A simple and inexpensive sulfonamide-screening test was evaluated using turkeys. An agar-diffusion procedure was developed to estimate the levels of sulfonamides in the edible tissues of turkeys by determining the drug level in whole blood. The analysis was adapted for use on whole blood that was easily collected from live birds on the farm with minimal equipment and skill. This Whole Blood Sul...

The economic well-being of most U.S. farm households depends on income from both onfarm and off-farm activities. Consequently, for many farm households, economic decisions (including technology adoption and other production decisions) are likely to be shaped by the allocation of managerial time among such activities. While time allocation decisions are usually not measured directly, we observe ...

For more than a decade, various farm-specific models have been developed by collaborating and integrating sensing technologies as step toward successful data-farm documentation effective decision-making. However, the stored gathered data continues to rely on cloud infrastructure or centralized platform control, which is particularly vulnerable threats such tampering, distortion, confidentiality...

Abstract A simulation method (SM), linear programming (LPM), project evaluation methods (PEMs), and whole farm modeling (WFM) were applied to analyze the investment appeal of a biogas on Russian farm. The was evaluated for constant input parameters. efficiency procedure elaborated evaluate maximize efficiency. includes defining optimal state situations “with project” “without project.” main ele...

Both organic and conventional farming processes require energy input in the form of diesel fuel for farming equipment, animal feed, and fertilizer compounds. The most significant difference between the two methods is the use in conventional farming of mineral fertilizers and pesticides that are minimally employed in organic management. It is argued that organic farming is more environmentally f...

The development and diffusion of hybrid maize in Zambia since the 1970s is a major achievement in African agriculture, but other than profitability studies, analyses of how this process has affected the economic well-being of smallholder farmers have been few. We test the relationship of hybrid seed use with six indicators of economic well-being. After using the control function/instrumental va...

The badger (Taxidea taxus). because of its strong propensity for digging, is considered North America's fossorial carnivore, feeding mostly on ground squirrels, pocket gophers, and mice throughout much of the western and midwestern continent. Badger excavations, primarily in search of food, produce mounds and deep holes which can damage alfalfa and other crops and damage farm equipment and wate...

Soil compaction is recognized as a yield limiting factor in crop production. Compaction problems continue to exist for several reasons, including; 1) the large size (mass) of agricultural vehicles; 2) increased operations on wet soils because of larger farm acreage and multi-axle driven equipment; and, 3) the lack of controlled traffic patterns in fields. Where compaction is identified as a pro...

BACKGROUND Neospora caninum is a protozoan parasite from phylum apicomplexa and an important agent causing abortion in cattle which produce notable economic loss all around the world. METHODS Dot-Elisa was set up performing checker board procedure and then 178 sera of cattle examined with commercial indirect ELISA and direct agglutination test (DAT) were also evaluated by dot-ELISA afterwards...

We developed a multimedia satellite network system based on the Internet protocol (IP) and personal computers. It enables collaborative distance education between outdoor and indoor environments. Integration of IP technologies and satellite communications enhances the flexibility of the network system. The satellite communication system enables us to communicate to and from outdoor environments...
