“…Thus prolonged and repeated manual handling as such appears to be the most important factor producing stress lesions. Consequently, in reindeer, mental stress, sheer fear as reported in pigs (Johansson et al, 1982) and seen in restrained (Ader, 1971;Franzmann et al, 1975) or trapped animals (Iversen et al, 1972;Jacobson et al, 1978) appeares to be the most significant factor in the development of stress induced lesions.…”

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 "cottontail" type rabbits (Jacobson et al 1978), the impact of the seasons on the quantity of peripheral blood elements was high, since higher values of neutrophil granulocytes were observed in such animals in summer as compared to autumn, and in winter and spring as compared to summer. In the case of acidophil granulocytes in such animals, higher values were observed in summer, as compared to autumn and winter (Jacobson et al 1978).…”

The objective of the study was to determine values of apoptosis for peripheral blood lymphocytes and granulocytes, including dependency on the season of the year, in Polish mixed-breed rabbits and in mixed-breed rabbits with the addition of blood of meat-breed rabbits. The study was carried out in four seasons of the year (spring, summer, autumn, winter) involving 120 Polish mixed-breed rabbits -group I, and 120 Polish mixed-breed rabbits with addition of meat-breed rabbit blood -group II. Assessment of apoptosis of lymphocytes and granulocytes was performed using as FACScan cytometer by Becton Dickinson with FACSDiva software (USA), using as ApoFluor ® Green Caspase reagent kit (MP Biomedicals, USA) to detect the activity of the total caspase pool 1, 3, 4, 5, 6, 7, 8, 9 in granulocytes and lymphocytes of rabbit peripheral blood. The results for apoptosis of lymphocytes and granulocytes in peripheral blood in the animals investigated (group I and II) were subjected to statistical analysis with the t'Student test at p=0.05. It was noted that, in rabbits from group I, the values for apoptosis of lymphocytes were the highest in winter and autumn (36.02% and 31.24%, respectively), and the lowest in spring and summer (26.73% and 22.72%, respectively), whereas in the case of granulocytes the highest values were in summer and spring (14.69% and 12.95%, respectively), and the lowest in winter and autumn (8.16% and 8.57%, respectively). In mixed-breed rabbits with the addition of meat-breed blood (group II), the values for apoptosis of lympocytes were the highest in spring (29.13%), and the lowest in summer (25.43%); whereas in the case of granulocytes the highest values were in summer and spring (14.0% and 11.15%, respectively), and the lowest in autumn and winter (7.46% and 7.64%, respectively).
