Duck viral hepatitis is a particular headache for the bosses, the disease is urgent, fast spread, high mortality, often causing major economic losses to the duck farm. Let's jump right into the topic!
The first is the clinical symptoms, how to determine whether it is duck hepatitis.
Sick ducks show mental atrophy, sagging wings, inactivity, neck reduction, eyes half closed, movement in a daze, often unable to keep up with the group, reduced feeding intake or hunger strike, and generalized convulsions occur in people who have been sick for more than half a day. Sick ducks lie on their sides and head to the back, known as "back neck disease", which is manifested by repeated pedaling of spasmodic feet, sometimes rotating on the ground, the duck beak and the tip of the duck claw are dark purple, and a few sick ducks die in front of the yellow-white or green thin feces, but some have no symptoms, and they die with one back neck and one leg.
So what is the route of transmission? How does duck hepatitis come about?
Most of the duck farms that have outbreaks of this disease are caused by the infection of sick ducks purchased from the epidemic area or the diseased duck farm, which is mainly transmitted through the digestive tract and respiratory tract, and the mobile circle of breeders and the visit of outfield personnel, and the acquisition of sick and residual duck personnel may become the main way to spread the disease. Repeated use of vehicles, utensils and bedding without disinfection, and littering of sick and dead ducks in the field are also important ways of transmission of the disease.
Duck viral hepatitis has happened! What to do! Don't worry! Look down!
1. It is strictly forbidden to purchase young ducks from diseased duck farms and hatcheries, and it is strictly forbidden for off-site personnel to enter the duck farm or channeling circle without disinfection.
2. The door of the brooding room should be equipped with a disinfection pool. Sick and dead ducks are treated in strict accordance with hygiene and disinfection requirements. Strengthen the management of breeding, establish a strict sanitation and disinfection system and strictly implement it to ensure the hygiene and cleanliness of the feeding environment.
3. Duck farms should improve the awareness of epidemic prevention, strictly carry out specific prevention, and young ducks should be actively immunized at 1 day old. Once the disease occurs in ducklings, yolk antibodies should be injected quickly or other effective measures should be taken to control the epidemic of the disease and reduce mortality.
4. Strengthen disinfection Strict disinfection is an important measure to prevent and control the disease, using 2% to 9% of the fire alkali solution to disinfect the walls of the duck house and the surrounding environment, 1 to 2 times a week. Duck disinfection can be disinfected with 0.3% peracetic acid or chlorine preparation disinfectant.
Everything is predetermined! Use the cost of treatment as a worry-free, cost-saving, time-saving treatment!
It is recommended to use Longchang bile acid from the age of one day in the chicks. Bile acids, the main active ingredient in bile! The addition of exogenous bile acids can make up for the lack of bile in a short period of time and reduce the burden on the liver! As a kind of excretory fluid, it can effectively decompose endotoxins, promote liver cells to secrete a large amount of thin bile, make the biliary tract unblocked, eliminate bile stasis, and play a choleretic role. Many toxins, heavy metals, mycotoxins and other harmful substances are also excreted from the bile, thereby reducing the accumulation of toxins in the liver, which can strengthen liver function and solve the problem of duck hepatitis.
