  • Case study - I am satisfied

    Urs Berger from Switzerland is an experienced pig farmer and he and his family is the second generation on the 250 acres farm in the village Oberbottigen. In 2013 he installed the DACS ventilation system in a new pig house - housing 1000 pigs for fattening. In the new house the pigs have access to an outdoor enclosure. Nevertheless they often choose to stay indoor - thanks to the very efficient ...

  • 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 ...

  • Main Applications of Truck Mounted ULV Fogger

    A fogger is a machine which distributes chemicals such as insecticide or disinfectant into an area by means of a fine spray for killing insects and other arthropods. They are often used by consumers as a low-cost alternative to professional pest control services. The number of fogger needed for pest control depends on the size of the space needed to treat. There are different types of ...

  • 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 ...

  • How the wild rabbit became domesticated

    An international collaboration involving INRA research scientists has evidenced the impact of domestication of the rabbit on its genetic heritage, thanks to sequencing of its genome. In particular, the scientists have shown that the genes controlling brain and neuronal development were specifically targeted by the domestication process. These results, published on 29 August 2014 in Science, help ...

  • 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 ...

  • 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 ...

  • Manure Compost A New Cash Crop

    A growing number of livestock producers are discovering manure compost as a new cash crop. When Mark Meyer refers to the “magic” at New Day Farms, he isn’t referring  to  the  liquid  egg  products  generated  by more than 2.5 million laying hens. Rather, Meyer, the environmental manager  at the Ohio facility, is talking about the ...

  • 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 ...

  • CH#1115 - Small Holder Piggery Problems

    Waste Type: Pig Manure Article: After 20 yrs with SAA, Mark Tutton, a qualified aircraft engineer, licenced to maintain Jumbos and having being stationed around SA and Mauritius decided to retire from the rat race. A few years before leaving he had purchased a small holding near Benoni where he bought [fattened] and sold goats & sheep. He came from a farming family, and, when he was ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...
