Prevention and cure measures for the ulceration of the sole of cherry grain duck

First, the incidence and main symptoms

More than 4,000 cherry bred ducks imported from certain duck farms in Dongping County, Shandong Province, were found to be difficult to walk after being raised to 28 days of age. On examination, it was found that the foot of some species of ducks began to rot and bleed. Of the 3800 ducks examined, 289 were ulcerated and abscessed on the soles of the feet and 96 were unable to walk. All ducks that cannot walk can only flap their wings to move forward when they drive, and they have lost their ability to eat and drink freely. Some ducks have swollen and inflamed joints.

Second, the cause analysis

1. Gain special weight. Ducks have been fed with ducks with higher nutritional levels since entry into the farm and feed intake has not been controlled. Therefore, this batch of ducks grew very fast, and the individual average weight reached 1.5 kg by the age of 4 weeks, which exceeded the standard body weight of 400 g (according to the British Cherry Valley Duck Breeding Standard).

2. There is a large amount of activity on the concrete floor, injuring the soles of the feet. As a result of frequent overstocking by keepers, some ducks stepped on sharp objects and injured.

3. Bacterial infection. As some types of duck feet have not been treated in time after the injury of the stratum corneum, causing inflammation, swelling, suppuration and ulceration, a small number of duck ankle joints are also infected by bacteria and become inflamed and swollen.

Third, prevention and control measures

1. Isolation of sick ducks. After inspection, only those ducks whose foot soles festered were concentrated and raised on the grass, and the festered surface was cleaned with hydrogen peroxide, and then rubbed with iodine. In addition to the above treatment for a small number of able to walk sick ducks, they should also be inflamed and fed with sulfonamides. Drugs and so on. Single-cage rearing, abscess disease ducks must be surgical incision abscess, remove pus, remove necrotic tissue, wash with 3% boric acid solution, and then coated with ishige ointment, while taking anti-inflammatory drugs.

2. Clear the sharp stones on the event site to reduce the amount of activity of the ducks and slowly drive the ducks out of the duck house.

3. Appropriate food control, slowing the rate of weight gain. Appropriately control the amount of food for ducks, and according to the standard of day-age allocation of the corresponding nutritional level of feed.

4. Eliminating seriously ill ducks. For diseased ducks that can't walk, and the soles of the soles of the feet are ulcerated and the joints are severely inflammatory and enlarged, they are eliminated.
