Composite feed additive for replacing antibiotics to prevent and control chicken coccidiosis

Abstract

The invention discloses a composite feed additive for replacing antibiotics to prevent and control chicken coccidiosis. Aiming at the pathogenesis, the pathogenetic condition and the symptoms of the chicken coccidiosis, starting from the aspects of increasing the immunity, killing parasites, stop bleeding, diminishing inflammation, repairing the intestinal tract and the like, dichroae radix, radixbupleuri, sweet wormwood herb, flos imperatae, folium artemisiae argyi, pollen typhae, montmorillonite, licorice roots and other Chinese herbal medicines for killing the parasites, stopping bleedingand diminishing inflammation are selected to be scientifically compounded, multiple vitamins, egg fetus powder, selenium yeast, glycine zinc and other nutrient substances with immune functions are selected to be compounded, and the composite feed additive has the functions of resisting the parasites, killing the parasites, conditioning the body and the like. Through experiments of artificial infection of coccidiosis, it is shown that after the feed additive is used, the surviving rate of broiler chicken can reach 99%, and the number of coccidian oocysts is reduced along with prolonging of theinfection time.

Description

technical field [0001] The invention belongs to the field of animal nutrition and relates to a feed additive, in particular to a feed additive for replacing antibiotics to prevent chicken coccidiosis. Background technique [0002] Chicken coccidiosis is caused by various coccidiosis of Eimeriaceae and Eimeria genus parasitic on chicken intestinal epithelial cells, with enteritis, emaciation, anemia, bloody diarrhea, lethargy, coma, feet and Wing paralysis and other parasitic diseases as the main symptoms. The course of the disease is 1-3 weeks, and it mostly occurs in 15-50 day-old chicks. The incidence rate is 50%-70%, and it is as high as 80% in severe cases. In my country, the annual economic loss caused by coccidiosis is as high as 3.5 billion yuan. . At present, chemical drugs can no longer completely remove coccidia in chickens, and a series of secondary problems have arisen, such as increased drug resistance of coccidia, decreased immunity of chickens, food safety ha...

Problems solved by technology

At present, chemical drugs can no longer completely remove coccidia in chickens, and a series of secondary problems have arisen, such as increased drug resistance of coccidia, decreased immunity of chickens, food safety hazards caused by drug residues, etc.

[0003] In recent years, some progress has been made in the application of Chinese herbal medicines to the prevention and treatment of coccidiosis. However, no matter whether it is a single medicine or a compound medicine, the Chinese herbal medicine anticoccidiosis only stays in the field test and the comparison test of the efficacy of western medicine, and has not completely replaced antibiotics.
