I have no idea, but here is a link to a site where you can ask a horse vet a question. http://www.justanswer.com/large-animal/horse/equine?r=ppc|ov|1|Pets+%2D+Large+Animals|Horse&JCRN=Horse+Vets&JPRC=1&JPKW=horse%20vet&JPKD=317953745011&JPDC=S.adv&JPAD=52244244511&JPRQ=ask%20a%20horse%20vet&JPAF=txt&JPCD=20090223-1 You at least have a chance of getting an intelligent answer there, but it costs $20.
