Endemic diseases of cattle, such as bovine viral diarrhea, have significant impact on production efficiency of food of animal origin with consequences for animal welfare and climate change reduction targets. Many modeling studies focus on the local scale, examining the on-farm dynamics of this infectious disease. However, insight into prevalence and control across a network of farms ultimately ...
REASONS FOR PERFORMING STUDY Equine herpesvirus 1 (EHV-1) is one of the most common causes of infectious abortion in mares. Analysing the demography of outbreaks and detailing subsequent reproductive performance of affected mares will assist in the management of future (threatened) epizootics. OBJECTIVES To examine the epidemiology and reproductive outcomes of 2 EHV-1 abortion epizootics with...
An empirical model, based on the Theory of Planned Behaviour, was developed to test the hypothesis that differences in farmers goals, objectives and attitudes are a determinant of strategic and entrepreneurial behaviour and will, therefore, result in differences in farm size. The theory states that a person s behaviour results from his/her goals and intentions, attitudes, perceived behavioural ...
roducers now have the tools (grain carts with load cells, yield monitors, GPS) to do on-farm field research. Additionally, growers are being made aware of more and more products/management options that they might use. One might read farm magazines, talk to neighbors, attend extension and industry presentations, but still wonder whether a particular recommendation would be of benefit. So the que...
Farmers are key players in actions to halt biodiversity loss from farmland. However, if farmers are to sustain biodiversity, they must first be adequately informed about biodiversity and understand its drivers. Measuring biodiversity at the farm scale is difficult because of the structural complexity of many farms, and because different aspects of diversity can be considered desirable, e.g. spe...
OBJECTIVES To describe pediatric farm injuries experienced by children who were not engaged in farm work, but were injured by a farm work hazard and to identify priorities for primary prevention. DESIGN Secondary analysis of data from a novel evaluation of an injury control resource using a retrospective case series. DATA SOURCES Fatal, hospitalized, and restricted activity farm injuries fr...
Offshore wind farms constitute a new and fast growing industry all over the world. This study investigates the long term impact on harbour porpoises, Phocoena phocoena, for more than 10 years (2001–12) from the first large scale offshore wind farm in the world, Nysted Offshore Wind Farm, in the Danish western Baltic Sea (72× 2.3 MW turbines). The wind farm was brought into full operation in Dec...
The effect of monetary policy on the farm sector remains controversial. Studies attempting to quantify the effects of monetary disturbances on real farm prices report conflicting results: some find that positive monetary shocks increase real farm prices in the short run, while others detect no such effect. We offer a resolution of these conflicting findings by re-estimating existing models on a...
Tear staining or chromodacryorrhea refers to a dark stain below the inner corner of the eye, caused by porphyrin-pigmented secretion from the Harderian gland. It has been shown to be a consistent indicator of stress in rats and to correlate with social stress and a barren environment in pigs. The current study was, to our knowledge, the first to test it on commercial pig farms as a potential we...
