Continuous spreading of avian influenza around the world poses threat to poultry industry. But proper biosecurity measure is one of the ways to prevent infection and outbreak to the flocks.
The viruses are classified either a low pathogenic avian influenza, which causes very minimal to no signs of sickness to infected birds. Highly pathogenic avian influenza on the other hand, poses death to birds and threat to the local poultry.
A post by The Herald-Tribune classifies highly pathogenic signs and ways to biosecurity:
Highly pathogenic infected birds show signs of:
- Sudden death without clinical signs
- Lack of energy and appetite
- Swelling of the head, eyelids, comb, wattles and hocks
- Purple discoloration of the wattles, combs and legs
Recommended ways of biosecurity are:
- Have a biosecurity plan and adhere to it.
- Restrict access to the flock by people, pets, wildlife and rodents.
- Do not use pond or stream water to provide drinking water for birds unless the water is treated.
- Do not keep feed where wild birds can access it.
- Keep poultry pens and housing clean.
- Keep feed bins covered and stored in a location that is not accessible to wildlife, birds and rodents.
- Do not share birds or equipment with neighbors.
- Keep new birds separate from the flock for 30 days to verify they are healthy.
- Know the warning signs of infectious diseases.
- Do not take infected birds to market or exhibitions or fairs.
