Our multistate group of state horse specialists produced and evaluated impacts from six webinars and online short courses (webinar plus additional content) addressing current industry issues: pasture-associated laminitis, equine herpesvirus-1, disaster preparedness, sales fraud, rescues/rehoming, and manure management. We identified no differences in perceived knowledge gained from webinars or short courses; however, results suggest that participation in short courses versus live webinars may be more useful for making positive management decisions. Short course participants also reported greater potential for cost savings as a result of completing the education. On the basis of the study, we offer recommendations for developing effective online Extension education programs.
