A few customers reaching out lately, with suspected ulcer symptoms. Here are some reminders of what symptoms may show in horses with digestive discomfort and be aware that over half do NOT show 'typical' physical symptoms (as per 2015 study).
- RELUCTANCE TO EAT - not eating hard feeds, picky eaters, only eating a little bit of hard feed, disinterest in eating hay and in more serious cases disinterest in eating in general - any of these are NOT NORMAL AND ISN'T JUST THEIR QUIRK OR ALWAYS BEEN LIKE THAT
- WEIGHT LOSS/POOR CONDITION - goes hand in hand with poor appetite, not absorbing nutrients fully or at all, loss of muscle generally and top-line, ribs showing no matter what you feed
- POOR COAT - aligns with the first 3 especially poor absorption of nutrients. Parasites and Mineral imbalance also can impact here - lack of zinc and copper especially in relation to Iron is a big one.
- CHRONIC DIARRHEA/COLIC - Horses can get loose manure from change of diet or high anxiety but ongoing chronic unresolved can point to ulcers. "In one study, 83% of horses with recurring colic were found to have gastric ulcers. Researchers directly linked ulcers to colic in 28% of those horses (as documented by the response to an acid-suppressive treatment)."
- BEHAVIOUR CHANGES - this is the main one people tend to focus on often ignoring the more subtle symptoms. May be nervous/spooky under saddle, more aggressive at feed time or with other horses, grumpiness or aloofness.
SENSITIVITY IN GIRTH - another one that people mainly focus on. The hind gut is impacted with the girthing motion. Research has shown 92% of horses with “girthiness” were found to have gastric ulcers.
NZ SPRING grass can also be party to creating issues in the horses digestive system - excessive protein, lack of dry matter, major mineral imbalances combined with typical unbalanced processed horse feeds.
These are the main things to look out for but other symptoms can include:
Stretching as if to urinate frequently, teeth grinding, cribbing, Excessive Salivation or laying down, poor performance, body soreness especially unresolved lower back pain, not wanting to be caught, depressed, resistance to grooming, not moving forward under saddle, biting at riders feet, cold backed, wringing/swishing tail when ridden, licking out when ridden and some more uncommon signs:
Stiff neck and shoulders, problems with stifles, tension in groin area, swollen glands under jaw bone, thyroid gland problems.
What causes and what can you do coming soon! We like to take a holistic approach to digestive dysregulation. On a quick note if your horse is competing and travelling regularly - HHIO Support is a must to help navigate ongoing stress in the body and to gently support the digestive system. Remember 30g is for a maintenance dose, 60g for higher stress loads and 90g for ulcer/digestive issues.
This is alongside a HHIO mineral formula to address excessive iron levels in diets among other things and lastly why the clean feeding regime we recommend in conjunction with our formulas is so important as it too is conducive to helping and supporting a healthy and robust digestive system.
