Abstract
This experiment was conducted to investigate the effects of feeding with MS (miraculous soil-bacteria)-fermented food waste on feeding efficiency and meat quality of mallard. Twenty one heads of 12 weeks-old mallards were fed with three different mixing rates of MS-fermented food waste (0, 20 and 50 %) with 7 replicates. After 6 weeks of feeding, weight gain and feed intake were measured to estimate feeding efficiency, moreover physico-chemical characteristics, amino acids and fatty acids of the fresh slaughtered mallards were analyzed to determine meat quality. The feeding efficiency of 0 % fermented food waste (control) was significantly (p<0.05) higher than other treatments. Water holding capacity and pH were not significantly differed. The color value in lightness of control meat was higher, while in redness was lower than that of the plots mixed with fermented food waste. Total content of amino acids in thigh meat was relatively lower in control, but that in breast meat showed a reverse trend. The amount of unsaturated fatty acids in both thigh and breast meat was the highest in the 50 % mixed plot. Considering economic and environmental aspects for mallard feeding, this results indicated that MS fermented food waste could be a useful resources for mallard feed.
본 연구는 대조구로서 일반배합사료에서 사육된 청둥오리와 처리구로서 일반배합사료에 MS 발효 잔반사료를 20% 또는 50%를 혼합하여 일정기간 사육한 후 사육효과를 알아보았고 이화학적 분석 및 아미노산과 지방산 분석 등을 통해 처리구에 따른 육질을 비교함으로서 MS 발효 잔반사료의 오리사료로서의 효율성을 검토하였다. 사육효과에 대한 결과로서 도체율 및 각 장기무게는 대조구와 처리구간에 유의적 차이가 발생되지 않았으나, 사료효율에 있어서는 처리구보다 대조구에서 좋은 결과를 보여주었다 (P<0.05). 이화학적 분석으로서 보수성과 pH는 모든 처리구간에 있어서 유의차가 없었다. 그러나 육색에 대한 결과를 보면 명도(
