Chicken coccidiosis is the most common, invasive and harmful intestinal parasite protozoon in the modern intensive chicken industry. Its control is difficult, the incidence is 50%-70%, and the mortality is as high as 80%. , to the chicken industry caused great economic losses. In the summer and fall season, it is the high season of chicken coccidiosis. In the past few days, the readers with phone numbers 3668, 7665, and 2157 have come to inquire about the prevention and treatment of chicken coccidiosis. Therefore, we publish this article and hope to have Helped.
Chicken coccidiosis is a kind of chicken intestinal protozoal disease caused by several species of Eimeria. The incidence and mortality of chicks are high, and the harm is extremely serious, resulting in dysbacteriosis of the intestinal flora and increased susceptibility to diseases. The growth of chickens is hindered, the feed conversion rate is decreased, the cost of medications is increased, and economic losses are serious. High temperatures and high humidity in summer and autumn create good environmental conditions for the development of coccidial oocysts in vitro. Therefore, the prevention and control of chicken coccidiosis in summer and autumn is of great significance for increasing feeding efficiency and reducing losses. The following issues should be noted in production:
Strengthen the feeding and management of coccidiosis as an intestinal protozoal disease, mainly by the chickens feeding on the sporulated oocysts to carry out asexual and sexual reproduction in the intestinal mucosal epithelium, producing new oocysts. After the sac was drained to the outside of the body, the sporulated oocysts developed in 1-3 days under appropriate environmental conditions (temperature 20°C-30°C, humidity 40%-60%), and were infected by other chickens after eating. Therefore, strengthening hygiene, disinfection and related management measures in the feeding and management process can effectively prevent the occurrence of coccidiosis.
Feeding mode: adopt all-in, all-out feeding mode. Chickens of different ages should not be polycultured.
Feeding methods: During brooding, it is best to adopt online raising or cage culture to separate chickens from feces to effectively reduce the incidence of coccidiosis. If ground level raising is adopted, it is necessary to promptly remove the chicken manure. It is best to clean the manure once every 1-2 days and ferment the excrement to cut off the spread of coccidiosis.
Strengthen disinfection: Coccidial eggs have strong resistance to the outside world. Generally, disinfectants cannot completely kill mature oocysts and can only weaken the virulence of mature oocysts. Therefore, it is necessary to strengthen the cleaning and disinfection work, especially the cleaning and disinfection before entering the young.
Do a good job in sanitation and ventilation work: The oocysts of coccidia must be infective after they have been sporulated by the outside world. Therefore, do a good job of hygiene, keep it dry and ventilated, remove the feces in time and build up fermentation, kill the oocysts, will greatly reduce the chance of infection. To keep feed and drinking water clean and prevent it from being contaminated; reduce feeding density, increase ventilation, reduce indoor humidity, replace wet litter in a timely manner, and gradually reduce humidity after brooding for 10 days, which can effectively reduce the incidence of coccidiosis; Keeping staff in and out of the house should change shoes, and equipment and equipment should be promptly cleaned and disinfected to reduce the number of coccidia eggs and the opportunities for transmission in the environment.
Strengthen the nutrition and enhance the resistance of the chicken: Supplementing vitamin A, vitamin K 3, etc. in the feed can accelerate epithelial cell repair and have hemostasis, thus promoting the improvement of the disease.
The use of good drugs in actual production, farmers often because of unreasonable drug selection, blind use of drugs, so that coccidiosis resistance, resulting in poor efficacy, or even invalid. Therefore, use drugs.
Early medication prevention: Coccidial eggs have strong resistance and are widely distributed. It is difficult to control coccidiosis simply by sanitizing hygiene. Therefore, early drug use must be prevented to reduce coccidiosis. The chicks were prophylactically treated with anticoccidial drugs every 7-10 days starting at the age of 10 days for 3 days.
Rational selection of drugs: There are a wide variety of anticoccidial drugs currently available in the market, and the choice is relatively large. However, the peak period of action and effective insect species of each drug are not consistent, and the taboos and synergistic effects of various drugs are not exactly the same. The safety is also very different, so when choosing anticoccidial drugs, consider the purpose of the drug first. When used for prevention, it can be used as a drug for vegetative propagation, such as cloni powder, chlorpheniramine, and as a second-generation schizont drug, such as sulfachlorpromazine sodium. In addition, the characteristics of drug resistance in chicken farms should also be taken into consideration, and drugs should be selected rationally.
Rotating medications, shuttle medications and combination medications: Rotating medications, that is, in a farm, changing medications according to different seasons or on a regular basis. Shuttle medication, that is, within one feeding cycle, using two or more anticoccidial drugs, starting with an anticoccidial drug, using another drug during the growth phase, and chemically synthesizing the anti-ball Insecticide and ionophore anticoccidial drug shuttle application. Combined use of drugs, that is, the simultaneous use of several drugs, the use of synergies between drugs to enhance efficacy, and more for the treatment of coccidiosis.
Selecting sensitive Chinese medicines to reduce drug residues: In the clinic, traditional Chinese medicines with insect repellent, insecticidal, hemostatic, detoxifying, and anti-inflammatory effects can be selected to effectively suppress the development of coccidia, which can play a preventive and therapeutic role, while reducing chemical drugs. Residues. Such as Artemisia annua, Changshan, Forsythia, Bupleurum, Sophora flavescens, Agrimony, habitat, Pulsatilla, Atractylodes, Plantago and other traditional Chinese medicines, all have the effect of inhibiting coccidia.
The use of coccidiosis vaccine cocci vaccine can stimulate the body to produce effective immunity. The use of coccidiosis vaccine in chicken farms for immunoprophylaxis can not only control the occurrence of coccidiosis, but also solve the problem of long-term use of chemical drugs. Coccidial attenuated virus vaccine breeds in chickens and discharges them to weak oocysts in vitro, which can purify and reduce pathogenic oocysts. Pathogenic oocysts can be vaccinated in chicken farm environment after 2-3 production cycles. The replacement of the source oocysts restores the anticoccidial susceptibility. Therefore, the law is getting more and more attention by the farm. Chicken coccidiosis vaccine immunization route drops, spices, drinking water, etc. Among them, the best effect of the mouth drops immunity. The first free time is 3-5 days old and the latest is not more than 10 days old.
Early diagnosis and early treatment
If coccidiosis is harmful, it will affect the chicken's growth and feed conversion rate. In severe cases, the chicken can die. Therefore, early diagnosis and treatment of coccidiosis should be conducted to reduce losses. It is best to use drugs within 96 hours of infection and use two or more anticoccidial drugs in combination. One, with sulfaquinoxaline, feed at a rate of 0.1% for 2-3 days, stop for 2 days, and then mix with 0.005% for 3 days. Second, with ammonia propriofen, according to the concentration of 0.012% -0.024% drinking water for 3 days. Third, take flavescens, Agrimony, Changshan, and medlar charcoal equal parts by 2% of the ratio of spices, even fed 3-5 days, can play a role in killing insects, only phlegm. In order to improve the therapeutic effect, vitamin A, vitamin K 3 and intestinal anti-inflammatory drugs can be added to the feed.
