Horse Trust-Funded Research Confirms Link Between Ammonia and Respiratory Problems in Horses
Horse owners have long worried about the ammonia smell in stables, but there has been little scientific evidence to back this up. These findings confirm that ammonia is linked to poor respiratory health, although further research is needed to confirm whether and how ammonia causes respiratory problems.
It is unclear at present how ammonia impacts respiratory disorders in horses, but in other animals exposure to ammonia has been found to result in increased mucin production and reduced pulmonary clearance.
In the next phase of his research project funded by The Horse Trust, Professor Love’s team are carrying out a large-scale field study to quantify the environmental risk factors – such as bedding, feeding and ventilation – that predispose horses to respiratory inflammation. The results from this field study will be available next year.
Professor Sandy Love has also developed an apparatus – constructed using components readily available from a DIY store – that can be attached to a horse’s head to capture its breath and condense the liquids within the expired air. This device could be used by vets to monitor respiratory inflammation. At present, the only techniques available to monitor respiratory inflammation in horses are invasive, such as endoscopy.
“We are pleased that the research The Horse Trust has funded has improved understanding around the causes of respiratory problems in horses. We look forward to receiving the results from the final stage of Professor Love’s research, which we hope will give horse owners practical advice about how to reduce the risk this distressing condition.”
