As soon as an animal dies, its body’s metabolism stops. The decomposition process begins after 24 to 48 hours. How long decomposition lasts depends particularly on the oxygen supply and the ambient temperature. Depending on the animal’s size, the decomposition process affects its body and appearance to different degrees. Deceased horses are usually more affected by the decomposition process than smaller animals. It is advisable to store the animal’s body in a cool place (below 10°C) as soon as possible after its passing and make a decision on what to do about it.
