ROMERO VIDOMLANSKY, P.R. et al. Preliminary study of some growth and fertility variables of bioterium mice. Rev. vet. [online]. 2023, vol.34, n.1, pp.62-66. ISSN 1669-6840.


In the present work, the results obtained in the comparative study of the growth and fertility of Balb/C and CF-1 mice from the Bioterium of the Faculty of Medicine of the National University of the Northeast are exposed, by modifying the environmental conditions of breeding and reproduction of the animals before and after the moving of the Center to its new facilities. The characteristics studied in both strains were: breeding number, weight according to sex before and after weaning, until to the 15th week of life, and fertility rate. The results obtained show that the moving caused stress in both murine strains, and the effect was manifested in the decrease of growth and fertility rates observed in the animals. These values were not statistically significant, which allows us to conclude that the enrichment of the habitat in the new facilities helped to alleviate in some way the stress of the move. This is the first systematic study carried out for this purpose and lays the foundations for others for monitoring the adaptation and production in the new facilities.
