Selection of drugs for Porcine parasites
There are many kinds of deworming drugs for pigs, but we should choose drugs with fast effect, easy to use, cheap, low toxicity and no drug resistance, as long as we choose them properly, we will get the effect of deworming. Anthelmintic drugs are divided into anti-nematode drugs, anti-trematode drugs, anti-tapeworm drugs and antiprotozoal drugs. Due to the different properties of the agents, even the anti-nematode drugs are not effective against all nematodes. For example, levamisole and albendazole are ideal nematode repellents at present, which are cheap, safe and reliable with low toxicity. Moreover, it is an immune enhancer, which can enhance the immune function of pigs, and has a good deworming effect on porcine pulmonary filariasis, Ascaris lumbricoides, colorectal nematodes and esophageal mouth nematodes, but not stable on porcine kidney worms.
Insect repellents are divided into tablets, powders, injections and emulsions. Generally speaking, powder and tablets are suitable for digestive tract parasites, injection is suitable for parasites in respiratory system and liver, kidney and other organs, and emulsion is more appropriate to control ticks, mites and other external parasites.
It is best to choose some traditional Chinese medicine insect repellent, first, it has small side effects; second, it will not produce drug resistance, and how many times it can be used will not affect the effect of insect repellent; third, long-term use will not produce harmful residues, in line with health standards; fourth, it is highly targeted, two-way regulation, wide indications, can enhance immune function; fifth, the price is cheap. Such as Ascaris lumbricoides can be used Gentleman Ren San, pumpkin seed powder, Taiping San, etc., pig cysticercosis can use pomegranate peel soup; external parasites, such as pig lice mashed with fresh peach leaves, rub on the pig body several times, pig scabies can be cured with waste machine oil.

How to do well the immunity of reserve pigs
1. The production and importance of good immunity of reserve pigs after the first injection of vaccine to pigs, the corresponding antibodies will be produced after a certain period of time, at this time, the antibody titer is low, the maintenance time is short, and they do not have the ability to resist pathogen invasion. but it laid the foundation for the establishment of effective immunity in the future, so it is called basic immunity. Re-inoculation of the same vaccine in a certain period of time can induce the recall response of memory cells after the first vaccination, which can quickly produce high titer and maintenance time in a short period of time.
