초록

항암 효과, 노화 억제, 중풍 억제, 혈압과 콜레스테롤 저하효과 및 당뇨병 치료 효과 있다고 알려진 잠분(蠶糞)을 비육 돈에 급여하여 비육돈 체조직내에 생리활성 물질을 축적시키고, 생리 활성 물질이 축적된 돈육의 품질 특성에 대한 연구를 수행하였다. 잠분은 건조 상태(수분 $10\%$ 내외)의 잠분을 급여하였다. 대조구는 출하시까지(110 kg) 일반사료를 급여, 처리구 1, 2, 3,은 사료함량에 잠분을 각각 1, 2, $3\%$ 첨가하여 4주간 급여하였고, 처리구 4, 5, 6은 1, 2, $3\%$로 각각 첨가하되 8주간 급여하였다. 급여시험이 끝난 후 일괄적으로 도축하여 돈육의 등심 부위를 함기 포장하여 냉장온도$(4^{\circ}C)$에서 12일간 저장하면서 돈육의 품질 특성 변화에 대하여 조사하였다. pH는 대조구와 잠분 급여구 간에는 유의적인 차이가 없었으며, 저장 기간이 경과함에 따라 모든 처리구가 증가하는 경향을 보였다. 일반성분, 가열 감량 및 조직감은 대조구와 잠분 급여구 간에는 유의적인 차이가 없었다. 보수성은 대조구에 비하여 잠분 급여 처리구가다소 높은 결과를 보였으며, 저장기간이 경과할수록 전 처리구가 유의적으로 감소하는 결과를 보였다.(p<0.05). 육색과 지방색의 명도, 적색도 및 황색도는 대조구와 잠분 급여 처리구간에 유의적인 차이가 없었으며, 저장기간이 경과함에 따라 육색의 명도와 황색도는 약간 증가하였다. 대조구와 잠분 급여 처리구간의 비교에서 전 저장기간 동안 뚜렷한 차이가 없는 것으로 나타났으며, 저장기간이 경과할수록 모든 처리구들이 유의적으로 낮아지는 결과를 보였다(p<0.05). 이상의 결과를 종합해 보면 잠분을 돼지 사료에 첨가하여 급여하면 일반성분, 조직적 특성 및 이화학적 성질에 영향을 미치지 않고 고 기능성 돈육 생산이 가능하다고 사료된다.

This study investigated the effects of silkworm droppings (SWD) added diet feeding on quality characteristics of pork loin meat Pigs were divided into 7 treatment groups (10 pigs/group) and subjected to one of seven treatment diets $(0,\;1\%,\;2\%\;and\; 3\%\;SWD\;for\;4 weeks,\;1\%\;2\%\;3\%$ SWD for 8 weeks, SWD diets; total fed diets) before slaughter. Pork loin were collected from the animals (110kg body weight) slaughtered at a commercial slaughterhouse. Pork loin meat were packaged aerobically and then stored at $4^{\circ}C$ for 2, 5, 8, or 12 days. Samples were analyzed for general composition, texture characteristics and physico-chemical properties. pH value was not significantly different between the control and SWD treatment groups. pH of control and SWD treatment groups were increased as the storage period passed General composition, cooking loss and texture was not significantly different between the control and SWD treatment groups. WHC of SWD treatment group was higher than that of control group. WHC of control and SWD treatment groups were significantly decreased as the storage period passed (p<0.05). Meat and fat color (CIE $L^{\ast}$, $a^{\ast}$, $b^{\ast}$) were no significant differences between the control and SWD treatment groups. $L^{\ast}$ and $b^{\ast}$ value of meat color were decreased as the storage period passed There was a not significantly difference in shear force value among control and SWD treatment groups. Shear force value was decreased significantly during storage in all treatment groups. In all results, dietary SWD-supplementation was not affected in general components, texture characteristics and physico-chemical properties. It is suggested that dietary SWD-supplementation could produce of high quality pork.
