Respiratory Disease and Immune Status

02 July 2015
Diamond V

US - Recent university research evaluated the effects of Original XPC (XPC) on antibody titers and clinical signs of respiratory disease in poultry, Dr Stephanie Frankenbach reported in the Diamond V newsletter PoultryAdvisor.

Previous research had shown that Diamond V technologies provided support for the immune system, particularly in its response to respiratory challenges.

Newcastle Disease Virus: The effects of feeding XPC to broilers vaccinated with Newcastle disease virus (NDV) has been reported in published broiler studies since 2007.

Researchers at Texas A&M University recently evaluated feeding XPC to broiler chicks vaccinated at one day of age with B1 NDV vaccine, followed by B1, Lasota NDV vaccine at 21 days of age.

Blood and tissue samples were taken to evaluate the birds’ immune-competence through flow cytometry and gene expression.

Findings were presented at the International Poultry Scientific Forum (IPSF) 2015 in Atlanta, USA and discussed in PoultryAdvisor.

Infectious Bronchitis Virus: Observations from two separate trials conducted at Auburn University College of Veterinary Medicine Researchers studied the effects of Infectious Bronchitis Virus (IBV) challenge (Trial 1) and IBV vaccine + IBV challenge (Trial 2) in XPC-fed broilers. Results were presented at IPSF 2015 and discussed in PoultryAdvisor:

Infectious Laryngotracheitis: Researchers evaluated the effects of XPC-fed broilers in three separate trials -- LT vaccinated (in ovo), ILT challenged; Vaccinated, ILT-challenged; and Non-vaccinated, ILT-challenged.
