Recently developed innovations may improve the economic and environmental sustainability of pig production systems. Generic models are needed to assess the impact of innovations on farm performance. Here we developed a stochastic bio-economic farm mo

Growing environmental concern in society combined with policy stimuli has encouraged farmers to switch from conventional to organic production technologies. However, so far not many have made this switch. This raises the question, what could lie behi

A linear programming model of a dairy farm, in which grass production and grassland use was originally modelled using one growing period and one area of land, is extended. To include seasonal and spatial elements of variation not allowed for in the o

Agriculture, and, in particular, animal production, contributes substantially to Duct environmental problems, i.e. acidification and pollution of ground- and surface-water. This paper focuses on the possibilities of reducing nitrogen and phosphorus e

This study estimated the effect of genetic change of live weight (LW) and dry-matter intake capacity (DMIC) on labour income (economic values) in dairy cattle under different production circumstances. Dutch production circumstances in the years 1998

Biological dairy farming is often advocated as a solution for environmental problems caused by Dutch dairy farming. At the same time, biological farming can improve animal welfare and increase income due to a higher milk price. In this paper the cent

A linear programming model of a dairy farm was used to explore the future for different types of Dutch dairy farms under different scenarios. The scenarios are consistent sets of changing factors that are considered external at farm level. The factor
