Introduction

• Biosecurity is a practice designed to prevent the spread of disease onto your farm.
• It is accomplished by maintaining the facility in such a way that there is minimal traffic of biological organisms (viruses, bacteria, rodents, etc.) across its borders.
• Biosecurity is the cheapest, most effective means of disease control available.

Basic Principle of biosecurity

a) Isolation refers to the confinement of animals within a controlled environment. A fence keeps your birds in, but it also keeps other animals out. Isolation also applies to the practice of separating birds by age group. In large poultry operations, all-in/all-out management styles allow simultaneous depopulation of facilities between flocks and allow time for periodic clean-up and disinfection to break the cycle of disease.

b) Traffic Control includes both the traffic onto your farm and the traffic patterns within the farm.

c) Sanitation addresses the disinfection of materials, people and equipment entering the farm and the cleanliness of the personnel on the farm.

d) Vaccination is a regular process of administration of live, dead or attenuated biological liquids inside the body on fixed date to prevent from various viral and bacterial diseases.
