Embodiment 1
[0036] Effects of different excipients and their combination on the processing technology of micro-powder of vonemulin
[0037] Ingredients: Warnemulin Hydrochloride, Aluminum Stearate, Talc, Wheat Bran, Rice Husk
[0038]Experimental method: take wheat bran and rice husks, stir-fry them with a slow fire until they are browned according to the traditional Chinese medicine method, and pulverize them for later use; take the materials according to the weight of each anti-caking agent component in Table 1, mix them fully and add them to 90 parts of hydrochloric acid Pulverize in a sealed low temperature (≤50°C) in Wernimulin, prepare samples 1 to 13, and pass the obtained samples 1 to 13 through a 200 mesh sieve respectively, record the time for all the powders to pass through the 200 mesh sieve, according to the The time of the test is recorded as "+++++" to "+" in order from short to long, and it is recorded as "-" if it cannot pass all of them (see Table 1 for the results).

Embodiment 2
[0089] Investigation of the curative effect of new-type wonimulin premix on swine panting disease:
[0090] Product: with existing commercially available " warnemulin hydrochloride premix " as contrast; According to the product quality evaluation result of embodiment 1, choose the sample 59 prepared in embodiment 1 as the novel warnemulin premix for testing agent products.
[0091] Case: 90 panting pigs with natural onset in a pig farm in Leshan (short and continuous coughing of pigs, which are most likely to be heard when stimulated by cold air after leaving the pen in the morning, or before and after driving and feeding, and coughing at the same time A small amount of nasal clearing fluid, grayish white viscous or purulent nasal fluid when seriously ill).
[0092] Method: Under the same feeding conditions, the diseased pigs were randomly divided into positive control group, test group and negative control group; the positive control group was fed with 0.3% mixing material o...
