  • 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 ...

  • Environmental and Economic Perspectives of Milk Production in Feedlot and Grazing Systems

    Abstract Dairy production systems involve large inputs and large outputs. In environmental and economic terms, this means dairying is potentially a large consumer of natural resources and a generator of large amounts of pollutants and waste as green house gases (GHG) and manure. To ensure a sustainable milk production system; it becomes important to understand the environmental and ...

  • The water footprint of soy milk and soy burger and equivalent animal products

    As all human water use is ultimately linked to final consumption, it is interesting to know the specific water consumption and pollution behind various consumer goods, particularly for goods that are waterintensive, such as foodstuffs. The objective of this study is to quantify the water footprints of soy milk and soy burger and compare them with the water footprints of equivalent animal products ...

  • Understanding the Fat in your Milk Replacer

    Fat digestion in the young calf Commercial milk replacers are often compared and evaluated based on the percentage of protein and fat on the label.  Discussion rarely delves into what makes up the components of fat and its effects on digestion, absorption or growth.  Fats are comprised of short chain, medium chain and long chain fatty acids.  The length of the chain is ...

  • Greenhouse gas, animal performance, and bacterial population structure responses to dietary monensin fed to dairy cows

    Received for publication January 27, 2009. The present study investigated the effects of a feed additive and rumen microbial modifier, monensin sodium (monensin), on selected variables in lactating dairy cows. Monensin fed cows (MON, 600 mg d–1) were compared with untreated control cows (CON, 0 mg d–1) with respect to the effects of monensin on the production of three greenhouse gases (GHG), ...

  • Application of artificial neural network to model the energy output of dairy farms in Iran

    An artificial neural network (ANN) model was developed to assess the energy input–output prediction in dairy farms of Iran. Data used were culled from 50 randomly selected farms using face to face questionnaire approach. The energy input–output analysis was carried out for the parameters of ANN model. Based on performance measures, single hidden layers with 16 neurons in the hidden ...

  • 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 ...

  • Farm digesters for small dairies in Vermont

    THROUGH its award-winning Cow Power program, Central Vermont Public Service (CVPS), a Vermont utility headquartered in the city of Rutland, is helping dairy farmers diversify their incomes by turning manure into electricity. The farmers process manure in anaerobic digesters to generate power, which CVPS customers voluntarily pay a premium to purchase. In addition to income from electricity sales, ...

  • Reuse of dairy lagoon wastewater through SDI in forage crops

    Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of ...

  • Dairy Digester Opens Doors On Maryland Farm

    Kilby Inc., a 600-cow dairy operation located in Colora, Maryland, has the only operational commercial anaerobic digestion (AD) system in the state. In 2009, Kilby Inc. (the dairy farm and milk production business) began construction of a covered lagoon digester, which started operating in March 2011. The digester input consists of flushed cow manure (98% by volume) and food waste (2%), including ...

  • Building consumer trust in eco-claims

    As public awareness of climate change increases, we see business and government beginning to rise to the challenge by changing the type of solutions available throughout the market. Businesses are reducing their environmental footprints and promoting their green claims on product labels and through retail channels. But how do consumers know which ‘green’ claims to trust? What should business ...

  • The significance of thyroid cancer in reactor safety assessment

    The risk of thyroid cancer from reactor accidents has long been a salient factor in the analysis of nuclear reactor safety. This risk arises largely from the abundance of iodine-131 in the fission product inventory. Iodine disperses widely if released into the atmosphere and could enter the human food-chain, particularly through consumption of contaminated cows' milk. Iodine entering the human ...

  • Lots of firsts at this year`s edition

    There will be a whole lot of firsts when the 2010 edition of Canada's Outdoor Farm Show begins Tuesday. The IMUS™ biogas machine arrived last Wednesday morning from Alberta via transport truck, said Lorie Jocius, president of Canada's Outdoor Shows Ltd. "It's the first time a mobile anaerobic digester has been moved across the country," she said. The machine arrived already ...

  • Industry Takes Shape: Why Digesters Make Dollar Sense Now

     THIRTY years ago, when I was a college student studying ways to convert manure to electricity, we speculated that the 1970s would be the decade of the innovators, the 1980s for the launch of operating projects, and the 1990s when the mainstream adopted the technology. Now I think our predictions for the mainstream were ten to 15 years premature — but it is happening! During the 1990s, the ...

  • Anaerobic Digestion at Dairy Farms

    The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites. The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of ...

  • Renewables Make Progress on Many Fronts: Grass Roots Ethanoll from Field Waste

    Progress in community digesters will bring fresh jobs and local control back to farm country - plus offering answers for global warming. FROM THE MIDWEST where native grasses, field waste and wood chips are fueling new biorefineries that are locally-owned to the Northwest where some 50 million gallons of raw manure are producing electricity and dried bedding, community digesters and on-farm ...

  • How to produce good quality silage

    We all know the benefits of good silage. But are we really all doing everything we can to produce good quality silage? If you want to help protect your farm business against ups and downs in milk or meat prices, or feed costs, there’s a straightforward approach: maximise the amount of milk or meat produced from home-grown forage. It is arguably one of a livestock farm’s biggest ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...
