preparation example Construction

[0024] A kind of preparation method of loquat leaf extract feed additive, concrete steps are as follows:

[0025] Shorten the loquat leaves and pick them clean;

[0026] Put the raw materials into an alcohol extraction tank, add 3 to 6 times the weight of 60% to 90% ethanol, boil for 3 to 6 hours, the vapor pressure is 0.4 to 0.7 MPa, and the ethanol is refluxed;

[0027] Filtrating after the first alcohol extraction to obtain the first filtrate and the first filter residue respectively; wherein, the first filtrate recovers ethanol through a decompression concentration tank until the recovered ethanol is less than 60% and stops recovery, and the first filtrate continues to concentrate to obtain a concentrate;

[0028] 60%~90% ethanol of 3~6 times of weight is added to the first filter residue for the second time, boiled for 3~6 hours, the vapor pressure is 0.4~0.7MPa, the ethanol is refluxed, until the recovered ethanol<60%, stop recovery, filter, respectively Second filtrate...

Abstract

The invention discloses a loquat leaf extract feed additive and a preparation method thereof. The loquat leaf extract feed additive is prepared by performing circulating extraction on loquat leaves for multiple times and then mixing the extract and a carrier uniformly. The preparation method comprises the following steps of: 1, crudely extracting the loquat leaves; and 2, performing circulating extraction on the residues after the extraction in the step 1 for multiple times, performing spray drying on the extractum obtained in the extraction, and mixing the extractum and the carrier uniformly to prepare the loquat leaf extract feed additive. The loquat leaf extract feed additive has the functions of clearing lung and relieving cough, clearing heat and reducing phlegm, and preventing and treating animal respiratory diseases.

Description

technical field [0001] The invention relates to a loquat leaf extract feed additive and a preparation method thereof, which has the function of clearing the lung and relieving cough, and belongs to the technical field of natural plant additives. Background technique [0002] Pigs of all ages, especially piglets, are characterized by respiratory diseases, which have become one of the main diseases in large-scale pig farms. Among them, the most important porcine respiratory disease syndrome (PRDC) is a disease characterized by reduced growth rate, reduced feed utilization rate, loss of appetite, cough, dyspnea, and diarrhea. Although the overall mortality rate is not high, it can seriously affect pigs. economic benefits of the field. At present, some new features have appeared in respiratory disease syndrome. First, the pathogens of mixed infection have changed compared with previous years. The pathogens are Mycoplasma pneumoniae, reproductive and respiratory syndrome virus (...
