BACKGROUND Pathogens are growing threats to wildlife. The rapid growth of marine salmon farms over the past two decades has increased host abundance for pathogenic sea lice in coastal waters, and wild juvenile salmon swimming past farms are frequently infected with lice. Here we report the first investigation of the potential role of salmon farms in transmitting sea lice to juvenile sockeye sal...

BACKGROUND This study examines the prevalence of drug resistance in gastrointestinal nematodes to macrocyclic lactones (ML) and benzimidazoles (BZ) in Lithuanian sheep using sensitive and precise in vitro methods. The survey was conducted from August 2013 to November 2014. Thirty-three farms with sheep previously treated with BZ and ivermectin (IVM) were included in the study. On 12 farms where...

Standard measures of productivity display enormous dispersion across farms in Africa. Crop yields and input intensities appear to vary greatly, seemingly conflict with a model efficient allocation farms. In this paper, we present theoretical framework for distinguishing between measurement error, unobserved heterogeneity, potential misallocation. Using rich panel data from Tanzania Uganda, esti...

Bulk tank milk from 28 dairy farms was sampled every second month for 2 yr to assess the effects of grassland management, production system and season on milk fatty acid (FA) composition, concentrations of fat-soluble vitamins, Se, and milk sensory quality. Grassland management varied in terms of time since establishment. Short-term grassland management (SG) was defined as establishment or rese...

There have been major structural changes in the beekeeping industry over the past 25 yr. The U.S. Census of Agriculture surveys indicate that colony inventory declined > 20% between 1982 and 2002, whereas the number of U.S. farms with apiculture enterprises fell > 70%. This decline in farm numbers was not uniform across different sized farms based on colony inventory--nearly 30,000 of the farms...

The present paper attempts to investigate whether the Sub-Measure 6.1 “Start-Up Aid for Young Farmers” payments of 2014–2020 Rural Development Programme have a role play in explaining Greek farms’ export orientation and performance through statistical analysis farm-level data. results demonstrate considerable differences farm structures between beneficiaries non-beneficiaries provide support co...

In 2011, Dutch animal production sectors started recording veterinary antimicrobial consumption. These data are used by the Netherlands Veterinary Medicines Authority to create transparency in and define benchmark indicators for veterinary consumption of antimicrobials. This paper presents the results of sector wide consumption of antimicrobials, in the form of prescriptions or deliveries, for ...

Organic farming technology may be relatively unknown to farmers at the time when they switch from conventional into organic farming. Therefore, experience gained over time and learning by doing may be important determinants in the efficiency of organic farming. It may also take time to reach the optimal nutrient stock of soil and optimal nutrient supply for arable crops under organic farming. T...

UNLABELLED Quinolone-resistant Escherichia coli (QREC) is common in feces from young calves, but the prevalence and genetic diversity of QREC in groups of cattle of other ages and the farm environment are unknown. The aims of the study were to obtain knowledge about the occurrence of QREC on dairy farms, the genetic diversity of QREC within and between farms, and how these relate to the number ...

In the Alps, summer farms are temporary units where the livestock herds are moved during summer to graze on highland pastures. Th is study aimed to analyze the role of summer farms in the dairy farming systems of the Trento province, in the eastern Italian Alps. Data on the structures and management of the 395 active summer farms were collected from the veterinarian services of the province: 34...
