Cinnamaldehyde has
shown to have potent
immunomodulatory
effect (potentiated
immune response)
and improved
gut integrity
with enhanced
growth (Awaad et
al.,2014; Toghyani
et al.,2011). Actives
of Cinnamaldehyde
might have
maintained gut
integrity, protected
against pathogens
and contributed
towards better
growth. Multiple
actions of Thymol
include reduction
of pathogenic
microbiota,
boosting of the
antioxidant system
due to polyphenol
constituents
(Abdulkarimi et al.
2011)increasing
feed utilisation and
enhancing immunity
(Youssef et al., 2017;
