to determine water quality as affected by applications of dairy
waste slurries to tiled and untiled soils.
Dairy cow waste...
Environmental concerns about urban air quality, global climate change, energy
security and economic considerations motivate a growing interest in alternative fuels for
the transportation sector. Ethanol, a fermentation-derived fuel, can be produced by
bioconversion of renewable materials, such as wood, grass, and waste. Combustion of
ethanol fuel, in both neat...
Nine feeding trials and four laboratory scale experiments were conducted in this study. The study consisted of: (1) use of grass straw:corn juice (CJ) silages with fishmeal and/or alfalfa hay supplementation in beef heifers, sheep, pregnant dairy heifers, water buffaloes and Hereford cows; (2) use of cull onions:grass straw silages...
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...
