Title: A Poultry Health Update


1
A Poultry Health Update
  • Presented By
  • Adam Hady
  • Agriculture Agent
  • Richland County UWEX
  • 11/06

2
Topics of the Presentation
  • Avian Influenza
  • Mites and Lice
  • Respiratory Diseases
  • Establishing a Biosecurity plan

3
Avian Influenza
  • What is it?
  • Why are we so concerned?

4
Low Path AI
  • Mild or no clinical signs in poultry
  • Decreased egg production
  • Mild respiratory signs cough, sneeze
  • Feces, ocular, oral and nasal secretions
  • Bird-to-bird or contaminated equipment
  • Diagnosis
  • Virus isolation
  • Serology

5
High Path AI
  • Sudden death without clinical signs

6
High Path AI
  • Decreased activity and decreased feed consumption

Other Health Concerns
  • Mites Lice

15
Mites Lice
  • Mites
  • Size 1 millimeter in diameter
  • Color Dark Reddish Black
  • Egg Color Location
  • White to off-white along the feather shaft
  • Mites live on the host and in the environment

16
Mites Lice
  • Lice
  • Size 2-3 millimeters long
  • Color Light Brown
  • Egg Color Location
  • White and at the base of the feather
  • Lice only live on the host, and appear to be fast
    moving.

17
Mites Lice
  • Symptoms
  • Decreased Food Intake
  • Decreased Egg Production
  • Decreased Weight Gain
  • Increased Susceptibility to Other Diseases
  • If any of these symptoms are observed a visual
    inspection around the vent for lice or mites is
    recommended.

18
Mites Lice
  • Treatment
  • Sanitation and cleanliness are keys to control
  • Chemical control
  • Dust bath with Sevin
  • Pyrethrin-Based spray
  • Ivermectin medication

19
Respiratory Diseases
  • These are some of the most common diseases of
    poultry.
  • They cause a wide variety of impact on the flock,
    from production loss to mortality.

20
Respiratory Diseases
  • There are many causes and is very common
  • Signs
  • Coughing
  • Sneezing
  • Discharge from the eyes and nostrils

21
Respiratory Diseases
  • Causes
  • Viruses
  • Bacteria
  • Parasites (such as the gapeworm)
  • High ammonia levels

22
Respiratory Diseases
  • Vectors
  • Other Chickens
  • Rodents
  • Manure
  • Dust

23
Backyard Biosecurity
  • What is Biosecurity
  • Measures that are taken to prevent the transfer
    of diseases from place to place and animal to
    animal.

24
Six Steps To Biosecurity
  • 1. Keep Your Distance
  • 2. Keep It Clean
  • 3. Dont Haul Disease Home
  • 4. Dont Borrow Disease
  • 5. Be Informed
  • 6. Report Sick Birds

25
Biosecurity Plan
  • What is it?
  • A biosecurtiy plan is written document that
    outline procedures for preventing and handling
    diseases.
  • Are they practical for me?
  • Yes, no matter what your size of operation it is
    worth taking time to look at how to minimize
    disease threats.

26
Building a Biosecurity Plan
  • The first step
  • What am I currently doing?
  • Housing
  • Feeders and Waterers- how are they located?
  • What kinds of birds are commingled?
  • What age groups of birds do I have?
  • What are my feed sources?
  • How do I bring new birds into the flock?
  • How do I handle dead birds?
  • Etc.

27
Building a Biosecurity Plan
  • Step Number Two
  • Identify the areas where diseases could be
    introduced
  • Identify areas where cross contamination could
    occur.

28
Building a Bio Security Plan
  • Step Number Three
  • Outline ways that you could prevent
    contamination from your list in step 2
  • Step Number 4
  • Follow your Plan
