Mortalities happen. And under Alberta’s Destruction and Disposal of Dead Animals Regulation of the Animal Health Act, Appendix A, the owner of a dead animal shall dispose of the animal within 7 days of its death. Mortalities can be composted, incinerated, buried, rendered or naturally disposed. Today, animal agriculture is challenged to discover innovative ways to dispose of livestock and poultry mortalities. Composting of livestock mortalities is one option. There are two general approaches to livestock mortality composting: bin systems and windrow systems.
