Congress of Genetics Applied to Livestock Production Single Step Methods with a View towards Poultry Breeding

Single Step methods combine pedigree relationships and marker genotypes in a single conceptual and streamlined framework based on extending animal model BLUP to include marker genotypes. The extension can be done because genotypes at markers follow covariances described by the pedigree. This results in a relationship matrix that combines pedigree and markers, called H. Fitting H in Henderson’s ...

Using EMS’s to Improve Compliance on Livestock and Poultry Operations

Across the United States and abroad, innovative producers, processors, trade organizations and others in the agricultural sector are exploring the promise of Environmental Management Systems (EMS) to improve their environmental and business performance.

Greenhouse Gas Emissions from Livestock and Poultry

In 2008 the Environmental Protection Agency (EPA) estimated that only 6.4% of U.S. greenhouse gas (GHG) emissions originated from agriculture. Of this amount, 53.5% comes from animal agriculture. Agricultural activities are the largest source of N2O emissions in the U.S. accounting for 69% of the total N2O emissions for 2009. In animal agriculture, the greatest contributor to methane emissions ...

Air Quality and Emissions from Livestock and Poultry Production/Waste Management Systems

The objective of this paper is to summarize the available literature on the concentrations and emissions of odor, ammonia, nitrous oxide, hydrogen sulfide, methane, non-methane volatile organic carbon, dust, and microbial and endotoxin aerosols from livestock and poultry buildings and manure management systems (storage and treatment units). Animal production operations are a source of numerous ...
