Method of producing bio-fermentation feedstuff by using the waste stalk dregs generated in the preparation course of ethanol by sorgo stalk

Abstract

The present invention relates to a method for producing biologically fermented feed with the waste stalk dregs left after the sweet sorghum stalk is used for preparing ethanol as the raw material; the method belongs to the technical field of feed processing. The waste stalk dregs after the sweet sorghum stalk is used for preparing ethanol are matched with oilseed residue and cottonseed residue to be the backing material. The cultured bacteria are inoculated on the smashed raw material and mixed evenly with the backing material; and then the mixture is packed in a plastic bag for solid fermentation; the raw materials in the plastic bag are compressed tightly and compacted; the bag is sealed to form an anaerobic environment for controlling the growing of bacteria and fermenting for 15 to 20 days within the temperature range of 20 to 38 Celsius degrees. The present invention produces full-price feed which is rich in nutrition and at the same time the present invention can solve the problem of environmental pollution caused by ethanol industry. Nutrition is richer after the waste stalk dregs of sweet sorghum is mixed for use with a plurality of other raw materials such as oilseed residue and cottonseed residue and the crude protein content is obviously increased. As for feeding, the fermented feed can replace 20 percent of the basal ration; the rate of gain and slaughter rate are obviously increased and the feed cost can be saved by about 10 percent.

Description

technical field [0001] The invention relates to a method for producing biologically fermented feed by using waste stalk residue produced by ethanol production from sweet sorghum stalks as raw materials, and belongs to the technical field of feed processing. Background technique [0002] The invention aims at the problems existing in the ethanol production industry using sweet sorghum stalks as raw materials, and proposes a new technical proposal for the feed treatment of waste stalk residue. Sweet sorghum is an energy crop, and sweet sorghum stalk is an important raw material for the ethanol industry. In the process of producing ethanol, a large amount of waste sweet sorghum stalks will be produced. Sweet sorghum waste stalks contain certain nutrients and can be directly used as feed. However, because the palatability and nutritional content of these waste stalks do not meet the requirements of the animal husbandry industry, and the backlog of waste stalks will cause envir...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the environmental pollution caused by the waste stalk residue produced by ethanol production from sweet sorghum stalks, as well as the disadvantages of low nutritional content and poor palatability of the waste stalk residue, and provide a method that can make full use of sweet sorghum stalks as raw materials. The ethanol industry waste stalks can improve the nutritional value of sweet sorghum waste stalks, making it a high-quality feed widely used in animal husbandry
