ANIMAL WASTE MANAGEMENT / LIVESTOCK WASTE MANAGEMENT / LIVESTOCK FARM MANAGEMENT
Livestock/animal Waste management simply refers to the processes and actions required to capture, store, treat and use manure that is in liquid, slurry or solid form, from its inception which is the farm animals to its final disposal.
It is important to manage livestock waste so as to provide essential crop nutrients, through proper analysis of the waste so that a producer knows exactly what they are applying to their land and crops. When using best management practices, animal waste is an extremely valuable resource that will produce a good crop.
Animal wastes which are taken out from the farm are classified into 3 types; solid, slurry and waste water. Solid wastes are treated by drying or composting. Dried wastes are used not only fertilizer but also as fuel for combustion to obtain energy.
Examples of livestock/animals wastes/manure include dairy shed effluent (containing urine, dung, wash water, residual milk, and waste feed), dairy manure, poultry litter (a mix of manure, water, spilled feed, feathers, and bedding material), renderings, and other wastes from livestock finishing operations.
Definition of terms;
Manure is organic matter that is used as organic fertilizer in agriculture. Most manure consists of animal feces, compost and green manure.
Animal manures/livestock waste are the solid, semisolid, and liquid by-products generated by animals grown to produce meat, milk, eggs, and other agricultural products for human use and consumption.
Compost or synthetic manure is a mass of rotted organic matter made from waste-plant residues.
Green manure is a cover crop specifically sown to fertilize the soil while still green
Methods of animal/livestock waste /livestock farm waste management
Animal waste management can be done in two ways; echo friendly and modern methods
The echo-friendly methods include;
The modern methods include;
Animal or livestock waste / Livestock farm waste management systems
Production – Its availability of the raw material/waste matter from animals and plants.
Collection – Its involves putting together or assembling of the raw matter/waste
Storage – The waste is then stored in waste ponds/waste storage structure/waste treatment lagoons.
Treatment– involves application of chemical and biological reaction taking place in stored animal waste.
Transfer – as a result of waste treatment the gasfuel extracted from the reaction is then transferred in storage cylinders or tanks for consumption.
Utilize – the biofuel/gasfuel is then used for cooking, heating and electricity generation.
Environmental
Economical
Social
Once livestock/animal waste management is not properly implemented and managed then there is possible negative impact on the environment. Such effects may include;
Uses of animal waste /livestock waste
Conclusion
In future, we could try to imagine what livestock production and waste management should be and what it may become in the following aspects;
