Embodiment 1

[0021] (1) Preparation of myrtle root extract

[0022] a. Boiled extraction: 50 parts of myrtle root decoction pieces were crushed, added water 5 times according to the weight ratio, boiled for 2 hours, extracted 3 times, collected the medicinal liquid, filtered; the filtrate was vacuum concentrated into an extract at a ratio of 1:4.

[0023] b. Gradient alcohol precipitation and drying: add 95% ethanol to the extract obtained in step a until the final concentration volume fraction of ethanol is 20-30%, let it stand in a cool and dark place for 24 hours, filter the supernatant, and discard the precipitate Continue to add 95% ethanol to the supernatant until the final concentration of ethanol is 70% by volume, let it settle in a cool and dark place for 24 hours, take the supernatant and filter it, and recover the ethanol from the filtrate under reduced pressure; the precipitate is vacuum-dried at 60-70°C, Myrtle root extract A was obtained.

Abstract

The invention relates to a Chinese herbal medicine oral liquid for treating piglet diarrhea. The Chinese herbal medicine oral liquid is prepared through the steps: by taking 40-60 parts by weight of dried medicinal material downy rosemyrtle root and 20-30 parts by weight of dried medicinal material herba fibraureae recisae, obtaining a downy rosemyrtle root extract through poach extraction, gradient alcohol precipitation and drying, obtaining a coarse herba fibraureae recisae product through percolation extraction, precipitation and drying, and adding water to the downy rosemyrtle root extract and the coarse herba fibraureae recisae product to prepare the Chinese herbal medicine oral liquid. The Chinese herbal medicine oral liquid for treating piglet diarrhea is wide in raw material source, simple and easy in production process, low in energy consumption, easy to control in quality, stable in quality of product, and applicable to large-scale production.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a Chinese herbal medicine oral liquid for treating piglet diarrhea and a production method thereof. Background technique [0002] Piglet diarrhea caused by pathogens such as Escherichia coli, B. hyodysenteriae, porcine epidemic diarrhea virus (PEDV) and porcine transmissible gastroenteritis virus (TGEV) is a typical multi-pathogenic disease under intensive pig production conditions , is one of the most serious disease groups of piglets, and is an important factor affecting the survival rate of piglets; according to the survey, piglets died of diarrhea accounted for 39.8% of the total number of piglet deaths; rate 10.3%. Piglet diarrhea ranks first among the hazards of the pig industry, which seriously threatens the healthy development of the pig industry and seriously affects the economic benefits of the pig industry in my country. Diarrhea in piglets often leads to...
