Description
Depressed concentrations of serum prolactin (PRL) have been observed in cattle grazing tall fescue (F. arundinacea Schreb.) infected with the endophytic fungus A. coenophialum Morgan-Jones and Garns (Thompson et al, 1987). Lower PRL concentrations may be partially responsible for poor performance of cattle consuming endophyte infected (E+ ) vs .. noninfected (E-) fescue since PRL is involved in mammary gland development, thermoregulation, and immune response. To determine the relationship between PRL concentration in cattle and percent E + plants in pastures they graze, studies were conducted at two locations in Tennessee.
