What are the prevention and treatment methods for common chicken diseases?

Chickens are one of the most common types of poultry, and have a very long history of being raised in our country. To raise chickens well, it is essential to understand the disease characteristics of chickens and their prevention and treatment methods. Otherwise, once chickens become ill, the mortality rate is relatively high. Without mastering the techniques for diagnosing and preventing diseases in chicken farming, it is very difficult to raise chickens well. So what common diseases do chickens have? Let's take a look together with Qinnong Web.

1. Newcastle disease

Newcastle disease is an acute viral infectious disease. It has no epidemic season and can occur in all four seasons. It is extremely contagious, with a high incidence rate, rapid onset, and an extremely high mortality rate. When the disease occurs, the specific manifestations are difficulty breathing and diarrhea in chickens. If the case is acute, death occurs within a few minutes to a few hours after onset. If it is subacute, the chickens first become listless, have reduced appetite, ruffled feathers, drowsiness, difficulty moving, and make a gurgling sound from their mouths, and finally die.

Prevention and treatment methods: Because the onset of this disease is extremely rapid, prevention is generally the main approach. Chicks should be vaccinated in a timely manner, and routine feeding should be strengthened, with attention paid to hygiene and disinfection. After onset, drug treatment should be carried out promptly. A large-dose spray of Newcastle disease strain I vaccine can be used, which can effectively prevent and treat the disease.

2. Fowl cholera

Fowl cholera is an infectious disease commonly occurring among poultry. This disease mainly occurs during long periods of rainy weather and is transmitted through the digestive tract and respiratory tract. The specific manifestations of onset are septicemia and diarrhea. Like Newcastle disease, it is divided into acute and chronic forms. The acute form has a rapid onset and an extremely high mortality rate, while the chronic form manifests as joint inflammation and swelling, depression, ruffled feathers, difficulty breathing, diarrhea, and grayish-yellow, white, and green droppings.

Prevention and treatment methods: The harm of this disease is extremely great, and there is no good treatment method. Prevention should be the main approach, with timely vaccination for prevention. After onset, drugs can be used for the chronic form. If it is acute, the sick chickens must be disposed of promptly. If an outbreak occurs on a chicken farm, there is basically no cure. The chicken farm must be completely locked down, all chickens on the farm must be culled and burned, and then the site must be fully disinfected. After two months, new chickens can be introduced for raising again.

3. Colibacillosis

Colibacillosis is a common disease caused by E. coli bacteria. It does not specifically represent a certain disease, but is a general term for diseases caused by E. coli. When the disease occurs, it manifests as diarrhea, depression, poor appetite or no eating, and often also damages the liver of chickens and causes death.

Prevention and treatment methods: First, reduce stocking density, do a good job in sanitation and disinfection, and ensure that drinking water and feed are clean and hygienic, preventing the occurrence of this disease due to spoiled or moldy drinking water and feed. When the disease occurs, the specific drug Jianggan Yisha can be used for prevention and treatment, and vitamins can also be added to the feed to enhance disease resistance.

4. Pullorum disease

Pullorum disease is caused by Salmonella and mainly occurs in chicks one month old. Chicks have weaker constitutions and are susceptible to it. The specific manifestations of onset are not eating, listlessness, dehydration, diarrhea, and ultimately death.

Prevention and treatment methods: Usually strengthen feeding, disinfection, and isolation, maintain an appropriate temperature, and add an appropriate amount of antibiotics to the feed or drinking water. After onset, isolate the sick chickens promptly, then use enrofloxacin or florfenicol in drinking water for treatment.
