Purina® Hydration Hay

Hayblock Hayblock Hayblock

Purina® Hydration Hay Blocks are a premium blend of quality grass and alfalfa hay that have been compressed into convenient, lightweight blocks. Simply drop the block into a bucket with 5 quarts of warm water, and it will quickly expand into about one flake of palatable, moist hay. Recommended for all horses at all life stages.

Promotes Water Intake for Proper Hydration

The stress of travel can cause many horses to struggle with proper water intake when on the road. With Purina® Hydration Hay Blocks, your horse can receive consistent, quality forage and proper hydration at the same time when eating the moist hay.

Convenient, Lightweight and Easy to Use

Each block weighs only about 2 pounds, so they are easy to carry and feed, making them ideal for use while traveling.

Expands in a Bucket of Water

The patent-pending compression and hydration process allows a block to quickly expand into moist hay in a bucket of water.

Compressed Blend of Premium Grass and Alfalfa Hay

Contains consistent, quality grass and alfalfa hay that provide the nutritious roughage horses need.

Patent-pending Hydration Hay Soak Technology

After numerous scientific formulations, trials and refinements, we’ve found a way to deliver consistent, quality nutrition in a lightweight, convenient and easy-to-feed compressed block that horses love.

Reduces the Need to Haul Water and Large Bales of Hay When Traveling

Most horses prefer the taste of their water from home. But Hydration Hay Blocks mask the “odd” taste of foreign water sources, so you can use local water when on the road. No more hauling large, heavy bales of hay and water from home!

Convenient Way to Add Medications and Supplements

The moist hay is a great way to mask the taste of medications, dewormers and supplements to get them into your horse.

Chris Hickey, Purina Ambassador, talks about his experience with Hydration Hay Blocks, including the benefits of maintaining hydration in performance horses, masking the flavor of medications and introducing feedstuffs to a horse that has experienced mild colic.


At Purina, we’ve spent more than 100 years developing superior nutrition for horses. After numerous scientific formulations, trials and refinements for our new line of supplements, we’ve found ways to give horses the boost they need to be their best. No more trying to find a supplement that works. No more frustration and expense for ones that under-deliver.

Purina® Hydration Hay Blocks can be fed dry or soaked in water.

Soaking directions:
Place one 2-lb. Purina® Hydration Hay ORIGINAL Horse Hay Block in a large bucket. Add a minimum of 5 quarts of water. Allow product to absorb water prior to feeding (approximately 10 minutes). To facilitate more uniform absorption, flip the hay block halfway through soaking time. Additional mixing by hand may further accelerate water absorption.

Designed to replace a portion or all of the forage in a horse’s diet. Replace forage on a 1:1 ratio. Each 2 lbs. of dry hay can be replaced with one 2-lb. dry Purina® Hydration Hay ORIGINAL Horse Hay Block.

If replacing all forage in a horse’s diet, be sure to feed at a minimum rate of 1.0 to 1.2 percent of body weight (10–12 lbs. / 5–6 blocks for a 1,000-lb. horse) with 2.0 percent of body weight preferred. Inadequate amounts of forage may lead to colic and other digestive disturbances.
