Valerian and maypop may decrease stress in growing pigs as assessed by hair cortisol if administered
over a long period of time. However, further research is required to confirm these preliminary results
Plants have been used since ancient times in medicine and
in veterinary science as palliative or preventive treatments
(e.g. astringent, sedative, anti-inflammatory, antiparasitic,
blood stimulant, antiseptic, etc.). Maypop and Valerian have
sedative properties.
Otherwise, hair cortisol analysis is thought to be a good
non-invasive procedure to detect chronic stress since
cortisol is incorporated and stored inside growing hair.
Determine whether phytoteraphy could be
used to reduce stress in growing pigs

Significant differences in hair cortisol levels were found
between pigs supplemented with and without phytoterapy
after two months of administration, but no differences were
detected in saliva levels.
Hair and saliva cortisol levels were not correlated, probably
because the levels in saliva can be detected after a few
minutes, but it accumulates over days in hair.
