rumen function in red deer, hill sheep and reindeer in the scottish deer, sheep and reindeer grazing on their normal hill ranges were examined at intervals over a period of four years. samples from the digestive tract were taken at different seasons and processed in the field. the red deer and reindeer were killed before samples were taken; rumen samples from the sheep were taken by stomach tube, but a number of animals were also killed at different seasons to correlate stomach tube and whole rumen samples. the animals sampled were representative of the gene ...197610575

a serologic survey of mule deer and elk in utah.sera from mule deer (odocoileus hemionus) and elk (cervus canadensis) in central and northern utah were tested for the prevalence of antibodies to 11 diseases communicable to man or domestic livestock. antibodies to francisella tularensis (at 1:20) were found in 47 of 88 (53.4%) elk and 1 of 89 (1.1%) deer. a screening slide agglutination test for titers to brucella (at 1:20) showed two reactors in elk but none in deer sera. no positive antibody titers were obtained in tests for anaplasmosis, co ...1978105153
sarcocystis in free-ranging herbivores on the national bison range.heart, esophagus, diaphragm and skeletal muscle obtained from various herbivores on the national bison range were examined grossly for sarcocystis. sarcocystis was found in 81, 50, 50, and 13% of the mule deer, (odocoileus hemionus), white-tailed deer (o. virginianus), elk (cervus elaphus), and bison (bison bison), respectively.1979110949

an outbreak of malignant catarrhal fever in red deer (cervus elephus).nine of 15 housed red deer developed an acute disease. six died and three were killed when severely affected. the clinical and post mortem changes suggested a diagnosis of malignant catarrhal fever (mcf) which was consistent with the pantropic lymphoproliferative histopathological lesions observed. attempts to isolate an agent or transmit the condition to cattle failed. the relation of the vasculitis to the pathogenesis of the disease and the susceptibility of red deer are discussed.1979572110

observations on the calving of free-ranging tame red deer (cervus elaphus).calving was observed in 27 farmed red deer, most of which were calving for the first time. on average, parturition lasted 107 min and the placenta was released 98 min after calving. the postnatal development of 23 calves was watched. on average, the first sucking occurred 33 min after birth and the calves were able to stand 47 min after birth. there was wide variation in these times. male first calves had a mean weight of 6.59 kg and females a mean weight of 6.00 kg, weighed dry after the first ...1978722677
heterozygosity in yellowstone park elk, cervus canadensis.protein products of 24 loci from the genomes of yellowstone park elk were analyzed by electrophoresis. heterozygosity was detected in only one system, making elk much less polymorphic than eastern whitetailed deer. data for several other large mammals are compared with those for elk and reveal similarly low levels of isozymic variation. the data are consistent with the fine-grained niche theory but difficult to reconcile with bottlenecks and genetic drift.1978728058

rumen micro-organisms in red deer, hill sheep and reindeer in the scottish highlands.the micro-organisms in rumen samples from red deer, hill sheep and reindeer grazing their natural pastures in the scottish highlands were examined at different seasons over a number of years. the total counts of bacteria and protozoa varied with the seasons, and were lowest in winter when fermentative activity was also at its lowest. as is usual in roughage-fed ruminants, viable counts were only a very small proportion of the total counts. the reindeer rumens had the highest concentrations of ba ...1976981241
[cardiac component of emotional stress in the elk, alces alces, and the reindeer, rangifer tarandus].using radiotelemetric technique, extraordinary changes have been found in cardiac activity of the elk and reindeer during spontaneous emotional stress under natural conditions. cardiac reaction is characterized by rapid 2--3-fold increase in the heart rate and by 3--4-fold increase in the amplitude of t-wave. it was suggested that these changes are associated with abnormalities of metabolic processes in the heart.1976988696
spontaneous aorta and coronary lesions in mountain mammals. i. the carpathian deer (cervus elaphus).arterial lesions were investigated in 48 adult wild carpathian deers (cervus elaphus). aortas from 36 animals and fragments from the main coronary trunks of all the animals were studied histologically and histochemically. in 44.4% of the animals the specimens studied presented gross intimal lesions in the aorta consisting histologically of fibrous plaques (especially situated in the thoracic segment) and/or intimal musculo-elastic thickenings with lipid deposits or fatty streaks (especially in t ...1976989179
