The hepatitis E virus (HEV) is a leading causative agent of acute hepatitis in humans. Zoonotic HEV strains have been isolated from several animal species, including pigs. New HEV variants have been recently isolated from camels in the Middle East. In the present study, fecal samples from fallow deer, formosan deer, alpaca, and guanaco were analyzed for the detection of HEV. One HEV strain was detected from guanaco, a species of camelids. The nucleotide sequence of guanaco HEV was identical to those of deer HEV-3 strains, which implied the cross-species transmission of HEV-3 from deer to guanaco.

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.

The alkanes in plant materials can potentially be used as markers to estimate composition and digestibility of diet of deer for the development of feeding strategies, but the analysis of alkanes in plant materials and deer faeces is time-consuming and expensive. In this study, 242 faecal samples and 119 pasture samples were scanned using near infrared spectroscopy (NIR) and the concentrations of alkanes in these samples were analysed to develop calibrations for predicting alkane concentrations in pastures and deer faeces. The $R^2$ values for NIR calibrations were <0.6 for $C_{24}$, $C_{26}$, $C_{32}$ and $C_{36}$, but were >0.8 for other alkanes for faecal samples. The $R^2$ values were >0.87 for alkanes with chains from $C_{27}$ to C35 for pasture samples. However, NIR was unable to predict concentrations of alkanes with chains of $C_{24}$, $C_{26}$, $C_{32}$ and $C_{36}$ in faecal samples and $C_{24}$, C25, $C_{26}$ and $C_{36}$ in pasture samples. While the use of these NIR calibrations will accelerate the estimation of diet digestibility, dietary components and botanical composition of pastures, the influence of the type of pasture on NIR calibration will require further examination.

Hepatitis E virus (HEV) can infect not only human but also several animals. This study has been conducted to evaluate the comprehensive anti-HEV seroprevalence in zoo animals in Korea. Anti-HEV antibodies were identified in 14 of 64 zoo animal species. HEV antibodies were detected for the first time in Eurasian Lynx, Setland Pony, Fallow Deer, Ezo Sika, Formosa Deer, East Wapitis, Barasingha, Corriedale, American Bison, Guanacos, Reticulated Giraffe, and Saanen. These results indicate that the several zoo animal species were exposed to HEV.

토양으로부터 방출되는 $CO_2$의 양은 전 지구적 지구 탄소 순환에서 가장 큰 방출 중 하나로 알려져 있다. 특히 토양 내 미생물의 유기물질 분해 과정에 의해 방출되는 이산화탄소의 양은 토양의 탄소 저장량을 장기적으로 결정하는 요인이 되므로 그 양을 정량화 하는 것이 필요하다. 본 연구는 토양에서 고라니의 분변이 $CO_2$ 배출에 미치는 영향을 파악하기 위해 수행하였다. 그리고 고라니의 분변이 토양의 $CO_2$ 배출에 주는 영향과 토지의 이용에 따라 변화하는 $CO_2$ flux를 정량화 하였다. 그 결과 고라니 분변 내 많은 유기물질은 토양 미생물의 활성화에 영향을 주고 그로 인해 토양의 호흡 및 토양 내 물리 화학적인 변화가 발생되어 토양의 유기물 함량이 서로 다르게 나타남을 확인할 수 있었다. 특히 4개 지역의 토양(경작지, 휴경지, 버드나무 군락, 갈대습지)의 C/N ratio와 $CO_2$ flux는 분변의 유무와 통계적으로 매우 유의미한 상관 관계를 나타냈으며(P<0.01), 분변의 영향을 받은 토양의 $CO_2$ flux는 분변의 영향을 받지 않은 토양보다 2-20배 더 높은 것으로 나타났다. 이 연구는 고라니의 분변이 토양에 주는 영향과 야생동물 분변을 이용한 토양 물질 순환 연구를 통해 육상 생태계 및 토양권의 물질 순환과 그 영향의 정도를 정량화 하였다는 점에서 큰 의의가 있는 연구이다.
