The hazard of parasites is not only to seize the nutrients, cause the lack of nutrition in the pigs and slow the growth rate. The most serious problem is that the parasites in the body and the outside can cause the spread of the disease. Parasites can spread viral diseases, bacterial diseases and protozoa diseases. The way they spread is to cause pigs to injure themselves first (the pig causes porcine dermatitis, causes itch in pigs to cause extracorporeal injuries) and in vivo (wounds left by parasites such as ticks are sucked by mouthparts), resulting in Viruses, germs, and protozoa are transmitted in large numbers, so large-scale pig farms must be strictly deterred. Spring is the season for the recovery of all things. The parasites have also begun to multiply. In this season, large-scale pig farms must do a good job of deworming.

Common mistakes when deworming

Emphasis on fattening pigs to repel insects and not pay attention to the sows' deworming. Sows are parasitic insects and transmission sources of parasites in pig farms, and it is important for sows to repel parasites, especially sows that are prenatally driven by insects, to better block the spread of parasites from sows to sows.

It is considered that a large dose of anthelmintic is better than multiple small doses. At present, the broad-spectrum, high-efficiency, and safe anthelmintic drugs that are actually applied are often better than multiple low-dose additions at a large dose.

Some pig farmers do not clean the pigs after they have been dewormed, and the discharged eggs are eaten by pigs. The correct method is to clean up the excrement in time after deworming, stack fermentation, incineration or deep treatment. The floor, walls and feedstuffs of the barn can be disinfected with 5% lime water.

Principles of scientific deworming

Choose insecticides with exact killing effect, low toxicity and high efficiency

There are many types of parasites, their structures, characteristics, and locations of their parasites are different. The pathogenic effects and clinical symptoms of affected pigs are also different. Therefore, we need to choose the right medicines, get the medicines, and pay attention to the choices. Low-toxic and highly effective drugs.

There are many kinds of insect repellent drugs on the market, but Weiyuan Jinyiwei produced by Weiyuan Company is a compound preparation that can drive off both internal and external parasites (nematodes, aphids, cockroaches, cockroaches, etc.); It is self-developed and produced; specifications, dosage forms are complete, easy to use and safe; the processing technology is advanced atomized spray process, and the special organic carrier (non-fat corn cob) does not hurt the stomach and has good palatability.

The dosage should be accurate

Where de-worming drugs have a certain degree of toxicity, the amount of excessive use of the pig poisoning, too little can not kill the parasite. Therefore, the dosage must be according to the instructions of the medicine or follow the instructions of the veterinarian. The usage of Weiyuan “4+2” model: Sows: Weiyuan Jinyiwei (0.2%) 500 kg per kilogram of spices; Finishing pigs: Weiyuan Jinyiwei (0.2%) 1000 kg per kilogram of spices. Can not arbitrarily increase the amount of medication.

Grasp the opportunity to take the drug in time

The appropriate timing for the treatment of parasites in vivo and in vitro should be mastered:: Weiyuan's usage of the “4+2” model:

Sows: Insects are repelled once every 3 months for 7 days, ie four times a year.

Finishing pigs: One drive 15 days after weaning, 30 kg to 40 kg drive again, each for 7 days, ie, drive twice a year.

Pay attention to the management of deworming pigs

For pigs that inject deworming medicines, they must be carefully observed. Once side effects occur, they must be dealt with promptly. After the deworming, the pens must be completely cleaned up, the old litter is burned in a concentrated manner, and the excrement is concentrated and fermented so as to kill the eggs and prevent the spread.
