Straight from the horse’s stomachSeptember 2019
Story by: Stephanie Craig Horses are highly adapted performance animals, but one unexplained adaptation – a delicate gastrointestinal tract – is their Achilles heel. As in humans, horses’ stomachs contain acid to digest and break down their food and mucus to protect the stomach wall against the acid. But for a vaguely inexplicable reason, horses lack mucus in the upper half of their stomach. This causes all sorts of issues, including gastric ulcers.
“If acid splashes up, or their stomach is empty, it can really damage a horse’s stomach,” explains Jennifer MacNicol, a PhD candidate in the Department of Animal Biosciences. “But what if we can keep food in there longer and potentially buffer that splashing, or use nutraceuticals to reduce acid production or increase mucus production?”
An in vitro protocol simulates digestion in different compartments of a stomach. She hopes this will be a less invasive way to conduct equine research. “I think as scientists we have an obligation that if we use live animals, we need to make sure they are the most directed and valuable studies,” Jennifer says. “I want to develop strong and robust in vitro methods so that we can do a lot of things before taking it into the live animal.”

Pickles isn’t typically allowed in the lab, but it seemed fitting to let him share the limelight. He’s been with Jennifer throughout her three degrees at the University of Guelph. |
