preparation example Construction

[0025] A kind of preparation method of gourd tea extract feed additive, concrete steps are as follows:

[0026] Step 1. Shorten and clean 2-4 parts of the whole herb of gourd tea;

[0027] Step 2, 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;

[0028] Step 3, filtering after the first alcohol extraction to obtain the first filtrate and the first filter residue respectively; wherein, the first filtrate reclaims ethanol through a decompression concentration tank until the recovered ethanol is <60% and stops recycling, and the first filtrate continues to concentrate to obtain Concentrate;

[0029] Step 4: Add 3 to 6 times the weight of 60% to 90% ethanol to the first filter residue for the second time, boil for 3 to 6 hours, the steam pressure is 0.4 to 0.7 MPa, and the ethanol is refluxed until the recovered ethanol is less than 6...

Abstract

The invention discloses a desmodium triquetrum extract feed additive and a preparation method of the desmodium triquetrum extract feed additive. The desmodium triquetrum extract feed additive is obtained through cyclically extracting desmodium triquetrum hibiscus trionum for many times and then uniformly mixing the desmodium triquetrum hibiscus trionum on the carrier. The preparation method comprises the following steps of: 1, primarily extracting the desmodium triquetrum hibiscus trionum; 2, cyclically extracting reset materials extracted in the first step for many times, carrying out spray drying treatment on the obtained extract, and then, uniformly mixing the extract with the carrier for forming the desmodium triquetrum extract feed additive. The desmodium triquetrum extract feed additive has the functions of clearing away the heat to realize disintoxication, promoting diuresis to removing jaundice, resolving depression to climb oldenlandia, relieving asthma and cough, eliminating accumulation to remove parasites and enhancing the animal immunity.

Description

technical field [0001] The invention relates to a gourd tea extract feed additive and a preparation method thereof. It has the functions of clearing away heat and detoxification, promoting dampness and reducing jaundice, relieving stagnation and regulating the lung, relieving asthma and relieving cough, eliminating stagnation and killing insects, and enhancing animal immunity. It belongs to the technology of natural plant additives field. 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 r...
