The progesterone concentration of peripheral plasma in pigs has previously been studied during the oestrous cycle and in early pregnancy ( 1967, 1969). The present study was undertaken to obtain some information on the concentration of plasma progesterone during the prepuberal period and during the first oestrous cycle in the pig.
此前已对猪发情周期和妊娠早期外周血浆中的孕酮浓度进行了研究(1967年、1969年)。本研究旨在获取有关猪青春期前阶段和第一个发情周期血浆孕酮浓度的一些信息。
