  • Reducing the Environmental Impact of Cows` Waste

    No disrespect to cows, but they produce a lot of gas. And while farmers may be unfazed by the smell, the gas is methane, one of the most potent greenhouse gases. Across the globe, livestock spew 14.5 percent of all greenhouse gases (methane, carbon dioxide, nitrous oxide and fluorinated gases) released in the environment, and over half that comes specifically from cows, according to a United ...

  • Analysis and dissipation of the antiparasitic agent ivermectin in cattle dung under different field conditions

    Cattle treated with the veterinary parasiticide ivermectin (IVM) fecally excrete residues. Here we report the exposition and dissipation characteristics of these residues in dung of IVM‐treated cattle, and in soil beneath this dung, on pastures including Canada, France, Switzerland, and The Netherlands. Residues were quantified for dung collected from cattle after 3, 7, 14, and 28 d post‐ ...

  • A four‐country ring test of nontarget effects of ivermectin residues on the function of coprophilous communities of arthropods in breaking down livestock dung

    By degrading the dung of livestock that graze on pastures, coprophilous arthropods accelerate the cycling of nutrients to maintain pasture quality. Many veterinary medicinal products, such as ivermectin, are excreted unchanged in the dung of treated livestock. These residues can be insecticidal and may reduce the function (i.e., dung‐degradation) of the coprophilous community. In the present ...
