How can lice be removed from broilers? - briefly
Effective control requires cleaning and disinfecting housing, applying an approved insecticidal spray or dust according to veterinary guidance, and conducting regular inspections. Follow recommended withdrawal periods to guarantee meat safety.
How can lice be removed from broilers? - in detail
Lice infestations in broiler flocks cause skin irritation, reduced weight gain, and increased mortality. Early detection relies on visual inspection of feathers, skin, and droppings for live insects, nits, or lesions. Effective eradication combines chemical, biological, and management strategies.
-
Chemical control: Apply approved insecticidal sprays or pour‑ons (e.g., pyrethroids, organophosphates) according to label dosage and withdrawal periods. Rotate active ingredients to prevent resistance. Ensure thorough coverage of the entire bird surface and the litter layer.
-
Biological agents: Introduce entomopathogenic fungi (Metarhizium anisopliae) or nematodes that infect lice larvae. Use formulations validated for poultry environments and follow recommended application rates.
-
Environmental sanitation: Remove and replace litter weekly; disinfect housing with high‑temperature steam or approved disinfectants. Seal cracks and gaps to limit re‑infestation from wild birds or rodents.
-
Mechanical removal: Conduct regular dust‑bathing sessions with fine sand or wood ash to dislodge parasites. Use water‑based misting systems to wash birds, followed by drying to prevent secondary infections.
-
Biosecurity measures: Restrict entry of personnel and equipment; require footbaths and clothing changes. Quarantine new stock for at least two weeks and treat prophylactically before integration.
-
Monitoring and record‑keeping: Perform weekly counts of lice per bird using a standardized sampling method. Document treatment dates, products used, and observed efficacy to adjust protocols promptly.
Combining these interventions reduces lice populations, improves flock health, and minimizes economic losses. Continuous assessment and adherence to veterinary guidance ensure sustainable control.
