E. coli salpingitis in egg laying hens

Salpingitis caused by E. coli is a major cause of reduced productivity, increased mortality and risk for vertical transmission of E. coli in egg-laying hens.

Chronic salpingitis – what are the consequenses?
The fate of infection is dependant on both the hen itself and the strain of E. coli casing the infection. Hens that survive the acute infection may either cure the infection, cure the infection but stop laying eggs, develop a chronic salpingitis but continue egg production or develop a chronic infection but stop laying eggs.

The aim of the project is to investigate how many hens that develop a chronic infection after being acutely infected using an ascending infection model. Furthermore the impact on the egg production will be investigated.

The project will be carried out during 2017 and is funded by "Fjerkræafgiftsfonden" (”Æggelederbughindebetændelses betydning for pro-duktivitet”)

Effect of vaccination against E. coli in layers
The use of commercially available vaccines against respiratory E. coli infections are becoming more and more popular in the prevention of E. coli salpingitis in layers despite very little documentation on the efficacy for this indication of use.

The aim of the project is to investigate the effect of these vaccines in high producing layers using ascending infections.

The project will be carried out during 2017 and is funded by "Fjerkræafgiftsfonden" (”Effekt af Poulvac Vaccination i konsumægs-produktion”)

Effect of vaccination against E. coli in broiler breeders
The use of commercially available vaccines against respiratory E. coli infections together with autogenous vaccines has become a widely used practice in broiler breeders to ensure both a high quality offspring but also to reduce the occurrence of salpingitis in the broiler breeders.

The aim of the project is to optimize the vaccination strategies for broiler parents and broilers. The project will be carried out during 2017 and is funded by "Fjerkræafgiftsfonden" (”Optimeret E. coli vaccination af slagtekyllingeforældre”)
