Abstract:
... A comprehensive toxicokinetic analysis of citrinin (CIT) revealed interspecies differences for all toxicokinetic parameters and in absolute oral bioavailability. Oral bioavailability for CIT was complete for broilers (113–131%), while ranging from 37 to 44% in pigs. CIT was more rapidly absorbed in pigs (Tₘₐₓ = 0.92 h) compared to broiler chickens (Tₘₐₓ = 7.33 h). The elimination of CIT was slower ...

This paper examines the extent of cost inefficiency at 120 small-scale broiler farms in the Ashanti Region of Ghana by the use of stochastic frontier cost function, which incorporates cost inefficiency effects. Furthermore, farm-specific determinants that help explain why cost inefficiencies are different across broiler farms are identified. The findings confirm the presence of cost inefficiencies ...

Abstract:
... In the South Indian city of Madurai, young women indicate ambivalent feelings about emblems of food globalization like fried chicken restaurant KFC. Here, the criticism extends beyond the multi-national company into a dichotomy people maintain between industrially produced broiler chicken and the indigenous “country chicken” raised at smaller scales. In this article, I draw on Foucauldian concepts ...

There is currently a lack of research investigating the effectiveness of commercial broiler enrichments, and in particular the ability of these additions to create opportunities for positive welfare. One aim of this study was to investigate whether offering broiler chickens enrichments that have recently been found to be preferred leads to increased levels of activity. A second aim was to investig ...
