Water quality impacts of free ranging cattle in semi-arid environments

Creator:: Larsen, Royce E.
Abstract:: The purpose of this study was to evaluate the effects that free ranging cattle have on water quality in semi-arid environments. There were three specific objectives: 1) To determine the concentration and distribution of cattle feces in meadows, riparian zones, and the associated uplands. 2) To determine the fecal deposition...

The use of off-stream water developments and various water gap configurations to modify the watering behavior of grazing cattle

Creator:: Clawson, Jeffrey E.
Abstract:: Two case studies were designed to study the effects of using off-stream water developments and water gap configurations to modify watering behavior of cattle. There were two objectives: 1) to evaluate an off-stream water source to reduce water quality impacts of grazing cattle on a mountain riparian zone during summer...

Quantifying the impacts of riparian cattle grazing at Soap Creek Ranch near Corvallis, Oregon

Creator:: McArthur, Cynthia
Abstract:: A documented case history of riparian grazing at Oregon State University's Soap Creek Ranch was conducted from 1999 to 2001. Impacts of four different riparian grazing treatments were evaluated. Emphasis was placed on investigating the relationship between riparian cattle use and water quality. Through a series of carefully designed and...

The control and fate of enteric bacteria in the environment with particular emphasis on the factors influencing fecal indicator survival in waste storage facilities

Creator:: Crane, Stuart R.
Abstract:: The indiscriminate release of fecal bacteria to the environment can present a public health hazard when pathogenic species gain access to drinking and recreational water sources. The extent of bacterial contamination of surface and ground waters associated with animal production units and waste application areas seems largely dependent on the...

Feasibility study for a Tillamook County dairy waste treatment and methane generation facility

Creator:: Edgar, Thom G.
Abstract:: With the expansion of the Tillamook Creamery, in Tillamook Oregon, to double or more its cheese production, the demand for milk presents an economic opportunity for the member dairies of the Tillamook County Creamery Association. Before area dairies can expand their herd size to increase milk production for the creamery,...

Migration of E. coli and solutes to tile drains via preferential and matrix flow

Creator:: Moreno, Daniel
Abstract:: The extent of agricultural drainage has created concern for its potential undesirable effects on surface water quality. Land applications of liquid manure on tile drain fields have the potential to transport solutes and bacteria to the drains following precipitation or irrigation events and many times are directly sent to a...

An economic comparison of three cattle grazing management strategies intended to improve riparian habitat and water quality

Creator:: Sharp, Jeffrey L.
Abstract:: Grazing of riparian forage by livestock may alter stream channel morphology in ways that impact nearby aquatic habitat, bank stability, vegetative cover and water quality. A number of grazing management practices have been proposed as a means to reduce the amount of time cattle spend in the riparian zone. The...

The effects of timber harvest and herbivory on understory vegetation and composition of beef cattle diets on forested rangelands

Creator:: Walburger, Kenric J.
Abstract:: The objectives of the experiment were to: 1) determine the relationship between overstory canopy cover and ungulate herbivory on understory production composition and diversity and 2) determine the effects of timber harvest, ungulate herbivory and season of use on botanical composition and nutritional quality of beef cattle diets. Three randomly...
