Effects of copper and selenium on antibody response, weight gains and blood parameters in beef calves grazing high or low endophyte (Acremonium coenophialum) tall fescue (Festuca arundinaceae, Schrep)

Parenteral Se and/or Cu was used to supplement growing beef calves (age 7 months) marginally deficient in these two trace elements and pastured on high-endophyte (HE) or low-endophyte (LE) tall fescue. The 64 calves were randomly assigned to one of eight treatment groups (HE or LE, supplemented or non-supplemented Cu, supplemented or non-supplemented Se) and pastured for an 84-day study period during summer months, 4 animals on each of 16 paddocks (8 HE = over 85% infestation, 8 LE = under 20% infestation) 2.024 hectares in area. Parameters included weight gain, whole blood Se concentration, serum Cu concentration, trichloroacetic acid-precipitated serum Cu concentration (TCA-Cu), serum clinical chemistries, hematological evaluations, and serum antibody response (IgG and IgM) to a synthetic antigen, TGAL, as measured by ELISA.
