Title: Management methods to prevent disease


1
Management methods to prevent disease
  • There are two kinds of diseases
  • Infectious
  • Noninfectious
  • But.All diseases are caused by management

David A Halvorson, DVM
2
Management methods to prevent disease in the
poultry industry
  • Reduce or eliminate egg transmission
  • Immunization
  • Medication
  • Biosecurity

3
1. Reduce or eliminate egg transmission from
parents
  • National Poultry Improvement Plan (NPIP)
  • The plan
  • Participants
  • Specific diseases
  • Hatching egg handling
  • nest management
  • gathering
  • sanitation

4
2. Immunization
  • Selection of vaccines
  • Programming vaccines
  • Storage and handling of vaccines
  • Application of vaccines

5
3. Medication
  • Preventive medication
  • None routinely used in table egg production
  • Coccidiostats and drugs to control enteric
    pathogens
  • Treatment
  • Only approved drugs
  • No prescription drugs in egg layers
  • Prescription drugs can be used in meat birds
  • Route of administration water or feed

6
4. What is biosecurity?
  • The use of management techniques to prevent
    disease
  • Sanitation
  • Isolation
  • Traffic control
  • Universally preached but widely misunderstood by
    industry people, regulatory officials,
    academicians, etc.

7
Biosecurity
  • Why go to all this work to keep diseases out?
  • Animal Health
  • Humane Care
  • Economic Performance
  • Public Health

8
How are diseases introduced?
  • people
  • poultry
  • facilities and equipment
  • vectors
  • vaccines

9
Biosecurity
  • What are the characteristics of the diseases
    were trying to keep out?
  • What are the essentials of biosecurity?
  • Why does biosecurity fail?

10
Examples of the diseases that can be kept out by
biosecurity
  • Mycoplasma
  • Mites and lice
  • Infectious coryza
  • Avian influenza
  • Others some Salmonella, Pasteurella, etc.

What are their characteristics?
11
What are the essentials of biosecurity?
  • The concept
  • The structure
  • The operation

Simon Shane
12
Conceptual biosecurity
  • The concept that diseases are preventable is the
    foundation of biosecurity!
  • The location of the farms and houses
  • Geographic separation
  • Type of housing

13
Structural biosecurity
  • How we set up the structure
  • Layout of the farm
  • Location of roads, drainage, fences etc.
  • Construction
  • Biosecurity buildings

14
Operational biosecurity
What we do day to day
  • Role of employees in keeping diseases out
  • Policies, Procedures and Practices
  • Bird moving
  • people entry policies and procedures
  • supplies and equipment entry policies and
    procedures
  • everyday practices that affect health and
    performance
  • Monitoring of health status and immunity
  • Continuous review by all employees

Biosecurity
  • Conceptual
  • Basis or foundation for what we do
  • Structural
  • How all aspects of the farm are constructed
  • Operational
  • What we do day to day

21
Why does biosecurity fail?
  • Poor biosecurity concept
  • Bean counter mentality
  • Lack of management understanding
  • Poor structure
  • Example facilities not bird proof
  • Poor operation
  • Misunderstandings
  • Noncompliance
  • Inability to comply

22
Summary
  • The layer industry has 4 ways to prevent disease.
  • prevent vertical transmission major effort
  • medication little used
  • vaccination widely practiced
  • biosecurity very important
