“…The animals of Groups I and III showed the same magnitude of ASAT activity as reported by Bjarghov et al (1976) and by Nieminen (1980). The experimental animals showed a higher activity at both sampling occasions with a pronounced increase between the two sampling events.…”

Abstract:The general mechanism and biological effects of stress are dealt with. Investigations performed on semidomesticated reindeer concerning the stress response under different herding and management conditions are presented and discussed.The findings indicate that: Reindeer are susceptible to management stress and that their degree of tameness plays an important role in the development of stress lesions such as muscular and myocardial degeneration and abomasal haemorrhages, etc.The animals are not favoured by rests between events of stress exposure as the effects produced tend to be cumulative.Depletion of muscular glycogen stores, increased catabolism of muscular protein, muscular degeneration and increased blood-urea levels can not be excluded as a cause of an altered and bad taste of the meat, i.e. a bad meat quality.Thus prolonged and repeated manual handling and transportation of live animals should be avoided. The use of helicopters or other motor vehicles must be correlated to the tameness of the animals and to environmental conditions. Stress due to incorrect management methods may, by means of stress induced lesions, severly affect the productivity of reindeer.

“…In contrast, DelGuidice et al [18] described seasonal variations in total protein that are similar to the pattern observed in our study. According to these authors, those changes were related to changes in diet, as in other studies [5,19,20]. According to our results, the minimum plasmatic protein values occurred in spring and summer while antler growth was taking place [9].…”

Abstract:The aim of this study was to assess the time trend of plasmatic proteins in red deer stags. Blood samples were taken monthly from 17 male red deer for 22 months. Total plasmatic determination and protein electrophoresis were performed. Plasmatic proteins showed minimum values during spring and summer and a maximum at the peak of the mating period. Total globulins, β and γ, followed a pattern similar to that observed for total proteins, whereas α1 and α2 globulins showed no seasonal variations. Albumin showed higher values in early spring and summer and lower values at the beginning of autumn, coinciding with the mating season. These seasonal changes in plasmatic proteins should be taken into account when assessing blood protein analysis results.

“…Hyvarinen et al (1977) and Nieminen and Timisjarvi (1983) report serum Ca values from reindeer slaughtered in October and February (2.3-2.8 mmol/1) that correspond well with the values we have from the winter 79/80. Serum Ca values reported by Bjarghov et al (1976) from lichen-fed reindeer are at the same level. Our values from the second year, 80/81, are slightly higher with a maximum at 3.3 mmol/1.…”

“…Most of the reindeer kept their serum-Mg values within the normal range while some had very low values (down to 0.2 mmol/1). In reindeer fed lichens for 4 months, Bjarghov et al (1976) report similar Mg-levels. As in our study no symptoms of tetany were seen in the animals.…”

Samples of blood, rumen, and caecal contents were taken from 238 reindeer (Rangifer tarandus) slaughtered between September and March in two consecutive years. Levels of magnesium, calcium and phosphorus were measured to evaluate the extent to which levels of these minerals reflected changes in the grazing conditions through the winter. Twenty-one reindeer in poor conditon were included in the investigation and compared with normal animals with respect to the investigated minerals.Serum values in September were within the normal range for domestic sheep (Ovis spp.) and cattle (Bos spp.) (Church, 1979). Magnesium was 0.9±0.1 mmol/1, calcium 2.8 ± 0.3 mmol/1 and phosphorus 2.5 ± 0.5 mmol/1. Calcium values did not change very much through the winter while magnesium and phosphorus constantly decreased from September to February. Extremely low serum magnesium values (below 0.3 mmol/1 in some animals w T ere found in January and February. The majority of the animals in poor condition had low serum-magnesium values.
