Caller X: Hello Senceagric
Happy Farmer: Hi, good afternoon Mr. X

The aim of vaccination schedule for laying birds is;
This is a specific vaccination program for any laying bird. The program varies depending on the endemic diseases prevalent at a particular production site, farm or area.
TYPES OF VACCINES
Vaccines comes in “activated” and “inactivated” forms. Both forms of vaccines should be used in the proper way and timing in order to achieve the goal of providing immunity for the birds.
Vaccination failure can be as a result of many interrelated factors such as
