SUMMARY The potential costs and/or benefits associated with two epidemiological methods were compared. Using the same epide-miologic dataset (74 Israeli dairy herds tested for bovine paratuberculosis of which 57 farms were regarded to be infected, and 619 non-tested herds), the efficacy associated with the identification of the target population where control or preventive measures could be app...

Data collected between 1993 and 1996 from two Scottish hill farms were used to assess the potential importance of predation by foxes as a cause of lamb mortality. Farm 1 was in Midlothian and farm 2 in West Perthshire. Overall lamb mortality rates from birth onwards were 10.2 per cent for farm 1 and 9.3 per cent for farm 2. Sixteen lambs were identified as killed by foxes on the two farms durin...

OBJECTIVE To assess socio-economic indicators, nutritional status and living conditions of farm workers and their families, with the purpose to develop research and intervention programmes aimed at enhancing nutritional status and quality of life. DESIGN AND SETTING Three farm schools in two districts of the North-West Province and farming communities were selected. Anthropometrical measureme...

STUDY OBJECTIVE s: To describe the farm work patterns and the relationship between hours spent working on specific farm tasks and task specific work related injuries among women and men. DESIGN A cross sectional survey of farm operators and their spouses in an eight county area of Colorado was conducted. Personal interviews were conducted between 1993 and 1997. Interviews took between 45 minu...

It is well-known that wind farm noise is dominated by low-frequency energy at large distances from the wind farm, where the high frequency noise has been more attenuated than low-frequency noise. It has also been found that wind farm noise is highly variable with time due to the influence of atmospheric factors such as atmospheric turbulence, wake turbulence from upstream turbines and wind shea...

Family farming, crop science and ‘globalisation’ together largely determine progress against poverty. Faster in 1960-90 than at any time in world history, such progress has slowed down. So have ‘land reform’ and science-based rises in small farmers’ staples food productivity, while aid to agriculture has fallen by over two-thirds and farm prices have been further forced down (and farm science d...

BACKGROUND The aim of this study was to estimate the seroprevalence of Coxiella burnetii in dairy goat farms in the Netherlands and to identify risk factors for farm and goat seropositivity before mandatory vaccination started. We approached 334 eligible farms with more than 100 goats for serum sampling and a farm questionnaire. Per farm, median 21 goats were sampled. A farm was considered posi...

BACKGROUND Biosecurity routines at herd level may reduce the probability of introduction of disease into the herd, but some measures may be regarded as expensive and cumbersome for the farmers. Custom-made measures based on individual farm characteristics may aid in improving the actual application of on-farm biosecurity. The aim of the study was to provide a tool for calculating the effects of...
