In beef cattle, there are a number of common management practices that result in stress, such as weaning, castration, vaccination, transportation, and commingling.  Despite the source of stress, these activities lead to the activation of the inflammatory reaction, which is initiated by the production of pro-inflammatory cytokines (namely interleukin -1, interleukin-6, and tumor necrosis factor – alpha).  These proteins are the initial instigators of the acute phase reaction, which orchestrates the subsequent production of acute phase proteins and ultimately metabolism alterations impacting feed intake, nutrient utilization, and growth.  Major acute phase proteins in the bovine include haptoglobin and ceruloplasmin, both of which are commonly measured indicators of inflammation. Recent research has revealed links between trace mineral status and impacts on the acute phase protein response of beef calves. These effects appear to have short-term impacts on beef calf productivity, suggesting a direct correlation between trace mineral nutrition and the nutrient-costs related to optimal immune responsiveness.  This presentation focuses on the role of trace mineral nutrition on the acute phase protein reaction and subsequent impacts on performance among newly weaned beef calves.
