    Abstract / Zusammenfassung

    In this study the effect of two different housing conditions on physiological parameters as well as fetal growth and seasonally different reproductive investment in the wild guinea pig was examined. We found a significant effect of housing condition characterized by a body mass loss and higher basal cortisol levels in animals kept indoors compared to animals kept outdoors.
    Furthermore, the fetal growth was characterized by repeated ultrasound measurements during pregnancy. The data may help to estimate gestational age in the wild guinea pig and showed no significant differences to previously reported data of the domesticated guinea pig. In a third experiment the seasonally different reproductive investment was examined. The wild guinea pig reproduces year-round but the reproductive investment is strongly affected by seasonally changes.
