  • Two experiments were conducted to compare digestibility of 12 diets in sheep, red and fallow deer. No differences (p>0.05) between sheep, red and fallow deer in digestibility of dry matter, organic matter and digestible energy content for all diets were found except for the sorghum diet and medic hay. Sheep and fallow deer digested the sorghum diet better than red deer. An in vitro study showed that sheep had a lower in vitro dry matter digestibility and digestible energy content than both red and fallow deer, with a significant interaction between animal species and feed ingredient. Deer digested straws and hays better (p<0.05) than sheep. In vitro digestibility was lower (p<0.05) than in vivo digestibility, but significantly correlated with in vivo digestibility for red and fallow deer. The in vitro method for digestibility estimation has potential as a rapid feed evaluation system for deer, but needs further validation.

  • Under a typical Mediterranean environment in southern Australia, the evaporation rate increases significantly in hot summers, resulting in highly saline drinking water for grazing animals. Also in the cropping areas, dryland salinity is a problem. Grazing animals under these environments can ingest excessive amount of salt from feed, drinking water and soil, which can lead to a reduction in growth rate. To understand the impact of high salt intake on grazing deer, two experiments were conducted to assess the effect of salt levels in drinking water on feed intake and growth rate of red and fallow weaner deer. The results revealed that fallow deer did not show any abnormal behaviour or sickness when salt level in drinking water was increased from 0% to 2.5%. Feed intake was not affected until the salt content in water exceeded 1.5%. Body weight gain was not affected by 1.2% salt in drinking water, but was reduced as salt content in water increased. Compared with deer on fresh water, the feed intake of red deer on saline water was 11-13% lower when salt level in drinking water was 0.4-0.8%. An increase in salt level in water up to 1% resulted in about a 30% reduction in feed intake (p<0.01). Body weight gain was significantly (p=0.004) reduced when salt level reached 1.2%. The deer on 1% salt tended to have a higher (p=0.052) osmotic pressure in serum. The concentration of P, K, Mg and S in serum was affected when salt level in water was over 1.0%. The results suggested that the salt level in drinking water should be lower than 1.2% for fallow weaner deer and 0.8% for red weaner deer to avoid any reduction in feed intake. Deer farmers need to regularly test the salt levels in drinking water on their farms to ensure that the salt intake of grazing deer is not over the levels that deer can tolerate.

  • In Australia, many cropping areas are affected by salt. In these regions, Chenopodiaceous plants, such as Atriplex, Kochia and Bassia spp have been planted to improve soil conditions. These plants have become invaluable feed resources for grazing animals in dry summers, but have a high sodium content. To assess the impact of high salt intake on grazing deer, two experiments were conducted. The first experiment used 30 fallow weaner deer to examine the effect of salt level in the diet on feed intake, water intake and body weight of fallow deer. Salt was added to lucerne chaff at 0, 1.5, 3.0, 4.5 and 6% and fresh water was offered all the time. Increasing the salt level in the diet from 0 to 6% didn't affect feed intake, osmotic pressure and mineral concentration in blood of fallow deer. However, water intake was significantly higher (p<0.05) in deer fed diets containing more than 3% salt. Body weight was lower (p${\leq}$0.056) for fallow deer in July and August when salt content was over 3%, suggesting they can ingest over 15 g sodium/day without significant depression in both feed intake and growth rate if the fresh water is available. In the second experiment, 18 red weaner deer were fed lucerne chaff diets containing 1.5, 4.5 and 6.0% salt with 6 deer/diet. The results revealed that feed intake and blood osmotic pressure were similar (p>0.05) for red deer fed different levels of salt although the feed intake declined from 1.91 to 1.67 kg with the increase of salt level from 1.5% to 6.0% in the diet. Water intake was significantly higher for deer fed diets containing over 4.5% salt, but there was no difference in body weight during the experiment. However, no recommendation can be made on the salt tolerance of red deer due to limited increment of salt level in the diet.

  • Hypoderma spp. larvae cause subcutaneous myiasis in several animal species. The objective of the present investigation was to identify and characterize morphologically and molecularly the larvae of Hypoderma spp. collected from cattle (Bos taurus taurus) and red deer (Cervus elaphus) in the district of Castelo Branco, Portugal. For this purpose, a total of 8 larvae were collected from cattle (n=2) and red deer (n=6). After morphological identification of Hypoderma spp. larvae, molecular characterization was based on PCR-RFLP and mitochondrial CO1 gene sequence analysis. All larvae were morphologically characterized as the third instar larvae (L3) of H. actaeon. Two restriction enzymes were used for molecular identification of the larvae. TaqI restriction enzyme was not able to cut H. actaeon. However, MboII restriction enzyme differentiated Hypoderma species showing 210 and 450 bp bands in H. actaeon. Furthermore, according to the alignment of the mt-CO1 gene sequences of Hypoderma species and to PCR-RFLP findings, all the identified Hypoderma larvae were confirmed as H. actaeon. This is the first report of identification of Hypoderma spp. (Diptera; Oestridae) from cattle and red deer in Portugal, based on morphological and molecular analyses.

  • Thirty farmers, representing three major deer counties in Kyung-Kee province and 50 farmers scattered in Chung-Buk province were interviewed to determine the current status of the Korean deer industry. Items surveyed were general information, farmed deer breeds. farm facilities, feeding and nutrition, hygiene and disorder incidence, velvetting, income sources, products and their sale, management problems and herd size control. The 888 deer farmed in Kyung-Kee province included spotted deer (Cervus nippon. 69.4%), red deer (Cervus elaphus, 6.1%), wapiti (Cervus elaphus canadensis, 12.2%), spotted $\times$ red deer hybrids (6.2%), red deer $\times$ wapiti hybrids (4.6%). and fallow deer (Dama dama, 1.5%). Poor information on feeding was evidenced by wide variation among farms of daily feed supply and ratios of forage to concentrate, and poor nutritional considerations according to physiological status of deer. Hygiene needed more attention. The incidence of diseases and disorders was high: enteritis (73.3% in Kyung-Kee province), fractures (60.0%), and dystocia (56.7%). The major source of farm income was velvet antler and its blood. To improve productive efficiency, attention should be given to improving farm facilities, simplified product marketing, developing standard feeding system, and economic grazing system.

  • Hematopoietic stem cells in bone marrow form all kinds of blood cells. In traditional medicine, functions of bone marrow cells are very similar to those of Essence(精) which is a fundamental factor of physical development and reproduction. Our experiment examined the effect of deer blood on aplastic anemia induced mouse using cyclophosphamide 150 mg/kg i.p injection before experiment and then another cyclophosphamide 120 mg/kg i.p injection on day 10. Then we administrated dried deer blood in distilled water for 5 days, 9 days and 10 days. We examined blood and marrow samples. In results, deer blood showed a trend of effectiveness on recovery of red blood cells and erythropoietin although they were not statistical significant. And deer blood did not show changes in CD34.

  • This study was performed to evaluate the hemopoietic effects of 6 species of deer antlers from origins and parts in vitro. CD34 positive cells were isolated and confirmed the its population by FACS analysis. In a week liquid culture, there was any statistical significance between extracts of three parts of six species of deer antlers in the experiments as colony forming assay, proliferation assay, differentiation assay and observation of morphology. However, after 2 weeks- culture with extracts of three parts of six species of deer antlers, colonies were counted. six species of deer antlers, such as middle part of Korean nippon deer, upper part of Chinese nippon deer, upper part of Newzealand horse deer, middle part of Korea horse deer and middle part of Newzealand red deer, significantly increased the CFU-GM (colony forming unit garnulocyte-macrophage) of CD34 positive cells re1atεd to production of leucocytes such as eosinophil, basophil and neutrophil, while only middle part of Korea horse deer significantly increased the BFU-E (burst forming unit-erythroid) at 1 mg/ml seggesting progenting red blood cells (RBC). In the molecular study with CD34+ cells pretreated with cyclophosphamide, antagonist of hemopoietic activity, upper Part of Korean nippon deer and upper part of Chinese nippon deer effectively increased TPO involved in a late pathway of hematopoiesis just like in ELISA assay of IL-3, TPO and GM-CSF. Taken together, these results indicate exσacts of deer antler had some hemopoietic activity still proposing more clinical study and more basic mechanism research.

  • This study was conducted to elucidate the influence of recombinant bovine somatotropin (rBST) on the plasma IGF-I profiles in deer stags. Slow release rBST (250mg each) preparations were injected subcutaneously during the antler's non-growing period and growing period. It was observed that significant increases in the plasma IGF-I concentrations were occurred right after injections of the rBST irrespective of antler's non-growing period or growing period. When the rBST preparations were injected two times with one week interval during the antler's non-growing period, the mean level of IGF-I was found to be 2,920.7ng I mL, indicating that the IGF-I concentration increased up to 8.4-folds compared with a control. After two weeks from second shot, however, the IGF-I levels decreased to the level of the control. Similar results were also obtained with both a Sika and a Red deer during the antler's growing period. Increases in the IGF-I level of up to 5.6-folds with the Sika deer and 4.3-folds with the Red deer were found. Based on the present study, it is likely that the rBST may be used as a possible candidate for an antler's growth stimulating agent.
