Japanese quail from the S16 generation of lines selected for high (HR) and low (LR) plasma cholesterol response to adrenocorticotropin (ACTH), and the randombred control line (C) from which the selected lines had been derived, were immunized with a heat-killed Salmonella pullorum antigen. Plasma from blood samples taken at 0,5,8, and 12 days postimmunization was titered for total agglutinin levels. A quadratic equation and its first derivative, calculated for each bird, produced mean values by line for maximum titers, mean day of maximum titer, and rate of titer decline. Results indicated that the LR line had significantly lower titers than the HR or C lines but that the HR line reached maximum titer later than the LR line. The rate of titer decline was fastest in the C line.
选用对促肾上腺皮质激素（ACTH）产生高（HR）和低（LR）血浆胆固醇反应品系的第16代日本鹌鹑，以及作为所选品系来源的随机繁殖对照品系（C），用热灭活的鸡白痢沙门氏菌抗原进行免疫。对免疫后0、5、8和12天采集的血样血浆进行总凝集素水平滴定。为每只鸟计算的二次方程及其一阶导数，得出各品系的最大滴度、最大滴度的平均天数和滴度下降率的平均值。结果表明，LR品系的滴度显著低于HR或C品系，但HR品系达到最大滴度的时间比LR品系晚。C品系的滴度下降速度最快。
