Traditional Chinese medicine preparation for treating porcine respiratory disease syndrome and preparation method thereof

Abstract

The invention discloses a Chinese medicinal preparation for treating porcine respiratory disease syndrome and a preparation method thereof. Every 100 parts by weight of the Chinese medicinal preparation is prepared from the following major raw materials in parts by weight: 10-30 parts of liquorice root, 20-50 parts of pummelo peel and 30-60 parts of heartleaf houttuynia herb. The preparation method comprises the following steps of: putting liquorice root, pummelo peel and heartleaf houttuynia herb into an extraction tank, adding water of which the amount is 6-10 times the total amount of liquorice root, pummelo peel and heartleaf houttuynia herb, slightly boiling at 98-99 DEG C for performing reflux extraction, filtering an extracting solution, and concentrating a filtrate into a thick paste of which the relative density is 1.2-1.25; adding the obtained thick paste into cane sugar and dextrin, mixing uniformly, preparing into particles, drying, and preparing into 100 parts by weight to obtain Chinese medicinal particles for treating porcine respiratory disease syndrome. As proved by clinical test, the cure rate of the Chinese medicinal preparation serving as an effective prescription for treating porcine respiratory disease syndrome and the like can be over 85 percent; and moreover, the Chinese medicinal preparation is free from medicament tolerance, and has a good clinical effect.

Description

technical field [0001] The invention relates to veterinary drugs, in particular to a traditional Chinese medicine preparation for treating porcine respiratory disease syndrome and a preparation method thereof. Background technique [0002] Porcine respiratory disease syndrome is a disease characterized by reduced growth rate, reduced feed utilization rate, loss of appetite, cough, and dyspnea. Although the overall mortality rate is not high, it will seriously affect the economic benefits of pig farms. [0003] At present, porcine respiratory disease syndrome has some new features. First, the pathogens of mixed infection have changed compared with previous years. The pathogens are Mycoplasma pneumoniae, reproductive and respiratory syndrome virus (PRRSV), and type 2 circovirus. (PCV-2) and other infections, combined with secondary or mixed infections of other bacteria. The second is the change of the onset time, showing that pigs at all stages after weaning can be sick, that...
