A study was conducted on elk (Cervus canadensis nelsoni) in the Selway-Bitterroot Wilderness and adjoining primitive area of the Clearwater drainage of Idaho over a 3 year period, 1969-1972.
Midwinter examination of cows in this herd indicated the pregnancy rate was high, but game counts showed only 15 to 20 calves per 100 cows indicating that the losses occurred around or after calving.
A serologic survey did not indicate the presence of antibodies to the agents of brucellosis, leptospirosis, vibriosis, bluetongue, infectious bovine rhinotracheitis or bovine virus diarrhea. Positive complement fixation reactions for anaplasmosis were present in nearly 50% of the animals tested; however, many of the serums were anticomplementary.
Blood chemistry determinations were made on all elk and compared with the values obtained from captive elk. Similar values were noted in the captive and wild elk in calcium phosphorous ratio, glucose and total protein. Dissimilarity occurred with cholesterol, blood urea nitrogen, albumen, bilirubin, alkaline phosphatase and serum oxalacetic transaminase values.
