The objective of the study was to identify risk factors for reintroduction of Actinobacillus pleuopneumoniae and Mycoplasma hyopneumoniae (enzootic pneumonia) onto pig farms in areas in Switzerland that were involved in an eradication programme from 1996 to 1999 and to assess the role of dealers in relation to these reinfections. The study was based on the comparison of pig farms that were rein...

The availability of epidemiological data in the early stages of an outbreak of an infectious disease is vital for modelers to make accurate predictions regarding the likely spread of disease and preferred intervention strategies. However, in some countries, the necessary demographic data are only available at an aggregate scale. We investigated the ability of models of livestock infectious dise...

Classification and prediction in agricultural systems are quite useful for effective planning. In this paper, logistic regression modeling has been employed for classification purposes on data pertaining to the area of agricultural ergonomics. Presence or absence of discomfort for the farm labourers in operating farm machineries has been considered as the dependent variable and associated quant...

Reliable data on the demographics of animal populations are essential for effective planning and execution of disease control programmes. To document the spatial distribution of different swine populations in Minnesota, the authors evaluated four sources of data from separate entities that maintain data independently and for different purposes. Although the total numbers of swine sites (aggrega...

Worldwide growth of offshore renewable energy production will provide marine organisms with new hard substrate for colonization in terms of artificial reefs. The artificial reef effect is important when planning offshore installations since it can create habitat enhancement. Wind power is the most advanced technology within offshore renewable energy sources and there is an urgent need to study ...

Eff orts to exclude disease organisms from farms growing irrigated lettuce and leafy vegetables on California’s central coast are confl icting with traditionally accepted strategies to protect surface water quality. To begin resolving this dilemma, over 100 offi cials, researchers, and industry representatives gathered in April 2007 to set research priorities that could lead to eff ective co-ma...

The purpose of this paper was to identify effective dairy farm management adjustments related to recent structural changes in agricultural commodity markets because of expanded biofuels production and other market factors. We developed a mathematical programming model of a representative dairy farm in New York State to estimate the effects of changes in the relative prices of important feed com...

In 2012, the authors undertook a study of the challenges facing government and private veterinarians in responding to the human element of farm animal welfare incidents (i.e. the personal problems and difficulties of farmers that can result in farm animal neglect). This paper reports their findings and examines the role of veterinarians in responding to the difficulties of farmers. It also look...

Power quality issues associated with the fixed speed wind farm substation located at Coimbatore district are investigated as the wind generators are tripping frequently. The investigations are carried out using two power quality analyzers, Fluke 435 and Dranetz PX5.8, with one of them connected at group control breaker of the 110 kV feeder and the other at the selected 0.69 kV generator busbar ...
