Hello everyone, I am Teacher Fei who focuses on the cause of avian disease, escorting your breeding. Duck is a common waterfowl, which occupies a large number in China's breeding industry. Speaking of raising ducks, we have to talk about duck infectious serositis, which has a high incidence, a fast rate of infection, and a high mortality rate, which is one of the diseases that are the greatest threat to the duck industry, and it is also a "nail in the eye, a thorn in the meat" of duck farmers, today Teacher Fei will help you pull out this "eye nail, meat thorn", so that you can breed worry-free!

Infectious serositis in ducks is an expository, acute or chronic infectious disease caused by Lymerella lycopherolii, and in the statistics of many years, it has been found that the disease mainly affects ducklings aged 1-8 weeks. This disease is characterized by fibrous pericarditis, filassic air cystitis, which is an infectious disease that seriously harms ducklings.
<h1 class= "pgc-h-arrow-right" > epidemic characteristics and transmission routes</h1>
Infectious serositis in ducks is more common in ducks aged 7-40 days, and the smaller the day-old, the higher the mortality rate. The incidence of ducks over 7 weeks of age is very low, and adult ducks can carry bacteria without showing clinical symptoms. The disease can be diseased all year round, the incidence rate can reach 90%, the mortality rate is 5% to 75%, the disease is mainly infected by respiratory tract or skin wounds, it can also be transmitted vertically through eggs, feed contaminated by the virus, drinking water, air, etc. are important infectious routes, feeding density is too large, poor ventilation, humidity, malnutrition are the causes of the occurrence of the disease.
<h1 class="pgc-h-arrow-right" > clinical symptoms</h1>
The most acute disease of the duck can not see the symptoms of sudden death, acute duck clinical manifestations are depressed, decreased intake, serious do not eat or drink, lame turn over, convulsions, spasms, shaking head and head, some head and neck bending in a circle of about 90 °, feces thin green or yellow-green. As the course of the disease progresses, some of the sick ducks turn into zombie or residual ducks.
< h1 class= "pgc-h-arrow-right" > autopsy lesions</h1>
Autopsy of dead ducks revealed inflammation of the pericardium, hepatic epiderma, and air sac walls. The pericardium is covered with yellowish or caseous fibrous exudates, the pericardial effusion increases, the heart is surrounded by yellowish fibrous, the liver is earthy yellow or brownish red, the swelling is brittle, and the gallbladder is enlarged.
<h1 class = "pgc-h-arrow-right" > infectious serositis prevention</h1>
(1) Daily feeding management
Farms should strengthen daily feeding management, the implementation of the full in and all out system, do a good job in the ventilation of the house, to avoid excessive humidity in the house, to ensure the appropriate feeding density, regular disinfection of the house and the farm, commonly used with poultry disinfectant has povidone iodine and dilute glutaraldehyde, two alternate use, scientific feeding management is an effective measure to control and prevent the disease.
(2) Specific therapeutic/preventive drugs
At present, for the prevention of duck infectious serositis, in addition to paying attention to health management, there are two kinds of vaccines and drugs, the use of vaccines at the same time, you can add preventive drugs in diet or drinking water, if you use drugs with high prices, the effect is not good, you can understand the specific drugs recommended by Teacher Fan below.
<h1 class= "pgc-h-arrow-right" > special drug "general" for infectious serositis, no resistance! </h1>
(1) The specific strain of Clostridium butyrate is preferably made by compounding traditional Chinese medicine extracts such as houttuynia cordata as a carrier
(2) Easy to absorb, good palatability, rapid absorption.
(3) No anti-drug: no drug residue, no drug resistance; long duration of drug effect: no recurrence, no rebound, better treatment effect.
