Swine 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 Swine raising has changed considerably in the last 30 years with an increase in intensive production systems. Whereas intensive systems minimize production costs, the high animal densities can pose impacts to environments that have low soil absorption capacity (Kunz et al., 2009a; Vanotti et al., 2009). Thus, confined animal feeding operations (CAFOs) while reducing the production costs can increase the use of water and the environmental impacts associated with the...

Introduction The application and distribution of manure on croplands is influenced by the relief and geographical position of farms and the size of the area, being limited to certain times of the year depending on weather conditions (Hodgson et al., 2016; Broetto & Meinerz, 2017). Therefore, until its disposal, manure needs to be kept in a suitable storage structure and to be correctly managed, which requires understanding the basic types of bacteria present in it. According...

Introduction: Porcine Epidemic Diarrhea (PED) virus is a major enteric swine disease of economic significant in many Asia country and PED was first recognized in late April of 2013 in USA. According to some research, PED virus survived in manure slurry for 28 days at 4℃ and possible longer. The main purpose of this study is to investigate the time to inactivate of the PED virus in manure slurry on farm. Materials and...

Introduction: Straw is one of the most effective routing materials to reduce tail biting in pigs. A so called foraging-tower (FT) enables to provide only small quantities of straw compatible with liquid manure systems. The focus was on the effect of providing straw by FT for the prevention of tail biting in tail docked pigs. Materials and Methods: The study was conducted from June 2013 to August 2014 in a conventional farrow to finish herd in Germany, which...

INTRODUCTION The selection of animals for improved production traits has been, for a long time, the major driver of pig breeding (1, 2). More recently, because of the increasing concern with environment, new selection criteria have been explored, such as nitrogen (N) or phosphorus (P) excretion, which are related to both feed efficiency and environmental impact (3). Residual feed intake (RFI) was also proposed as a possible selection criterion to simultaneously improve feed...

INTRODUCTION The practice of fertilization, when necessary, can result in a yield up to three times greater than when not adopting the practice (IFDC, 2012) and is responsible for preserving 67 million hectares in Brazil (FAO, 2013). Such activity helps explain Brazil’s position as the world’s fourth largest consumer of mineral fertilizers; however, 75 % of these products are imported (ANDA, 2013), which places undo risk on agribusinesses, which account for 27 % of...

INTRODUCTION In the intensive animal agriculture system, swine production faces many challenges related to the management of manure. These may include handling and proper storage of manure, odor production, and the accumulation of manure solids in the pen. The production of noxious gases and accumulation of solids in the pen are due to inadequate microbial decomposition of manure (Davis et al., 2008). Mal odor of manure is an acute environmental problem, because they cause...

I'm glad I've come to an active forum.
I found that there were not many posts on pig manure treatment in this forum.
So I edited this post, and I'm interested in discussing how to deal with your pig manure.
There are 5000 pigs on my farm. The pig manure problem has been bothering me for a long time. I am thinking of a good way to solve it....

Introduction Confined swine (Sus scrofa L.) production generates large volumes of wastewater typically stored and treated in anaerobic lagoons. These lagoons usually require a sludge maintenance plan consisting of regular sludge removal followed by land application (Barker, 1996). Anaerobic lagoon liquid and sludge are both rich in nutrients, particularly nitrogen (N), phosphorus (P), copper (Cu), and zinc (Zn). However, P can be the limiting nutrient on land...

INTRODUCTION As mentioned in CERVI et al. (2010), the expansion of pig farming has resulted in a significant increase in the volume of produced waste, increasing the risks of environmental contamination. The swine excrement shows great pollution potential. Thus, this residue must be handled properly, or may cause serious impacts to the ecosystem. In the definition of KUMAREZAN et al. (2009), residue is an energy resource disposed in an inappropriate location; however, this could...

Control methods are needed to abate NH3 losses from swine anaerobic lagoons to reduce the contribution of confined swine operations to air pollution. In a 15-mo meso-scale column study, we evaluated the effect of manure pretreatment on water quality, reduction of N losses, and sludge accumulation in swine lagoons using (i) enhanced solid–liquid separation with polymer (SS) and (ii) solid–liquid separation plus biological N treatment using nitrification–denitrification (SS +...

Large volumes of wastewater from confined pig production are stored in anaerobic lagoons. Control methods are needed to reduce air pollution by foul odors released from these lagoons. In a pilot-scale experiment, we evaluated the effect of pig wastewater pre-treatment on reducing the concentration of selected malodor compounds in lagoons receiving liquid from: (1) flocculant enhanced solid–liquid separation (SS), and (2) solid–liquid separation plus biological N treatment using...

Does It Make a Difference If a New Pig Barn is Built In an Area With Existing Barns?
A model, called the Community Assessment Model for Odor Dispersion (CAM), was developed to predict receptor odor exposure from multiple swine production sources. The intended use of CAM was to provide a tool for evaluating the odor exposure to receptors in a community when siting new swine production systems and how a change in odor control technology alters the odor exposure to...

Introduction Livestock production in confinement facilities results in gas emissions such as ammonia (NH 3 ), methane (CH 4 ), nitrous oxide (N 2 O) and carbon dioxide (CO 2 ). In pig production, NH 3 , CH 4 and N 2 O are products of manure decomposition while CO 2 is primarily a product of animal metabolism. Ammonium (NH 4 + ), under acidic or neutral pH conditions or NH 3 at...

INTRODUCTION Currently the potential impact of manure on the environment represents one of the world agriculture's major challenges. Once dominated by many small operations as part of traditional crop-livestock farms, livestock production has become highly concentrated in large operations. This development has separated animal production from crop production. Thus, the amount of manure produced often exceeds local demand for use as...

Introduction Water is the nutrient that is required in the largest quantity by swine. Compared to the other nutrients supplied by feed, it is the most frequently misunderstood and mismanaged nutrient. While various sources recommend that water be available free choice, most fail to offer specific recommendations as to number of drinking spaces, drinker type, delivery rates of drinkers, or to specify quality parameters. In...

Pig producers would like to keep their costs down by supplementing livestock feed with dried distiller’s grains with solubles (DDGS) and other agricultural coproducts generated from biofuel production. But adding hard-to-digest fiber to livestock diets also increases the production of manure—never a good thing, especially when it...
