N-乙酰转移酶活性（NAT）在鸡的松果体和视网膜中表现出昼夜节律，并负责褪黑激素的昼夜节律。鸡松果体NAT测定在体内和/或体外光-暗周期后，短光周期，长光周期和恒定光预处理后。先前的照明改变了体内节律的形状（相位、振幅和持续时间）。一些改变是“编程”到松果体，因为他们在体外观察到松果体从小鸡同样暴露于照明预处理。
N-Acetyltransferase activity (NAT) exhibits a circadian rhythm in the pineal gland and retinas of chickens and is responsible for melatonin circadian rhythms. Chick pineal gland NAT was measured in vivo and/or in vitro after light-dark cycles and after pretreatments with short photoperiod, long photoperiod, and constant light. Prior lighting changed the shape (phase, amplitude, and duration) of the rhythm in vivo. Some of the alterations are "programmed" into the pineal gland because they were observed in vitro in pineal glands from chicks similarly exposed to lighting pretreatments.
