How to prevent and treat staphylococcosis in farmed pheasants?

1. Clinical symptoms: The sick pheasants are listless, eat less, and have ruffled feathers. Some sick pheasants have swollen joints, especially the metatarsal and toe joints, which are painful when squeezed, making standing and walking difficult, with lameness. Some sick pheasants have diarrhea and pass yellow-green watery droppings.

2. Necropsy changes: Necropsy shows subcutaneous congestion in the chest and abdomen, appearing as diffuse purplish red; the liver is slightly swollen and pale purplish red. The joints are swollen, congested, or hemorrhagic, and the joint capsules contain relatively large amounts of serous exudate, pus, and caseous material. 3. Laboratory diagnosis: Take the subcutaneous edema fluid from the affected area, stain and examine under a microscope, and paired Gram-positive cocci can be seen. Bacterial culture shows colonies that are moist, smooth, round, and raised yellow colonies. The diagnosis is staphylococcosis in chickens. 4. Prevention and treatment measures: Isolate and raise the sick pheasants; debaek in time to prevent pecking among the flock, add 1% Zhuoyuling (No. 2) to the feed to treat feather-pecking vice, keep the flock environment clean and hygienic, and regularly disinfect alternately with Baidusha and Penwulingdan at a 1:600 concentration to eliminate pathogenic bacteria; for sick pheasants, inject gentamicin intramuscularly at 5000 units per 7.5 kg body weight, twice daily for 4-5 consecutive days, mix 0.1% chloramphenicol original powder into the feed for 5 consecutive days, and use 0.5% chloramphenicol original powder for prevention in healthy flocks. Improving environmental conditions, strengthening feeding management, and treating with sensitive antibacterial drugs can achieve satisfactory results.
