A kind of preparation method of high-energy and high-protein feed

Abstract

The invention discloses a method for making a high-protein feed from raw materials of molasses, cassava residues and the like. The method comprises the following steps of performing heating, concentration and dehydration on molasses until a certain Brix is obtained; adding a certain quantity of cassava residues, and performing sufficient stirring; adding urea and mixed microbial strains; performing sealed fermentation for a certain time; then performing baking treatment; and finally adding a certain quantity of mineral substances and vitamins, and performing uniform mixing so as to obtain the high-energy high-protein feed. According to the method disclosed by the invention, saccharide in the molasses and the cassava residues is fully utilized, the urea is combined, and a reasonable carbon to nitrogen ratio is regulated; and through the effects of the microbial strains, non-protein nitrogen is converted into genuine protein, so that the absorptivity of animals is improved, and the prepared feed has the characteristics of being easy to digest, high in energy content, high in genuine protein content and the like.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a method for preparing high-energy and high-protein feed. Background technique [0002] Molasses is an important by-product of sugarcane sugar factory. It uses sugarcane as raw material, after pressing, cane juice is clarified, purified, filtered, evaporated, concentrated, crystallized, and then separated into a brown viscous liquid. Its output is the raw material 2.5-3% of sugarcane. The main feature of sugarcane molasses is its high sugar content, generally between 36% and 60%. The high sugar content determines that it is a fast-fermenting energy feed that can be fermented rapidly in the rumen and is easily used by microorganisms to stimulate The expansion and increase of the microbial flora enhances the digestive capacity of the rumen. In addition, its sweetness can mask the bad smell in the feed, thereby improving the palatability of the feed. Therefore, the use of molasses...

Problems solved by technology

[0004] Based on the above technical problems in the prior art, the present invention provides a method for making high-energy and high-protein feed using molasses and cassava dregs as raw materials, and solid molasses made by heating and dehydrating molasses, which solves the problems of difficult transportation and storage of molasses , add minerals to solve the imbalance of molasses mineral ratio, and add cassava dregs under high temperature molasses, so that the starch in cassava dregs gelatinizes at high temperature to form high-viscosity starch, which is adsorbed on the surface of urea solid particles together with molasses to form Strong chemical bonds enhance the binding force between particles, which is more conducive to the attachment of microorganisms to the carrier, improving the fermentation effect and shortening the fermentation time
