The article is devoted to the study of the density dependence of the horns tissue on the species and the age of the representatives of the deer family. In scientific literature this problem was covered partially. Basic physical parameters (mass, volume, and density) of horns from red deer (Cervus elaphus), fallow deer (Dama dama), European (Capreolus capreolus) and Siberian roe deer (Capreolus pygargus) were estimated. The present study was designed to analyze the results for making identification of species and age of the animal possible.

엘크 사슴고기(Elk deer, Cervus elaphus andadensis)에서 생산된 등심(T1)과 뒷다리살(T2)에 대한 품질 특성을 파악코자 실시되었으며 분석 결과는 다음과 같다. T2가 T1보다 수분 함량은 낮고, 단백질 함량은 높았으며, 전단가는 낮고 보수력은 높았다. 육색 측정 결과 T1 및 T2간 명도, 적색도, 황색도 모두 유의적인 차이가 없었다. 조직특성 조사에서 경도, 부착성, 검성 및 파쇄성은 유의적인 차이가 있었으나, 응집성과 탄력성은 유의적인 차이가 없었다. 지방산 분석결과, SFA와 UFA는 두 부위 간 유의적인 차이가 없었으나 EFA는 T1이 유의적으로 높았다.

본 연구는 급여사료의 단백질 수준과 고단백질 사료의 급여시기가 레드디어의 녹용생산성에 미치는 영향을 검토하기 위해 급여사료의 단백질 수준을 13%(LL구)와 19%(HH구)로 달리하였으며 또한 단백질 함량 19%의 사료 급여시기를 각각 낙각 전(HH구)과 낙각 시점(LH구)으로 달리하여 사양실험을 실시했다. 녹용의 주간 둘레는 상대, 중대 및 하대 부위의 둘레를 합산한 평균치로서 1998년과 1999년의 실험 모두 HH구에서 가장 높았으나 나머지 두 처리구와의 사이에 유의적인 차이는 인정되지 않았다(P>0.05). 녹용의 주간 길이 역시 2년간의 실험에서 모두 HH구가 가장 길었고 LH구가 가장 짧았으나 유의성(P>0.05)은 인정되지 않았다. 급여사료의 단백질 수준에 따른 처리간의 차이는 인정되지 않았으나 녹용의 주간 둘레와 길이는 각각 녹용생산에 밀접한(P<0.01) 관계가 있는 것으로 분석되었다. 녹용생산성에 있어서는 1998년의 경우 HH구가 평균 2,600$\pm$1,000g으로서 가장 높았고 LH구가 2,287$\pm$826g으로 가장 낮은 생산성을 나타냈으나 처리간의 유의성(P>0.05)은 인정되지 않았다. 1999년의 실험에서도 HH구가 평균 3,038 $\pm$867g으로 가장 높은 생산성을 보였으며 LH구가 2,739$\pm$1,079g으로 가장 낮은 생산성을 나타냈으나 역시 처리간에 유의성은 인정되지 않았다. 일당 녹용생산량은 1998년의 경우 HH구가 43$\pm$16g으로 가장 높았고 LH구가 38$\pm$15g으로 가장 낮았으나 처리간의 유의성은 인정되지 않았다. 또한 1999년의 실험에서도 같은 경향이 나타났다.

Objective: Molecular cloning and bioinformatics analysis of annexin A2 (ANXA2) gene in sika deer antler tip were conducted. The role of ANXA2 gene in the growth and development of the antler were analyzed initially. Methods: The reverse transcriptase polymerase chain reaction (RT-PCR) was used to clone the cDNA sequence of the ANXA2 gene from antler tip of sika deer (Cervus Nippon hortulorum) and the bioinformatics methods were applied to analyze the amino acid sequence of Anxa2 protein. The mRNA expression levels of the ANXA2 gene in different growth stages were examined by real time reverse transcriptase polymerase chain reaction (real time RT-PCR). Results: The nucleotide sequence analysis revealed an open reading frame of 1,020 bp encoding 339 amino acids long protein of calculated molecular weight 38.6 kDa and isoelectric point 6.09. Homologous sequence alignment and phylogenetic analysis indicated that the Anxa2 mature protein of sika deer had the closest genetic distance with Cervus elaphus and Bos mutus. Real time RT-PCR results showed that the gene had differential expression levels in different growth stages, and the expression level of the ANXA2 gene was the highest at metaphase (rapid growing period). Conclusion: ANXA2 gene may promote the cell proliferation, and the finding suggested Anxa2 as an important candidate for regulating the growth and development of deer antler.

Comparative studies of histopathologic lesions from 23 purified protein derivative (PPD) positive cattle, 21 slaughter cattle found with tuberculosis, and 11 tuberculosis-positive elk (Cervus elaphus) were performed. PPD positive cattle did not show specific histopathologic lesions in all 23 heads that were no visible lesion reactor. Slaughter cattle found with tuberculosis revealed microscopically classical granulomatous lesion (tubercle) with central caseous necrosis surrounded by mantle of epithelioid cells and Langhan's giant cells capsuled by connective tissue in lung. Elk was noted with some different lesion patterns with classical granulomatous lesion and suppurative abscesses that was composed of fibrin, degenerated cells without having connective tissue. In addition, many Langhan's giant cells infiltration in alveoli at peripheral lesion were observed in some cases of classical granulomatous lesion and suppurative abscesses.

A thirty-five week old elk was referred for Chronic Wasting Disease (CWD) confirmation from Chungnam province in Korea. Necropsy revealed much bloody contents in the lumen of small and large intestines, and reddening of its mucosa. Microscopically, few coccidia showing various developmental stages were infiltrated in lamina propria of small intestine with granulomatous inflammation and congestion. They were identified as Eimeria spp. according to their location and morphological characteristics. Because fecal examination and oocyst culture were not available, the species of the Eimeria could not be confirmed. There were no detection of pathogenic bacteria such as clostridia and virus in intestinal contents. CWD was shown to be negative in immunohistochemistry test. In conclusion, it was the first Eimeria case detected in small intestine of Korean domestic elk as far as we know although Eimeria spp. were not the main cause of death.

Angiotensin I-converting enzyme (ACE) inhibitory activities of elk antler hydrolysates prepared with three kinds of proteases, pepsin, trypsin and $\alpha-chymotrypsin$, were investigated. The ACE inhibitory activity of the pepsinolytic hydrolysate was the highest with an $IC_{50}$ value of $9.3\mu g/mL.$ In addition, three kinds of pepsinolytic hydrolysates with relatively high molecular weights (over 10,000 Da), medium molecular weights (5,000 to 10,000 Da), and low molecular weights (below 5,000 Da) were fractionated using an ultrafiltration membrane system. The below 5,000 Da hydrolysate exhibited the highest ACE inhibitory activity. These results indicate that the pepsinolytic hydrolysates of elk velvet antler could be a good source of peptides with ACE inhibitory activity.

The objective of this study was to evaluate the effect of spent mushroom substrate (SMS) derived from Pleurotus eryngii on the hematological and biochemical blood properties of elk. A total of 18, two and three-year-old elk were fed three different levels of SMS (0, 15 and 20%) in a corn-wheat bran diet for 80 days. The results indicated significantly high levels of blood monocytes, hemoglobin (Hb), and hematocrit (HCT) in elk fed 15% or 20% SMS (p<0.05) compared to control animals. Serum blood urea nitrogen (BUN) and glucose concentrations were also significantly elevated in elk fed both 15% and 20% SMS. The inclusion of SMS in the elk diet did not affect serum total cholesterol, triglyceride, or low density lipoprotein (LDL)-cholesterol concentrations; however, high density lipoprotein (HDL)-cholesterol concentration was significantly increased in SMS-fed groups. In addition, 20% SMS in the diet increased serum iron and testosterone concentrations in elk. These results indicate that adding SMS to the diet of elk can increase their Hgb, serum BUN, glucose, and HDL-cholesterol concentration; therefore, diets containing SMS may enhance the physiologic condition of elk during growth.
