The invention relates to meat duck feed and a processing method thereof. The feed comprises the following ingredients in percentage by weight: 42.83 percent of maize, 19 percent of wheat shorts, 13 percent of beam dregs, 8 percent of cotton dregs, 5 percent of rape seed cake, 3 percent of maize germ cake, 2.0 percent of maize protein powder, 0.8 percent of lard, 1.3 percent of mountain flour, 1.5 percent of calcium hydrophosphate, 1.5 percent of fish meal, 0.21 percent of common salt, 0.58 percent of lysine, 0.15 percent of methionine, 0.13 percent of threonine, 0.2 percent of composite bio-enzyme preparations and 1.0 percent of premix. The processing method comprises the following steps of: crushing and/or grinding all ingredients in the feed; then, adding various raw materials into a stirring machine to be stirred; and finally, packing the stirred feed into bags. The conversion rate, the quality stability and the dreg type protein consumption of the feed are improved through the use of additives, so the cost of the feed is reduced, and the growth expression of meat duck can be maintained or improved.
