Week 36: Vitamin C Reduced Damage Caused by Infectious Bronchitis
A new study found that chickens given additional vitamin C had less tissue damage after being infected with infectious bronchitis. Although the results are promising, they do not mean that vitamin C cures the disease or that high doses should be given without veterinary advice.
How was the study conducted?
Researchers carried out a controlled study using specific pathogen-free chickens. For 21 days, the chickens were fed either a diet without additional vitamin C or a diet containing 400 mg of vitamin C per kilogram of feed. They were then infected with infectious bronchitis virus, also known as IBV.
What did the study find?
When examined under a microscope, the chickens that received additional vitamin C had less tissue damage. Vitamin C also appeared to influence how their immune systems responded to the virus.
How reliable are the results?
The study provides some evidence that vitamin C may help the body cope with the infection. However, it was a short study involving specific pathogen-free chickens, and only one dose was tested. We therefore do not know whether the same effects would occur in older chickens, laying hens, or naturally infected backyard chickens.
What does this mean for backyard flocks?
The results do not mean that vitamin C cures infectious bronchitis or that chickens should be given high doses without veterinary guidance. A complete diet, supportive care, and veterinary advice remain essential when dealing with respiratory illness. However, the findings may be valuable for future research into supportive care for sick chickens.
