초록

본 연구는 공시균인 Aspergillus terreus와 유산균을 이용할 시에 성장률과 육질에 미치는 영향을 조사하고자 거세돈 60 두를 60일간 그리고 육계 120수를 6주간 사양하였다. 대조구는 일반 시판사료만 급여하였고, T1구는 Aspergillus terreus 배양체, T2구는 시판중인 EM-pro 배양체(Lactobacillus acidophilus, Bacillus subtilis, Saccharomyces cervisiae 3종 혼합배양물)를 각각 $0.2\%$씩 첨가 급여한 결과는 다음과 같다. 돼지의 일당 증체량과 총 증체량은 대조구가 높은 경향이었고, 사료요구율은 T2구가 다른 처리구보다 가장 높았다 (P<0.05). 그러나 육계의 일당 증체량과 총 증체량은 T1구와 T2구가 높은 경향이었고, 사료요구율은 T2구가 다른 처리구보다 가장 높아 통계적인 유의차가 있었다(p<0.05). 돼지고기의 조지방 함량은 대조구$(2.72\%)$가 T1구$(1.44\%)$와 T2구(1.59)보다 유의적으로 높았고(p<0.05), 닭고기는 T1구$(0.36\%)$가 가장 낮아 통계적인 차이가 있었다(p<0.05). 돼지고기의 pH, 가열감량, 보수성 및 전단력은 처리구간에 통계적인 차이가 없었으나(p>0.05), 닭고기에서 가열감량과 보수성은 대조구가 높았고, 전단력은 T1구와 T2구가 높았다(p>0.05). 돼지고기의 다즙성, 연도, 향미는 대조구(각 4.95, 4.85, 4.60)가 가장 높았고(p<0.05), Aspergillus terreus로 처리한 T1구(각 3.90, 3.80, 3.85)는 상대적으로 가장 낮았다(p<0.05). 돼지고기의 육색은 모든 처리구간에 차이가 없었고, 닭고기의 a와 b값은 대조구(7.99)가 다른 처리구보다 높았다(p<0.05). 따라서 Aspergillus terreus 첨가 급여는 축종에 따라 고기의 지방함량 및 육질에도 다소 영향을 미치는 것으로 판단된다.

This study was conducted to determine the effect of supplemented useful micro-organism on performance and meat quality of growing-finishing pigs for sixty days and broiler for six weeks. The pig and broiler were randomly allotted into 3 treatment; Control 0 (C), T1 (supplemented with $0.2\%$ Aspergillus terreus), T2 (supplemented with $0.2\%$ EM-pro). In total experimental period, feed conversion and dairy feed intake were tend to be higher in T2(2.09kg, 2.70kg) than others. But ADG (average daily gain) was tend to decreased n (0.78kg) according to supplemented of Aspergillus terreus diet These treatments were not significant difference. The chemical composition of pork were not significant difference except for crude fat Crude fat content was lower Aspergillus terreus treatments than others. The pH tenderness, WHC and heating loss were not significant difference in pork $(p>0.05)$. In chicken meat, heating loss and WHC of control was higher than that of T1 and n but shear value was higher in T1 and n. Values of juiciness, tenderness and flavor were improved with highly significant difference (p<0.05) in control (4.95, 4.85, 4.60) than T1 and n in pork. Although the meat color was not significant difference in pork but a and b values of control was higher than that of T1 and n in chicken meat (p<0.05).
