“…Seasonal changes in cortisol secretion have been reported in males of some other seasonally breeding deer species. Cortisol concentrations have been reported to decline during the rut in white-tailed deer (Bubenik et al 1983), reindeer (Nilssen et al 1985) and axis deer (Chapple et al 1991), while other studies have reported increased concentrations during the rut for red deer (Feher et al 1994), or no change in reindeer (Ringberg 1979) and Eld's deer (Monfort et al 1993). The metabolic and reproductive implications of a seasonal rhythm in basal cortisol concentrations in red deer stags are discussed below.…”

“…Evidence for a seasonal rhythm in adrenal activity or responsiveness in deer varies between species and studies, with seasonal changes reported in white-tailed deer (Bubenik et al 1983), reindeer (Rangifer tarandus) (Nilssen et al 1985), axis deer (Axis axis) (Chapple et al 1991) and red deer (Suttie et al 1995, Cassidy 1996 but not in Eld's deer (Monfort et al 1993) or in another study on axis deer (Bubenik & Brown 1989).…”

Seasonal changes in the activity and responsiveness of the adrenal gland in red deer (Cervus elaphus) stags were quantified by measuring 24 h endogenous cortisol secretory profiles and plasma cortisol responses to either administration of exogenous ACTH or a standardised stressor during November (period of velvet growth), February (pre-rut), April (mid-rut) and July (post-rut) (southern hemisphere) using a remote blood sampling device (DracPac).Ultradian rhythms in the concentration of plasma cortisol were observed resulting from the episodic secretion of cortisol from the adrenal cortex at a mean rate of 0·8 pulses/h. Circadian rhythms in plasma cortisol concentrations were also found in 11 out of the 20 complete 24 h profiles (mean amplitude, 3·8 1·4 ng/ml).Seasonal rhythms in mean 24 h plasma cortisol concentrations and cortisol pulse parameters were also observed. Mean 24 h plasma cortisol concentrations were higher in November (12·5 1·0 ng/ml) than in February (6·3 1·0 ng/ml), April (4·0 1·0 ng/ml) or July (4·2 1·0 ng/ml). Cortisol pulse height, nadir and amplitude were all significantly higher in November than at other times of the year (P<0·01).Peak cortisol concentrations following infusion of ACTH 1-24 (0·04 IU kg -1 ) were higher (P<0·05) in November (55·8 2·7 ng/ml) and lower (P<0·001) in April (33·7 1·8 ng/ml) than those in February and July (48·7 2·0 ng/ml and 45·4 2·0 ng/ml respectively). The area under the cortisol response curve was significantly smaller (P<0·05) in April (266·6 15·3 ng/ml/ 190 min) than at other times of the year (February, 366·1 15·3 ng/ml/190 min; July, 340·7 15·3 ng/ml/ 190 min and November, 387·8 21·2 ng/ml/190 min).These data demonstrate that the adrenal gland of the red deer stag exhibits ultradian, circadian and seasonal rhythms in activity, and that its responsiveness to ACTH varies with season. November, a period of reproductive quiescence in the southern hemisphere, with new antler growth and rapid weight gain, is associated with higher mean plasma cortisol concentrations and a greater responsiveness to exogenous ACTH. In contrast, the breeding season is associated with lower adrenal activity and responsiveness.

The aim of the study was to present the serum biochemical values in free-ranging roe deer as useful indicators of the health status of the animal. Blood samples of 63 roe deer (Capreolus capreolus) were collected during regular annual harvest in Slovenia and analysed for biochemical indicators. The following mean values were recorded: aspartate aminotransferase (3 µkat), alanine aminotransferase (0.7 µkat), alkaline phosphatase (1.5 µkat), lactate dehydrogenase (11.8 µkat), gamma glutamyltransferase (1.9 µkat), creatine kinase (16.3 µkat), urea (6.3 mmol/l), creatinine (136.9 μmol/l), total serum proteins (65.5 g/l), cholesterol (4

“…Marco and Lavin (1999) reported significant elevations in serum ALT, total protein, albumin, sodium, and chloride in red deer captured by physical means compared with those from deer that were chemically immobilized. Physically restrained, ''untrained'' chital deer (Axis axis) had elevated serum AST and CK levels, which were attributed to muscle damage sustained by ''excited'' deer that were not used to handling (Chapple et al, 1991). Physical handling and restraint of wild animals elevates serum cortisol levels (Sakkinen et al, 2004), and serum cortisol levels depend on the method of capture, previous experience of the animals, age, and sex (Morton et al, 1995).…”

ABSTRACT:Boreal caribou (Rangifer tarandus caribou) are an ecologically and culturally important wildlife species and now range almost exclusively in the boreal forests of Canada, including the Northwest Territories, northern Alberta, and British Columbia. Boreal caribou are threatened throughout their Canadian range because of direct and indirect natural and anthropogenic factors. In the Northwest Territories, however, they have a continuous range that overall has not yet been subjected to the same degree of anthropogenic habitat fragmentation and degradation that has occurred elsewhere in Canada. To monitor the health of boreal caribou populations and individuals, we collected blood from 104 adult, female boreal caribou captured between March 2003 and February 2006 and measured serum biochemical parameters. Serum creatinine was higher in pregnant than in nonpregnant caribou. Several biochemical parameters differed among years, but they tended to be similar to those reported for reindeer. Serum antibodies were found to an alphaherpesvirus, Toxoplasma gondii, and to the Mycobacterium avium subspecies paratuberculosis in 37.5, 2.9, and 1.3% of boreal caribou, respectively. Fecal samples were collected from 149 boreal caribou, and Cryptosporidium sp. oocysts, Giardia sp. cysts, trichostrongyle ova, dorsal-spined nematode larvae, cestode ova, and Eimeria sp. were found. Trypanosoma sp. was detected in the blood of 72.1% of boreal caribou. Eimeria sp., Cryptosporidium sp., and Giardia sp. have not been previously reported in boreal caribou.
