The invention discloses feed for quails in an egg producing period and a manufacturing device, and relates to the technical field of animal feed. The feed for the quails in the egg producing period is prepared from the following formula raw materials of cassava slices, mycoprotein, cassava residues, stone powder, tallow, red rice koji residues, polymerase peptides, calcium hydrogen phosphate, table salt, lysine, methionine, arginine, threonine, choline chloride, a quail premix, isoleucine, valine, tryptophan and yellow mealworm excrement. According to the feed for the quails in the egg producing period, feed waste residues are adopted for replacing corn and soybean meal raw materials for preparation, dependence on the corn and soybean meal raw materials is relieved, resource utilization is improved, and contribution is made for relieving feed resource insufficiency and reducing livestock and poultry feeding cost; the manufacturing device can accurately control the temperature in a box body during fermentation; compared with fermentation depending on the external natural temperature, the application range is wider; compared with the situation that a cover needs to be used for sealed fermentation in a fermentation cylinder, operation is easy, and the practicability of the device is effectively improved.
