  • Open-air windrows for winter disposal of frozen cattle mortalities: effects of ambient temperature and mortality layering

    After imposition of fees for disposal of cattle carcasses by the rendering industry, on-farm methods of mortality disposal are being investigated. Three open-air mortality compost windrows were constructed in January (JAN) and February (FEB) of 2004 in the cold, semiarid climate of southern Alberta, Canada. Windrow A included a base of barley straw a minimum of 46 cm thick, a layer of cattle ...

  • Trenbolone causes mortality and altered sexual differentiation in Xenopus tropicalis during larval development

    Trenbolone is an androgen agonist used in cattle production and has been measured in aquatic systems associated with concentrated animal‐feeding operations. In this study, the authors characterized the effects of aqueous exposure to 17β‐trenbolone during larval Xenopus tropicalis development. Trenbolone exposure resulted in increased mortality of post‐Nieuwkoop–Faber stage 58 tadpoles at ...

  • Influence of some biological wastes and their combination on growth and reproduction potential of earthworm, Eisenia fetida and their effect on plant growth

    Effect on growth and reproduction potential of animal wastes viz., cow, goat, horse and a domestic waste (used tea dust) and their combinations to the earthworm, Eisenia fetida, was studied under laboratory conditions. The effect of above on growth aspects of Bhendi crop was compared with the normal compost individually under green house conditions. The effects on growth were assessed for ten ...

  • Variations in lethal and sublethal effects of cypermethrin among aquatic stages and species of anuran amphibians

    Unpredicted variation in levels of risk to organisms to xenobiotics can be observed, despite the use model species to predict the effects of chemicals in the environment. Physiological and morphological differences between species and life stages may lead to differences in sensitivity, while seasonal and spatial variation in pesticide concentrations may affect the level of risk faced by ...

  • A biosecure composting system for disposal of cattle carcasses and manure following infectious disease outbreak

    Received for publication April 11, 2008. During outbreaks of infectious animal diseases, composting may be an effective method of disposing of mortalities and potentially contaminated manure. Duplicate biosecure structures containing 16 cattle (Bos taurus) mortalities (343 kg average weight) were constructed with carcasses placed on a 40-cm straw layer and overlaid with 160 cm of feedlot manure. ...

  • A Review of Enteric Outbreaks in Child Care Centers: Effective Infection Control Recommendations

    Child care environments facilitate the spread of enteric infections because of diapering, confined spaces, and children’s unhygienic habits. This study reviews documented outbreaks of enteric illness in daycare centers (DCCs) to identify infectious agents, modes of transmission, morbidity/mortality, ages, secondary cases, and practices found effective by investigators. A systematic review of the ...

  • Imposex and novel mechanisms of reproductive failure induced by tributyltin (TBT) in the freshwater snail Pomacea canaliculata

    The effects of TBT on mortality and reproduction were studied in this invasive snail. The nominal fifty percent lethal concentration (LC50) was 9 µg TBT/L, after 28 days. The nominal ‘no observed effect on lethality concentration’ (NOECL) was 6 µg TBT/L after the same period. Male‐female couples and females that had been group‐mated but were isolated from males during the experiment (isolated ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...

  • Pragmatic farm composters forge new path to resource recovery

    AG CHOICE is an on-farm composting operation located in the scenic countryside of Andover, New Jersey. On the drive to tour their site, it was astounding just how much of New Jersey, our most densely populated state, is still rural. Jay and Jill Fischer operate the two-year-old facility, which is one of a kind in New Jersey. Jay also owns and operates a sawmill in the area, and it was while ...

  • Cost-Benefit Analyses: Exploring the Economics of On-Farm Composting

    When exploring the merits of on-farm composting, the question most often raised is: What are the economics? How do the savings or revenues from on-farm composting compare to the costs? Of course, the answer is the ever present “it depends.” Expenses, resources, revenue opportunities, environmental constraints and circumstances vary greatly from one farm to the next. Most people would agree that ...

  • Composting Advances in Oregon and Washington

    Over the years, different forces have served as drivers to help grow the composting industry. For example, in the late 1980s and early 1990s, it was the perceived landfill crisis that led to state bans on disposal of yard trimmings. Composting also has benefitted from a push to meet recycling goals, which has prompted states and local governments to go beyond yard trimmings and into such ...
