Description

Pig raising method for preventing pig coccidiosis

Technical Field

The invention relates to the field of pig breeding, in particular to a pig raising method for preventing pig coccidiosis.

Technical Field

The coccidiosis of pig is caused by Eimeria (A)Eimeria) And Isospora (Isospora) Caused by coccidia. The life history of the porcine coccidia is the same as that of coccidia of other animals, the porcine coccidia is propagated in two generations of asexual generation (merozoite reproduction) and sexual generation (gametophyte reproduction) in a host body, and sporulation is carried out in an external environment. Host cells are damaged by merogenesis, gametogenesis and oocyst release. Since each merozoite contains a large number of merozoites and several generations of merozogenesis may occur, 1 oocyst engulfed has the ability to destroy thousands or millions of intestinal cells. The generation number of asexual reproduction and the number of merozoites released by the schizonts, as well as the time required to complete the life cycle, vary with the species of coccidia. The number of asexual generations, the number of merozoites produced, and the latency period for each species remained relatively stable. Thus, each coccidia has the potential to destroy a certain number of host cells. This may be one reason why some coccidia species are more pathogenic than others.

The coccidiosis of the piglets is distributed worldwide, mostly occurs to piglets of 7-21 days old, the main symptoms are diarrhea, the growth is slow, the severity of the symptoms of the piglets in different litters is different, and even the affected degree of different individuals of the piglets in the same litter is different. The disease has high morbidity and low mortality, is easy to generate secondary infection, causes higher morbidity and mortality, has ineffective treatment by antibiotics, and is frequently ignored by pig breeders and veterinarians, thus seriously affecting the economic benefit of a pig farm.
