average width)
Heavy muscled(wide)

Evaluating Degree of Muscling
- Width and Length of Loin -A wide loin is desired in market lambs
A long loin is desired in market lambs

Evaluating Degree of Muscling
- Length of Hindsaddle -
Hindsaddle Foresaddle
Greater length of hindsaddle (relative to the foresaddle) is desired in sheep

Evaluating Degree of Finish1. Lambs should be lean with an ideal
backfat thickness of 0.15 to 0.20 inches
2. Degree of muscling, frame size, and stage of maturity influence degree of finish
Watch out for short, light muscled lambs
Fat sheep will be widest over the top
3. Lambs that are lean will be: Very trim over and behind the
shoulder Extremely clean and neat
through underline

Evaluating Balance and StyleBalance deals with having equal
portions of width, depth, and length, with special emphasis on length:
Slide 13
•Sheep should be wide and deep at the rear and tight and trim through the front-end (Christmas tree shape)• Volume of weight in leg and loin
Style deals with correctness of structure and straightness of design:•A straight top line is desired
•A neat, smooth shoulder that blends smoothly into the neck and ribs is desired
