Slaughter Cattle Evaluation • How does one go about evaluating market animals ? • All animals are evaluated on three traits • Muscle • finish (quality) • Correctness
Slaughter Cattle Evaluation • How does one evaluate muscle, finish (quality), & correctness ? • Visual observation from three views • Front • Side • Rear
Slaughter Cattle Evaluation • So, you evaluate finish, muscle, & correctness at each of the three views • Front • Side • Rear
Slaughter Cattle EvaluationFront View - Finish • Fullness in the brisket • Excess fat through the neck
Slaughter Cattle EvaluationFront View - Muscle • Width in the chest floor • Substance of bone • Muscle in forearm
Slaughter Cattle EvaluationFront View - Correctness • Width in the chest floor • Standing straight and solid on front legs • Do the feet toe out or toe in?
Slaughter Cattle EvaluationSide View - Finish • Amount of fat covering the last two ribs • Excess fat through the flank
Slaughter Cattle EvaluationSide View - Muscle • Amount muscle in the forearm • Length of muscle in the rear end
Slaughter Cattle EvaluationSide View - Correctness • Straightness of the lines; back, hips, & underline • Do want legs to far under the steer • Or to be too “post” legged
Slaughter Cattle EvaluationRear View - Finish • Square ness (shelving at the top of the rear end) • Square ness (shelving at the Bottom of the rear end) • A smooth round shape is correct
Slaughter Cattle EvaluationRear View - Muscle • Width through the center portion of the rear (stifle) • Length of muscle-especially in the lower quarter • Width of top
Slaughter Cattle EvaluationRear View - Correctness • Does the animal stand on feet correctly? • Or does he severely toe in or toe out
Slaughter Cattle Evaluation • Lets Judge a class of 4 Steers. Place them in order of best to worst, for example 2-1-3-4 or 4-1-2-3
Slaughter Cattle Evaluation • It’s probably best to place them from all views, considering all traits, then put a final placing on the animals
