Preparation technology of straw feed based on thread rolling and fermentation device treatment

Abstract

The present invention discloses a preparation technology of a straw feed based on a thread rolling and fermentation device treatment. The straw feed is prepared by a straw physical and biological fermentation treatment and a one-step aerobic fermentation and a one-step anaerobic fermentation. The steps are as follows: a thread rolling machine is used to conduct crushing and thread rolling of the straws; the straw threads are added into a fermentation machine to conduct a high temperature treatment to kill pathogenic microorganisms in the straw threads; compound microorganism strains and a nutrient solution are prepared; the straw threads in the fermentation machine are subjected to a temperature lowering treatment, and the compound microorganism strains are inoculated; the straw threads in the fermentation machine are subjected to the aerobic fermentation; the aerobic fermentation products of the straw threads are taken out to be weighed and the weighed aerobic fermentation products of the straw threads are filled into a fermentation bag for the anaerobic fermentation; and the finished products of the straw feed are obtained. By the threading of the straws, the fermentation and use of the straws are more effective and applicable, which improves the safety, palatability and nutrition of the straw feed, and enhances the health-care functions and growth promoting effects of the feed. The technology is suitable for breeding herbivores, especially breeding cattle, sheep, geese and other livestock.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and straw comprehensive utilization, in particular to a preparation process of straw biological feed. Background technique [0002] my country's straw resources are characterized by many types and large quantities. The total amount of straw produced by agricultural production activities is nearly 900 million tons every year. Due to the transfer of rural labor forces and the transformation of farming methods, the comprehensive utilization rate of straw is low, and most of the straw is burned or littered on the spot. The resulting agricultural non-point source pollution and environmental pollution have been increasingly affected. The government has successively issued a number of policies and accountability mechanisms to prohibit straw burning, and strongly supports the promotion of comprehensive utilization technologies such as straw feed. [0003] With the development of social ...

The abuse of feed additives and antibiotics not only reduces the meat quality of livestock and poultry, but even endangers the physical and mental health of human beings. It can also cause additives such as antibiotics and heavy metals in livestock and poultry manure to remain, and cause non-point source pollution and the discharge of livestock and poultry manure to cause eutrophication in water bodies. environmental issues such as
