Bovine Respiratory Disease Influences on Nutrition and Nutrient Metabolism.

Bovine respiratory disease (BRD) complex remains one of the greatest challenges facing beef cattle producers, veterinarians, and feedlot managers. In receiving, stocker/backgrounding, and feedlot cattle, BRD has been associated with decreased dry matter intake and daily gain, resulting in economic losses during the feeding period. Inflammation associated with BRD has the potential to decrease carcass yield and quality. Newly received calves are at various risks to contract BRD. Proper nutrition for newly received calves is key to recovery from stress associated with weaning and transport. This article reviews nutrient impacts on BRD and BRD impacts on nutrient metabolism.
