It is a lot of unused food, so it has much the same chemical composition as the feed that animals consume. All animals produce manure, but the kinds of environmental problems that arise on most farms generate from manure products rather than manure itself. Manure products result from manure storage and treatment systems. Odors are manure products. Anaerobic lagoons digest and transform the manure into methane, nutrients, carbon dioxide and water.
Broiler litter is a mixture of manure and the animal bedding.
Manures that are composted are also processed forms of manure. Manure has the capacity to be either a liability or a benefit. Generally, the liabilities arise when manure is not intensively managed. Intensive management and an awareness of the demand for manure products will result in a corresponding revenue for producers. Making this shift from defending an environmental issue to generating revenue, depends on a knowledge of available manure resources and what it is manure buyers demand.
