Salmonella Vaccine For Backyard Chickens

Most vaccinations are made for commercial units and are in doses of 1000 birds or above. Even so, these are still relatively cheap and any extra doses can be discarded. For most backyard flocks, vaccination is unnecessary unless you encounter a particular disease problem within your chickens or you are frequently buying and selling hens. No vaccine is 100% effective, but they can help to control disease. If you are buying new birds, check what they have been vaccinated against, many excommercial hens will have already had some vaccinations. Most vaccinations are given at and around birth, vaccinating an older hen is less likely to be as effective as if they were vaccinated with a primary course when younger. Also poultry vaccinations are not thought to be so effective in outside birds. Many vaccinations will not cover and protect you bird for life so boosters may be needed; speak to your vet for advice

Description

Foodborne Salmonella causes more than 1 million illnesses a year in the United States and is showing no sign of declining. With chicken the most consumed meat in the U.S. and a significant source of these infections, strategies to reduce Salmonella contamination along the entire poultry production chain could reduce the impact of this disease.

No vaccines exist to fend off Salmonella infections in humans, but vaccination programs for chickens and turkeys—combined with other on-farm interventions—have helped significantly reduce contamination from some of the many varieties, or serotypes, that make people sick. This progress is encouraging. Poultry producers and retailers should build on these gains by supporting development of new vaccines and ensuring that these products are used. Despite progress in controlling some serotypes, infection rates for others have risen sharply over the past decade. Overall, Salmonella in food sickens Americans about as often today as it did 20 years ago.

Benefits of Salmonella Vaccine For Backyard Chickens

Vaccination as part of a Salmonella control program contributes to the achievement of Salmonella free poultry meat and eggs. Live and inactivated Salmonella vaccines are available.

Vaccination against Salmonella protects chickens from:

  • Infection or re-infection through vermin and the environment.
  • Infection from contaminated feed.
  • Spread of an undetected infection.
  • Spread of infection in the hatchery, mainly in the hatchers. The offspring of vaccinated birds are protected by maternal antibodies.
  • Spread of infection in a flock where a few chickens are not protected.

Features of Salmonella Vaccine For Backyard Chickens

In addition to the large number of serotypes, the genus Salmonella presents a large variability among the serotypes. Some are more adapted to the intestine and do not go beyond the gut, others can get into the blood stream and have the ability to colonize liver and spleen. Some survive longer in the environment, others do not. Most of the animal species can be infected with Salmonella, therefore cross infection is very common among birds.  

These and other general features of Salmonella make its control difficult. It requires a lot of knowledge and investments. We have to establish a program and not just a single procedure. Salmonellosis is not the most devastating poultry disease, but it is one of the most difficult diseases (agent) to control. The main reason is the large variety of serotypes and the very complex epidemiology of this microorganism. 

To explore alternatives to control Salmonella in poultry, we have to divide them into two groups: Typhoid and Paratyphoids. 

GroupSerotypes
Typhoid group Salmonella gallinarum Salmonella pullorum 
Paratyphoid group All other serotypes
