CATDOLL : CATDOLL: How to prevent and treat Staphylococcus aureus in chickens?

1. How to prevent and treat staphylococcal disease in chickens?

Staphylococcus aureus treatment. Many antibiotics and sulfonamides can kill staphylococci. For a chicken farm, which drug is the most effective and economical? It is necessary to conduct drug sensitivity tests on the staphylococci isolated in the farm and select the most sensitive drug for treatment to obtain satisfactory results. When the effect of a drug is not satisfactory, another drug should be replaced in time. Commonly used drugs are:

①Gentamicin: 4000 units per head, twice a day, for 3-5 days. ②Kanamycin: 2000-3000 units per head, twice a day, for 3-5 days. Or 4000 units per head in drinking water, for 7 days. ③Penicillin: 50,000-100,000 units per kilogram of body weight, twice a day, for 3-5 days. ④Midecamycin: 0.011% mixed with feed or drinking water, for 5 days. ⑤Sulfadimethoxine: Add 5 grams per kilogram of feed, for 3-5 days. ⑥Supplement 14: 0.2% in drinking water, once a day, for 7 days.

While using medication for treatment, use 0.3% peracetic acid, 0.1% Disinfectant King or 0.5% Bacterial and Virus Hostile Chicken House for disinfection. When the disease occurs, disinfect twice a day, once in the morning and once in the afternoon, with a dosage of 20 to 30 ml of disinfectant per square meter.

2. What diseases are chickens prone to and how to treat and prevent them?

(I) Fowl plague Fowl plague is an acute septicemia caused by a virus. It usually occurs in spring and autumn, is fast-spreading, and has a high mortality rate. The disease is latent for 3-5 days. It is divided into three types: the most acute type, the acute type, and the chronic type. Generally, the initial outbreak is acute. Main symptoms: fever (43-44°C), closed eyes, loose hair, shrinking neck, drooping wings, unstable gait or turning in circles; black and purple crown, mucus in the mouth, shaking head, gurgling, making "cluck, cluck" sounds, difficulty breathing, and pulling green or yellow feces; in the later stage, the legs and wings are paralyzed, and the mortality rate is high. Prevention: The most reliable method is vaccination. 1. Vaccination: For chicks aged 1-2 weeks, use the Newcastle disease II vaccine diluted 10 times and drip into the nose; repeat it once every 10 days; for medium and large chickens over 2 months old, use the I vaccine diluted 1000 times, and inject 1 ml intramuscularly for each chicken, which can be immune for one year. 2. Drinking water immunization method: Dilute the chicken Newcastle disease III (F) vaccine into a 0.1-0.3% aqueous solution, let the chicken eat freely, and drink it again after 10-30 days, which can be immune for 7 months. 3. Strictly block the epidemic area and disinfect it thoroughly. There is no specific drug treatment for this disease at present. You can try: 1. 3-5 pieces of garlic, smash and mix with a small amount of sulfur powder and raw oil and take it orally twice a day. 2. Smash half a grain of croton (available in pharmacies, toxic, strictly control the dosage) and mix with a small amount of raw oil and take it orally twice a day. 3. Dilute the chicken Newcastle disease I vaccine 500 times, inject milliliters into the muscle of each sick chicken, and it has a certain effect. According to the information: For sick chickens with neurological symptoms, they usually recover 2-3 days after injection. (II) Fowl cholera Fowl cholera is a highly contagious disease, generally with sporadic local epidemics, which can occur all year round. It is sometimes more contagious than fowl plague, and often causes sudden death without any symptoms. This disease can infect ducks and rabbits at the same time. Prevention: Regularly inject fowl cholera vaccine every year. For chickens over 2 months old, regardless of size, inject 2 ml intramuscularly (or subcutaneously) for each chicken, and once every 4-6 months for vaccination; you can also add 0.01% potassium permanganate (manganese dioxide) or 0.2% sulfadimethoxine sodium aqueous solution to the drinking water, which also has a certain preventive effect. Treatment: 1. Penicillin 30,000-50,000 international units per chicken, for intramuscular injection, 3 times a day. 2. Sulfathiazole sodium or sulfadimethoxine sodium intramuscular injection, 1 gram per chicken each time (each tablet contains 250 mg), 2-3 times a day. The above drugs have definite efficacy, but the cure rate is lower after the chicken turns black and purple. (III) Pullorum Pullorum is a bacterial infectious disease that can affect both large and small chickens, but it is more common in chicks around half a month old, with a high mortality rate. Main symptoms: sick chicks are listless, have shrunken heads, drooping wings, and pass white, paste-like loose feces. Their anuses are often stuck with feces, and they make "squeak, squeak" sounds when they defecate. Adult chickens are mostly trapped carriers, and only in severe cases can they have anemia and diarrhea, and the egg production of hens is significantly reduced. Treatment: 1. Add 200-400 mg of furazolidone (i.e. 2-4 tablets) per kilogram of feed, mix well and feed the chickens, use it for 7 consecutive days, stop for 3 days, and then feed for another 7 days. 2. Feed 200 mg of oxytetracycline (or chlortetracycline, tetracycline) per kilogram of chicken body weight (each tablet contains 250 mg); or add 2-3 grams of oxytetracycline (i.e. 8-12 tablets) per kilogram of beverage, mix well and feed the chickens, use it for 3-4 consecutive days. 3. Each chicken should be fed with 2000 international units of penicillin per day for 7 consecutive days. 4. Add 10 grams (i.e. 20 tablets) of sulfaguanidine (or iodine pyrimidine) or 5 grams (i.e. 10 tablets) of sulfamethoxazole (or iodine pyrimidine) per kilogram of feed and feed the chickens for 5 consecutive days; streptomycin or chloramphenicol can also be added to the drinking water at 0.1-0.2% for 7 consecutive days. It is best to use the above drugs alternately to improve the efficacy. (IV) Main symptoms of chicken mycoplasma disease (chronic respiratory disease): respiratory rales (easier to hear at night), runny nose, coughing and sneezing; loss of appetite and weight loss. In the later stage, it is common to see swelling of the eyelids, protrusion of the eyes like tumors, and atrophy of the eyeballs due to pressure, causing blindness. The course of the disease is one to several months. Prevention: Disinfect regularly and keep the chicken house clean; use 2000 units of streptomycin drops in the nose for each hatched chick. Treatment: 1. Streptomycin: 90,000 units for chicks, 100,000 units for medium-sized chickens, and 200,000 units for large chickens for intramuscular injection, 3 times a day, for 3-5 consecutive days. 2. Add 400-800 mg of oxytetracycline or tetracycline per kilogram of beverage (each tablet contains 250 mg), mix well and feed the chickens. 3. Qinmiaolin is particularly effective against mycoplasma disease. Add 125-250 mg of Qinmiaolin aqueous solution to 1000 ml of water for chicken diet. (V) Coccidiosis Coccidiosis is a serious and common disease that harms chicks. Chickens aged 15-25 days are most susceptible to infection, and the incidence and mortality rates are very high. The incidence rate is highest in the rainy season, and once the disease occurs, it will cause widespread epidemics. Adult chickens infected with coccidiosis have slightly milder symptoms and rarely die. Main symptoms: The sick chicks first show general weakness and mental depression, like to crowd together, drooping wings, messy hair, eyes closed, sleepy; diarrhea, brown-red bloody feces; pale crown and beard, drink a lot of water, then stop eating, and finally become extremely thin. Prevention: 1. Keep the chicken house clean and dry, and disinfect it regularly. 2. Isolate sick chickens in time and treat them. 3. Add 150-250 mg of furazolidone per kilogram of feed (each tablet contains 100 mg, mix well and feed to chickens, use for 7 consecutive days, stop for 3 days, and then use the medicine for 5-7 days. Treatment: 1. Use 3000-6000 units of penicillin for each chicken. Dissolve penicillin in water, then use half of the solution to mix powder and feed, and pour the other half into the waterer, but replace drinking water, and let the chickens eat freely. 2. Feed each chick with 2-4 mg of oxytetracycline or chlortetracycline (each tablet contains 250 mg) per day for 3 consecutive days; or add 800 mg of chlortetracycline per kilogram of feed, mix well and feed to chickens. 3. Add 250 mg of furazolidone (i.e. 2.5 tablets) per kilogram of feed, mix well, feed, or add the same dose group of chickens in drinking water for 2-3 consecutive days. (VI) Fowl pox (fowl diphtheria) Fowl pox is a highly contagious disease. Sick chickens grow slowly or even die. The incubation period of this disease is 4-8 days. There are two types: skin type and diphtheria type. Prevention: 1. Vaccination vaccine is suitable for chickens of all ages over 7 days old. When using, dilute it 10-50 times with salt water or cold boiled water by weight, and use a pen tip (or a large needle tip) to dip the vaccine and stab it subcutaneously in the bloodless part of the inner side of the chicken wing. About 7 days after vaccination, the stabbed part will become red, swollen and blistered, and then gradually dry and scab and fall off. It can be immune for 5 months. 2. Maintain good environmental hygiene and eliminate mosquitoes and chicken lice. 3. Isolate sick chickens in time, or even eliminate them, and thoroughly disinfect the site and utensils. Treatment: There is currently no specific drug treatment, and symptomatic treatment is generally used. (VII) Ascariasis Ascariasis is a common parasitic disease in chickens. Prevention: Deworm regularly 3-4 times a year. Treatment: 1. Use 0.15-0.25g of anthelmintic for every kilogram of chicken weight (each tablet contains 0.5g) orally; or grind the medicine into powder and mix it into feed, and feed it once in the evening. 2. Use 20-30mg of anthelmintic for every kilogram of chicken weight (each tablet contains 25mg), mix it into feed and feed it. 3. Use 1-2ml of gasoline for crop injection. For reference only

3. Chicken disease prevention and control?

Improve the feeding environment of the chickens. Wash the feeding troughs and utensils regularly to keep them clean and sanitary. The feed should be high-quality and fresh. When feeding chickens with wet feed, it is easy to become rancid if the feed is left in the feeding trough for too long. Pay attention to it. Keep the environment clean and sanitary, sweep the chicken manure frequently, change the bedding frequently, and disinfect on time. Strengthen the improvement of the feeding environment for young chickens. Because the resistance of young chickens is not as good as that of adult chickens, the sanitary environment of young chickens cannot be ignored. Provide appropriate light. Do a good job of immunization, treat diseases as soon as possible, and specific treatment methods.

1. Infectious bronchitis: Antiviral drug Hu Du Kang combined with respiratory drug Wan Hu Ning. If there is yellow and white stool, take it with E. coli drug Ba Li Ke. Mix it with water and drink it for 4 days.

2. Escherichia coli disease: Escherichia coli drug Bacil.

3. White diarrhea in chicks: Use Changganning to treat white diarrhea in chicks, both for treatment and prevention

4. Identification and prevention of chicken diseases by looking at pictures. The chickens stopped eating when they got sick and later could not stand up. What disease is this?

Being unable to stand up is usually caused by bacterial infection. You'd better tell me the details and I can help you diagnose it.

5. What is the relationship between the anatomical and physiological characteristics of chickens and the prevention and treatment of chicken diseases?

1. The anatomical and physiological characteristics of chickens have nothing to do with disease prevention. Disease prevention is a proactive behavior that takes appropriate measures to prevent chickens from getting a certain disease in the future. For example, making a Newcastle disease vaccine is to allow chickens to produce Newcastle disease antibodies under normal circumstances. If a strong Newcastle disease virus invades the body of the chicken in the future, the antibodies in the chicken will neutralize the strong Newcastle disease virus that invades the body of the chicken, thereby protecting the chicken from Newcastle disease.

2. The anatomical and physiological characteristics of chickens are related to the treatment of diseases in chickens. After a certain strong virus invades the chicken body, it will find the target organ in the chicken body and cause the target organ to develop lesions. Therefore, when dissecting, you can roughly judge what the disease is by seeing the diseased organ tissue. If you want to make an accurate judgment, you need to further examine the pathogenic microorganisms and do some related experiments. For example, the chicken's bursa of Fabricius is the target organ of the chicken bursal disease virus. When the bursa of Fabricius virus invades the chicken body, the chicken's bursa of Fabricius will develop lesions, which are different from normal bursa of Fabricius. Therefore, the anatomical and physiological characteristics of chickens provide a reference for the judgment of treating chicken diseases.

6. How to prevent and control rabbit diseases?

Preventing rabbit diseases means taking effective measures to prevent uninfected rabbits from getting sick. To this end, the following aspects must be done well:

First, scientific feeding and management should be carried out, feed should be properly formulated, attention should be paid to supplementing vitamins and essential mineral elements, the rabbit house and environment should be kept clean and hygienic, feeding tools, cages, farrowing boxes, etc. should be disinfected regularly, and dead rabbits should be handled promptly and safely.

The second is to vaccinate rabbits with rabbit vaccines in a timely manner, and add certain antibiotics and sulfonamides to the feed when necessary to improve the rabbits' disease resistance.

Third, it is necessary to formulate strict disinfection and epidemic prevention systems and specific measures to protect the rabbit population from infection by diseases and prevent them from happening.

Fourth, prevent rabbits from accidentally ingesting toxic substances, do not feed them green fodder contaminated by pesticides and moldy and spoiled feed, and use anthelmintics and other drugs correctly.

7. How to prevent and control sweet potato diseases?

(1) Symptoms are generally divided into two types: mosaic and fern. Symptoms of mosaic are: leaves are yellow and green, leaf shape is irregular, leaf surface is uneven, diseased vines are thin and weak, internodes are shortened, and fruits are deformed. Symptoms of fern are: heart leaves turn yellow, new leaves shrink and deform, small leaves and chicken claw leaves appear, plants are dwarfed, flower organs are poorly developed, and fruit setting is difficult. Fruits infected by the virus have tumor-like protrusions on the peel, are deformed, have hard flesh, have yellow blocks, are of poor quality, and cannot be eaten. (2) Prevention and control methods ① Remove weeds and kill aphids in the field in time to prevent insect transmission. ② Strengthen seed disinfection. Soak seeds in 10% sodium phosphate solution for 20 minutes before sowing, wash with clean water, germinate and sow, and inactivate viruses on the surface of seeds. ③ Strengthen field fertilizer and water management, apply sufficient base fertilizer, apply nitrogen fertilizer in time, strengthen irrigation, increase soil and air humidity, promote plant growth, and reduce damage. ④ Timely control of aphids, beetles, planthoppers, thrips, leafminers, root-knot nematodes, etc. ⑤ Timely early sowing or use simple small arch sheds to advance the fruit maturity and harvest period to avoid the peak of viral disease. ⑥ At the early stage of the disease, spray 500 times of 20% virus A wettable powder, or 1000 times of 15% plant disease emulsion, or 300 times of anti-toxic agent No. 1 and spray 0.2% potassium dihydrogen phosphate to enhance plant resistance. At the same time, remove diseased plants in time to avoid cross infection during manual pruning. ⑦ Choose disease-resistant and disease-resistant varieties, such as Watermelon Antivirus No. 1 and Watermelon Antivirus No. 3.

8. How to prevent and treat diseases of grass carp?

Mud carp disease, also known as "umbilical cord disease" or "umbilical disease", is a disease caused by bacteria that live in fish. It mainly occurs in summer and autumn and in freshwater ecological environments such as rivers, lakes and seas with warmer water. Once the dace is infected with the disease, it will lead to symptoms such as poor development, ulcers, rapid and obvious slow growth and death, so timely prevention and treatment is crucial.

The following are the prevention and treatment measures for fish diseases:

1. Keep the water clean. Dace do not like dirty water, so try to reduce the concentration of sediment and pollutants in the breeding pond, and use biological drugs or high-efficiency bacteria agents to clean it up when necessary.

2. Control the spread of the epidemic. Reduce the possibility of cross-infection, minimize contact between fish during the breeding process, and regularly use disinfectants to clean equipment and other related facilities.

3. Strengthen feeding management. When choosing feed, pay attention to balancing the various nutrients needed by the fish, avoid overfeeding, and pay attention to strengthening daily observation. Once abnormal conditions are found, deal with them in time.

4. Timely drug treatment. If there is an epidemic in dace, appropriate antibiotics and anti-inflammatory drugs can be used for treatment. However, the use of drugs should also follow the principle of rational use of drugs, and follow the dosage, medication time and medication cycle specified in the instructions to prevent the emergence of residues and drug resistance.

In short, the prevention and treatment of grass carp disease requires the adoption of a variety of comprehensive control measures to improve the health level of the fish and ensure the stable development of the aquaculture industry.

9. How to prevent and treat otolith disease?

Otolith disease is a chronic disease that requires multi-faceted prevention and treatment. Otolith disease mostly causes dizziness. If dizziness occurs, take anti-dizziness drugs in time. Otolith disease is mostly caused by otitis media. Be careful not to catch a viral cold, which aggravates ear inflammation and causes otolith disease. Also avoid injuries to the entire head, which can cause dizziness and trigger otolith disease.

10. How to prevent and treat soot disease?

1. Plum orange sooty mold is caused by the nectar secreted by scale insects or aphids. To prevent and control citrus sooty mold, scale insects and aphids must be controlled together to achieve good results. Use fenoxycarb plus methyl thiophanate, or buprofezin plus carbendazim, or thiamethoxam plus chlorothalonil, or acetamiprid plus cephalosporin acetate to spray on the leaves. Pay attention to spraying on cotton scale, aphids and sooty mold, which can kill scale insects and aphids and cure sooty mold.

2. Sooty mold is caused by the nectar secreted by piercing-sucking mouthparts pests such as aphids, thrips, planthoppers, whiteflies, scale insects, etc., and must be disinfected and sterilized at the same time to achieve a good control effect. Foliar spraying of buprofezin plus cintamanib acetate or acetamiprid plus methyl thiophanate or fenoxycarbendazim plus carbendazim or thiamethoxam plus chlorothalonil is very effective. Spray the leaves once every 7 to 10 days, and spray 2 to 3 times in a row to control the occurrence of damage. Add potassium dihydrogen phosphate to spray at the same time for better control effect.
