GUT BACTERIA, VITAMIN B1 AND BEHAVIOUR… ARE THEY LINKED?

The short answer is yes! Here is how:

Vitamin B1 has been observed to have an influence on behavior in multiple animal species, including horses. A horse will meet its vitamin B1 requirements via the vitamin B1 it eats in its diet and from vitamin B1 produced by the bacteria in its hindgut.

There are two main families of bacteria living in your horse’s hindgut:

1. The fiber fermenting bacteria who love to ferment fibre from the forage your horse eats. These little critters are the ones we consider the ‘good bacteria’; and
2. The starch and sugar fermenting bacteria who prefer to ferment starch and sugars. These we generally consider to be the ‘bad bacteria’.

The good bacteria PRODUCE vitamin B1 that your horse can then absorb and use.

On the other hand, the bad bacteria produce a compound called ‘Thiaminase’ that actually destroys vitamin B1 (also known as thiamine) that is in the gut, making it useless to your horse.

If your horse has too many bad bacteria, and not enough of the good ones your horse may not get enough vitamin B1 and behavioral changes may occur.

How do you avoid this? Keep your horse’s hindgut healthy with an abundant population of good bacteria. The main two things you should do to achieve this are:

1. Feed lots of forage!; and
2. Never feed uncooked grains (with the exception of oats for some horses)
