The industrialization of U.S. beef, dairy, hog, and poultry sectors has received considerable attention. There have been regional shifts in the geographical location of livestock inventories and livestock farms. This paper examines the trends in geographical concentrations of livestock sectors...

The parameters of an output distance function are estimated utilising unbalanced panel data from 300 UK dairy farms. Potential nitrate contamination of groundwater is modelled within the production process as an undesirable output and shadow prices (which can be interpreted as marginal abatement...

Effects of adding sulphuric acid to slurry by flushing the waste pits were studied in a commercial finishing unit with four identical sections. Each section included 300 pigs on fully slatted floors. Waste pits in two control sections had a pull-plug system installed for removal of slurry. The...

It is argued that information on farmer knowledge about characteristics, adaptability and management needs of different species and breeds of domestic animals, and farmer preferences about these traits are useful inputs in designing breeding policy and conservation strategy. The argument is...

Poverty, low crop and animal productivity and large-scale resource degradation are major problems in the agriculture sector in the East African highlands. Among others, integration of forage legumes in cereal based cropping systems has been proposed as a promising strategy to improve the...

Cattle rearing in humid west Africa was nearly impossible in the past owing to the prevalence of trypanosomiasis, a disease caused by the tsetse fly. However, in recent times, with population pressure, jungle clearance, crop cultivation and tsetse control measures, the challenge has been...

The incorporation of livestock into alley farming systems, in which food or forage crops are grown between hedges of multipurpose trees that are regularly pruned for mulch and/or forage, has been studied for over 10 years in Africa. Prunings from leguminous trees such as Leucaena and Gliricidia...

The impact of climate change has become a major concern within the agricultural profession. While many studies on Climate Change Impact Assessment (CCIA) deal with crop farming, little has been done with regard to livestock farming. This paper aims to shed light on the present state of research...
