Many changes in the herd cause stress and reduced immunity!

Horses in a boarding stable don't always have it easy. Turnover in boarding stables is generally higher than in private ownership. And as horse owners, we all know that horses are herd animals. But did you also know that changes in the group cause stress and therefore a decreased immunity? Read in this blog how this works.

Stable herd = safety and security

Horses naturally live in herds, with a clear leader and mutual friendships and relationships. Each horse holds a certain place in the hierarchy in relation to another horse. They make way for one horse and not for another. This creates a balance in the herd. And this balance is important for overall safety and feelings of security. The herd can then peacefully graze, rest, play, groom, and relax. Stress only occurs when there is danger, but once the danger is gone, the herd returns to a state of relaxation.

Unstable herd = stress and unrest

In many (boarding) stables, there is a constant coming and going of horses. Horses stay for a few months to a few years and then leave for another place (with or without the current owner). Horses are sold, move, or pass away, preventing the herd from forming.

Each time a horse leaves or joins, the hierarchy must be reestablished. Even if it is a submissive/easy/stable horse. The bonds are re-evaluated, horses must learn to trust the new horse, and the new horse must learn who is in charge and who is not. New friendships are made, but it is also determined who is or remains the boss. A herd change therefore involves a lot of activity within the herd! It may appear calm on the surface, but a lot is happening underneath. Also, realize that it can take up to a year for a horse to completely trust its new place. A move has a significant impact and always causes stress.

Stress leads to reduced immunity

A horse's immunity is always under pressure during a move. In the new environment, there are different bacteria/viruses/organisms that challenge the horse's immunity. Additionally, the horse experiences stress, which may not be visible physically but is present internally. Everything is new, smells different, the daily routine is different, there are different horses and different people. Everything is different for the horse internally causing stress. Stress leads to reduced immunitybecause the body shifts into survival mode. In an acute stress situation, more cortisol is produced which is anti-inflammatory in the short term. However, in the case of a move, it can be considered chronic stress. The stress createdmore waste products in the body, leading to more inflammatory reactions and decreased immunity of the horse.

It is not uncommon for horses to develop a runny nose, be slightly sick, or even colic shortly after a move.

Limit herd changes!

This is especially important for stable owners, but also for those who have horses at home. Try to limit herd changes as much as possible. The fewer changes, the more stable the herd, and the less stress the horses experience. This not only provides a better living environment for the horse, but also benefits overall immunity and health.

If there are many changes on a boarding stable, this often indicates something about the policies of this stable. Keep this in mind when looking for a new place for your horse!
