Introduction to Sheep Selection

ObjectivesDiscuss criteria sheep selection.Identify structural correctness and

reproductive correctness.Evaluate the frame and growth, breed

differences, muscle, volume and growth.

Criteria for Sheep SelectionSoundness

StructuralReproductive

Frame and GrowthVolume and CapacityMuscleBreed Character

Structural CorrectnessCorrect joint angles

Shoulder, knee, hock and pasternStrong top Level rump structureLarge, square footAdequate bone

Structurally Correct Ram

Structurally Correct Ram

Structurally Correct Ram

Structural Incorrectness

Reproductive CorrectnessDeveloped vulva on femalesCorrect testicle development and shape on

males

Frame and GrowthLarger framed sheep will be later maturing

and stay leanerLarger framed sheep will be growthierLong fronted, long necked desirableCorrect frontends most critical in sheep

Smooth shoulderCorrect neck - shoulder junction

Large framedLong bodied

Small framedShort bodied

Breed Differences

Southdown Cheviot

Volume and CapacityCritical for feeding and breeding capacityFleshing ability critical in ewe flockDeep, bold sprung rib cageWide chested and wide based

Volume and Capacity

MuscleEvaluated through the rump and topCritical in all meat animal production

Breed CharacterMore highly emphasized than on hogs or

cattleSubjective evaluation on many breeds

Suffolk Breed CharacterBlack head and legs free from woolLong, pendulous bell-shaped earRoman nose
