Zusammenfassung:Campylobacter is one of the leading causes of bacterial human acute gastroenteritis. These microorganisms are highly prevalent in poultry semen and may contribute to vertical transmission of the pathogen between the breeder hen and offspring. Unfortunately, strategies to reduce or eliminate these pathogens in poultry semen negatively impact sperm viability. Many plant essential oils have been reported to exhibit antimicrobial activity against bacteria, fungi and viruses. The objective of this study was to examine the efficacy of trans-cinnamaldehyde, the main component in cinnamon oil, to reduce Campylobacter concentrations in chicken semen. Semen was collected from roosters, pooled and diluted with semen extender, then divided into treatments: negative control, positive control or treatments containing concentrations of 0.24%, 0.12%, 0.06%, 0.03% or 0.015% trans-cinnamaldehyde. Sperm viability remained at 80% or above for all treatment groups. Trans-cinnamaldehyde reduced Campylobacter in semen, without detrimentally affecting sperm viability and might provide a practical solution to eliminate Campylobacter in poultry semen after in vitro storage.
