        서성(Sung Seo),한대덕(Dae Duk Han),장선식(Sun Sik Jang),김원호(Won Ho Kim),정민웅(Min Woong Jung),최진혁(Jin Hyuck Choi),김진숙(Jin Sook Kim),김하영(Ha Young Kim),이종경(Joung Kyong Lee) 한국초지조사료학회 2012 한국초지조사료학회지 Vol.32 No.1

        본 연구는 부존 조사료자원 이용으로 수입사료를 줄이고 사료비를 절감하고자 2010년도에 전남 해남(간척지), 강원 평창(강변), 원주(섬강변), 전남 영광(와탄강변) 등 4개 지역에서 갈대와 억새 등 야초 자생지를 탐색하고, 수확·이용실태 조사와 함께 사료가치를 분석하였다. 전남 해남 해남목장 내 갈대(Phragmites communis) 위주의 야초 자생지는 300 ha로 예년에는 2회 곤포작업하여 연간 사일리지로 2,300~2,500톤(ha당 8톤)을 생산하였으나 2010년도는 1회 곤포조제로 사일리지 2,000톤(ha당 7톤)을 생산하였다. 유통가격은 롤 당 53천원으로 ㎏당 110원이었다. 곤포는 전량 자가소비하며, 외부 작업단에 롤 당 26천원의 작업비를 지불하였다. 연간 조수입은 2억 2,260만원이며, 소득은 1억원 수준(345천원/ha)이었다. 초장 150 ㎝의 갈대는 조단백질 8.4%, 상대사료가치 71.9 (건초 5등급), 건물 소화율 60.1%로 사료가치는 볏짚에 비해 약간 나은 것으로 평가되었다. 갈대 사일리지의 사료가치와 유기산 함량은 동일 지역에서 동일한 재료로 사일리지를 조제하더라도 수확시기에 따라 차이가 컸으며(CP 4.7~6.4%, RFV 62.2~78.9, 건물 소화율 41.9~53.9%), 갈대 사일리지의 품질은 수단그라스에 비해 불량하였다. 강원 평창 강변 자생갈대의 사료가치는 초장이 79, 117, 121, 142㎝로 생육이 진행됨에 따라 낮아져, 조단백질은 각각 13.9%에서 7.6%로, 상대사료가치는 90.7 (건초 3등급)에서 76.1 (건초 4등급)로, 건물 소화율은 72.9%에서 54.7%로 감소하였다. 원주 섬강 주변 야초류는 곤포수확 작업에 어려움이 있었으며, 초장 130 cm의 갈대는 조단백질 8.5%, 상대사료가치 82.3 (건초 4등급), 건물 소화율 70.2%로 사료가치는 높았으며, 220㎝의 성숙한 갈대는 조단백질 10.2%, 상대사료가치 65.1 (건초 5등급), 건물 소화율 48.9%로 볏짚 대비 조금 나은 것으로 평가되었다. 전남영광지역에서는 와탄천 주변에 자생하는 갈대를 수거 이용하고자 시도하였으나 경제성이 없어 중단하였다. 이상의 결과를 종합하여볼 때, 갈대, 억새 등 야초류는 현 상태에서 최대한 수거·이용하되, 사료가치를 유지하고 가축 기호성이 양호한 시기에 수확하는 것이 중요하며, 최소한 볏짚과 비슷하거나 그 이상의 사료가치를 기대하기 위해서는 7월 중순 이전(늦어도 7월까지)에 수확·이용하는 것이 권장된다. This study was carried out in 2010 to investigate the utilization and forage quality of native grasses, such as Phragmites communis which might reduce the cost of feeding domestic cattle. The regions surveyed were the Haenam ranch in Haenam, Pyeongchang, Wonju, and Yeonggwang. In Haenam, yearly silage production harvested from 300 ha was 2,000 MT (7 MT/ha). All of those round bale silages were self-consumed in that region, and marketing price was 50,000 55,000 won per roll (110 won/㎏). Phragmites communis of 150 ㎝ in length contained 8.4% crude protein (CP) with relative feed value (RFV) 71.9 and 60.1% in vitro dry matter digestibility (IVDMD), which was somewhat more favorable than forage quality of rice straw. The silage quality of Phragmites communis varied greatly by the time of harvest (CP 4.7 6.4%, RFV 62.2 78.9, and IVDMD 41.9 53.9%), even with the same district and of the same original forage materials. Generally, the quality of Phragmites communis silage of was poorer than that of sorghum * sudangrass hybrid. In Pyeongchang, forage quality of Phragmites communis was decreased from 13.9% to 7.6% in CP, 90.7 to 76.1 in RFV, and 72.9% to 54.7% in IVDMD, as plant was getting mature, from 79 ㎝ to 117 ㎝, 121 ㎝ or to 142 ㎝ in length. In Wonju, the quality values of Phragmites communis of 130 ㎝ in length were 8.5% CP, 82.3 RFV and 70.2% IVDMD, while those of matured grasses of 220 ㎝ in length were lower (10.2% CP, 65.1 RFV and 48.9% IVDMD), but this was a little more favorable than quality of rice straw. In Yeonggwang, feeding Phragmites communis was tried in a Hanwoo feed, but stopped due to low profitability. In conclusion, the overall quality of most native grasses including Phragmites communis in this survey was poor. Therefore, we recommend that Phragmites communis and native grasses should be harvested on June or July to obtain richer forage quality in forage values than rice straw.

        2010 파주, 안산지역 갈대, 억새 등 야초류의 이용실태와 사료가치 평가

        서성(Sung Seo),김원호(Won Ho Kim),정민웅(Min Woong Jung),박형수(Hyung Soo Park),심재진(Jae Jin Shim),박진길(Jin Gil Park),성하균(Ha Guyn Sung),김종덕(Jong Duk Kim),이종경(Joung Kyong Lee) 한국초지조사료학회 2011 한국초지조사료학회지 Vol.31 No.2

        본 연구는 부존 조사료자원의 이용을 활성화하여 수입사료를 줄이고 가축 사료비를 절감하고자 2010년도에 경기 파주 (민통선 지역)와 경기 안산 (시화지구)에서 갈대와 억새 등 야초자생지를 탐색하고, 수확?이용실태 조사와 함께 사료가치를 분석하였다. 파주 민통선 내억새 (Miscanthus sinensis)와 갈대 (Phragmites communis) 혼합 자생지는 90~100 ㏊ 규모로, 1차 곤포작업으로 사일리지 520톤 (㏊당 6톤), 2차로 380톤 (㏊당 4톤)을 조제하여, 연 사일리지 900톤 (㏊당 10톤)을 생산하였다. 곤포의 유통가격은 롤당 52~55천 원으로 ㎏당 130~137.5원이었다. 곤포는 자가소비 50~70%, 판매유통 30~50%로, 수익성은 인건비 정도로 추정되었다. 초장 70 ㎝의 재생 억새는 조단백질 9.6%, 상대사료가치 82.4 (건초 4등급), 건물 소화율 67.7%, 초장 70 ㎝의 재생 갈대는 각각 13.8%, 84.3 (4등급), 67.9%로 사료가치는 높았으며, 수확이 늦어짐에 따라 사료가치는 크게 낮아졌다. 안산 시화지구 (3공구)의 갈대 등 야초류자생지는 100 ㏊ 정도로 2009년도에는 50 ㏊에서 사일리지 550톤 (㏊당 11톤)을 생산하여 롤당 50천 원에 유통하였으며, 2010년도는 잦은 강우와 장마로 부분 이용에 그쳤다. 고초기의 갈대는 건물률 89.8%, 조단백질 2.2%, NDF 80.6%, ADF 55.4%, 상대사료가치 52.9 (5등급), 건물 소화율 36.4%로 볏짚에 비해서도 사료가치는 크게 낮았다. 초장 80 ㎝의 재생 갈대는 조단백질 12.9%, 상대사료가치 99.8 (3등급), 건물 소화율 66.6%로 사료가치는 양호하였으며, 개화기의 초장 150 ㎝ 갈대는 조단백질 4.5%, 상대사료가치 59.9 (5등급), 건물 소화율 42.2%로 볏짚의 사료가치와 비슷하였다. 이상의 결과를 종합하여볼 때, 갈대, 억새 등 야초류는 현 상태에서 최대한 수거?이용하되, 사료가치를 유지하고 가축 기호성을 고려한 시기에 수확하는 것이 중요하며, 최소한 볏짚과 비슷하거나 그 이상의 사료가치를 기대하기 위해서는 7월 중순 이전 (늦어도 7월까지)에 수확?이용하는 것이 권장된다. 본 연구에서 조사된 대부분의 야초류는 상대사료가치가 75 이하인 건초 5등급으로 사료가치는 매우 낮았으며, 키가 작은 영양생장기에 수확한 경우에만 4등급으로 나타났다. 부존 조사료자원의 이용은 양질의 사료작물 생산과 병행하여 추진하는 것이 바람직하였다. This study was carried out in 2010 to investigate the utilization and nutritive value of native grasses, such as Phragmites communis and Miscanthus sinensis which might reduce the cost of feeding domestic cattle. The regions within the Civilian Control Line in Paju and Sihwa region in Ansan were surveyed. In Paju, the yearly silage production was 900 MT harvested from 90 ha (10 MT/㏊). About 30~50% of these were sold out at the marketing price of 52,000~55,000 Won per roll (130~137.5 Won/㎏). Regrown Miscanthus sinensis of 70 ㎝ in length contained 9.6% of crude protein (CP), 82.4 of relative feed value (RFV), and 67.7% of in vitro dry matter digestibility (IVDMD). Regrown Phragmites communis of 70 ㎝ in length contained 13.8% of CP, 84.3 of RFV, and 67.9% of IVDMD. As harvesting was delayed, the quality was decreased dramatically. In Ansan region, Phragmites communis plantation covers 100 ha. The silage production was 550 MT from the area of 50 ha (11 MT/㏊) in 2009. And the marketing price was 50,000 Won per roll. But in 2010 only a small amount of grasses could have been baled due to frequent and much rainfall from spring to summer season. However, the good forage quality was observed from regrown Phragmites communis of 80 ㎝ in length, 12.9% CP, 99.8 RFV and 66.6% IVDMD, while that of late matured grasses was very low, 2.2% CP, 52.9 RFV and 36.4% IVDMD, greatly lower than forage quality of rice straw. The quality of grasses at bloom stage of 150 ㎝ in length was similar to that of rice straw, showing 4.5% CP, 59.9 RFV and 42.2% IVDMD. In conclusion, the overall quality of most native grasses in this survey were very poor. Therefore, we recommend that Phragmites communis and Miscanthus sinensis should be harvested during June or July to obtain better forage quality which is richer in forage values than rice straw. Production of high quality forage crops was also desirable for self sufficiency of forage.

        Background : This study was carried out in order to investigate the discrepancy between the histology obtained through the preoperative endoscopic biopsy and post operative resection. Methods :To analyse the factors affecting the discrepancy 280 cases, in 270 gastric adenocarcinoma patients who underwent surgical operation in this hospital since 1st August, 2004, to 31st July 2005, were subjected to present study. Histologic types were categorized into well-differentiated tubular(WD-T), moderately-differentiated tubular(MD-T), poor-differentiated tubular(PD-T), signet ring cell carcinoma, and papillary adenocarcinoma(Pap). The data is gender, tumor marker, concordance of pathologist, tumor location, T and N factor, and stage in this study Results : From the cases exhibiting WD-T, MD-T, PD-T, and SRC in endoscopic biopsy,52.9%, 60.4%,38.9% and 65.6%, respectively, showed the same pathology in resected specimen. The sensitivity was analysed as 70.3%, 52.9%, 26.9%, 80% respectively. For the statistically significant factors affecting the pathologic discrepancy, male patient showed higher discrepancy. In this cases, the discrepancy rate of gender is 49% in male, 34% in female patients with elevated CEA level had higher discrepancy. And that is statistically significant factors affecting the pathologic discrepancy. However, Patients with elevated CA19-9 levels also showed higher discrepancy, but no significance. Also, There is no difference about discrepancy according to concordance of pathologists who reported histologic biopsy, in the preoperation and postoperation. When discrepancy was presented, 44.9% was reported in accord case, 44.2% was reported in discord case with respect to pathologist. As for the discrepancy following the location of tu or, data showed less discrepancy, in cases where tumor was located at the lower 1/3, but this showed no significance. In the change of pathologic results based on T,N factor, It showed no significance.but, it is noticeable in mucosal, submucosal cancer that was reported 32.2% and 57.4% present rate of discrepancy, patients with elevated stage had higher discrepancy, but this showed no significance. Conclusions : The statistically significantly factors that affected the pathologic discrepancy were gender, and rise in CEA level. Mucosal and submucosal cancer showed discrepancy in 32.5% and 57.4% respectively, and further study is thought to be necessary. Also, further retrospective study with more cases is thought be needed for early gastric adenocarcinoma
