AbstractParasitism in wild mammals can vary according to myriad intrinsic and extrinsic factors, many of which vary seasonally. However, seasonal variation in parasitism is rarely studied using repeated samples from known individuals. Here we used a wild population of individually recognized red deer (Cervus elaphus) on the Isle of Rum to quantify seasonality and intrinsic factors affecting gastrointestinal helminth parasitism over the course of a year. We collected 1020 non-invasive faecal samples from 328 known individuals which we then analysed for propagules of three helminth taxa: strongyle nematodes, the common liver flukeFasciola hepaticaand the tissue nematodeElaphostrongylus cervi. Zero-inflated Poisson models were used to investigate how season, age and sex were associated with parasite prevalence and count intensity, while Poisson models were used to quantify individual repeatability within and between sampling seasons. Parasite intensity and prevalence varied according to all investigated factors, with opposing seasonality, age profiles and sex biases between parasite taxa. Repeatability was moderate, decreased between seasons and varied between parasites; bothF. hepaticaandE. cervishowed significant between-season repeatability, while strongyle nematode counts were only repeatable within-season and showed no repeatability within individuals across the year.

Pharmacological Method

The aim was to estimate the effective pharmacological method of the estrous cycle synchronization by checking the effects of synchronization by measurement of progesterone (P4) and 17-beta estradiol (E2) concentration by RIA and artificial insemination. The experiment was performed at the red deer farm in Rudzie (North-East Poland; 3 year’s old). The herd (N = 14) was kept away from bulls and was divided in two groups of seven animals. In the Group I, CIDR insert (0.3 g of P4) was applicated intravaginally for 12 days; a second insert replaced the first one for the next 12 days, and next 200 IU of equine chorionic gonadotropin (eCG) was injected intramuscularly (Folligon). Estrus was expected 48 h after eCG injection. In the Group II, Chronogest sponge (20 mg of flugestone acetate) was applicated intravaginally and after 7 days replaced with second chronogest sponge for 7 days. After removing the sponge, on the same day eCG was injected and estrus was expected after 48 h. Artificial insemination was provided with frozen-thawed semen twice: 12 and 24 h after expected estrus. The peripheral blood from the jugular vein was collected each time when the inserts or sponge were applicated and 40 days after insemination. The concentration of P4 and E2 in plasma was measured by RIA. The effectiveness of insemination was monitored by pregnancy-associated glycoproteins determination and observed by the number of calves born. Two pregnancies were confirmed in Group I and five in Group II based on PAG concentration. One newborn was observed in Group I and five in Group II. Both methods of synchronization are effective in hinds based on the received profile of steroids. Although the sponge shape in case of chronogest is better comparing with CIDR, which was not completely deposited in the vagina of hind, potentially leads to bacteria inflammation, and it disturbs the rightful endocrine regulation. Moreover, pregnancy rate and hormone responsiveness were better in Group II.

Mesenchymal stem cells positive to surface antigen STRO-1 were isolated from regenerating antlers of red deer (Cervus elaphus) and fallow deer (Dama dama) using a magnetic-activated cell sorting (MACS) method. In this study we analysed factors potentially affecting the number of STRO-1+ cells in the cell cultures. With regard to the STRO-1 antigen, we evaluated data from 188 MACS separation procedures of cell cultures cultivated in Dulbecco’s Modified Eagle Medium and 10% fetal calf serum of four fallow deer males (130 procedures) and four red deer males (58 procedures). The analysed factors were the sampling site of the antler or the pedicle, cell passage and type of the cell culture (mixed or STRO-1 negative cell cultures). The percentage of obtained STRO-1+ cells varied greatly from 0.4 to 38.9% for fallow deer and from 1.8 to 16.5% for red deer. We have not found any significant influence of the sampling site. The passage and the type of culture were significant factors for both fallow and red deer cells. The highest numbers of STRO-1+ cells were obtained from the second passage from both fallow and red deer cell cultures (24.6 and 5.5%, respectively). Our experiment revealed that we can maximise the number of STRO-1+ cells in the cultures by manipulating the cultivation factors.

AbstractGenetic and phenotypic parameters were estimated for farmed red deer (Cervus elaphus) in an upland environment in the north-east of Scotland. Genetic parameters were estimated using restricted maximum likelihood analyses. Heritabilities of pre-weaning traits associated with growth were moderate for birth weight (0·27 (s.e. 0·04)), weaning weight, generally in September at 3 months of age (0·21 (s.e. 0·06)) and growth rate from birth to weaning (0·15 (s.e. 0·03)). Heritabilities for post-weaning traits were 0·10 (s.e. 0·05) for turn-out weight in April/May, 0·14 (s.e. 0·06) for September weight, at 15 months of age, 0·08 (s.e. 0·05) for growth rate weaning to turn-out and 0·12 (s.e. 0·06) for growth rate turn-out to September. Correlations between weaning weight and post-weaning traits were high indicating the usefulness of weaning weight as a selection criterion for red deer on upland farms. While Wapiti (Cervus elaphus canadensis) crosses grew faster than pure red deer they also tended to have higher mortality rates pre-weaning. Older dams were more likely to have a successful pregnancy and also tended to calve earlier. Date of calving was found to show no heritable variation in this study.
