A compression method indicating fat contents of elk (wapiti) femur marrows

摘要: Chemical analyses may not be feasible for fat content of femur marrows big game animals, and to describe color textures subjectively is difficult except extreme characteristics. It was found that the ether-extractable a marrow related inversely compressibility marrow. A known length reveals its compression this easily measured in percent. The freshly obtained from 291 elk (wapiti) (Cervus canadensis) were at room temperature by method described percent compared identical marrows. amount also mule deer (Odocoileus h. hemionus), pronghorn antelope (Antilocapra americana), moose (Alces cattle. By chemical analysis, varied up 10 between fresh frozen subsamples measuring indicates accurately enough some studies, without delay or laboratory costs. consistency are correlated with alcohol-etherextraction indicate condition white-tailed virginianus) (Cheatum 1949). Marrow good white solid; undernourished gelatinous, yellow red. Riney (1955:435) used system index values various colors permit visual estimation red elaphus). characteristics have limitations assessing black-tailed hemionus columbianus), according Bischoff (1954). He considered only an adequate measure condition. Collections animals provide chemically analyzed grossly examined as criterion Under circumstances analysis femurs feasible. Femur subject variable evaluations among different observers. quantitative devised evaluate 1 contribution Montana Federal Aid Project W-83-R. which determinations repeated same person, well duplicated other persons.
