Perch Positioning Affects both Laying Hen Locomotion and Forces Experienced at the Keel
The aim of this study was to assess the effect of perch positioning on laying hens’ locomotion and the resulting energy experienced at the keel. Twenty Nick Chick and 20 Brown Nick hens were trained to transition from a platform to a perch in several ...

Skeletal variation in bird domestication: limb proportions and sternum in chicken, with comparisons to mallard ducks and Muscovy ducks [PDF]
Background Domestication, including selective breeding, can lead to morphological changes of biomechanical relevance. In birds, limb proportions and sternum characteristics are of great importance and have been studied in the past for their relation with

Group level measures of welfare flocks have been criticized on the grounds that they give only average measures and overlook the welfare of individual animals. However, we here show that the group-level optical flow patterns made by broiler flocks can be

Detection of polymorphisms and protein domain architectures in rabbit toll-like receptor 2
Toll-like receptors (TLRs) recognise pathogen-associated molecular patterns (PAMPs) derived from pathogens and participate in activation of the immune responses. The TLR2 gene can recognise PAMPs specific to bacterial diseases such as pneumonia.

Neuroleptanalgesia in the rabbit [PDF]
The efficacy of the neuroleptanalgesic combinations of fentanyl-fluanisone with diazapam; and etorphine-methotrimeprazine, either alone, or with diazepam, was investigated in the rabbit. The effects of these drugs on some cardiovascular variables were studied in chronically catheterized rabbits.

Influence of weaning age (28 vs. 63 d) on quantitative and qualitative carcass traits of rabbits [PDF]
Nowadays there is an increasing interest towards breeding systems, also for rabbit meat production, that are more mindful of animal welfare through an attenuation of the productive cycles intensity.

Early Onset of Laying and Bumblefoot Favor Keel Bone Fractures
Numerous studies have demonstrated influences of hybrid, feed, and housing on prevalence of keel bone fractures, but influences of behavior and production on an individual level are less known.

Dietary niche partitioning between sympatric brown hares and rabbits [PDF]
Coexistence of ecologically similar species is sustained by niche partitioning, a fundamental element of which is diet. Overlapping of resource requirements between sympatric species can create interspecific competitive or facilitative effects on the ...
