Why Is Proper Mortality Management Important?

Proper management of animal mortalities has important implications for nutrient management, water quality, animal health, and farm/ranch family and public health.  To best ensure human health and safety, reduce regulatory risks, and protect environmental resources, livestock producers should become familiar with best management practices (BMPs) for dealing with dead animals. Producers should also be aware of state laws related to proper disposal or processing of mortalities. 

Mortality composting is an increasingly popular and viable alternative when compared to other disposal practices because of cost savings, bio-security benefits, and reduced environmental risks.  Static mortality composting differs from traditional composting in both management intervals and carbon to nitrogen ratios.   The objective of this workshop is to provide those who advise livestock producers with the knowledge, tools, and resources to develop a mortality management plan, with specific focus on the static composting option.   

The Rocky Mountain based authors conducted demonstrated research, reviewed pertinent literature, studied USDA-NRCS standards, and documented mortality composting systems already in-use by regional producers.

Curriculum Materials

Data from these activities provided a basis for the following tools:

  1. Decision aid spreadsheet that evaluates the costs of mortality composting against other mortality disposal options (in English and Spanish),
  2. How-to-manual on mortality composting in English and Spanish),
  3. Video illustrating on-the-ground mortality composting
  4. PowerPoint presentation explaining mortality composting principles, methods and resources (in English and Spanish).

Learning Objectives

This 90 minute in-service workshop will provide background and step-by-step considerations for mortality composting, with an emphasis on the practice in the semi-arid environments of the western United States.  However, fundamentals of the workshop will apply to all climates.   To the right, you will find recordings of the authors presenting the workshop using the slides from the curriculum materials.
