Micro-ecological leavening agent for feeding piglets, preparation method of leavening agent and active solid-state fermented feed

Abstract

The invention discloses a micro-ecological leavening agent for feeding piglets, a preparation method of the leavening agent and an active solid-state fermented feed. By screening and combining a plurality of strains, the micro-ecological leavening agent is prepared from the following raw materials in parts by weight: 1-3 parts of aspergillus awamori, 1-3 parts of aspergillus niger, 2-4 parts of candida tropicalis, 2-4 parts of geotrichum candidum, 1-3 parts of saccharomyces cerevisiae, 2-4 parts of aspergillus usamii and 2-4 parts of aspergillus oryzae. The micro-ecological leavening agent disclosed by the invention can be used for solving the problems of an existing microorganism fermented preparation which is too simple, incomplete in fermentation and poor in fermentation effect, the micro-ecological leavening agent is capable of achieving purposes of improving product quality and lowering product cost, and the micro-ecological leavening agent is effective on improving the nutrition titer and the utilization rate of nutrient feed. The feed disclosed by the invention, when applied to feed the piglets, has the characteristics of promoting growth and taking a significant effect on enhancing disease resistance, improving feed utilization efficiency, relieving pollution of a breeding environment and the like; and the piglets, applied with the feed, are free from residue of such drugs as antibiotics, hormone and the like, and the piglets are rich in nutrition and pure and natural in taste.

Description

technical field [0001] The invention relates to a micro-ecological starter for piglet feeding, a preparation method thereof and an active solid-state fermented feed, belonging to the technical field of feed microorganisms. Background technique [0002] China is one of the largest breeding countries in the world, and the demand for feed ingredients is increasing day by day. In recent years, with the in-depth study of animal nutrition, people have higher and higher requirements for feed, and people pay more attention to quality rather than just the pursuit of output. However, resources are gradually scarce, especially the shortage of protein sources, and the contradiction between supply and demand of protein is becoming increasingly acute. Among them, microbial fermented feed has been paid more and more attention. [0003] Microbial fermented feed refers to decomposing and synthesizing the anti-nutritional factors in plant, animal and mineral substances through the metabolis...
