Influence of acute feed deprivation or excess feed intake on immunocompetence of broiler chicks.


Immunocompetence was determined in chicks subjected to 24 h feed deprivation or excess intake by measuring 1) hemagglutinin titers in response to sheep red blood cell (SRBC) injections given either before or after dietary treatments, 2) delayed hypersensitivity to human gamma globulin (HGG), or 3) in vitro, phytohaemagglutinin-induced mitogenesis of spleen… (More)
