Method for preparing expanded premixed pig feed based on inferior fruits and vegetables and crop straws

Abstract

The invention provides a method for preparing expanded premixed pig feed based on inferior fruits and vegetables and crop straws. By steps of pre-fabricating inferior fruits and vegetables and crop straws: removing iron and removing impurities, drying, mixing and pulverizing, adding nutrients, performing extrusion-expansion, granulating and cooling, spraying compound probiotic powder, sieving, dehumidifying and packaging, the premixed pig feed granule finished product of extruded straw, fruit and vegetable is obtained. According to the method, the extruded straws are used as a carrier of the premix, the extruded inferior fruits and vegetables are used as active ingredients such as trace mineral elements and vitamins; the ecological cycle of straws, the inferior fruits and vegetables, and feeding is established; the comprehensive utilization of rural waste of extruded premixed pig feed produced from the inferior and discarded fruits and vegetables and the crop straws; raw materials areeasily available; minimization of added chemical additives is realized; safety and easy absorption are ealized; the material utilization is high; balanced nutrition is realized; the pollution is reduced; the palatability is good; additional economic value is added to waste resources.

Description

technical field [0001] The invention belongs to the technical field of processing methods for premixed pig feed, and in particular relates to a method for preparing puffed premixed pig feed based on defective fruits and vegetables and crop stalks. Background technique [0002] Pig feed is divided into complete feed, concentrated feed and premixed feed by category. Among them, premix is ​​the abbreviation of additive premix feed, which is the combination of one or more trace components (including various trace mineral elements, various vitamins, synthetic amino acids, certain drugs and other additives) and diluent or carrier according to the requirements. It is an intermediate compound feed product made after uniform mixing. Under the existing technology, most of the premixed pig feeds are made of chemical additives; the cost of chemical additives is high; raw materials are not easy to obtain; the effective absorption rate is not as expected. In this regard, under the exist...
