Pig farms in the Netherlands producing boars have different levels of boar taint prevalence, as assessed by sensory evaluation with the human nose at the slaughter line. With a questionnaire to 152 Dutch pig producers (response rate 59%), farm and management characteristics were identified that are potentially associated with farm-level boar taint prevalence. Lower farm-level boar taint prevale...

Q fever, caused by Coxiella burnetii, is a recognized occupational infection in persons who have regular contact with ruminants. We determined C. burnetii seroprevalence in residents living or working on dairy cattle farms with ≥50 adult cows and identified risk factors for seropositivity. Serum samples from farm residents, including employees, were tested for C. burnetii IgG and IgM; seropreva...

We determine how the U.S. ethanol tax credit and import tariff affect the corn-ethanol-gasoline markets and how farm subsidies interact with these policies. We show how the ethanol tax credit and import tariff each uniquely affect the ethanol and gasoline prices. The ethanol import tariff alone increases the terms of trade in ethanol imports and corn exports, but decreases the terms of trade in...

This study was designed to measure technical efficiency and identify its determinants in crop production in Lafia Local government Area of Nasarawa State of Nigeria using a stochastic frontier production model. Double stage random sampling technique was used to select 100 crop farmers from which input-output data were collected based on 2005 cropping season. The results revealed that sixty five...

Little information currently exists regarding the risk of low-back disorders among youth who perform physically demanding farm activities. Thus, afield study was conducted in which children and adolescents who engage in farm work were recruited, fitted with a lumbar motion monitoring system, and then observed performing their usual chores. The lumbar motion monitor was used to record the trunk ...

Work under this investigation included farm survey, extension, and research components using both the CLSU research station and demonstration farms. An experiment was conducted for the determination of optimal stocking sizes, considering the growth and survival performance of various sizes of fingerlings along with economic factors. Size #22 sex-reversed nursery phase fingerlings of Nile tilapi...

The aim of this modelling study was to investigate the effect of large herd size (and land areas) on walking distances and milking interval (MI), and their impact on milk yield and economic penalties when 50% of the total diets were provided from home grown feed either as pasture or grazeable complementary forage rotation (CFR) in an automatic milking system (AMS). Twelve scenarios consisting o...

BACKGROUND Pre-weaning diarrhea in mink, also known as "sticky kits", is a syndrome and outbreaks occur every year on commercial mink farms in all mink producing countries. Morbidity and mortality can be considerable on a farm with huge economic consequences for the farmer as well as compromised welfare for the mink kits. Although efforts have been taken to identify etiologic agents involved in...

The prevalence of allergy is markedly low in children growing up on farms. An increasing number of studies indicate that the timing of food introduction may affect allergy development. We aimed to investigate if protection against allergy in farm environments may be mediated through differences in food-introduction practices between farm and non-farm families, using an explorative approach.
