targeted extension for heterogeneous farming systems is a challenge in developing countries. farm type identification and characterization based on estimates of income from different farm components allows simplifying diversity in farming systems. use of multivariate statistical techniques, such as principal component analysis (pca) and cluster analysis (ca), help in such farm typology delineat...

This study applied multi agent simulation to investigate the impact of farm credit (an agricultural land-use change adaptation strategy) on farm household livelihood. General household and land use data were obtained from 186 sampled household. Two household types were identified; the first household type was better-off in terms of land area cultivated and income generated from rain-fed rice. O...

This paper presents a synthesis of the main theoretical and empirical contributions that analyse production choices of farm households living and operating in developing countries. The review is particularly concerned with recent micro-economic contributions that highlight the trade-off farm households typically face, between full-income risk and expected return, while making production decisio...

A prospective cohort study was performed to evaluate the prevalences and loads of Salmonella and Campylobacter spp. in farm and processing plant samples collected from 55 commercial broiler chicken flocks. Environmental samples were collected from broiler houses within 48 h before slaughter, and carcass rinses were performed on birds from the same flocks at 4 different stages of processing. Sal...

The growing use of wind energy as major energy source, has led to the construction of large wind farms. The control of such wind farms is typically separated into control at wind turbine level and at wind farm level. The wind farm controller assures that the wind farm produces the demanded amount of power, by providing set-points for the turbines in the farm. The local turbine control assures t...

Two commercial Midwestern egg-type chicken flocks experienced significant increases in mortality rates in April 2013 with clinical signs appearing in 17-week-old pullets in Farm A and in 46-week-old hens in Farm B. Average weekly mortality was 0.44% over a 4-week period in Farm A and 0.17% over an 8-week period in Farm B. On Farm A, flocks in the affected house had a 45% decrease in daily egg p...

Much uncertainty remains about the origin and public health implications of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA). This study aimed to investigate the occurrence and prevalence of MRSA in general and LA-MRSA in particular in pigs and farm workers in five states. We collected nasal swabs from pigs and farm workers at 45 swine herds (21 antibiotic-free herds; ...

Purpose: studying inheritance of the type behavioral reaction in farm sables. Materials and methods. To determine nature behavior animals, animals to presentation an external stimulus (“test on a stick”) was evaluated. According results testing sables, one three categories attributed categories: calm (friendly, coming contact with person), avoiding (cowardly, not responding subject) aggressive ...
