摘要: Fecal progesterone assays were conducted in 3 captive female sun bears (Helarctos malayanus) segregated from males to characterize the species-specific reproductive pattern their original distribution area Sarawak, Malaysia. Peaks of fecal concentrations observed once annually, and lactation was after increasing all females without mating stimulus. These results suggest that Malaysia, may have a seasonal ovulation noted occur spontaneously, followed by pseudopregnancy.
