The importance of fiber: What is it and why do horses need it?

What is fiber?

Fiber is made up of several different types of carbohydrate and is the carbohydrate that horses cannot digest in their small intestine, but rather ferment in their hindgut. Fiber is called many different names, including ‘structural carbohydrate’, bulk, roughage, crude fiber … the list goes on. Note that some fibre is indigestible, and it is this fibre that passes in the feces..

Why do horses need fiber?

Fiber plays 3 major and very important roles in the diet of horses. These are:

What happens if a horse doesn’t get enough fiber?

Diets that don’t provide a horse with enough fiber can cause major problems including:

What types of feed are high in fiber?

As you can see fiber is absolutely essential in a horse’s diet. The fibre in these feeds is not always the same, and can be digestible, indigestible, and either long fibre or short fibre. 
Feeds that contain a lot of fiber include: 
Long fibre

Short fibre

How much fiber does a horse need per day?

The general rule of thumb is a horse should be fed an absolute minimum of 1% of its bodyweight as long fibre per day. This is equivalent to 1 lb/100 lb bodyweight (which equals 10lb/day for a 1000lb horse).   Preferably a horse should be fed at least 2% of its bodyweight per day in fibrous feeds. This level will keep the horses gut full and provide plenty of feed to chew on to stimulate saliva production.
The short fibre feeds are useful to provide digestible fibre as an energy source. Further, some feeds such as CoolStance have a high water holding capacity (0.5 gallons water per lb CoolStance). This is useful for overcoming dehydration and anhidrosis.

Role of fiber in Equine Metabolic syndrome

Feeding horses with high NSC related disorders (EMS, tying up, colic) required that the total NSC in the diet be reduced, usually by feeding medium quality grass hay. It is essential that these hays do not contain seed heads (grain). Under acute conditions, it is often necessary to soak the hay to extract the soluble NSC from the hay leaves and stems, prior to feeding.

The last straw!

Horses evolved eating a high fiber diet and fiber is still the single most important component in your horse’s diet aside from water. If your horse isn’t getting enough long fiber it can be facing serious consequences including colic, dehydration and diarrhoea.  With EMS horses, feed only low NSC hays. 

CoolStance as a source of fibre

Although CoolStance contains 15% crude fibre, it is a high energy feed, because of the oil content, and that the fibre length is short.  CoolStance has a high water holding capacity (essential for horses that will not drink), and a low NSC (<12%).  CoolStance can be fed together with medium quality grass hays, and is suitable for most horses.
