Environmental change and housing conditions result in disappearance and return of reproductive seasonality in rhesus macaqes (Macaca mulatta)

Rhesus macaques in their natural environments, as well as in the free-ranging colony at Cayo Santiago, Puerto Rico are highly seasonal breeders. Many animal species lose breeding seasonality when brought under captive conditions. The present study that covers a period...

Effects of breeding configuration on behavior, reproduction, and pathology in the laboratory mouse (Mus musculus)

While numerous published studies have evaluated the effect of housing density on the wellbeing of laboratory mice, little is known on the effect of breeding configuration. The eighth edition of the Guide for the Care and Use of Laboratory Animals...

What is the impact of low testosterone levels on the anatomical and behavioral repertoire of long-term enriched housing of male mice? Behavioral Processes 108, 57-64

Environmental enrichment is a strategy to improve animal welfare, providing brain plasticity with changes at cellular, molecular and behavioral levels. In order to test the long-term effects of enriched housing and the importance of testosterone levels for the expression of...

Aspen shaving versus chip bedding: Effects on breeding and behavior

The choice of laboratory cage bedding material is often based on both practical and husbandry issues, whereas behavioral outcomes rarely appear to be considered. It has been noted that a breeding success difference appears to be associated with the differential...

Effect of cage space on behavior and reproduction in CRl:CD(SD) and BN/Crl laboratory rats

The 2011 Guide for the Care and Use of Laboratory Animals contains recommendations regarding the amount of cage space for mothers with litters. Literature on cage-space use in breeding rats is sparse. We hypothesized that, if present, differences in behavior...

An incidence of pseudopregnancy associated with the social enrichment of rabbits (Oryctolagus cuniculi)

Here we describe a case of pseudopregnancy in a New Zealand White rabbit as a result of pair housing with an aggressive conspecific. Clinical signs included fur pulling and nest building that developed shortly after separation from the aggressor. An...
