“…Various studies revealed that enriched environment (environment with improved living conditions) significantly impacts on reproductive performance, weight gain and better survival proportion (Whitaker et al, 2009). It brings positive change on the quality of oocytes as well as reduces the chances of cannibalism (Fisch et al, 2017). Enriched environment provides improvement in reproductive performance, boost up immunity, reduce behavioral abnormalities and stress (Fisch et al, 2017;Laviola et al, 2004).…”

Rat is one of the most commonly used model animals for biological research. The organs and systems of human being are somewhat similar to that of rat in structure as well as functions, making it a valuable choice for research experimentation in biological sciences. A number of studies have been conducted to evaluate the potential risks and toxicity of different elements on the physiology and histology of rats. There is need to address certain environmental factors affecting rats condition during experimentation. Reproduction along with its pathologies is under investigation on larger scale throughout the world, being central for the existence of a species. These studies focus on the major factors that influence reproductive function. Review of literature clearly indicated the unwanted consequences of over nutrition, malnutrition, high or low temperature, non-enriched housing, improper handling, intense or poor light exposure and environmental pollution on histology and hormonal profile of reproductive system of rats.

“…Previous reports have shown better outcomes in the number of pups weaned per dam and pups weaning weight in three different mice strains when nesting materials were provided, compared to the control group [ 15 ]. Additionally, it has been found that EE promotes a greater number of viable oocytes induced by superovulation in rats [ 16 ]. On the other hand, other authors did not find any effect of EE on reproductive parameters [ 17 , 18 ].…”

The aim of this study was to evaluate the effect of an environmental enrichment (EE) plan on the reproductive performance of Swiss Webster mice and their female offspring used as recipients for embryo transfer. A total of 54 breeder mice and 60 F1 females, used as foster mothers, were allocated in two experimental groups to receive or not receive EE for physical well-being. Reproductive outcomes of the Swiss trios such as birth rate and pup number, litter size, pups’ weight at weaning, interlitter interval and time to first litter were analyzed. Environmental enrichment significantly increased pups weight from breeding trios compared to the control group (14.4 ± 0.1 vs. 13.8g ± 0.1, EE vs. control, respectively; p < 0.01). Other parameters did not differ between both groups. Reproductive parameters of female offspring used as recipients for embryo transfer did not differ among groups subjected or not to EE. These data demonstrate that the EE protocol applied in Swiss Webster breeder mice positively enhanced pups weight, and did not interfere with other reproductive outcomes. In conclusion, this study supports the implementation of EE plans usually applied for animal welfare in mouse facilities with slight improvement in reproductive performance.
