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

1. 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.

2. Identification and prevention of chicken diseases by looking at pictures. The chickens stopped eating when they got sick and later could not stand up on the plow. 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.

3. 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.

4. How to identify chicken diseases by looking at chicken manure?

Normal chicken manure is in strips, with a layer of white urate on the surface, and moderate hardness. Its color may vary depending on the type of feed, mostly gray-green or sauce-yellow. If it is too hard or too thin, it is caused by insufficient or excessive drinking water. But if it is too soft, it is because there is too much bran and wheat in the feed. If the chicken manure is abnormal in quality, quantity, shape and color, it may be caused by disease.

There are several types of abnormal chicken feces: Flesh-red feces: The shape is like rotten meat, which is formed by the shedding of intestinal mucosa. It is more common in chickens suffering from coccidiosis, tapeworm disease, ascariasis and in the recovery period of enteritis. Bloody feces: The feces are black or dark brown, which is common in upper gastrointestinal bleeding; the feces are red or bright red, which is more common in lower gastrointestinal bleeding. Yellow sulfur feces: The surface of the feces is covered with a layer of yellow or light yellow urine.

That is because the liver lobule is damaged, which affects the excretion of bile, causing bilirubin to enter the blood and be excreted through urine. It is more common in appendicitis and hepatitis. Green sticky and foul-smelling feces: The feces are dark green, which is caused by the mixture of bile and intestinal shed tissue cells. It is more common in fowl cholera, Newcastle disease, laryngotracheitis, etc. Thin feces: The chicken digests normally, but the feces contain a lot of water and are not formed. It is mostly caused by a sudden increase in water intake during hot weather, too much salt in the feed, mild infection of E. coli, and slightly toxic substances in the feed.

Rusty watery stool: Rusty watery stool mixed with urate, and sometimes mixed with incompletely digested feed. This is caused by severe intestinal bleeding. It is often seen in diseases that cause gastrointestinal bleeding, such as early Newcastle disease poisoning. Milky stool: Milky white, watery, like milk poured on the ground, often seen in mucosal congestion and mild enteritis. White watery stool: Sticky, often sticky to the chicken's anus, often seen in pullorum.

White watery stool: The stool is watery and mixed with white urate particles. It is more common in chickens with no appetite, paralysis and uremia. This is caused by the absence of food in the digestive tract and the stool is urate.

5. Identification and prevention of common fish diseases?

Hello, there are many common fish diseases. Here are some common fish diseases and their identification and prevention methods:

1. White spot disease

Identification: Small white spots appear on the fish's body. In severe cases, the fish's body is covered with small white spots, the fish swims slowly, and has no appetite.

Prevention and control: White spot disease drugs can be used for treatment, or salt water can be added or the water temperature can be increased to improve water quality. At the same time, feed nutrition can be strengthened to enhance fish resistance.

2. Fish mold disease

Identification: Grayish white or black fluffy substances appear on the fish's body, mucus secretion on the fish's surface increases, the fish swims slowly and has no appetite.

Prevention and control: Fish mold disease drugs can be used for treatment. At the same time, the water quality must be kept clean, excessive feeding and excessive density must be avoided, and feed nutrition must be increased.

3. Saprolegniasis

Identification: White or gray fluffy substances appear on the fish's body, mucus secretion on the fish's surface increases, the fish swims slowly and has no appetite.

Prevention and control: Saprolegniasis drugs can be used for treatment. At the same time, the water quality must be kept clean, excessive feeding and excessive density must be avoided, and feed nutrition must be increased.

4. Exophthalmos

Identification: The fish's eyes are bulging, the surface of the eyes is red, the fish swims slowly, and has no appetite.

Prevention and treatment: You can use drugs to treat exophthalmos. At the same time, ensure the water quality is clean, avoid excessive feeding and excessive density, and increase feed nutrition.

5. Fish rot

Identification: Ulcers appear on the fish's body, mucus secretion increases on the fish's surface, the fish swims slowly and has no appetite.

Prevention and control: Fish ulcer disease drugs can be used for treatment. At the same time, the water quality must be kept clean, excessive feeding and excessive density must be avoided, and feed nutrition must be increased.

The above is only a brief introduction to common fish diseases. Different fish diseases have different identification and prevention methods. It is recommended that fish farmers detect fish diseases in time during the breeding process and take correct prevention and control measures to ensure breeding benefits.

6. What disease causes chickens to have yellow-white or green feces?

Chickens have yellow, white and green feces. This is mainly caused by chicken E. coli. I hope my answer can help you.

7. What disease causes chickens to have yellowish and white feces?

Chicken diarrhea is yellow-white and thin. There are two kinds of diseases caused by it:

① Reticuloendotheliosis. It usually causes lesions in the digestive system, such as lesions in the intestines, gizzard and glandular stomach, with symptoms of indigestion and yellow feces, similar in color to feed.

② Enterotoxic syndrome. This disease is prone to occur after coccidiosis because the intestinal wall becomes inflammatory and thickened and the absorption function is reduced. Some sick chickens are infected with Eimeria, Escherichia coli or anaerobic bacteria and develop enteritis. The chickens have symptoms of malnutrition, such as poor growth, white combs and chicken feet, etc.

Treatment method: The brooding room must be thoroughly disinfected before the chicks are introduced. The chicken cages, feed troughs, sinks, and floors should be repeatedly rinsed and disinfected with hot alkaline water. At the same time, the chicken manure in the chicken farm should be cleaned up in time and treated pollution-free. The chicken house should be kept dry during daily breeding, and the chicken house should be disinfected at least 2 to 3 times a week, which can greatly improve the body's disease resistance. During daily feeding, the chickens should also be given a reasonable diet to ensure the normal nutritional needs of the chickens. Young chickens have a relatively high demand for vitamin K. Keeping the chicken house clean and sanitary and the chickens' nutrition balanced can effectively prevent the occurrence of chicken coccidiosis.

Warm reminder: When chickens become sick, they must be treated in a timely manner to avoid delaying the treatment time and causing unnecessary losses.

8. Rapid diagnosis and prevention technology of fish diseases?

There are many types of fish diseases. Generally, we first observe whether the fish has surface damage, such as body rot, skin rot, gill rot, tail rot, bleeding, etc., and then use a microscope to check whether there are parasites. Then we further dissect the sick fish to observe whether there is enteritis, intestinal ascites, anal swelling, liver enlargement, liver rot, liver erosion, etc. Finally, we test the pond water quality indicators, conduct a comprehensive analysis, and conclude that if we can treat the disease, the chance of cure is still very high! But generally speaking, even if the farmed species can be cured, losses are inevitable. If the treatment is not timely or the right medicine is not given, a large number of deaths may occur, resulting in heavy losses!

Therefore, it is recommended that farmers do a good job of prevention in daily life, adjust the water, improve the bottom, disinfect and sterilize regularly, so as to reduce the chance of disease in farmed animals.

9. How to identify and prevent sesame virus disease?

Identify the host:

①Sesame: mosaic leaves, wrinkled, bent stems, and shortened internodes. ;

②Cucumber: Local necrotic spots on the inoculated leaves and systemic chlorotic spots. ;

③Tomato: Systemic leaf curling and deformity. ; Serological detection: The virus purification preparation did not react with the antiserum of potato Y, turnip mosaic and watermelon mosaic viruses. ; Electron microscopic observation: In ultrathin sections, crystalline inclusions and windwheel-shaped (or scroll-shaped) inclusions were seen. The crystalline inclusions were dispersed in the cytoplasm and chloroplasts, while the scroll-shaped inclusions were only seen in the cytoplasm, and there were also a large number of aggregated virus particles. ; Quarantine risk assessment: The pathogen of this disease is sesame mosaic virus, which is non-persistently transmitted by aphids and seriously harms sesame. When Ji Liang conducted a risk assessment, the risk value was 8 points, which is a medium-risk pest. It has occurred in China, but because there is no artificial transmission route, it is a non-quarantine pest. ; Geographical distribution: China.

10. What are the symptoms and prevention of bean virus disease?

1. Symptoms

From the appearance, the plant becomes shorter, grows slowly, the new leaves are wrinkled and mosaic, and the growth is poor.

Bean virus disease often manifests systemic symptoms, and symptoms are obvious after the diseased plants emerge. Because there are many types of pathogens that cause this disease, mixed infections often occur in the field and produce different symptoms. After the plants are infected, the leaves will have clear veins, chlorotic bands, mottled or uneven green parts, wrinkled, twisted, and deformed leaves, plant growth will be inhibited, the plant will be short, flowering will be slow or flowers will fall, flowering and pods will be significantly reduced, the pods will be short, and sometimes green spots will appear.

2. Prevention and control methods

1. Establish disease-free seed fields, select disease-resistant varieties, carefully select seeds, and cultivate strong seedlings.

2. Use dry heat or hot medicine to treat seeds to inactivate the source of toxins and reduce the incidence of disease in the seedling stage.

3. Implement crop rotation, avoid repeated planting, strengthen fertilizer and water management, and increase the application of phosphorus and potassium fertilizers. Remove diseased plants and leaves in time to reduce the source of disease.

4. Take early treatment and continuously treat aphids to reduce the transmission of insect vectors. When aphids are found, spray imidacloprid and other pesticides in time, focusing on the back of the leaves.

5. Combined with spraying foliar nutrients, adding drugs that inhibit and inactivate the source of poison is more effective than using warming drugs alone. In the early stage of the disease, spray 0.1%~0.2% potassium dihydrogen phosphate + urea + ordinary laundry soap (or black soap) in equal amounts for 3~5 times, once every 7~15 days, with dense planting at the beginning and sparse planting at the end, which helps promote plant growth and control the spread of the disease.

6. At the early stage of the disease, spray 1000 times diluted 1.5% alkanol copper sulfate emulsion, or 100 times diluted 10% mixed fatty acid aqueous solution, or 500-700 times diluted 20% morphine copper acetate wettable powder, once every 7-8 days, and spray 3-4 times in a row.
