Summary

Equine squamous gastric disease (ESGD) remains prevalent and welfare-compromising despite routine omeprazole treatment, prompting investigation into whether management modifications alone could facilitate healing. Fourteen mares previously diagnosed with moderate-to-severe ESGD (baseline scores 3.36–3.57) were managed in individual stalls with daily exercise and fed ad libitum hay plus modest concentrates (1 kg low-starch compound feed daily), with half receiving a collagen-supplemented feed and half serving as controls. Both groups demonstrated significant lesion regression within four weeks—dropping to ESGD scores of 1.43 and 1.89 respectively—with 50% of horses achieving complete healing (scores <2), yet no statistically significant difference between supplemented and control groups (p = 0.75), suggesting management changes rather than the collagen compound drove improvement. The findings indicate that severe squamous gastric ulceration can resolve without pharmacological intervention when horses receive consistent forage-based nutrition, minimal concentrate supplementation, predictable daily routines, and stable human contact—implications that warrant reconsideration of omeprazole dependency and highlight the primacy of husbandry optimisation in ESGD management protocols.

Practical Takeaways

  • Severe ESGD can improve or heal through management changes alone—provide ad libitum forage with minimal concentrate and establish a consistent daily routine without necessarily relying on omeprazole
  • Environmental stability matters: a predictable schedule with the same caretakers may significantly reduce stress-related gastric disease, suggesting husbandry improvements should be prioritized
  • Expensive gastric supplements may not be necessary for ESGD recovery; focus resources on diet and management optimization instead

Key Findings

  • ESGD scores significantly reduced in both groups after 4 weeks (supplement group: 3.57 to 1.89, control group: 3.36 to 1.43, p < 0.01)
  • Healing of ESGD (scores < 2) occurred in 7 out of 14 horses regardless of supplement group
  • No significant treatment effect observed between hydrolysed collagen supplement and control groups (p = 0.75)
  • Management changes including ad libitum hay feeding, limited compound feed, predictable routine, and dedicated caretakers improved gastric health without omeprazole use
