A Dairy Cow Body Condition Scoring System and Its Relationship to Selected Production Characteristics

The objective of this paper is to characterize the fat cow syndrome. This condition refers to a combination of metabolic, digestive, infectious, and reproductive conditions which affects the obese periparturient cow. The condition develops primarily due to faulty feed management which permits excessive consumption of unbalanced diets. The syndrome is frequently a herd problem characterized by a high morbidity and mortality due to an increase in disease in periparturient cows. Clinical signs include depression, anorexia, ketonuria, marked decrease in production, progressive debilitation, weakness, nervous signs, and an elevation in temperature due to infectious disease. The obesity is generalized throughout the body with extensive fatty metamorphosis in the liver. Histological changes are primarily in the liver and kidney. Treatment of the condition consists of feeding a balanced diet, symptomatic treatment, and good supportive care. The condition can be prevented by feeding a balanced diet according to nutrient requirements of the National Research Council.
