Vaccination is a method were a weak form of a disease is introduced to create or activate immunity within the flock. It is a proactive approach of disease prevention. It is however important to note that vaccinations can only be done on healthy birds and in an event that a vaccination is due but birds are unwell farmers are encouraged to treat the birds first and vaccinate once the health status of the flock is improved.
1) Individual vaccinations -
These can either be injections or eye drop vaccinations and are very much labour intensive. These are mainly done at the hatchery.
2)Drinking water vaccinations-
these are mainly done both in rearing and when also birds are in lay. These are used to administer vaccines like Newcastle (ND) vaccines as well as Gumboro (IBD) vaccines. The vaccines has to be consumed within a period of 2 hours. To ensure the birds consume the water timely water has to be withdrawn from the birds for a period between 1-2 hours prior to vaccination depending with season i.e, more time for winter season. A chlorine stabilizer can be added to the water.
3) Spray vaccinations-
these are common at the hatchery when chicks are day old as well as in rearing and egg production. It is on of the easiest methods of vaccinating and a sprayer producing the finest droplets has to be used for effective vaccine distribution.
A Brife discripition of how vaccines function in poultry
vaccines work by stimulating an immune response in a bird with out causing the disease its self.
If a healthy bird is vaccinated,the bird's own immune system will respond to the vaccine by activating an army of cells designed to attack and destroy the invenders before they cause damage to the bird.
After the attack several specialized immune system cells remain,called memory cells.these memory cells will remember the infectious agent to which the bird is vaccinated.
If later in life and encounter with the infectious agent takes place,the bird,s immune system is capable of a quick "detect and destroy" of the infectious agent resulting in a protections from the disease and therefore preserving the productive health of the flock.
When the body produces the cells to protect it against infectious agent we need to give a favourable environment by strengthening the biosecurity using strong disinfect viruchock
Then after vaccination support the cell with good immune boosters sangrovit for 5 days
