Abstract
• Inflammation caused by bovine respiratory disease (BRD) continues to be one of the greatest challenges facing beef cattle producers and feedlot managers.
• BRD results in decreased intake, daily gain, and feed efficiency in feedlot calves, decreasing growth rate and increasing required days on feed.
• Morbidity caused by BRD has been associated with decreased hot carcass weight and poor carcass characteristics.
• Acute phase protein production in the liver, initiated by proinflammatory cytokines, may shift the priority for amino acid and energy use by the host animal during periods of sickness.
• Nutrient requirements for stressed calves seem to be the same as for nonstressed calves; however, nutrients should be concentrated early in the receiving period to account for low dry matter intake.
