  • CORNucopia of Opportunity in the Heartland: Or Just More Feed for the Political Cattle?

    We now live in a carbon constrained world. Fears of human induced climate change are bringing about changes in government, corporate and consumer behaviors. Investments in renewable energy are increasing, corporations are greening everything from their supply chain to their vehicle fleet, and consumers are seeking to minimize their ecologic footprint as well. Are some of our greening efforts ...

  • The Ins and Outs of Cattle Nutrition

    They say, “You are what you eat.” What goes in and out of our bodies is obviously important for our general health and maintenance. Well, the same holds true for our cattle as well, but with one main difference: Where we only have one stomach to worry about, they have four! Cattle are animals technically classified as ruminants, a distinction that includes sheep, ...

  • Seasonal Changes in Airborne Fungi and Bacteria at a Dairy Cattle Concentrated Animal Feeding Operation in the Southwest United States

    The objective of this study was to evaluate a dairy located in the arid southwest United States to determine the concentrations and seasonal variation of airborne fungi and bacteria and to determine the percentage of antibiotic resistant Staphylococcus aureus. The authors used two-stage ambient air sampling systems to measure the culturable airborne fungal organisms and bacteria on a monthly ...

  • Research highlights cattle emissions reduction opportunity

    Researchers in Denmark have measured the quantities of greenhouse gases in the breath of dairy cows and demonstrated a heritable variability between individual animals. “This means that we have an opportunity to select for breeding those individuals which will produce offspring that generate less methane,” says Dr Jan Lassen who led the research project on individual methane ...

  • Nutrient export in run-off from an in-field cattle overwintering site in East-Central Saskatchewan

    Wintering cattle directly in the field creates potential concerns with water quality, as nutrients added from urine and fecal material over the winter can end up in runoff water, ground water and soil. In 2008/2009 an experiment was conducted to observe the effect of in-field winter feeding of cows on the nutrients in spring snowmelt run-off water. Low temperatures give little opportunity for ...

  • US feedlots and slaughterhouses: bounding industrial ecology with the extreme case

    The potential contribution of Industrial Ecology (IE) to sustainable development, though immense, remains elusive. This is due to the field boundaries whose demarcation lacks specificity. To address the challenge of boundary definition, an agro-industrial complex, the US Cattle Feedlot-Slaughterhouse System (CFSS), has been chosen to illustrate and provoke a discussion about where those ...

  • Beef Farmer Spring 2017 `Trace elements are key to growth rates`

    Iodine has a direct impact on growth rates as it is incorporated into the thyroid hormones which control metabolism, promoting efficient live weight gain. Annie Williams, Animal Scientist with Agrimin says that many beef units fall short on achieving optimum growth rates because animals do not receive adequate levels of trace elements at grass. She says that with increased feed costs, many ...

  • Fishing for a Solution

    As writer Rowan Jacobsen explores in our recent feature “Has Meat Met Its Match?,” animal agriculture’s hefty environmental footprint is creating interest in exploring ways to meet humans’ growing appetite for animal protein that extend beyond beef, chicken and pork. In some places, that ...

  • 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 ...

  • Spent grain dewatering

    1. Back ground: Firms that produce alcoholic beverages from grain are an important market for dewatering Powerful Belt Press. The industry firms consist mostly of beer brewers and distilleries. Their raw materials are barley, corn, wheat, rice, and other grains. They all produce a common by-product: spent grain. Spent grain is the name given to material left after the grain is fermented and the ...

  • Getting kids to eat green

    Kids love food, but it's not always the tasty treats that are good for them or the earth. Fatty, sugary, salty and processed foods generally have more of an environmental impact than eats of the fresh, locally produced variety. It is therefore important to teach them what is healthy to eat, and how and where their food comes from. This will help them to understand the impact of the food they eat, ...

  • Moving Up the Food Chain

    For most of the time that human beings have walked the earth, we lived as hunter-gatherers. The share of the human diet that came from hunting versus gathering varied with geographic location, hunting skills, and the season of the year. During the northern hemisphere winter, for instance, when there was little food to gather, people there depended heavily on hunting for survival. Our long history ...

  • When population growth and resource availability collide

    As land and water become scarce, competition for these vital resources intensifies within societies, particularly between the wealthy and those who are poor and dispossessed. The shrinkage of life-supporting resources per person that comes with population growth is threatening to drop the living standards of millions of people below the survival level, leading to potentially unmanageable social ...

  • Does one of the world’s most abundant animals need protection from our appetite?

    As demand grows and habitat disappears, scientists ponder tighter controls on the Antarctic krill harvest. Barely longer than your thumb, weighing under an ounce and nearly translucent, delicate crustaceans known as krill are vital to ocean ecosystems around the world. In the waters that encircle Antarctica, krill are an essential food source for penguins, baleen and blue ...

  • CRISPR is coming to agriculture — with big implications for food, farmers, consumers and nature

    Gene editing offers dramatic advances in speed, scope and scale of genetic improvement. It also offers an opportunity for more nuanced GMO governance. Very few technologies truly merit the epithet “game changer” — but a new genetic engineering tool known as CRISPR-Cas9 is one of them. Since we first developed the ability to alter the genetic material inside a plant or animal in ...

  • Transgenic fish are ready for us. Are we ready for them?

    After decades of regulatory and legal challenges, AquaBounty aims to bring genetically engineered salmon to U.S. and Canadian markets next year. On a hill above the cold waters around Prince Edward Island, technicians painstakingly create fertilized Atlantic salmon eggs that include growth-enhancing DNA from two other fish species. The eggs will be shipped to ponds in the high rainforest of ...

  • Zimbabwe`s New Farmers Fail to Deliver

    HARARE, Zimbabwe, (ENS) - Six years after President Robert Mugabe sanctioned violent invasions of Zimbabwe's commercial farmland - mostly but not entirely white owned - by landless peasants, the facts show that the so-called new farmers have failed dramatically to produce crops to feed their countrymen. The poor peasants who led the invasions, at the behest of Mugabe, have ...
