The effect of intracerebroventricular injection of corticotropin-releasing factor (CRF) on various behaviors in chicks was determined at 15-min intervals over a 30-min period. Food intake of chicks was significantly decreased, and pecking rhythm was significantly delayed by CRF during the first 15-min post-injection. The similar tendencies were observed in the second 15-min post-injection, but not significantly different. Stepping, as an indicator of locomotion, was not different at 15-min post-injection, but was increased by CRF, thereafter. These results suggest that CRF acts within the central nervous system to decrease food intake and increase locomotion in the chick.
在30分钟内每隔15分钟测定一次脑室内注射促肾上腺皮质激素释放因子（CRF）对雏鸡各种行为的影响。注射后前15分钟，CRF显著降低了雏鸡的食物摄入量，并显著延迟了啄食节奏。在注射后的第二个15分钟观察到类似趋势，但差异不显著。作为运动指标的踏步在注射后15分钟时没有差异，但此后CRF使其增加。这些结果表明，CRF在中枢神经系统内发挥作用，减少雏鸡的食物摄入量并增加其运动量。
