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 ...

Performance of a dispersion model to estimate methane loss from cattle in pens
Received for publication December 29, 2008. Accurate measurements of enteric methane (CH4) emissions from cattle (Bos taurus) are necessary to improve emission coefficients used in national emissions inventories, and to evaluate mitigation strategies. Our study was conducted to evaluate a novel approach that allowed near continuous CH4 measurement from beef cattle confined in pens. The backward ...

Supplementation strategies effects on performance of beef heifers grazing stockpiled pastures
The increased cost of inputs has led livestock producers in the southeastern United States to use alternative management practices to supplement beef cattle (Bos spp.) on pastures. The objective of this study was to evaluate the performance of beef heifers grazing stockpiled limpograss [Hemarthria altissima (Poir.) Stapf & C.E. Hubb.] pastures supplemented with cottonseed meal (CSM, Gossypium ...

Building reservation economies: Cattle, American Indians and the American West
Removal to reservations involved American Indians in changing economies and federal 'civilisation' programs that were fueled by beef cattle, breeding cattle, working cattle (oxen) and dairy cattle. As 19th century reservations expanded, Native Americans negotiated the bovine economies as consumers, labourers, producers, retailers and marketers. Cattle, working oxen and dairy cows were intended to ...

All-Natural KMI Zeolite for Animal Feed, Dairy & Compost
Feed Additive Zeolite is used widely by livestock farmers as an animal feed additive for beef cattle, dairy Cows, Swine, poultry (broilers & egg production), and sheep. Since Zeolite is the World’s only naturally occurring, negatively charged, mineral a great number of benefits in the feed process can result from the basic chemistry of the zeolite as an animal feed additive. Many ...

Simulating gross primary productivity of humid-temperate pastures
Although most pasture growth models simulate many above- and belowground components of the plant community, calibration and validation are usually based only on periodic measurements of aboveground forage yield. This research used daily measurements of gross primary productivity (GPP) to validate the photosynthesis subroutine of the Integrated Farm System Model (IFSM). The model was calibrated ...

A review of bovine spongiform encephalopathy and its management in Canada and the USA
Geographic proximity and a long history of integration between US and Canadian cattle industries have resulted in similar management of BSE risk factors. Both countries have had a single imported case of BSE followed by multiple endemic cases of the bovine disease. Comparable risk management strategies have been put in place, such as a ban on the feeding of ruminant materials to other ruminants, ...

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 ...

Impacts of beef producer compensation programmes to remediate negative economic outcomes of bovine spongiform encephalopathy in Canada
Before the first domestic case of bovine spongiform encephalopathy (BSE) was identified in May 2003, Canada was the world's third largest exporter of cattle behind the USA and Australia. After the detection of BSE, over 30 countries imposed an immediate ban on imported Canadian beef and cattle products, including the USA. The interdependence of the Canadian beef industry with that of the US ...

Barley yield and nutrient uptake for soil amended with fresh and composted cattle manure
Limited research exists on the long-term effect of fresh (FM) versus composted manure (CM) from beef cattle on barley (Hordeum vulgare L.) yield and nutrient uptake. Barley was grown (1999–2007) as silage on an irrigated clay loam soil in southern Alberta where organic amendments and fertilizer were annually applied for 9 yr in the fall of 1998 to 2006. The treatments were three rates (13, 39, 77 ...

Ruminant Animal Feed Production Business Plan
In recent years, more and more farmers who feed cattle, cow, sheep and other animals choose to make their own animal feed by purchasing a small set of ruminant animal feed production plant. How much does it cost to set up an animal feed production plant? What’s the price of small feed processing unit? How to make the best ruminant animal feed production business plan?

Sunset Colony Study
“We have had the Silver Bullet AG300 unit now for ten months with great measurable results. This system is currently on our water line, treating the swine gestation, farrowing and nursery. The unit can treat 75,000 gallons of water per day and will be injected into our large water tank to treat our swine gestation, farrowing, nursery, finishers and dairy. What I like about the Silver Bullet ...

Risk assessment and risk management of bovine spongiform encephalopathy in Portugal
Portugal was one of the first countries outside of the UK to detect indigenous bovine spongiform encephalopathy (BSE) cases. However, initial low compliance with control measures contributed to the occurrence of increasing numbers of cases. This resulted in Portugal being the only other country to be designated at a higher risk level (GBR IV) by the European Commission (EC). By 2003, Portugal had ...

Continued risk management of the diminishing bovine spongiform encephalopathy outbreak in the UK
The UK was the first country to detect bovine spongiform encephalopathy (BSE) in 1986, and has reported the vast majority (over 97%) of the world's BSE cases. BSE resulted in large economic losses, disbanding of the lead government agency responsible for managing the outbreak and a loss of public trust in government. Despite a World Organization for Animal Health designation of 'controlled BSE ...

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 ...

Reducing the Effects of Methane from Cows in Cattle Farming with Methane Monitors
In 2018, there were an estimated 1.002 billion head of cattle worldwide, an increase of 6.5 million head over 2017.1 Global meat production has continued, and is seemingly continuing, to rise and although cattle now accounts for a relatively smaller percentage of overall meat consumption, there were still over 68 billion tonnes of cattle meat produced in 2014.2 Beef exported from the US alone in ...

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 ...

Canola Farms in the Snake River Area
This past Memorial Day weekend the promise of great trout fishing in the Snake River led us across Washington state into Idaho and entertained us all with beautiful sites along the way. As the buildings and cars faded from view, the land opened up. The air got a bit fresher. The atmosphere a little quieter and colors more pronounced. But nothing stood out more than the glowing, yellow canola ...
