Nutrient accumulation below cattle feedlot pens in Kansas
Received for publication April 30, 2008. Waste excreted on cattle (Bos taurus) feedlot pens is a source of N and other nutrients that could potentially leach into soil and negatively impact local groundwater quality. Analyses of soil chemical and physical properties beneath active open air feedlot pens were conducted at four Kansas locations to determine nutrient accumulation. Results were ...

Effects of dried distillers` grains with solubles (wheat-based) in feedlot cattle diets on feces and manure composition
The use of dried distillers' grains with solubles (DDGS) in feedlot cattle (Bos taurus) diets is increasing as the bio-ethanol industry expands. This study investigated how wheat (Triticum aestivum L.) DDGS-based diets impact feedlot cattle nutrient and volatile fatty acid (VFA) excretion. Feedlot heifers were fed DDGS at 0 (Control) 20, 40, 60% or 60% + Ca (1% limestone) of dietary dry matter. ...

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 economic ...

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 ...

Three Steps to Manage Heat Stress in Beef Cattle
The full swing of summer will bring high temperatures, high humidity, and high chances of heat stress. Heat stress is a major concern in the beef industry, causing countless problems in cattle, such as a decrease in feed intake, diminished digestibility, and a significant negative impact on performance. High temperatures can cause cattle to reduce feed intake, which can negatively affect ...

Ammonia and hydrogen sulphide flux and dry deposition velocity estimates using vertical gradient method at a commercial beef cattle feedlot
Ammonia and hydrogen sulphide flux and dry deposition velocity were estimated using micrometeorological vertical gradient flux method at a commercial cattle feedyard of approximately 50,000 head of beef cattle and average 14.4 m²/head (150 ft²/head) stocking density. Ammonia-N and H2S-S loss had general diurnal patterns with the highest fluxes in daytime and lowest fluxes in nighttime that ...

A biosecure composting system for disposal of cattle carcasses and manure following infectious disease outbreak
Received for publication April 11, 2008. During outbreaks of infectious animal diseases, composting may be an effective method of disposing of mortalities and potentially contaminated manure. Duplicate biosecure structures containing 16 cattle (Bos taurus) mortalities (343 kg average weight) were constructed with carcasses placed on a 40-cm straw layer and overlaid with 160 cm of feedlot manure. ...

Phosphorus runoff is a big problem, but Florida is getting closer to a solution
Excess phosphorus runoff and emissions from urban areas and croplands, animal feedlots, sewage treatment plants, and combustion of fossil fuels has been blamed for the dead zone in the Gulf of Mexico, toxic algal blooms in Lake Erie and problems in numerous other lakes and rivers around the world. For years unwanted nutrients were also choking the Florida Everglades, but in a surprising ...

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 exploration is going underwater. Aquaculture, or fish farming, is the fastest growing ...

New study finds recycled phosphorus could fertilize 100 percent of U.S. corn
The world has a problem. A phosphorus problem. Needed to fertilize crops, the bulk of phosphorus comes from nonrenewable phosphate rock. While China mines the most — producing almost half the world’s phosphorus — Morocco alone controls three-fourths of global phosphate rock reserves. Year by year those global reserves dwindle, leaving phosphate rock that’s ever lower in ...

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 ...

Bacterial contamination in Fresh produce
Fresh fruit and vegetables are an important part of our diet. If produce is contaminated by poorly sourced water, however, the implications can be fatal. While many people associate foodborne illness with meat and dairy, it is important to recognize that fruits and vegetables can pose a significant threat to public health if hygienic water sourcing is not upheld. We take a closer look this week ...

The Triple Challenge: Genetic Selection For Feed Efficiency
Like many other traditional industries such as automotive and banking, the agriculture and food markets are constantly faced with fundamental market shifts. New technology, science, digital capabilities, infrastructure, and viral marketing are beginning to converge, changing the environment and rules that many industries operate in. At Vytelle, we believe farmers are faced with what we refer to ...

Unearthing a sustainable soil health strategy
Most farmers can agree that although there’s no silver bullet to a bumper crop, healthy soil plays a crucial role, from seeding to harvest and beyond. But how much is understood about what really happens beneath the surface of the field? “Well-functioning soil will retain, provide and recycle nutrients and water, and will support a diverse array of biota in the soil-plant ...

Magnesium Bioavailability Update
What have we learned about magnesium nutrition in animals during the past few years? Several research reports have been published which increase our understanding of Mg utilization. While an earlier generation of researchers concentrated more of their efforts on solving the grass tetany problem, recent research has emphasized the areas of absorption, bioavailability of Mg sources, the effects of ...
