Decreased mononuclear cell response to mitogens in artificially reared neonatal pigs
The influence of two rearing methods for neonatal pigs on mononuclear cell responses to mitogens was studied. Littermate pigs were reared artificially or on the sow. Artificially reared pigs displayed a leukocytosis (P less than 0.05) characterized by an increase (P less than 0.05) in mature and imm...

Zusammenfassung: | The influence of two rearing methods for neonatal pigs on mononuclear cell responses to mitogens was studied. Littermate pigs were reared artificially or on the sow. Artificially reared pigs displayed a leukocytosis (P less than 0.05) characterized by an increase (P less than 0.05) in mature and immature neutrophils. Skin-test responses to intradermal injections of phytohemagglutinin were less (P less than 0.05) in artificially reared pigs than in sow-reared controls. Lymphocyte proliferative responses to mitogenic stimulation were approximately 50% lower (P less than 0.05) in artificially reared pigs than in sow-reared pigs. These data suggest that artificial rearing lowers in vivo and in vitro lymphocyte responses in neonatal pigs. |
