It’s been proven that carrying extra pounds can cause humans to develop asthma, and researchers are now attempting to find a link between obesity and breathing issues in horses.
Texas A&M and the Morris Animal Foundation are funding research on the debilitating condition. Currently, the main treatment option for asthmatic horses is the use of corticosteroids, which can cause laminitis in overweight equines.
Texas A&M researcher Dr. Michelle Coleman intends to use 60 horses brought to the University’s veterinary teaching hospital for the study. The research team will assess each horse’s body condition, identify if they have insulin issues, and determine their asthmatic state by listening to their lungs and taking fluid samples from their lower airways. The horses will be divided into four groups of 15: Obese and asthmatic, non-obese and asthmatic, obese and healthy, and non-obese and healthy.
Each group will be examined for inflammation markers, including cytokine levels. The cytokine levels in humans differ between obese asthmatic people and non-obese asthmatic people. The study will also look at each horse’s lung microbiota to see if there is a difference in obese asthmatic horses and non-obese asthmatic horses.
Researchers hope the results from the study will allow horse owners and veterinarians to identify horses at higher asthmatic risk and assist in preventing asthma or intervening in such situations earlier.
