  • Lead and zinc content of cows' milk affected by varying traffic density

    This study was conducted to investigate the influence of vehicle emissions on zinc and lead content of cow's milk, grazing at 15 different locations near to roadsides in Sakarya, Turkey. The results obtained for zinc were between 1262 μg kg−1 and 6566 μg kg−1. An acceptable range of zinc content from various sides confirmed the absence of possible toxicological risks in this region. The lead ...

  • Effects of reducing dietary nitrogen on ammonia emissions from manure on the floor of a naturally ventilated free stall dairy barn at low (0–20°C) temperatures

    Received for publication December 30, 2008. This study was conducted to determine the potential for reducing ammonia (NH3) emissions from manure deposited on the floor of a naturally ventilated free stall barn by mid-lactation dairy cows fed reduced or normal N diets. Two crude protein (CP) diets (178 g kg–1 [high] and 159 g kg–1 [low] dry matter ), were used. The diets were fed to 48 Holstein ...

  • 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), ...

  • Impact of defoliation on corn forage quality

    Hail damage can be a serious problem on corn (Zea mays L.) grown for silage. The value of corn grown for silage is a function of both the yield and quality of the forage produced. An improved understanding of the effects of defoliation on forage quality would improve the ability of agronomists, farmers, and crop insurance adjusters to assess the economic impact of hail damage to corn harvested ...

  • Seed-applied insecticides inconsistently affect corn forage in continuous corn

    Western corn rootworm (Diabrotica virgifera virgifera Le Conte) is the major insect pest in the corn phase of a corn (Zea mays L.) silage–perennial forage rotation. Dairy producers may prefer seed-applied instead of soil-applied insecticides for rootworm control because of ease of use and additional control of some other soil insect pests. The objective of the 2-yr NY field study was to evaluate ...

  • The nutritional assessment of GMOs before commercialisation, how to approach a comprehensive assessment

    Using the in vitro gas production technique - which evaluate nutritive value of ruminants feeds - the fermentation kinetics of genetically modified (GM) corn and the gas production of GM soybean were respectively faster and lower compared to their respective conventional counterpart, although the chemical composition were not affect by the genetic modification. Concerning the fate of vegetable ...

  • Dietary cation–anion difference and tetany index of timothy forage fertilized with liquid swine manure

    Incidence of metabolic disorders increases when dairy cows (Bos taurus) are fed forages that have a high dietary cation-anion difference (DCAD) (>250 mmolc kg–1 dry matter, DM) or high grass tetany (GT) index (>2.2), both associated with high forage K concentration, often caused by applications of liquid swine manure (LSM). We determined how DCAD and GT index of timothy (Phleum pratense L.), ...

  • Effect of nitrogen application on yield and quality of silage corn after forage legume-grass

    Decomposition of forage legume-grass (FLG) sods after turnover will supply N to the next corn (Zea mays L.) crop. For optimum economic grain production typically a starter N application is sufficient. However, the impact of eliminating sidedress N on yield and quality of silage corn in the year after sod turnover (FYC) is not well documented and little is known about the effects of timing of sod ...

  • Growing demand for soybeans threatens Amazon rainforest

    Some 3,000 years ago, farmers in eastern China domesticated the soybean. In 1765, the first soybeans were planted in North America. Today the soybean occupies more U.S. cropland than wheat. And in Brazil, where it spread even more rapidly, the soybean is invading the Amazon rainforest. For close to two centuries after its introduction into the United States the soybean languished as a curiosity ...

  • Iceland: New poultry house for broiler production - Case Study

    There is a good reason why Iceland’s agriculture is dominated by animal husbandry: the island country in Northern Europe has a very unique nature, which is, however, also characterised by lava fields and a harsh climate. Only 1 % of the country’s area is suitable for cultivation, another 19.5 % can be used as pasture.  Poultry production is one branch of Iceland’s ...

  • Agriculture and Environment in EU-15 — the IRENA Indicator Report

    Background and purpose The IRENA operation (Indicator Reporting on the Integration of Environmental Concerns into Agriculture Policy) is a joint exercise between several Commission directorates-generals (DG Agriculture and Rural Development, DG Environment, Eurostat and DG Joint Research Centre, and the European Environment Agency (EEA) to develop agri-environmental indicators for monitoring the ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • How farm policy used to work

    In the period between the 1930s and 1992, farm bills generally instituted compensation policies that took the form of price supports. These policies were designed to manage the surplus production that resulted from centuries of developmental policies while allowing U.S. farmers the chance, with hard work and good management skills, to provide their family with a livelihood. Compensation policies ...

  • Can the World Feed China?

    By Lester R. Brown Overnight, China has become a leading world grain importer, set to buy a staggering 22 million tons in the 2013–14 trade year, according to the latest U.S. Department of Agriculture projections. As recently as 2006—just eight years ago—China had a grain surplus and was exporting 10 million tons. What caused this dramatic shift? It wasn’t until 20 years ...

  • 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 ...

  • Global Grain Stocks Drop Dangerously Low as 2012 Consumption Exceeded Production

    The world produced 2,241 million tons of grain in 2012, down 75 million tons or 3 percent from the 2011 record harvest. The drop was largely because of droughts that devastated several major crops—namely corn in the United States (the world’s largest crop) and wheat in Russia, Kazakhstan, Ukraine, and Australia. Each of these countries also is an important exporter. Global grain ...
