To increase the extraction yield and biological effect of antler by fermentation, probiotics fermenting antler were screened from rice shells. Of screened Bacillus species, the most potently antler-degrading probiotics was Bacillus KH-07. The supernatant yield of fermented antler is highest. Bacillus KH-07 may belong to Bacillus licheniformis by biochemical and 16S rDNA sequencing analyses. The KH-07-fermented antler (50 mg/kg) increased the anti-fatigue effect 2.3-fold compared to that of non-treated antler. Furthermore, the KH-07-fermented antler improved $CCl_4$-induced liver injury in mice. Based on these findings, the extraction yield and biological effect of antler can be increased by KH-07 fermentation.

The deer antler has been used as a major drug in oriental medicine for a long time. Recently, the demand for easy-to-take health functional foods is increasing due to economic development and changes in diet. As part of research on the development of functional materials for antlers, lactic acid fermentation of antler extract was performed. It was intended to develop a functional material with enhanced total polyphenol and flavonoid content and enhanced antioxidant activity. Lactic acid bacteria fermentation was performed by adding 4 types of lactic acid bacteria starter products, B. longum, Lb. Plantarum, Lb. acidophilus and mixture of 8 types of lactic acid bacteria to the antler water extract substrate, respectively. During the fermentation of lactic acid bacteria, the number of proliferation, total polyphenol and total flavonoid content, DPPH radical scavenging and antioxidant activity were quantified and evaluated. As a result of adding these four types of lactic acid bacteria to the antler water extract substrate, the number of lactic acid bacteria measured was 2.04~5.00×107. Meanwhile, a protease (Baciullus amyloliquefaciens culture: Maxazyme NNP DS) was added to the antler extract to decompose the peptide bonds of the contained proteins. Then, these four types of lactic acid bacteria were added and the number of lactic acid bacteria increased to 2.84×107 ~ 2.21×108 as the result of culture. The total polyphenol contents were 4.82~6.26 ㎍/mL in the lactic acid bacteria fermentation extracts, and after the reaction of protease enzyme and lactic fermentation, increased to 14.27~20.58 ㎍/mL. The total flavonoid contents were 1.52~2.21 ㎍/ml in the lactic acid bacteria fermentation extracts, and after the protease reaction and fermentation, increased to 5.59 ~ 8.11 mg/mL. DPPH radical scavenging activities of lactic acid bacteria fermentation extracts was 17.03~22.75%, but after the protease reaction and fermentation, remarkably increased to 32.82~42.90%.

This study was performed to investigate the blood contents of velvet antler and femoral venous blood in farmed elk (Cervus canadensis). Blood samples were collected from 12 young adult elk (3.5-4.5 years old) with a mixture of fentanyl-azaperone-xylazine (Fentazine$^{(R)}$). Values for hematological and clinicochemical components of the clinical healthy elk were determined. The results were grouped for comparison according to velvet antler and femoral venous blood. Lower mean platelet counts and fibrinogen values were found in the velvet antler than femoral venous blood (p<0.01). White blood cell count of velvet antler was significantly higher than that of femoral venous blood 0<0.05). The clinicochemical parameters (total protein, albumin, globulin, alanine aminotransferase, aspartate aminotransferasei blood urea nitrogens calciums magnesium and phosphonls) obtained in this study far farmed elk are consistent with the values between velvet antler and femoral venous blood.

The effect of deer antler extract on muscle differentiation and muscle atrophy were evaluated to minimize muscle loss following aging. Various deer antler extracts (HWE, hot water extract of deer antler; FE, HWE of fermented deer antler; ET, enzyme-assisted extract of deer antler; UE, extract prepared by ultrasonication of deer antler) were evaluated for their effect on muscle differentiation and inhibition of 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR)-induced muscle atrophy in C2C12 cells. Morphological changes according to the effect of antler extracts on muscle differentiation were confirmed by Jenner-Giemsa staining. In addition, the expression levels of genes related to muscle differentiation and atrophy were confirmed through qRT-PCR. In the presence of antler extracts, the length and thickness of myotubes and myogenin differentiation 1 (MyoD1) and myogenic factor 5 (Myf5) gene expression were increased compared to those in the control group (CON). Gene expression of AMP-activated protein kinase (AMPK), MyoD1, and myogenin, along with the muscle atrophy factors muscle RING finger-1 (MuRF-1) and forkhead box O3a (FoxO3a) upon addition of deer antler extracts to muscle-atrophied C2C12 cells was determined by qRT-PCR after treatment with AICAR. The expression of MuRF-1 and FoxO3a decreased in the groups treated with antler extracts compared to that in the group treated with AICAR alone. In addition, gene expression of MyoD1 and myogenin in the muscle atrophy cell model was significantly increased compared that into the CON. Therefore, our findings indicate that antler extract can increase the expression of MyoD1, Myf5 and myogenin, inhibit muscle atrophy, and promote muscle differentiation.

The aim of this study was to estimate the factors that can be used as a predictive indicator of antler productivity in elk. Body weight and antler data from 115 stags raised at the Animal Genetic Resources Research Center in Korea were used in this study. The function for the average antler weight was derived by age, which was $y=-3.4693+5.3747x-0.8x^2+0.0424x^3$, and $R^2$ was 0.991. The analysis of the relationship between body weight at birth and the 1st and 2nd year and the antler weight after the 2nd year showed a correlation between them. There was a correlation between the antler weight of 1 and 2 year old stags and the weight of 2 year old stags as well; especially, both antler weights for the 1st and 2nd year were highly correlated with the antler weight of the 4th year. However, there was no relationship between the antler main beam length for the 1st and 2nd year and the antler weight after the 3rd year. Therefore, it is expected that a large amount of antler will be obtained in the future if proper management is carried out for young deer from birth to 2 years old. Additionally, the results of this study are expected to be useful for the development of a deer breeding program and the deer industry.
