Another major source of pathogens gaining entry into the farm, other than newly introduced animals and people is through vehicles. The following precautions need to be taken for vehicle regulation:

a. No vehicles are generally allowed entry into the quarantine.

b. Entry may be allowed only if sanctioned by the unit head.

c. There should be facilities for unloading feed, fodder or animals at the periphery of the quarantine without entry into it.

d. Vehicles entering the quarantine should be clean and free of visible manure on tires and wheel wells.

e. Vehicles should pass through tyre dips of minimum 5.5 m length, 3.5 m width and maximum depth of 6-9 inches at the centre.

f. Cleaning & disinfection of vehicles to be done.

▪️The length of quarantine required

– This must cover incubation periods of most acute infectious diseases, so may be 6 weeks or longer, or the time for test results to be received.

- Import permits for imported animals – check with the veterinary authority.

- Release of animals from quarantine – formal notices may be required.

➡️The length of isolation

This should extend till recovery or death of sick animals or birds and also for a short period after recovery.

➡️Use vaccines

Vaccines are commonly used to protect cattle against respiratory disease and abortion. For herd additions, these vaccines may be given during the quarantine period to activate animals or birds immunity.
