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 specifically relates to a method for preparing a high-energy and high-protein feed. Background technique

[0002] Molasses is an important by-product of sugar cane sugar mills. It is a brown viscous liquid produced by squeezing sugarcane, clarified, purified, filtered, evaporated, concentrated, crystallized, and separated from sugarcane. Its output is the raw material 2.5 to 3% of sugar cane. 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-fermented energy feed, which can be fermented quickly in the rumen, and is easily utilized by microorganisms. The expansion and increase in the number of microbial flora enhance the digestive capacity of the rumen. In addition, its sweetness can mask the bad odor in the feed, thereby improving the palatability of the feed. Therefore, the use of molasses in aquaculture prod...
