For horse owners, managing sugar and carbohydrate intake is a daily concern, particularly for those dealing with metabolic conditions like Equine Metabolic Syndrome (EMS) or Laminitis. While commercially produced hay soaks are effective, they can be costly and require significant storage space. A do it yourself solution offers a practical, budget friendly alternative that allows for complete customization. Creating your own hay soaking tub is a straightforward project that can significantly improve your horse's health management.
Why Soak Hay Instead of Just Feeding It Dry
The primary reason to soak hay is to reduce water soluble carbohydrates, including fructans, which can trigger metabolic issues in sensitive horses. When hay is soaked, these sugars dissolve into the water, effectively lowering the non structural carbohydrate (NSC) content of the forage. This process is not just a trend; it is a medically recognized management strategy recommended by many equine veterinarians and nutritionists. However, constantly wet hay creates a perfect environment for bacteria and mold, which presents its own health risks if not handled correctly.
The Science Behind the Soaking Process
Understanding how a hay soaking tub works helps owners use the tool more effectively. When hay is submerged, osmosis occurs, drawing the sugars out of the plant cells and into the surrounding water. The length of the soak time directly impacts the reduction rate; however, there is a trade off to consider. While a longer soak removes more sugars, it also rinses out beneficial proteins and minerals. Finding the right balance is key to maintaining the nutritional integrity of the forage while addressing the medical needs of the animal.
Designing Your DIY Hay Soaking Tub
The most successful DIY projects start with a solid plan, and a hay soaking tub is no different. You have two primary approaches to choose from: converting an existing object or building a dedicated structure. The goal is to create a system that holds water, allows for easy loading and unloading, and drains thoroughly to prevent the hay from sitting in its own residue.
Option 1: The Tote Conversion Method
This is often the simplest and most affordable route for the average stable. It involves purchasing a large plastic storage tote, typically used for organizing tools or household items. Look for a tote made of thick, UV resistant plastic that can withstand constant moisture and the weight of wet hay. The main modification involves drilling a series of drainage holes in the bottom. These holes must be large enough to allow water to escape when the tub is tilted, but not so large that they let hay chips or chunks fall through and clog the drain.
| Material | Recommended Specification |
| Tote Size | 30 to 50 Gallons |
| Plastic Type | High Density Polyethylene (HDPE) |
| Drainage Holes | 1/2 inch to 3/4 inch diameter |
Option 2: The Cradle and Trough System
For those with larger operations or specific aesthetic preferences, building a cradle system is a more permanent solution. This design involves constructing a sturdy frame, often made from pressure treated lumber or metal conduit, that holds a flexible rubber feed tub or a custom fabricated plastic tray at an angle. The pitch allows the water to drain into a trough or directly into the ground. This method is ideal for those who process large volumes of hay daily and need a system that integrates seamlessly with their barn workflow.
Step-by-Step Construction and Usage
Once you have selected your design, the construction phase begins. If you are modifying a tote, remember to create a stable base. A cut-out section on one side, acting as a spout, makes it significantly easier to fill a wheelbarrow or lead bucket with the nutrient rich water for landscaping rather than wasting it. When building a cradle, ensure the frame is level and the tub is securely fastened to prevent shifting during the agitation process.
Using the tub is relatively simple but requires a routine. Fill the tub with the hay and then add water. Agitation helps the sugars leave the plant matter more quickly; you can gently stomp on the hay or use a hay whip. After the recommended soak time—usually between 30 to 60 minutes—lift the hay and allow it to drain in the tub or over a wheelbarrow. Never let the soaked hay sit in the dirty water, as this reintroduces bacteria to the clean feed.
Maintenance and Safety Considerations
Hygiene is paramount when using a hay soaking tub. The dark, wet environment left behind by the hay is an ideal breeding ground for bacteria and fungi. After every use, the tub must be thoroughly scrubbed with a stiff brush and a safe disinfectant. If you notice any slime, unusual odors, or discoloration, the tub requires a more intensive cleaning protocol immediately. Regular maintenance protects your horse from ingesting harmful pathogens that could cause digestive upset.
Finally, consider the physical placement of your new tub. Position it on a firm, level surface to prevent tipping and ensure safe handling of the heavy, soaked hay. Position the drain spout so that the grey water flows away from the horse's living area to prevent mud fever or the creation of a slipping hazard. With a well constructed hay soaking tub, you transform a necessary chore into a controlled process that actively supports your horse's long term health and well-being.
