Explore all the information onSwine manure treatment
Swine manure (SM) is a plentiful and readily available farm waste that is commonly managed using traditional disposal methods, including agricultural application, lagoon storage, anaerobic digestion or direct incineration.
If mishandled, however, swine manure can contaminate surface and ground waters. Proper storage, handling and application of manure from pork production operations can protect water resources and increase profits for animal and crop enterprises.
Pork producers select a manure handling system based on factors such as location, the size, type and use of their cropland, the number of animals, and the type of animal housing. Many options relate to the type of housing system - pasture, dry lot, and enclosed.
With all systems, divert rain and snowmelt runoff away from the manure handling system. Install gutters to direct roof runoff to a ditch or other diversion. Keep uncontaminated surface water away from lots, settling facilities, infiltration channels, outdoor storages, and animal traffic lanes. Channel contaminated lot runoff to adequate treatment, storage, and application systems.
Introduction An Giang province has an agriculture- based economy. Pig production is considered one of the most important livestock activities in the province, mainly by smallholders. Recently, pig production has rapidly increased to supply the demand for meat. The increased concentration of intensive livestock is associated with the pollution and the pig waste becoming a serious environmental hazard. Livestock waste...
Introduction Odor from swine production systems is generated at three primary sources: animal housing, manure storage and during land application. This publication addresses controlling odors during land application of swine manure. Unlike odor generation from animal housing and manure storage, which are usually continuous in nature, odor from manure application is an "event-based" occurrence. The majority of odor...
Manure Management, Odor and Diseases Control Livestock Producers are going through much criticism for creating pollution and diseases problems. In the mean time farmers having production problems (costly manure handling, high energy consumption, medicine cost and most important barn is not save working place). One of the long-standing and costly problems of handling manure has been the absence...
The influence of intensive agriculture on both the environment at large and within livestock buildings is receiving the highest priority in research programmes. In many cases emissions are a limiting factor for the location and operation of animal production facilities throughout the world. Odours from livestock production are perplexing mixtures of chemical compounds and have become a severe social problem in many countries. Some of the compounds will have health damaging effects as...
One of the costs of running a farm can include buying nitrogen in the form of anhydrous ammonia to fertilize crops. But there are other agricultural costs associated with nitrogen, especially when the nitrogen in livestock waste produces pungent—and potentially harmful—ammonia emissions.
But on June 20, 2011, Agricultural Research Service soil scientists Matias Vanotti and Ariel...
Phosphorus-based nutrient management regulations increase the amount of land required to dispose of manure and will have a detrimental effect on pig farm profitability in areas of intensive animal production. Decreasing the phosphorus content of manure through nutrition with phytase is a powerful and cost-effective approach to reduce the amount of land required for pig production and therefore reduce the cost of manure disposal. ...

Charles Shaphiro, (University of Nebraska) gave a lecture at ALVEC 2010 about the use of swine manure in agriculture. ...
Several studies exploring composting as an alternative to direct land application of swine manure were conducted. The primary objective of these studies was to develop composting procedures for feasible use on Illinois farms.
Summary
Composting manure is a practical, economical, environmentally safe way for pork producers to co-exist...
Researchers with the University of Manitoba are confident a chemical process used to remove struvite from municipal waste streams for sale as phosphorus fertilizer can be applied to livestock manure.
Last September researchers with University of Manitoba launched a two year project aimed at recovering magnesium ammonium phosphate, or struvite, from raw liquid or anaerobically digested hog manure for use as phosphorus fertilizer.
Biosystems engineering professor Dr. Nazim...
A researcher with the University of Manitoba says the management of phosphorus applications to crop land will vary according to the source of the nutrient.
The Manitoba government has imposed strict limits on phosphorus applications to reduce the risk of excess amounts ending up in waterways.
Dr. Don Flaten, a soil fertility researcher with the University of Manitoba and chair of the National Centre for Livestock and the Environment, says the source as well as rate, placement...
New and expanding swine production facilities in North Carolina are required to use manure management systems that meet the strictest environmental performance standards in the nation. Fortunately, Agricultural Research Service (ARS) scientists and cooperators have developed a system that exceeds state benchmarks for controlling pollutants from swine farms.
Soil scientists Matias Vanotti and Ariel Szogi worked with Super Soil Systems...
Sulphurous compounds are the main source of the obnoxious smells from pig farms. Scientists from the Faculty of Agricultural Sciences are focusing on these substances in an attempt to remove them and thus probably much of the odour currently emitted from pig houses. Neighbours to pig farms may breathe fresher air in the future. Scientists from the Faculty of Agricultural Sciences and their collaborators have been given a sum of money from the Strategic Research...
Traditionally, pigs were fed household waste, while their manure was used as a fertilizer for crops. Although it may not have been realized at the time, this system resulted in a continuous reuse of minerals such as phosphorus, and thus it prevented environmental prob-lems with these minerals.
In modern production practices, where feedstuffs are brought in from afar, this cycle is often broken. Minerals are allowed to accumulate somewhere in the swine production system-for example,...
Researchers at North Carolina State University have found that a tiny aquatic plant can be used to clean up animal waste at industrial hog farms and potentially be part of the answer for the global energy crisis. Their research shows that growing duckweed on hog wastewater can produce five to six times more starch per acre than corn, according to researcher Dr. Jay Cheng. This means that ethanol production using duckweed could be "faster and cheaper than from corn," says fellow...
An engineering study undertaken on behalf of the Manitoba Rural Adaptation Council shows gravity offers a potentially low cost solution to managing the phosphorus in liquid hog manure. A research team working in partnership with the Niverville, Manitoba based Puratone Corporation conducted three trials during the summer of 2008 to determine whether the solid and liquid factions of hog manure could be separated by simply pumping the manure into a storage tank and allowing the...
Ammonia and volatile organic compounds are major contributors to air quality problems associated with swine production. Odorants result from the fermentative degradation of carbohydrates, fats, and proteins in the large intestine and manure of swine and, therefore, can be manipulated by diet composition (Hobbs, et al., 1996; Sutton, et al., 1999). However, individual differences in odor perception make it difficult to demonstrate odor abatement strategies or validate odor nuisance problems...
One of agriculture's most versatile crops could one day play a role in combating climate change, Purdue University research shows.
In addition to using soybeans in beverages, biofuel, lip balm, crayons, candles and a host of other products, Purdue agricultural engineers Al Heber and Jiqin Ni found that soybean oil reduces greenhouse gas emissions when sprayed inside swine finishing barns.
Heber and Ni led a team of Purdue and University of Missouri researchers in the yearlong...
Water conservation is a growing concern in intensive swine operations (ISOs) for both financial and environmental reasons. The water usage of a grower-finisher room in an ISO was measured using dry and wet/dry feeders. The major source and sink of water was at the drinker and in the manure, respectively. In addition, water disappearance and manure volume were reduced from 9.3 to 6.2 and from 8.9 to 5.4 kg water/pigday, respectively, when wet/dry feeders were used in place of dry...
Research underway at the National Centre for Livestock and the Environment suggests higher manure handling and labour costs in straw based swine housing may be offset by reduced veterinary costs and lower culling rates.
Researchers with the University of Manitoba's Faculty of Agricultural and Food Sciences have been comparing sows raised in conventional slatted floor systems to those raised in groups housed on straw since 2006.
As well as evaluating differences in the manure...
