Using body condition scoring to fine Using body condition scoring to fine tune herd nutrition and health tune herd nutrition and health management has become a widely management has become a widely accepted practice. accepted practice.
This presentation is designed to This presentation is designed to Introduce you to body condition scoring Introduce you to body condition scoring Provide examples of cows scored 1 to 5 Provide examples of cows scored 1 to 5
Evaluating Body Condition vs. Evaluating Body Condition vs. TypeType
Type evaluation Type evaluation (classification, judging) (classification, judging) compares animals to the compares animals to the “ideal”“ideal” conformation conformation
Body condition scoring Body condition scoring considers the relative considers the relative fatnessfatness or or thinnessthinness of of animalsanimals
Goals of Body Condition Goals of Body Condition ScoringScoring

Visual and tactile evaluation of body Visual and tactile evaluation of body fat reservesfat reserves
Indication of energy balanceIndication of energy balance Scale of 1 to 5, increments of 0.25Scale of 1 to 5, increments of 0.25 Body Condition Score = BCSBody Condition Score = BCS
BCS 1 = emaciated cow (too thin) BCS 1 = emaciated cow (too thin) BCS 3 = average body conditionBCS 3 = average body condition BCS 5 = excessively fat cowBCS 5 = excessively fat cow

If an animal is grossly fat, the bone structure cannot be seen or felt through the fat. In thin animals, the bone structures are very prominent.
