Fifty common marmoset pregnancies were monitored using ultrasound. The objective was to ascertain if fetal mortality was related to litter size. Prior to analysis we determined abortion rate and litter size were not influenced by repeated ultrasound. Mortality was unrelated to litter size and occurred fairly late in gestation. All singletons born in this study began gestation as twins. It is hypothesized that marmosets may be able to adjust litter size late in pregnancy in response to proximate environmental factors.
使用超声波监测了50只普通狨猴的怀孕情况。目的是确定胎儿死亡率是否与产仔数有关。在分析之前,我们确定流产率和产仔数不受重复超声检查的影响。死亡率与产仔数无关,且发生在妊娠后期。本研究中出生的所有单胎最初都是双胞胎。据推测,狨猴可能能够在怀孕后期根据近期环境因素调整产仔数。
