Digestive Supplements for Horses

The horse has a small stomach and accounts for about 10% of the horse’s digestive tract. The food enters the stomach and remains there for approximately 30-45 minutes and only fills to about two-thirds ending up in the small intestine before it has been treated by the stomach’s digestive juices. When you combine that with increased stress associated with high-level performance, it is essential that you are providing your horse with a supplement that supports digestive health especially with the amount of processed food that enters the system. Our wide selection of digestive supplements provides horses with the preventative care they need for a healthy system. These supplements also treat ulcers and other discomforts by using in powder, liquid, pellet, paste, or gel form. Choose from trusted brands including Vitaflex, Finish Line, Uckele, Cox Vet Labs, Farnam and more.

SayWhoa for Colic and Digestion Gel Syringes - TB
Big Dee's Tack and Vet Supplies

SayWhoa! Fecal Impaction, Gas, Light Sand & Spasmodic. SayWhoa! is not a drug. It does not contain pain reliever or muscle relaxant properties. No pain medications are needed since relief starts within minutes. Through osmosis fluids return to the gut, where they are needed. Ionic solution assists in the peristalsis returning. Gut sounds are heard because peristalsis has returned. Horses start back to eating within 1-2 hours.

How it works differently: It is absorbed into the blood stream and instantly starts breaking down fecal matter and fecal impactions. It is not a muscle relaxant, so smooth muscles can keep doing their job of allowing the normal peristalsis or bowel motility to move materials towards elimination.

Product Details:

  • Safe for Horses any size or weight, including lactating mares, mares in foal and performance horses
  • 2 pre-filled 60 ml Syringes
  • Promotes digestive sounds to return quickly
  • Eliminate nasal tubing
  • Temperature: Store at Room Temperature. May adapt to temperatures between freezing and 115 F. If freezes just thaw out and use will not affect the product.
  • Keep out of the reach of children.
  • 3 Year Shelf Life
  • Made in the USA

Please note: After administering the product, your horse will appear to be improving. You should hear returning and/or stronger bowel sounds, on both sides, and wanting to eat in 1 to 2 hours if this is a normal bout. However, if after waiting for 30 minutes, no sounds return and your horse does not appear better, then contact your vet immediately as your horse may be having an abnormal bout.

Kentucky Performance Neigh Lox Equine Antacid  3.5 lb - TB
Big Dee's Tack and Vet Supplies

Neigh-Lox's research-proven, patented formula supports a healthy stomach by neutralizing excess gastric acid and coating the stomach's sensitive lining . The combination of buffering and coating ingredients maintains a normal stomach environment that helps prevent ulcers from forming. It also supports the healing of minor ulceration. Long-acting Neigh-Lox neutralizes excess acid and coats the stomach lining for up to 8 hours, while other antacids buffer for much shorter periods.

Equine gastric ulcer syndrome (EGUS) is a widespread problem among all horses.

  • The prevalence of gastric ulcer damage has been documented in 93% of horses in race training, in nearly 60% of other performance horses, and in 57% of all foals
  • Recreational horses and broodmares are also at risk
  • Preventing and treating EGUS is a challenge faced by many veterinarians and horse owners
  • Neigh-Lox has the capacity to buffer for a long period of time (minimum 6-8 hrs); most antacids buffer for a much shorter period
  • Neigh-Lox buffers large amounts of acid; one dose ( 4 oz) has 240 mEq of acid-neutralizing capacity, which is equivalent to the amount of gastric acid typically produced over a six-hour period
  • In addition to its buffering capabilities, Neigh-Lox also contains compounds that coat the lining of the stomach and adhere to gastric lesions, which maintains healthy mucosa and supports healing

Neigh-Lox's pelleted form makes it easy to administer, either along with a meal or on its own.
