How to determine the deworming effect of pigs?

Many pig farmers do not know how to judge whether their pig parasite infection is serious, or just rely on their eyes. Here are two simple and accurate methods for detecting parasite infection and testing the effect of deworming drugs. I hope you can master it skillfully. To judge whether the effect of parasite infection and deworming in pig farms is ideal, the scratching index method and saturated salt water floating method are generally used.

The main results are as follows: 1. the scratching index method is used to detect the infection degree of scabies mites on the body surface and to test the effect of killing scabies mites. The tickle index method refers to the static observation of a group of pigs (not less than 30), and the total number of scratches within 15 minutes divided by the number of pigs. (that is, 30 pigs, the total number of itching within 15 minutes divided by 30, that is, the itching index) 1. The itching index of severe infection is more than 0.4. 2. The scratching index of moderate infection is 0.1 / 0.4. 3. The scratching index of mild infection is less than 0.1. Note: if the itching index decreases significantly after using deworming drugs in pig farms for 7 days, it proves that the deworming effect is obvious. 2. Saturated salt water floating method is used to detect the infection degree and deworming effect of Ascaris lumbricoides, spinocephalus, esophageal nematodes, pulmonary filariasis, porcine kidney worms and so on. The main results are as follows: 1. The number of eggs in the feces of severely infected pigs is more than 5000. 2. The number of eggs in the feces of one gram of moderately infected pigs was 500, 000. 3. The number of eggs in the feces of mildly infected pigs is less than 500. No matter in vivo parasite, body surface parasite, moderate infection or more, must carry out deworming. Note: before the use of deworming drugs in pig farms, if the number of eggs is more than 500 / g, after the use of deworming drugs, there is no adult excretion, and the number of eggs decreased significantly, it is proved that deworming is effective. Preparation of saturated salt water: after boiling water in the container, slowly add salt and stir from time to time until the salt is no longer dissolved, the liquid after cooling is saturated salt water. 100 ml boiling water is about 35-40g salt.
