The warm and wet season provides favorable conditions for the reproduction of coccidia. If we want to treat coccidia, the environment must be improved.
The life history of coccidia is generally 4~7 days, the asexuality period is 3~5 days, the sexual reproduction period is 2 days, and the formation of sporulated oocysts in vitro only takes about 1 day.
The wall of the coccidia oocyst has two layers, the outer layer is a protective membrane, strong, with greater elasticity, and the chemical composition is like keratin; the inner chemical composition is lipid-like, and the protoplasm is granular.
Because of such a special protective structure, the resistance of coccidia oocysts is very strong, and they can survive in the soil for 4 to 9 months. Oocysts are extremely resistant to common disinfectants.
Oocysts exist in feed, drinking water, soil, utensils, etc. that have been contaminated by the feces of diseased chickens or chickens with insects. Birds, poultry and certain insects, as well as tube feeders, can be communicators of coccidia.
The warm and humid environment is conducive to the development of oocysts. In the environment of 22 ℃ ~ 30 ℃, the sporulation can be completed in 18~36 hours. Therefore, the treatment of coccidiosis, to the combination of Chinese and Western, alternate use, in order to achieve the best purpose of treatment.
Chicken coccidiosis control measures
In the process of chicken breeding, in addition to the selection of chicken seedlings and feed, scientific and standardized feeding management, disinfection is an effective measure to prevent chicken coccidiosis.
1. Sprinkle or spray 20% lime water or 30% plant ash water or disinfectant (mixed with water according to the instructions) for disinfection in pens, tableware and utensils. Maintain appropriate temperature, humidity and feeding density.
2, the epidemic season, feeding vitamin A, vitamin K to enhance the body's immune capacity, improve antibody levels.
3, the chick period can be used chicken coccidia powder according to the best dose of mixing and feeding for 3-5 days.
4. Coccidia treatment should be administered at regular intervals according to the growth and development of coccidia, and sensitive drugs should be selected according to the category of coccidia.
