Abstract

This experiment was carried out to study the effect of dietary Monascus culture on the cholesterol contents of egg yolk, muscle and serum of layers with 180 Isa-Brown laying hens for 10 weeks. Control group(C) was fed the commercial laying hen diet and 2.67(T1), 5.33(T2) and 8.00(T3)% of Monascus culture which contained 0.6% monacolin-k added to control diet so as to supply the monacolin-k 20(T1), 40(T2) and 60(T3) mg respectively, per hen-day with 125g diet. Hen-day egg production and average egg weight were not affected by the dietary Monascus culture, but feed intake and feed conversion per kg egg were significantly decreased(P<0.05) as the dietary Monascus culture increased. Cholesterol contents of egg yolk measured 4~5 weeks after feeding the Monascus culture and those of thigh meat measured at the end of experiment were significantly decreased(P<0.05) as the dietary Monascus culture increased. Average cholesterol contents of serum showed a trend to decrease as the dietary Monascus culture increased without significant difference.

Monacolin-K가 0.6% 들어있는 Monascus 배양물을 시판 산란계 시료에 각각 0.00%, 2.67%, 5.33% 및 8.00%씩 추가로 첨가하여, 1일 1사당 사료섭취량이 125g일 경우 1일1수당 Monacolin-K 섭취량이 각각 0, 20, 40 및 60mg이 되도록 하는 4개 처리를 두었고, 총 180수의 산란계를 공시하여 10주간 사양시험을 실시한 결과 산란율과 평균 난중은 처리간에 유의적인 차이가 없었으나, 사료섭취량과 산란량 kg당 사료 요구율은 Monascus 배양물의 첨가수준이 증가할수록 감소하였다. 전 기간 평균 혈청 콜레스테롤 함량은 Monascus 배양물의 첨가수준이 증가할수록 감소하는 경향이었으나, 유의적인 차이는 없었다. 난황의 콜레스테롤 함량은 Monascus 배양물 첨가급여 4~5주 후부터 유의적으로 감소하였고(P<0.05), 사양시험 종료시 대퇴부근육의 콜레스테롤 함량도 유의적으로 감소하였다(P<0.05).
