Use of outdoor ranges by laying hens in different sized flocks
- S. Gebhardt-Henrich, M. Toscano, E. Fröhlich
- Psychology
- 1 June 2014
In studies assessing outdoor range use of laying hens, the number of hens seen on outdoor ranges is inversely correlated to flock size. The aim of this study was to assess individual ranging behavior… Expand
Causes of keel bone damage and their solutions in laying hens
- A. Harlander-Matauschek, T. Rodenburg, V. Sandilands, B. Tobalske, M. Toscano
- Business
- 1 September 2015
Keel bone damage (KBD) is a critical issue facing the contemporary laying hen industry due to the likely pain leading to compromised welfare and reduced productivity. Recent reports suggest that KBD,… Expand
Continuous monitoring of pop hole usage by commercially housed free-range hens throughout the production cycle
- G. Richards, L. Wilkins, +4 authors S. Brown
- Medicine
- Veterinary Record
- 16 August 2011
Free-range laying hens are able to move between the indoor house and range through exits termed pop holes. The aim of this study was to examine the proportion of the flock that used the pop holes and… Expand
Genetic selection to increase bone strength affects prevalence of keel bone damage and egg parameters in commercially housed laying hens.
- A. Stratmann, E. Fröhlich, S. Gebhardt-Henrich, A. Harlander-Matauschek, H. Würbel, M. Toscano
- Biology, Medicine
- Poultry science
- 1 May 2016
The prevalence of keel bone damage as well as external egg parameters of 2 pure lines divergently selected for high (H) and low (L) bone strength were investigated in 2 aviary systems under… Expand
Modification of aviary design reduces incidence of falls, collisions and keel bone damage in laying hens
- A. Stratmann, E. Fröhlich, S. Gebhardt-Henrich, A. Harlander-Matauschek, H. Würbel, M. Toscano
- Biology
- 1 April 2015
Non-cage housing systems for laying hens such as aviaries provide greater freedom to perform species-specific behavior and thus are thought to improve welfare of the birds; however, aviaries are… Expand
Soft Perches in an Aviary System Reduce Incidence of Keel Bone Damage in Laying Hens
- A. Stratmann, E. Fröhlich, +4 authors S. Gebhardt-Henrich
- Biology, Medicine
- PloS one
- 26 March 2015
Keel bone fractures and deviations are one of the major welfare and health issues in commercial laying hens. In non-cage housing systems like aviaries, falls and collisions with perches and other… Expand
Pop hole use by hens with different keel fracture status monitored throughout the laying period
- G. Richards, L. Wilkins, +4 authors S. Brown
- Medicine
- Veterinary Record
- 23 March 2012
The aim of this work was to study the effect of keel fractures on the extent to which free-range hens access the range through pop holes. Over two consecutive laying periods (two production years) a… Expand
Environmental Conditions and Body Temperature of Circus Elephants Transported During Relatively High and Low Temperature Conditions
- M. Toscano, T. Friend, C. Nevill
- 2008
The purpose of this study was to characterize how circus elephants’ body temperatures respond to transport during relatively hot and cold conditions. The environment within the trailers and rail cars… Expand

Effect of prenatal stress on subsequent response to mixing stress and a lipopolysaccharide challenge in pigs.
- D. Lay, H. Kattesh, +5 authors M. Roberts
- Medicine
- Journal of animal science
- 1 June 2011
Sows subjected to prenatal stress have been found to produce offspring that have altered responses to stress. Our objective was to determine if exposing a sow to stress would alter the response of… Expand
Development of an Ex Vivo Protocol to Model Bone Fracture in Laying Hens Resulting from Collisions
- M. Toscano, L. Wilkins, Georgina Millburn, Katherine Thorpe, J. Tarlton
- Biology, Medicine
- PloS one
- 13 June 2013
Fractures of the keel bone, a bone extending ventrally from the sternum, are a serious health and welfare problem in free range laying hens. Recent findings suggest that a major cause of keel damage… Expand
