Metabolic diseases are associated in that the occurrence of one increases the risk of another. These associations tend to leverage the impact of disease on the animal.

Body condition scores (BCS) provide an indication of the energy status of dairy cattle. Condition scores can be used on both heifers and cows, although primarily they are used on the lactating dairy herd.

This evaluation is accomplished by assigning a score to the amount of fat observed on several skeletal parts of the cow. Various point systems are used to score the animal. The most commonly used system ranges from 1.0 to 5.0, in increments of 0.1 or 0.25. One point of body condition equals 100 to 140 pounds gain in bodyweight. Larger frame cows require additional bodyweight to increase one point, compared to smaller frame or narrow cows.
