Preparation method of rumen-derived microbial fermentation feed rich in volatile fatty acid calcium

Abstract

The invention relates to a preparation method of a rumen-derived microbial fermentation feed rich in volatile fatty acid calcium. The preparation method comprises the following steps of after collecting rumen liquor, performing direct culture or in vitro culture so as to prepare strain liquor; crushing fine and coarse feed products, performing pulping to obtain pulp, and pumping the pulp into a fermenter; after raising the temperature and introducing CO2 for deoxygenization, adding trace element nutrient buffering liquor and the strain liquor, strictly performing anaerobic fermentation to prepare fermentation liquor, then performing solid-liquid separation to obtain a solid wet base and liquid nutrient liquor; and directly concentrating the liquid nutrient liquor to prepare concentrated liquid nutrient liquor; mixing the fermentation liquor solid wet base with feed raw materials, pure water, compound strain liquor and compound enzymes, and performing enzymolysis fermentation, so as toprepare fermented and enzymatically hydrolysed solid wet bases; mixing the fermented and enzymatically hydrolysed solid wet bases with the concentrated nutrient liquor to prepare the fermentation feedrich in volatile fatty acid calcium. The prepared feed is rich in nutrients of the volatile fatty acid calcium, mycoprotein, active small peptides, oligosaccharides, probiotics and the like, and hasthe efficacy of stimulating lactation, promoting digestion, increasing food consumption and the like.

Description

technical field [0001] The application belongs to the field of feed, enzyme preparation and microorganism technology, and in particular relates to a method for preparing rumen-derived microbial fermented feed rich in volatile fatty acid calcium. Background technique [0002] Rumen microbial fermentation and its nutrition have been a hot research topic in ruminant nutrition for many years. The rumen is the first stomach of ruminants near the esophagus, with a volume of about 70-120 liters. It can be regarded as a continuous inoculated active fermenter for the reproduction of anaerobic microorganisms. In a sense, people feeding ruminants are actually feeding the microbes in their rumens. The research found that: rumen microorganisms mainly include bacteria, fungi and rumen protozoa. Bacteria include: fiber-degrading bacteria, hemi-fiber-degrading bacteria, starch-degrading bacteria, protein-degrading bacteria, fat-degrading bacteria, acid-utilizing bacteria, lactic acid-prod...
