2003 Florida Equine Institute Minor differences may be more difficult to detect until scoring has been practiced. Condition scoring requires a modest amount of training and will improve with experience. First, know the definition of Body Condition Score 5. A BCS 5 horse will look average neither fat nor thin. The ribs cannot be seen, but can be easily palpated. The horse's back will be level and the body will appear smooth. In addition, definition of muscling on the hind legs will be apparent. Figure 2. After a mental picture of a BCS 5 has been established, this image can be used as a benchmark for determining other condition scores. Condition scores of 4 or higher generally reflect fat deposition, whereas BCS 3 or lower often reflects both fat and muscle loss. Second, visually and manually evaluate the amount of fat deposition and muscling as it occurs on the following sites: / behind the shoulder / ribs at mid-barrel / crest of neck / withers / crease of the back, and / at the tailhead. Third, consider external and internal factors. Fill or shrink from digestive contents and/or pregnancy can change the appearance of moderately fleshed horses. Long hair may also make it difficult to visually appraise body condition. When horse are difficult to evaluate visually, the amount of body fat in relation to musculature must be determined by feel. Finally, compare result of direct observation and manual palpation with the descriptions of body condition scores given in Table 1. Table 1. Description of Body Condition Scores BCS Description 2 Emaciated No evidence of any fat deposits. Bony structure of ribs, spinal column and hips prominent. Animal may show signs of weakness and/or uncoordination when asked to move. 3 Very Thin Very little evidence of fat deposits. Spinal column is the highest part of the horses back from the withers to the tailhead. 4 Thin Ribs are evident. Spinal column is the highest part of the horses back from the withers to the croup. A slight amount of fat may be felt around the tailhead. 5 Desired Condition The horse's body is smooth. Ribs are not visually evident, but are easily felt. Back is level, no crease or ridge noticeable. Withers are rounded, shoulders and neck blend cleanly into the body. Fat around the tailhead will feel spongy. Muscles of the hind leg are evident.
