Cause of the disease:

The site is wet and the duck house is not ventilated. Especially in rearing, it is easy to cause soft leg disease of laying ducks due to lack of sunlight, lack of exercise, excessive group density, inadequate dietary nutrition, lack of minerals, especially calcium, phosphorus, vitamin D and so on.

Symptoms:

Sick ducks, weak legs, once overturned, it is difficult to stand, often use two wings to support the ground to walk slowly, some joints swollen, emaciated day by day. After suffering from soft leg disease, ducks are prone to secondary colds and bronchitis, resulting in a great increase in mortality.

Prevention and control measures:

1. Clean the duck house in time: (1) often clean the duck house to keep it clean to prevent the spread of pathogens; graze properly, bask in the sun more, let ducks exercise more, try to make ducks gather less, avoid excessive density and crowd each other. (2) keep the duck house dry and ventilated, change the cushion frequently and prevent the duck house from dampness.

two。 Timely adjustment of feed: (1) Duck soft leg disease is sometimes caused by feed in special weather. Due to changing to compound feed in time, it is not advisable to feed with self-made undernourished feed or single rice. (2) increase the feeding of vitamin D, calcium, phosphorus, green feed, wheat bran, fresh corn, rice bran accounted for 810% of the diet, calcium accounted for 1.5%. (3) adding calcium mineral additives to duck feed and feeding cod liver oil if possible.

3. Timely early prevention and treatment: the treatment of duck soft leg disease must be started as soon as possible. At the initial stage of the disease, we should pay close attention to the treatment, otherwise the treatment effect is poor and the mortality rate is high. In the early stage of the disease, ducks were treated with drugs such as vitamin D and colloidal calcium by intramuscular injection in time, each duck was given 500 units of vitamin D and 0.5 ml of colloidal calcium, and adult ducks were injected with 1 ml of vitamin D and 0.5 ml of colloidal calcium once a day for 3 consecutive times. At the same time, adult ducks were fed with calcium sugar tablets containing 0.5 grams of calcium phosphate and 15 mg of vitamin B (about 2 tablets). Adult ducks were given 3 times a day. If the duck toe blood vessels can be punctured while oral cod liver oil, the therapeutic effect is better.

4. Timely treatment of secondary disease: ducks with soft leg disease are often accompanied by secondary disease in the middle and later stages, so secondary diseases such as duck cold and bronchitis should be treated while treating duck soft leg disease.

Note:

After some duck farmers encounter ducks suffering from soft leg disease, they often increase calcium, thinking that it is caused by calcium deficiency. In fact, the prevention and treatment of duck soft leg disease can not add too much calcium in the feed, according to the requirements, no more than 3%, otherwise it is easy to cause poisoning and greater losses.
