Powdery compound feed for Wuding chicken

The invention relates to powdery compound feed for Wuding chicken and belongs to the technical field of poultry feed. The powdery compound feed for the Wuding chicken is prepared from the following raw materials in weight percent: 50 percent to 56 percent of corns, 13 percent to 18 percent of soybean meal, 9 percent to 12 percent of corn protein powder, 13 percent to 15 percent of barley, 1 percent to 2 percent of calcium hydrogen phosphate, 1 percent to 2 percent of mountain flour, 0.2 percent to 0.3 percent of table salt and 1 percent to 2 percent of a compound premix; a granularity distribution range is that feed particles with the granularity smaller than 400 microns account for 28 percent to 30 percent, feed particles with the granularity greater than or equal to 400 microns and smaller than 1000 microns account for 55 percent to 58 percent, feed particles with the granularity greater than or equal to 1000 microns and smaller than 2000 microns account for 13 percent to 15 percent and feed particles with the granularity greater than 2000 microns account for less than 1 percent. According to the growth physiological characteristics of the Wuding chicken, the raw materials including the corns, the barley, the soybean meal and the like are matched, and formula trophism and formula cost are considered; the anti-trophism problem of non-starch polysaccharides in the feed is solved, and the powdery compound feed has no bad influences on the growth performance of the Wuding chicken; meanwhile, the particle granularity distribution range is provided, the feed utilization efficiency is improved and the culture benefits of the Wuding chicken are improved.
