Compound feed used in process of ecological cultivation of Guangxi partridge chicken under forest

The invention discloses a compound feed used in a process of ecological cultivation of Guangxi partridge chicken under forest. The compound feed comprises the raw materials: a powder material with a particle size of 0.2-0.4 mm and a particle material with a particle size of 2-3 mm; the density of the particle material is 1.15-1.3 g/m , and the weight ratio of the powder material to the particlematerial is 100:(1-3). The particle material is prepared by the following process: sterilizing coal gangue at high temperature, cooling, then adding peanut meal, coconut shell and pomegranate bark, crushing, mixing and granulating to obtain a prefabricated material; feeding cattle with the prefabricated material, digesting the prefabricated material by the cattle to form feces, and discharging thefeces; carrying out steam treatment on the cattle feces, drying, crushing, granulating, cooling to room temperature and drying to obtain the particle material. Additives such as antibiotics do not need to be added, the immunity
