  • 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 ...

  • 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 ...

  • 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 ...

  • What is Classification and Working Principle of Flat Die Pellet Machine?

    Pellets made of wood (sawdust), straw, seaweed etc, fall under the so called 3 E system. (Economic, Efficient, Ecological.) By pelletizing such products you can benefit from your waste, saving you money. Pellet machine is also called pellet press machine, pellet making machine, pellet extruder, pellet granulator and so on. The letter “machine” can be replaced by the letter ...

  • 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 ...

  • 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 ...

  • 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, ...

  • The number one thing each of us can do to protect biodiversity

    Reducing our consumption of animal products can go a long way toward conserving endangered habitat around the world. Agriculture expansion is the leading driver of natural habitat loss worldwide. However, most of this growth is not to produce vegetables, fruits or grains to be eaten by people. Ecosystems are destroyed overwhelmingly to feed livestock. Livestock production ...

  • 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 ...
