Structure and vascularization of the kidneys of the nutria (Myocastor coypus)

Nutria have been raised for fur or meat for many years, the limited number of papers on their kidney anatomical structure prompted us to conduct the present study. The experiment was designed to present and describe the anatomical structure of the kidneys of the nutria (Myocastor coypus). It included 6 dead specimens of this species from breeding. The organs in question were initially excised and subjected to more detailed analysis in terms of dimensions, location in the abdominal cavity, but also vascularization. Arteries and veins were injected with red and blue LBS 3060 latex, and we used an electronic caliper to measure individual dimensions. Comparison of the parameters of the two nutria kidneys showed some differences, relative to other rodent species, which are discussed in the discussion.
