Abstract

This study was conducted to determine effects of different supplementation periods (2, 3 and 4 months) of spent composts of Se-enriched mushrooms (Se-SMC) on plasma glutathione peroxidase (GSH-Px) activity and selenium deposition of finishing Hanwoo steers for the optimal supplementing period determination in order to produce Se-fortified Hanwoo beef. In the present study, 30 Hanwoo steers were allotted to treatments in six groups of five steers per pen. Treatments were separated into control and Se-SMC for each supplementation period. Dietary selenium contents were 0.1 and 0.9 ppm for control and Se-SMC treatments, respectively. At the end of each supplementation period, steers by periods were slaughtered to collect hind leg and liver samples for their selenium analyses. Blood samples were taken to analyze whole blood Se concentration and plasma GSH-Px activity at the last day of each supplementation period. Dry matter intakes were unaffected by Se-SMC and supplementation periods. In addition, average daily gain was not different between control and Se-SMC treatments and among supplementation periods. There was no difference for total body weight gain between control and Se-SMC treatments within each supplementation period. The supplementation of Se-SMC significantly (P<0.001) increased whole blood Se concentration, but whole blood selenium concentration was not affected by the supplementation period. Furthermore, plasma GSH-Px activity showed similar trend as shown in the pattern of whole blood Se concentration, but no difference by supplementation periods was observed. Selenium contents in hind legs significantly (P<0.05) increased with increasing supplementation periods, and also they were significantly (P<0.001) higher for Se-SMC supplementation groups in comparison to controls. However, there was no difference for selenium contents of hind legs between three and four months supplementation. Selenium contents in livers tended to slightly increase with increasing supplementation periods with no significant difference, but they were significantly (P<0.01) higher for Se-SMC supplementation groups compared with controls within the same period. The results indicated that the optimal Se-SMC supplementation period for the selenium deposition in Hanwoo steers might be around two or three months when we considered selenium contents in hind legs and livers.

본 연구는 셀레늄강화 한우고기 생산을 위하여 셀레늄강화 버섯폐배지(Se-SMC)가 함유된 셀레늄사료(사료내 셀레늄함량: 0.9ppm)를 활용하여 급여사양기간(2개월, 3개월, 4개월)을 달리 하였을 때, 비육후기 거세한우의 조직 내 셀레늄 함량과 혈중 글루타치온 과산화효소(GSH-Px) 활성에 미치는 영향을 조사하여 최대 포화축적기간을 제시하고자 실시하였다. 본 연구에 사용된 비육후기 거세한우는 30두로 각 급여기간(2개월: 평균 체중 677kg, 3개월: 평균 체중 610kg 및 4개월: 평균 체중 524kg)에 대한 대조구 및 Se-SMC 급여구로 나누어 처리구당 5두씩 배치하여 총 6처리구로 구분하여 실시하였다. 대조구와 Se-SMC 급여구에 사용된 실험사료는 0.1과 0.9ppm의 셀레늄을 각각 함유하였다. 각 급여기간이 종료되면 도축하여 후지와 간을 채취하였으며 이를 셀레늄 함량분석에 이용하였다. 그리고 혈중 셀레늄 농도 및 글루타치온 과산화효소활성을 분석하기 위하여 도축 시에 채혈을 실시하였다. 건물섭취량은 Se-SMC 급여 및 급여기간에 의하여 유의한 차이가 나타나지 않았다. 또한 일당증체량은 대조구 및 Se-SMC 급여구간 그리고 급여기간 간에 유의한 차이가 나타나지 않았을 뿐만 아니라 총증체량 또한 각 급여기간내 대조구와 Se-SMC 급여구 간에 유의한 차이가 나타나지 않았다. Se-SMC 급여는 혈중 셀레늄농도를 유의하게 증가시켰으나(P<0.001), 급여기간에 따른 혈중셀레늄 농도에는 유의한 영향을 미치지 않았다. 아울러 혈중 GSH-Px 활성은 혈중 셀레늄농도에서 나타난 양상과 유사한 경향을 나타내었고, 급여기간에 의한 효과는 나타나지 않았다. 후지내 셀레늄 함량은 급여기간(P<0.05)이 증가함에 따라, 그리고 Se-SMC 급여(P<0.001)에 의하여 유의하게 증가하였다. 하지만, Se-SMC의 3개월 급여군과 4개월 급여군 간에는 유의한 차이가 나타나지 않았다. 간내 셀레늄 함량은 Se-SMC의 급여기간이 증가함에 따라 다소 증가하는 경향을 나타내었으나 유의한 효과는 나타나지 않았다. 하지만, 동일한 급여기간 내 Se-SMC는 대조구에 비하여 유의하게 높았다(P<0.01).이상의 결과로부터 근육내 셀레늄 축적을 위한 적정 Se-SMC 급여기간은 후지와 간내 셀레늄 함량을 고려할 때 약 2 내지 3개월의 급여가 충분할 것으로 사료된다.
