  • Sunset Colony Study

    “We have had the Silver Bullet AG300 unit now for ten months with great measurable results. This system is currently on our water line, treating the swine gestation, farrowing and nursery. The unit can treat 75,000 gallons of water per day and will be injected into our large water tank to treat our swine gestation, farrowing, nursery, finishers and dairy. What I like about the Silver Bullet ...

  • Catastrophic cost of Foot and Mouth Disease

    Foot and Mouth disease has never completely disappeared. Although it has been almost 20 years since the last major outbreak of Foot and Mouth disease in the UK, which cost the industry more than £8 Billion, it does not mean that the disease is not still a very real risk to the economy. ...

  • Testimonial Hans Liniger, Switzerland: Animal welfare is the farmer`s profit

    Hans Liniger from Bernischen Lanzenhäusern in Switzerland has been a farm construction consultant for pig farmers for 35 years. Experience tells him even the smallest mistake in the planning process can have a significant negative impact on the welfare of the pigs. Hans Liniger from Bernischen Lanzenhäusern in Switzerland has been a farm construction consultant for pig farmers for 35 ...

  • Testimonial Mr. Berger from Switzerland: no smell of pigs in the DACS house

    Urs Berger is the second generation on his 250 acres farm in the village Oberbottigen in Switzerland. In 2013 he installed a DACS ventilation system in a new 1000 finisher unit. The pigs have access to an outdoor area. Nevertheless, they often choose to stay indoor - thanks to the very constant movement of preheated air in the house. Ventilation without draught With the DACS ...

  • Enhancing growth of Chlamydomonas reinhardtii and nutrient removal in diluted primary piggery wastewater by elevated CO2 supply

    The coupling of primary piggery wastewater as a culture medium with elevated CO2 aeration is thought to be an economically feasible option for the cultivation of microalgae. However, little information is available regarding the photosynthetic characteristics of microalgae and nutrient removal from wastewater at different CO2 concentrations. It was found that elevated CO2 ...

  • How ILI Pig Tracking can be dangerous if done incorrectly

    Pipeline pigs are tools that are inserted into a pipeline and pushed along the pipeline by the product flowing through the pipeline. There are many different types of ILI tools. Some are used to clean the pipeline, while others are used to inspect the pipeline for deformities or corrosion damage. Some are even used to purge different products in a multi-product pipeline. Inline inspection (ILI) ...

  • Lowara pumps drive livestock operations

    Animal output processed for safe disposal, reuse and renewable energy Xylem scope Xylem Lowara have installed several different types of pumps in this process cycle. Ranging from the DLV submersible pump fitted with Vortex impeller used in the pressurization of wastewater obtained from the separation of the digestate. Various high efficiency e-range pumps ...

  • Cultivation of an Arthrospira platensis with digested piggery wastewater

    An Arthrospira platensis strain ZJWST-S1 was isolated in Jiaxing City, China, which proved able to proliferate quickly in undiluted digested piggery wastewater (DPW), and the protein content in the algal biomass was high. Single factor experiments showed that the strain was able to quickly grow in a Zarrouk medium as the dosage of sodium bicarbonate, nitrate-nitrogen and phosphate-phosphorus ...

  • Pretreatment of piggery wastewater by a stable constructed microbial consortium for improving the methane production

    A stable aerobic microbial consortium, established by successive subcultivation, was employed to solubilize the solid organic fraction in swine wastewater. In the 30 days' successive biological pretreatments, 30–38% of volatile solids and 19–28% total solids in raw slurry were solubilized after 10 hours at 37 °C. Meanwhile, soluble chemical oxygen demand ...

  • Characterization of polyhydroxyalkanoate-producing bacteria isolated from sludge of commercial pig farms for producing methyl esters

    The objectives of this work were to isolate and characterize the polyhydroxyalkanoate (PHA) producing bacteria in enriched piggery sludge and make methyl esters from PHA for industrial applications. The strain ECAe24 isolated from piggery sludge with the highest PHA production was selected to produce PHA and then methyl ester by trans-esterification using glucose as substrate under mesophilic ...

  • The viability of treated piggery wastewater for reuse in agricultural irrigation

    Background The swine production is a very important economic matter, occupying prominent position in the worldwide market. However, it appears as the greater impacting activity for the water resources. Researches point a swine manure production of 105.6 million m3/year in Brazil, which resulted in a piggery wastewater rich in solids, nutrients, heavy metals, and pathogens. Moreover, ...

  • Design of an integrated piggery system with recycled water, biomass production and water purification by vermiculture, macrophyte ponds and constructed wetlands

    Since 2001 the swine experimental station of Guernévez has studied biological treatment plants for nutrient recovery and water recycling, suited to the fresh liquid manure coming out of flushing systems. An integrated system with continuous recycling was set up in 2007, associated with a piggery of 30 pregnant sows. It includes a screen, a vermifilter, and macrophyte ponds alternating with ...

  • Image-based measurement of alveoli volume expansion in an animal model of a diseased lung

    This research aims to improve ventilation protocols in critical care by using appropriate computer models that take into account the essential lung mechanics. This paper automatically tracks the boundary of individual or groups of alveoli, and converts this into a pressure volume curve for three different types of alveoli. Schiller et al. investigate the inflation and deflation of alveoli in a ...

  • Methane and carbon dioxide emission from two pig finishing barns

    Received for publication July 22, 2007. Agricultural activities are an important source of greenhouse gases. However, comprehensive, long-term, and high-quality measurement data of these gases are lacking. This article presents a field study of CH4 and CO2 emission from two 1100-head mechanically ventilated pig (Sus scrofa) finishing barns (B1 and B2) with shallow manure flushing systems and ...
