Abstract

Effects of fermented food waste feeds on meat quality and physico-chemical characteristics of fully grown pigs were investigated. Two treatments were tried in this study; commercial feed (control) and fermented food waste feed(FFWF). Except for much thicker backfat of control, carcass traits, carcass weight, dressing percentage, carcass grade, cooking loss, shear force, water-holding capacity, drip loss, NPPC meat color, and marbling score of commercial feed(control)- and fermented food waste feed (FFWF)-fed pigs were not significantly different. Primal cut weights and meat percentages were significantly different (p<0.05) between control and FFWF. pH of FFWF loin was significantly lower (p<0.05) than that of control. FFWF loin showed higher L*-value and lower a*-value compared to control.

본 실험은 돈육의 도체성적과 육질을 비교함으로써 남은 음식물 발효사료 급여효과를 살펴보고자 실시하였다. 도체성적으로 생체중, 도체중, 도체율, 등지방두께, 도체등급, 부분육량 및 정육율을 측정하였으며, 육질평가로 pH, 보수력, 저장감량, 가열감량, 전단력, 육색 및 NPPC 육색 및 근내지방도를 측정하였다. 도체특성에 있어서 등지방두께를 제외하고 도체중, 지육율 및 최종등급은 대조구와 FFWF구간에 유의적인 차이가 없었으며, 부분육 생산량과 정육율에 있어서는 FFWF구가 대조구에 비하여 다소 높게 나타났다. 육질특성에 있어서는 pH는 FFWF구가 대조구에 비하여 다소 낮게 나타났으나, 보수력, 드립감량, 가열감량, 전단력 등은 대조구와 FFWF구간에 유의적인 차이가 없었다. 육색에 있어서는 FFWF구가 대조구에 비하여 L*-값이 높고 a*-값이 다소 낮게 나타났으며, 주관적인 방법으로 측정된 NPPC 육색과 근내지방도는 처리구간에 차이가 없었다 따라서 본 연구의 결과로 볼 때 남은 음식물 발효사료의 급여가 일반배합사료 급여와 비교하여 도체 및 육질 특성에 있어서 크게 떨어지지 않는 것으로 판단되었다.
