Timothy Hay for Horses: Benefits, Nutrition, and When to Feed It

Scientific guidance provided by Dr. Stephen Duren and Dr. Tania Cubitt, internationally recognized equine nutrition scientists at Performance Horse Nutrition

When we talk about foundational nutrition for horses, it always starts with forage. Among cool-season grasses, timothy hay for horses has earned a reputation as one of the most reliable and versatile forage options available. Whether you are feeding performance horses, broodmares, seniors, or easy keepers, timothy hay can be a powerful part of a balanced feeding program when used correctly. Horse owners often compare timothy hay vs alfalfa hay for horses when deciding which forage best supports their horse’s nutrition. Understanding how timothy hay works nutritionally helps horse owners decide when it is the right forage and how to incorporate it into a feeding program.

What Is Timothy Hay?

Timothy (Phleum pratense) is a cool-season perennial grass commonly grown in the northern United States and Canada.

It is easily identified by its cylindrical seed head, often referred to as a “cat-tail” head.

Timothy hay is widely used in:

• Horse operations

• Dairy and beef cattle programs

• Small ruminant feeding

• Export hay markets

For horses specifically, timothy hay is valued for its palatability, moderate energy levels, and predictable fiber profile.

Typical Nutrient Profile of Timothy Hay

Like all forages, nutritional values vary depending on harvest timing, maturity, and growing conditions.

However, a typical analysis of timothy hay for horses often falls within the following range:

• Crude Protein: 7–11%

• Neutral Detergent Fiber (NDF): 55–65%

• Acid Detergent Fiber (ADF): 32–40%

• NSC (WSC + Starch): Often 10–15% but should always be tested

• Calcium: ~0.3–0.5%

• Phosphorus: ~0.2–0.3%

These values make timothy hay a moderate-energy forage that works well in many horse diets. Read a full equine nutrition analysis of Blue Mountain Hay by Dr. Stephen Duren and Dr. Tania Cubitt of Performance Horse Nutrition here.

Why Timothy Hay Is So Popular for Horses

1. Excellent Fiber for Hindgut Health

Timothy hay provides the type of fiber needed to support proper digestive function.

It helps provide:

• Effective fiber for gut motility

• Substrate for microbial fermentation

• Support for consistent manure quality

For horses prone to digestive upset, clean and well-cured timothy hay for horses can provide a very stable base forage.

2. Moderate Energy Density

Timothy hay generally contains less digestible energy than alfalfa hay, which can help provide better calorie control.

This makes it especially useful for:

• Pleasure horses

• Retired horses

• Horses prone to obesity

• Horses with metabolic concerns

Because of its moderate calorie content, timothy hay can help maintain healthy body condition without excessive energy intake.

3. Excellent Palatability

Timothy hay is widely accepted by horses.

It is typically:

• Soft-stemmed (especially second cutting)

• Leafy

• Highly palatable

Palatability is important because consistent forage intake supports digestive health and overall metabolism.

First Cutting vs Second Cutting vs Third Cutting Timothy

The harvest stage of timothy hay significantly influences its nutritional value.

First Cutting Timothy

• Coarser stems

• Higher fiber levels

• Lower digestible energy

Often ideal for easy keepers or horses needing lower calorie intake.

Second Cutting Timothy

• Leafier texture

• Softer stems

• Slightly higher protein levels

Often preferred for performance horses or horses needing higher quality forage.

Third Cutting Timothy

• Very fine stems

• Highly digestible

• Often richer in nutrients

Not available in all regions but can be useful in certain feeding programs.

However, maturity at harvest is often more important than cutting number.

An early first cutting may test nutritionally better than a late second cutting.

Timothy Hay vs Alfalfa Hay for Horses

Timothy hay and alfalfa hay are often compared, but they serve different roles in a feeding program.

Timothy typically provides:

• Lower protein levels

• Lower calcium levels

• Moderate energy

• Higher fiber

Alfalfa typically provides:

• Higher protein

• Higher calcium

• Higher calorie density

Because of these differences, many feeding programs combine both forages.

A common approach is:

• Timothy hay for fiber base

• Alfalfa hay to increase protein and calcium

For performance horses, this combination can help support muscle development, buffering capacity, and overall nutrition balance.

Is Timothy Hay Low in Sugar?

Not automatically. The non-structural carbohydrate (NSC) content of timothy hay depends on several factors:

• Time of day harvested

• Weather conditions

• Plant maturity

• Soil fertility

If you are feeding horses with metabolic concerns such as:

• Equine metabolic syndrome (EMS)

• Insulin resistance

• PPID (Cushing’s disease)

it is important to test hay rather than assume sugar levels based on forage type.

What to Look for in High-Quality Timothy Hay

When selecting timothy hay for horses, look for:

• Bright green color

• Fresh smell

• Soft stems

• High leaf content

• Minimal dust

• No mold

• No weeds

Leaf content is especially important because many nutrients are concentrated in the leaves.

For larger horse operations, working with a consistent hay supplier and testing forage regularly can help maintain stable nutrition.

Horses That Benefit Most from Timothy Hay

Timothy hay works especially well for:

• Easy keepers

• Horses in light to moderate work

• Horses needing controlled calorie intake

• Horses sensitive to high calcium diets

• Base forage in mixed hay programs

For horses with higher calorie demands, timothy hay may be paired with:

• Alfalfa hay

• Concentrates

• Added fat sources

The Bottom Line: Is Timothy Hay Good for Horses?

Timothy hay remains one of the most trusted forages for horses because it provides:

• Consistent fiber

• Moderate energy

• Excellent palatability

• Flexible use across many classes of horses

As with any forage, the most important factors are harvest timing, growing conditions, and laboratory analysis.

Forage is not filler. It is the foundation of the equine diet.

When timothy hay is harvested and managed correctly, it can form the foundation of a balanced and effective feeding program for horses.

Frequently Asked Questions About Timothy Hay for Horses

Is timothy hay good for horses?

Yes. Timothy hay is a widely used grass forage that provides consistent fiber, moderate energy, and good palatability. It works well as a base forage for many types of horses.

Is timothy hay lower in protein than alfalfa?

Yes. Timothy hay typically contains 7–11% crude protein, while alfalfa hay often contains 16–22% protein, making alfalfa more nutrient-dense.

Which is better for horses: timothy or alfalfa?

Neither forage is inherently better. Timothy hay provides moderate energy and fiber, while alfalfa provides higher protein and calcium. Many feeding programs combine both to balance nutrition.

Is timothy hay low sugar?

Not necessarily. Sugar levels in timothy hay vary depending on growing conditions, harvest timing, and maturity. Horses with metabolic conditions should always have hay tested.

What cutting of timothy hay is best for horses?

Second cutting timothy is often preferred because it is softer and leafier. However, the maturity of the plant at harvest is more important than the cutting number.

What does good quality timothy hay look like?

High-quality timothy hay should be bright green, leafy, fresh-smelling, soft-stemmed, and free of dust, mold, or weeds.
