title: Anamnestic response of neonatal chickens to sheep red blood cells as influenced by the number of weeks between the first and second injections.
abstract: In two experiments primary and secondary hemagglutination titers of chickens were determined in response to intravenous injections of 1 mL of a 5% suspension of sheep red blood cells (SRBC). All birds received the primary injection at 4 wk of age. In the first experiment, equal numbers of male and female birds were randomly selected to receive the secondary injection at 2, 4, 6, and 8 wk following the initial injection. Based on the level of IgG antibody to SRBC, all postprimary injections affected an anamnestic response. Furthermore, the anamnestic response obtained following the 6 and 8-wk postprimary injection was significantly higher than those obtained with injections 2 or 4 wk after the primary injection. In the second experiment, secondary injections were administered either 3 or 6 wk after the primary injections. The anamnestic response of birds receiving the 6-wk postprimary injection was higher than those injected 3-wk after the primary injections.
