Emissions From Concentrated Animal Feeding Operations During Wet and Dry Periods in the Southeastern United States
… western Kentucky, there are several concentrated animal feeding operations (CAFOs) that emit a variety of gases, including sulfur dioxide (SO<sub>2</sub>). The hypothesis was that the concentration and spread of SO<sub>2</sub> emissions from these sources would differ between wet and dry periods …

Concentrated Animal Feeding Operations: Hazards, Environmental and Health Risks as the Latent Products of Late Modernity
<p>CAFOs raise tens of thousands of animals in confined cages and feedlots, feed them high calorie diets, and ship them to slaughter in record time. These factory farms (as they are sometimes called) devastate neighboring environments with the releases of toxic methane gas and animal waste. …

Phosphorus Losses From Simulated Dairy Land Uses of Management Intensive Grazing and Concentrated Animal Feeding Operations
… friendly alternative to concentrated animal feeding operations (CAFOs). However, questions remain regarding the amount of phosphorus (P) loss from pasture-based dairies. Therefore, the goal of this study was to quantify P losses via runoff from grazing dairy systems and CAFO hay …

Some studies of the chemistry and technology of soupfin shark liver oil
… at which vitamin A is being used in America for animal feeding. During the war years it has been used extensively for food fortification in England and Europe, and this will probably be continued for several years. It is very difficult to estimate the annual world consumption of vitamin A, but we …

Wireless Dust Sensor Network for a Feedlot Dust Abatement Study
The mobilization of animals across Concentrated Animal Feeding Operations (CAFOs) generates large dust plumes causing visibility and human health issues. The ability to measure with many sampling points across a field and to have vertical measurements would aid in the characterization of dust …

Changes in Composition and Functional Properties of Dairy Products Made With Altered Milk Fat
… amount of oleic acid infusion have to consider animal feeding behavior, nutritional quality of milk fat, and functional properties of targeted dairy products. Products under freezing temperatures, like ice creams, may tolerate higher oleic acid infusion levels than whipping creams or butter oil. …

Planning Gone Hog Wild: Mega-Hog Farm in a Mountain West County
… undesirable industries is the hog concentrated animal feeding operation, or CAFO. While a number of studies have explored the socio-economic and environmental aspects of hog farms, few studies have focused on the planning process and evaluated its effectiveness in dealing with the threats and …

Quantifying Acacia defences : understanding the role of hooks, spines and architecture
… that was tested against the results of three feeding simulation tests as well as actual animal feeding rates obtained from trials using nyala held in bomas. The stripping, biting and branching indices were shown to provide a good measure of the different components of a structural defence, …

The effects and fate of selected veterinary antibiotics in two Missouri anaerobic swine lagoons
… anaerobic lagoons used at two different confined animal feeding operations (CAFOs) which housed swine. Inhibition studies revealed that antibiotics commonly used in agriculture did partially inhibit methanogenesis in the two anaerobic lagoons studied. Bacitracin A, and three tetracycline, …

Private land, public interest : small town meets big dairy
… to prohibit the construction of a Concentrated Animal Feeding Operation (CAFO) in their county. In particular, it is an attempt to understand and document the process by which a sparsely-populated rural community organizes itself in an attempt to disallow this type of facility from being sited …

Avaliação da qualidade do leite cru produzido no município de Areia- PB
… of Paraíba, at May to December 2016. The animals chosen for this study had different ages and stages of lactation and All mestizos. All were fed to pasture, and some properties were mechanically milking and hand milking. The physical-chemical analysis was performed using the Ekomilk …

Cultivating Agricultural Resistance: Alternative Farming as Slow Modernity
… industrial agriculture are CAFOs (Confined Animal Feeding Operations) and monoculture crop production. This thesis seeks to find examples of producers refusing these methods as well as what motivates those producers to refuse, and what that refuse could mean politically. The project is …

Cattle manure characteristics in relation to manure accumulation period and seasonal impacts in the intermountain west
… as feedstock for AD ranges from food waste to animal waste, including manure. There are limited application of AD technology to process beef cattle manure compared to other manure sources due to factors such as method of collection processes (i.e., scraped on dry lots) and inconsistent methane …

Evaluation of the Economic, Social, and Biological Feasibility of Bioconverting Food Wastes with the Black Soldier Fly (Hermetia illucens)
… systems. Current efforts are composting and animal feeding. However, these food waste disposal practices rely on slow thermodynamic processes of composting or finding farmers with domestic animals capable of consuming the food wastes. Bioconversion, a potential alternative, is a waste …

An Evaluation of Palm-Oil Milling Effluent Treatment by Fermentation to Produce Animal Feed Protein
… produces a high protein fungal biomass, as an animal feed, to offset treatment costs. The viability of the 'Malima' system was found to depend on the value of the fungal biomass as an animal feed. Therefore the evaluation of the fungal biomass as a protein ingredient centred on animal feeding …

Water and Nutrient Use Evaluation of South Dakota Vegetated Treatment Systems
… preventing release of water and nutrients from animal feeding operations.<br /> Vegetated treatment systems at South Dakota feedlots were studied and analyzed for 1 to 3 years from 2005 to 2007. The systems were monitored for precipitation, sediment basin discharge, crop water use, and system …

Investigation of the Flow and Fate of Nitrate in Epikarst at the Savoy Experimental Watershed, Northwest Arkansas
… flow, and excess inputs of nutrients from animal feeding operations. One zone that is present in many karst regions and could play an important role in nitrate attenuation due to properties such as increased residence time and matrix-water contact is the upper, weathered portion of karst, …

Evaluating the Fate of Manure Nitrogen in Confined Dairy Waste Operations: a Full-Scale Waste Analysis and Start-Up Protocol for an Anammox-Based Treatment Technology Applicable to Dairy Waste Management
… characteristics throughout the confined animal feeding operation was completed. The results suggest that ammonia concentrations in the anaerobic storage facility was high enough to justify use of treatment technologies that reduce ammonia loads in stored dairy waste. A lightly loaded …

ENGINEERING INFORMATICS AND SYSTEMS MODELING FOR OPTIMIZATION OF ANIMAL MANURE MANAGEMENT
There is no doubt that animal feeding operations (AFO) significantly improve meat production at a lower cost. However, accumulative manure produced in AFOs cannot be efficiently utilized in a sustainable and economical way. How to develop the animal manure management strategy is a challenge for …

New applications of STEPL watershed modeling of CAFO feedlot runoff and implications of surface water impacts
Concentrated Animal Feeding Operation (CAFO) cattle feedlot runoff is hydrologically modeled using the Spreadsheet Tool for Estimating Pollutants Load (STEPL). STEPL estimates the annual nutrient load of nitrogen and phosphorus, among other pollutants, by land use for a watershed. The Dry Creek …
