The large amount of tissue culture medium (TCM), which contains some of the active secretory components of Korean wild ginseng (KWG; Panax ginseng) such as saponins, is usually discarded after harvest of KWG. The present study was aimed to investigate the efficacy of oral administration of the TCM-KWG on growth performance and diseases resistance in broiler chickens. A day old broiler chickens randomized in 6 groups (n = 60/groups) were administered orally with 0, 2, 4, 8, 16 and 32 mL/L TCMKWG through drinking water for 5 weeks and examined the change of weight gain, feed intake and blood components. Also, five weeks old broiler chickens (n = 15/groups) were challenged orally with Salmonella (S.) gallinarum and investigated the mortality in broiler chickens. An average weight gain and feed intake significantly didn't change in TCM-KWG administration groups as compared to control group. The concentration of calcium (Ca), phosphate (Pi) and potassium (K) in serum were increase by TCM-KWG administration in broiler chickens. We also found that oral administration of TCM-KWG through drinking water significantly reduced the mortality in broiler chickens experimentally infected with virulent S. gallinarum. The results of this study indicated that TCM-KWG administration may elevate the resistance on disease and improved the skeleton formation and body homeostasis of chickens, and TCM-KWG can be used as a cost-effective and environmentally alternative additives to control of the disease and growth.

Proteomics is a useful approach to know protein expression, post-translational modification and protein function. We investigated the protein expression pattern and identity in pigs fed with the tissue culture medium waste after harvest of Korean wild ginseng (TCM-KWG) (Panax ginseng). Two groups (n = 30/group) of pigs were administered with 0 (control) and 16 ml/L (treatment) TCM-KWG through drinking water. After 4 weeks, we examined the protein expression pattern of longissimus dorsi muscle by Two-dimensional electrophoresis analysis. TCM-KWG treatment significantly increased two spot's density, and markedly reduced one spot's density in the muscles. We identified 3 proteins (heat shock protein 90-alpha, myosin binding protein and cofilin 2) by the ESI-MS/MS (Q-TOF2, Micromass). These results demonstrate that TCM-KWG treatment may play a protection role against physiological stress in pigs, like as increased heat shock protein 90-alpha.

본 연구에서는 산삼의 조직 배양 후 폐기되는 산삼 배양액을 육계에 음수를 통하여 다양한 농도로 급여한 후 계육의 일반 성분, 물리화학적인 성상 및 이화학적 성상 변화를 분석하여 산삼 배양액의 효능과 첨가제로서의 가능성을 규명하였다. 산삼 배양액을 급여한 육계 가슴육의 수분 함량, 조단백질과 조지방의 함량에 유의적인 차이는 보이지 않았지만 조회분의 함량은 산삼 배양액 32 mL/L 급여군이 다른 처리군에 비하여 유의적으로 증가하는 것을 볼 수 있었다. 또한, 산삼 배양액 급여군에서 육즙 손실, 조리 감량, 전단력과 저장성은 감소되는 경향을 보이나 유의적인 차이는 보이지 않았지만 산삼 배양액 급여군의 가슴육 pH는 유의성 있게 감소하였다. 이러한 결과는 산삼 배양액의 급여에 의해 육제품에서 미생물의 번식을 억제하고 보존이나 내구성을 강화시키거나, 육계의 골격 형성과 육질 내 삼투압이나 항상성 유지에 도움을 줄 것으로 사료된다.

Proteomics is a useful approach to know protein expression, post-translational modification and protein function. We investigated the protein expression pattern and identity in chickens fed with the tissue culture medium waste after harvest of Korean wild ginseng (TCM-KWG) (Panax ginseng). Two groups (n=60/group) of day old broiler chickens were administered with 0 (control) and 0.8% (treatment) TCM-KWG through drinking water. After 5 weeks, we examined the protein expression pattern of fibularis longus and superficial pectoral muscle by Two-dimensional electrophoresis analysis. Interestingly, TCM-KWG treatment significantly increased five spot's density, and markedly reduced five spot's density in the muscles. We identified 10 proteins (desmin, myosin light chain 1, heat shock 25 kDa protein, collapsin response mediator protein-2A, alpha enolase, vimentin, actin alpha 1, my023 protein, pyruvate kinase and troponin T) by the matrix-assisted laser desorption ionization time of flight (MALDI-TOF).
