(20) The following order of animal sera was defined in comparison to human sera: cattle, pigeon, duck, sheep, cat, turkey, swine, coypu, hen, dog.
Nutria
Definition:
(n.) The fur of the coypu. See Coypu.
Example Sentences:

(3) The chromatographical components of nutria hemoglobin proved to differ in their physical and chemical properties as well as in the structure.
(4) Because ursodeoxycholic and chenodeoxycholic acids are interconverted in humans via 7-ketolithocholic acid, bile acid metabolism was studied in the nutria (Myocastor coypus), the bile of which is known to contain these three bile acids.
(5) Larval Echinococcus multilocularis was found in a nutria (Myocastor coypus) on a fur farm situated south of the Thuringian Forest near the border the Federal Republic of Germany.
(6) A nuclear staining was prominent in zygotene and pachytene spermatocytes in the mouse, weak in the nutria, but absent in gerbil and guinea pig.
(7) Of 35 nutria (Myocaster coypus) at a city zoo, 20 died or were killed because of a progressive central nervous system disease.
(8) Digestibilities of feed, and transit and retention time of fluid and particle digesta marker measured in nutrias (Myocaster coypus) and guinea-pigs (Cavia porcellus) fed on a diet containing 50% alfalfa.
(9) Diseases in farm raised nutria (Myocastor coypus) often depend on hygienic fatalities in the different housing systems of the farms.
