1. The aim in this study was to evaluate cleaning and disinfection programmes in battery cage and on-floor layer houses …
1. A survey of the concentration and emission rates of aerial ammonia, nitrous oxide, methane, carbon dioxide, dust and endotoxin …
1. Production of total heat, divided into sensible and latent heat, together with carbon dioxide and animal activity were determined …
Environmental effects of economic activities are ultimately driven by consumption, via impacts of the production, use, and waste management phases of products and services ultimately consumed. Integrated product policy (IPP) addressing the life-cycle impacts of products forms an innovative new generation of environmental policy. Yet this policy requires insight into the final consumption expenditures and …
1. In a pen study, NH3 flux estimates were performed when clean wheat straw or wood shavings were used as …
Differences in soil, climate and socioeconomic conditions cause animal production to vary widely between European regions, notably in animal density and percentage landless farming. They have in common that animal products result from the cycling and redistribution of nutrients through soil, air, plants, animals and manure, with energy from photosynthesis or from the input of …
1. Three separate experiments were conducted to determine if the addition of carbohydrate sources directly to freshly-produced laying hen manure …
Poultry production faces increasing environmental challenges, in the United States and globally. Although the environmental impact of poultry production has …
The Ecological Footprint measures the amount of biologically productive land and water area required to support the demands of a …
Food consumption may account for upwards of 15% of U.S. per capita greenhouse gas emissions. Online carbon calculators can help consumers prioritize among dietary behaviors to minimize personal “carbon footprints,” leveraging against emissions-intensive industry practices. We reviewed the fitness of selected carbon calculators for measuring and communicating indirect GHG emissions from food consumption. Calculators were …
Research shows that livestock account for a significant proportion of greenhouse gas (GHG) emissions and global consumption of livestock products is growing rapidly. This paper reviews the life cycle analysis (LCA) approach to quantifying these emissions and argues that, given the dynamic complexity of our food system, it offers a limited understanding of livestock’s GHG …
The environmental assessment of human activities is presently a hot topic. It is not only important from an ecological perspective, …
The reduction of emissions of air pollutants is subject of international conventions, which include reporting of emissions in accordance with …
Anthropogenic warming is caused mainly by emissions of greenhouse gases (GHGs), such as carbon dioxide, methane, and nitrous oxide, with …
Animal welfare is usually assessed by measuring animals’ responses to different environments or procedures. The alternative approach examines animal decision making, assuming that even domestic animals in artificial environments are able to integrate all relevant inputs and select in their own best interests. These two approaches to animal welfare assessment have been pursued largely in …
The objective of this paper was to describe a method that enables a comparison of egg production systems for their contribution to sustainable development of egg production, using data from the Netherlands for demonstration purposes. One conventional system, the battery cage system, and two animal-friendly systems, the deep-litter and the aviary systems, illustrate this method. …
The success of welfare legislation for nonhuman animals rests upon primary producer compliance that, in turn, is affected by public willingness to pay (WTP) for such initiatives. Although the topic of the welfare of animals on farms (and relevant legislation) is becoming increasingly important to the Australian public, there remain relatively few recent assessments of …
