Term-wise PGFM concentration measured by EIA in Asiatic lion, Bengal tiger and jaguar.

To examine differences in PGFM concentrations between different gestation periods, we divided pregnancy into three equal periods as early (1–5 weeks), mid (6–10 weeks) and late term (11–15 weeks) for Asiatic lion, Bengal tiger and jaguar.

为探究不同妊娠期的PGFM（Prostaglandin F Metabolite）浓度差异，本研究将亚洲狮、孟加拉虎及美洲豹的妊娠均分为三个均等阶段：早期（1~5周）、中期（6~10周）与晚期（11~15周）。
