Prevention and treatment of diarrhea in the later stage of Muscovy Duck Culture

At present, duck farming in China has gradually changed from small-scale rural household sideline to large-scale commercial production. At the same time, the occurrence regularity of duck disease has changed greatly due to the change of feeding mode. In view of the prevention and treatment of diarrhea in the later stage of duck, the author now puts forward several suggestions for reference.

Diarrhea caused by the environment in summer, due to the increase of duck drinking water in high temperature weather, the reduction of intestinal flora, the stress of overcast and rainy lightning, excessive feeding density, poor ventilation, poor heat prevention and cooling, and excessive indoor ammonia smell can cause duck diarrhea in summer. therefore, it is necessary to do a good job in the feeding and management of ducks in high temperature weather, timely removal of feces, replacement of bedding materials, and supply of fresh and clean drinking water. At the same time, cod liver oil and vitamin C should be added to its feed to reduce stress.

Diarrhea caused by bacterial diseases include colibacillosis, serositis, Clostridium welchii and so on. Ampicillin, cefradine and ciprofloxacin can be used to treat colibacillosis and white dysentery; rifampicin, sulfadimethoxine, florfenicol and other drugs can be used to treat serositis and clostridium welchii; we should start with prevention of viral diseases such as duck influenza and paramyxovirus, vaccinate against avian influenza at 7 days and Newcastle disease at 14 days.

Diarrhea caused by feed improper preservation of feed is easy to cause mildew, and diarrhea will occur when ducks eat moldy feed. Can be added to the feed anti-mildew agent (SuMeiJian, etc.) for prevention; too high protein in the feed will increase the burden on the duck kidney, cause metabolic disorder, diarrhea, treatment must be timely kidney; improper proportion of calcium and phosphorus and vitamin deficiency will also cause duck diarrhea, so the feed formula should be adjusted in time.

Excessive multi-dimensional dosage of drug-induced diarrhea will cause duck diarrhea, which should be adjusted in time; for diarrhea caused by drug poisoning, it is necessary to protect the liver and kidney (Shen Ganbao), dredge kidney and diuresis; for diarrhea caused by continuous medication, intestinal flora should be adjusted, Bacillus and probiotics (Sumeijian) should be added, and antibiotics should be used to prevent secondary infection. In the process of drug use, it is necessary to change from low sensitivity to high sensitivity, from single drug use to compound preparation, to formulate reasonable drug use procedures, and to select veterinary drugs produced by reputable manufacturers.
