Wpływ olejków eterycznych na skład mikroflory jelitowej kurcząt brojlerów
Michalina Adaszyńska-Skwirzyńska

W związku z wprowadzeniem od 1 stycznia 2006 r. w krajach Unii Europejskiej całkowitego zakazu stosowania antybiotykowych stymulatorów wzrostu w żywieniu kurcząt brojlerów, naturalną alternatywą antybiotyków stały się fitobiotki. Olejki eteryczne zaliczane są do grupy substancji czynnych, które mogą pełnić u kurcząt funkcję chroniącą przed szkodliwym oddziaływaniem patogennych mikroorganizmów (Zeng i wsp., 2015). Należy podkreślić, że skład mikroflory jelitowej kurcząt jest czynnikiem wpływającym na zdrowotność ptaków, a tym samym opłacalność produkcji.

W związku z nasilającym się problemem lekooporności bakterii oraz wspomnianym zakazem używania antybiotykowych stymulatorów wzrostu, konieczne jest poszukiwanie naturalnych substancji, mogących wspomóc kontrolę składu jakościowego i ilościowego flory bakteryjnej ptaków. Celem niniejszego artykułu jest zaprezentowanie bieżącego stanu wiedzy, dotyczącej wpływu olejków eterycznych na skład mikroflory jelitowej kurcząt brojlerów. Artykuł stanowi przegląd badań in vivo, które dowodzą, że niektóre olejki eteryczne wykazują znaczny potencjał w zakresie oddziaływania na mikroflorę jelit.
