For small- and medium-sized carcasses (for example, poultry, pigs, sheep) the active composting period (phase I) may be up to three months before the pile is turned (Keener et al., 2000). This publication serves as a reference for producers regarding options of carcass disposal. Research Institution. (NDSU photo). Rynk, R.F. Mammal carcasses are about 50 percent water and 20 percent protein. Odor nuisance complaints generated due to a poorly functioning incinerator are common. Xu, W., Reuter, T., Inglis, G.D., Larney, F.J., Alexander, T.W., Guan, J., Stanford, K., Xu, Y., and McAllister, T.A. Northeast Regional Agricultural Engineering Service. Step Five. Odor can be kept to a minimum as long as the pile is turned to aerate it and the covering material has enough carbon sources, such as straw, sawdust or hay, to provide a 25:1 ratio of carbon to nitrogen. Bones, which degrade very little, can be pulverized to spread on fields, creating good fertilizer. As per 2016 U.S. Department of Agriculture-HPAI response mortality composting guidelines, suitable carbon sources are key for proper windrow or pile preperatrion and maintaining a consistent temperature during composting. If you do not know why an animal has died you should always think of the diseases which humans can catch from animals like rabies, anthrax and others.

Also, incinerators must be loaded and operated according to the manufacturer’s recommendations. Composting is a naturally occurring process in which the dead animal is broken down into basic elements (organic matter) by microorganisms, bacteria and fungi. Original legislation for the management of dead animals in Missouri was developed in the 1940s. However, during mortality composting, piles are left undisturbed during the first stage of composting (phase I) to ensure soft tissue is decomposing properly. For the Sales Price you would enter 0 (zero). Shafiqur Rahman, Associate Professor, North Dakota State University, Mary Berg, Area Extension Livestock, Environmental Management Specialist, North Dakota State University. NDSU Extension Service publication AS1781. In many areas, the numbers of rendering facilities are limited and in many cases are declining due to increased costs and biosecurity risks associated with transporting mortalities (Glanville et al., 2009). If you suspect BSE, contact the IDOA or USDA Veterinary Services for sampling prior to disposal. Subscribe now! Incineration is the thermal destruction of carcasses by auxiliary fuel such as propane, diesel or natural gas. The disposal trench bottom should be compacted and mortalities should be placed in 3- to 4-feet layers in the disposal trench. ... Dead Animal Disposal Act. 2009. Burial must be no less than 6 feet deep with a minimum of 30 inches of soil cover. Journal of Environmental Quality. A dead animal may be placed at one end of the trench and covered with soil. Prompt burial will prevent nuisance problems such as odors, flies and scavengers. 102(3): 609-618. Burial is difficult during winter and not an option during flooding or in areas prone to flooding. At least three bins usually are in operation at any time. Small and medium-sized carcasses can be composted in a three-sided enclosure (for example, a bin) constructed on compacted clay soil or a concrete floor (Figure 2). 1992. Resources from UMass Extension and the Center for Agriculture, Food and the Environment: ag.umass.edu/coronavirus. As a general guide, 3 to 5 cubic yards of co-composting material is required for every 1,000 pounds of carcass (Auvermann et al., 2006). Rendering is the process of converting dead animal bodies to pathogen-free useful byproducts such as protein for agricultural feed. Glanville. Burn Barrels/Open Burning (Ag Waste Burning, Sec. Ithaca, N.Y.: Northeast Regional Agricultural Engineering Service (NARES). Overview of Animal Feeding Operations Iowa has two types of DNR-regulated animal feeding operations (AFOs): confinements and open feedlots. This is a step-by-step look at the composting pile construction procedure:  breaking up a round straw bale. Tie a knot in the top of the bag. Step Three. Composting is the preferred method of carcass disposal because it can be implemented rapidly on farms at minimum cost. Love this story? Digestion of dead animals shall be accomplished in a properly designed and sized dead animal digester approved by the Executive Director. As one bin is being filled, another is in the primary stages of composting and the third is in the secondary stages (secondary heat cycle) of composting. A base of sawdust, wheat straw, or other suitable carbon source 12 to 18 inches in depth is required, depending on carcass size. The Missouri Dead Animal Disposal Statute was passed by the 86th General Assembly and … This is a step-by-step look at the composting pile construction procedure: laying the straw base and measuring the perimeter after laying carcass.

There will be less bony residue with younger carcasses.Calves, for instance, may compost in three to four weeks under summer conditions. This means you save up to 65% on fuel consumption, a savings of more than a gallon of fuel per hour. Carcasses can be added anytime but should be spaced about 4 feet apart. They need to think about mortality management before a death occurs to avoid having problems after the fact. Also, it's probably not a great idea to go around reading articles called things like Virginia Coperative Extension. On-farm composting of dead animals generated on the same farm as the composting facility is exempt from having a permit if operated in compliance with the Massachusetts Department of Agriculture regulations. However, rendering poses biosecurity concerns due to the transportation of livestock mortalities to multiple locations en route to the rendering plant (Fonstad et al., 2003). The bulking material, such as cornstalks and tree trimmings, needs to provide porosity and structure to a compost pile; therefore, manure is not the ideal choice. Choose an area where tractors can maneuver in all weather. Step Four. Or they can be left in the pile. (Refer to MDAR 330 CMR 25:00). 2009. Open-pit or open-pile burning should be a method of last resort. If at all possible, don't touch a dead animal or at least wear gloves. There is an old saying, "where there are livestock, there are 'deadstock'." Typically, a minimum 12- to 16-inch layer of co-composting material around all sides of the carcass will discourage predators, control odors and eliminate flies.

When another carcass needs to be added, the carcass can be placed in the trench immediately and covered even if the ground is frozen. NDSU Extension publication V561. Often, excessive pollutants can build up in burial sites, and leaching of nitrogen and phosphorus into water bodies causes eutrophication (Turan et al., 2007). Construct a windrow 10 feet wide by 4 feet deep of the dry manure and bedding mixture. (NDSU photo). However, selection of a proper composting site is important to prevent surface water runoff to the compost site and runoff of leachate from the compost site, as well as leaching of raw or finished compost nutrients to groundwater.
