Parasitism is a specific relationship that occurs between the parasite and the host under certain conditions. The parasite enters the host, causing different damage to the host; at the same time, the host's response to the parasite is to produce different degrees of immunity to try to clear it. As a result, parasites may cause changes in morphology and function, and pathological changes may occur in the host. The loss caused by parasites is a loss in production performance, such as reduced growth rate and reduced feed return. However, the hidden loss is even more alarming, such as causing sow reproductive disorders, spreading blood infectious diseases, and especially affecting the immune effect of vaccines. There are several common mistakes people make in deworming pigs:
1. Emphasis on deworming in fattening pigs and not in sows. Sow is a carrier and transmission source of parasites in pig farms. Attention to sow deworming, especially sow prenatal worms, can better block the transmission of parasites from sows to sows.
2. Ivermectin is considered to be a versatile anthelmintic. Ivermectin is a semi-synthetic macrocyclic internal vinegar multi-component antibiotic produced by the fermentation of Streptomyces avermitilis. It has a good killing effect on internal and external parasites, especially nematodes and arthropods. It has no effect on roundworms, flukes and protozoa.
The editor of Somaki believes that a large dose of insect repellent is better than multiple small doses. At present, the broad-spectrum, high-efficiency, and safe deworming medicines used in practice are often added in small doses more than once in large doses.
