Haemoglobin synthesis has been studied in fetal sheep. The switch from gamma to beta chain synthesis occurs rapidly between 130 and 150 days. Fetal hypophysectomy delays the rate of switching but the timing of the onset of the switch is not under pituitary control.
已对胎羊的血红蛋白合成进行了研究。从γ链合成向β链合成的转变在130至150天之间迅速发生。胎儿垂体切除会延迟转变速度，但转变开始的时间不受垂体控制。
