Abstract

본 시험은 국내 TMR 배합소에 대한 실태조사를 통하여 문제점을 파악하고 개선방향을 제시하기 위하여 수행하였다. TMR 배합소 20개소 조사결과 조사 배합소의 65%인 13개소가 사료배합비 작성을 외부에 의뢰하고 있는 것으로 조사되었으며, 배합비 작성 등 컨설턴트 비용으로 월 평균 <TEX>$50{\sim}90$</TEX>만원 정도를 지출하고 있어, 컨설팅 비용에 대한 부담으로 경영비를 상승시키는 요인이 되는 것으로 나타났다. 국내 유통 TMR에는 에너지가인 TDN가를 표기하고 있지 않아 농가에서 구입 활용 시 적정영양소 균형급여가 어려운 실정이다. 국내 유통 TMR에 대한 건식 TMR의 추정 TDN가는 개인공장 TMR 63.0, 생산자단체 TMR 73.2로 나타났으며, 습식 TMR의 추정 TDN가는 개인공장 TMR 64.9, 생산자단체 TMR 67.2로 생산자단체의 TMR이 개인공장의 TMR 보다 에너지가 높은 것으로 나타났다. TMR 배합소에서 생산되는 TMR 제품의 가격은 건물기준으로 비교해 보았을 때, kg당 건식 TMR은 <TEX>$325.6{\sim}347.0$</TEX>원이었으나 습식 TMR은 <TEX>$365.7{\sim}375.0$</TEX>원으로 습식 TMR의 가격이 높았다. TMR 배합소 종사자들의 TMR의 확대 보급을 위한 선결과제로는 TMR 교육 및 홍보와 TMR 배합비 작성능력 향상을 요구하였다. 따라서 국내 TMR 배합소의 발전을 위해서는 관련 종사자에 대한 전문적인 교육이 뒷받침 되어야 함을 알 수 있다. This experiment was carried out to show a reform measures by grouping for problems by the survey of TMR plants. Twenty total mixed ration (TMR) plants (10 cooperation and 10 private plants) were surveyed, of which 13 plants, 65% of total TMR plants, committed TMR formulae to a outside nutrition specialist (TMR formulator). With respect to consulting fee for TMR formulae, <TEX>$500{\sim}900$</TEX> thousands Won was paid monthly. On the basis of dry matter 1kg, the prices of TMR products were <TEX>$325.6{\sim}347.0$</TEX>Won, whereas those of wet TMR products <TEX>$365.7{\sim}375.0$</TEX>Won, which was appeared to be factors to increase management cost. And also, because the TMR plants did not provide TDN (total digestible nutrient) value on their products, nutritional balance feeding for cows could not be managed in farms. It was calculated, based on ADF (acid detergent fiber) value, that TDN value in dry type TMR was 63.0% and 73.2% fur private and cooperation TMR plants, respectively and that the corresponding figure in wet type TMR was 64.9% and 67.2%. According to TMR plant employee's opinion, a prier items to enlarge TMR utilization were TMR education, TMR advertisement, and improvement of ability to make TMR formula. Therefore, for the purpose of further development of TMR, special education of persons related to TMR should be supported.
