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.

This study was carried out to get the basic data on the efficient processing method of food wastes for utilizing as the resources of swine feeds composition, mineral and toxic elements of food waste were estimated in relation to the steps of processing and fermentation with MS (Miraculous soil-bacteria) microorganism complex. The chemical composition of food wastes was largely varied according to disposing sites, collection time and season. Offensive odor was reduced by anaerobic fermentation with MS microorganism complex. Food wastes fermented with MS microorganism complex have high contents in crude protein (24.1% D.M) and crude fat (12.9% D.M). Mineral composition was to be relatively well balanced compared to other plant or animal feed resources. Particularly the content of sodium was slightly higher than that of grains or agricultural byproducts. In food wastes fermented with MS microorganism complex, heavy metals such as Hg, As or F were not detected. Pb or Cd were detected in small quantities but their levels were below the dose s-permitted feeding standard of permitted dose in feeding standard. These results indicated that food wastes could be efficiently used for the resources of swine feeds through proper processing and fermentation.
