Natural plant small molecular group substance concentrate and production method thereof

Abstract

The invention discloses a natural plant small molecular group substance concentrate and a production method thereof. The production method comprises the following steps: harvesting the natural plantsof tall hemarthria, trefoil, ryegrass, purple amaranth and swiss chard respectively, washing, carrying out ultraviolet disinfection, pulping, carrying out ultrasonic crushing, squeezing, filtering andobtaining juice; putting the obtained juice into a fermentation tank according to the ratio of 30-40% of tall hemarthria, 20-30% of trefoil, 10-15% of ryegrass, 10-15% of purple amaranth and 10-15% of swiss chard to be used as a reaction substrate, inoculating with secondary culture liquid of the strains of plant lactobacilli (with the serial number of SICC1.518) and aspergillus niger bacteria (with the serial number of SICC3.301) into the fermentation tank, mixing with the plant juice of the reaction substrate, fermenting and culturing for 72 hours, regulating and controlling the temperatureat 35-37 DEG C, regulating and controlling the pH value at 6.5, obtaining fermented culture liquid, drying the fermented culture liquid at low temperature of 70-80 DEG C after purifying, ultrafiltering and concentrating, and obtaining the small molecular group substance concentrate. Experiments prove that the effects of the concentrate for promoting the growth of fattening pigs and enhancing thefeed conversion rate are respectively 20% and 11.8%, and the effects of the concentrate for promoting the growth of fattening meaty ducks and enhancing the feed conversion rate are respectively 7% and9.7%.

Description

Technical field

[0001] The invention belongs to the technical field of feed and feed additive industry, and in particular relates to a natural plant small molecule group substance concentrate and a production method thereof. Background technique

[0002] The international animal nutrition and breeding community believes that the serious health problems existing in the current intensive livestock and poultry breeding are the relatively single feed ingredients and the long-term insufficient intake of natural trace disease-resistant substances. The principle is that many important physiological and biochemical processes in animals are mediated and completed by the mutual recognition of organic active small molecules and biologically active macromolecules. In the process of animal evolution, these small molecular substances and biological macromolecular substances formed an inherent mode of mutual regulation and became part of animal life activities. These biologically active macrom...
