On the death of an equine, one must contact a squander quickly or an incineration company for the removal of the horse. I think we should not wait more than three days before contacting a company if not the rendering companies can refuse the horse ... You have to put a sheet on the horse is better if the horse is in an accessible place . I know that the declaration to the SIRE of the death of an equine is obligatory and is registered as soon as the papers of the equine are returned. I also know that since 2009 (I think) cremation is allowed. It's a very delicate subject.
