The ferret,Mustela putorius furo,as a new species in toxicology

Abstract

Summary

Comprehensive studies on the haematology, urine chemistry, serum chemistry and gross pathology have been carried out and reported. Seasonal weight changes were confirmed and were initiated, together with sexual activity, when ferrets were brought in to a constant temperature (18–19°C) and 14–hour daylight cycle during the winter months. Levels of haemoglobin, erythrocytes and haematocrit were higher than in most common laboratory species. Similarly, serum electrolytes and glucose levels were higher than in Wistar rats or beagle dogs. Ovaries, uteri and testes displayed a seasonal maturation and atrophy. All other parameters were similar to common laboratory species.
