Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour
Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.
Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...

Fear and stress measurements in pure and hybrid red-legged partridges
Contributor(s):: Campo, J. L., Garcia Davila, S., Garcia Gil, M., Torres, O., Santiago Moreno, J.
The purposes of this study were to examine the duration of induced tonic immobility (a reliable fear indicator considered a passive anti-predator behavioural trait) and two stress indicators (heterophil to lymphocyte ratio, and fluctuating asymmetry of leg length, middle-toe length, and wing...
Environmental complexity and use of space in slow growing free range chickens
Contributor(s):: Rodriguez-Aurrekoetxea, A., Leone, E. H., Estevez, I.
Production environments for meat poultry are generally bi-dimensional open areas where birds tend to cluster along the walls. We investigated the impact of increasing environmental complexity (EC) on slow-growing free-range chickens raised under commercial conditions. The study was conducted in...
Comparison of the tonic immobility duration, heterophil to lymphocyte ratio, and fluctuating asymmetry of chicks reared with or without a broody hen, and of broody and non-broody hens
Contributor(s):: Campo, J. L., Davila, S. G., Gil, M. G.
The purposes of this study were to determine whether rearing with a broody hen influenced duration of tonic immobility, heterophil to lymphocyte ratio, and relative fluctuating asymmetry of chicks and to analyze the differences between broody and non-broody hens in fear and stress indicators. A...
Natural incubation patterns and the effects of exposing eggs to light at various times during incubation on post-hatch fear and stress responses in broiler (meat) chickens
Contributor(s):: Archer, G. S., Mench, J. A.
Although environmental conditions during incubation can affect poultry welfare, one factor often overlooked in the commercial incubation of eggs is light. Light stimulation during embryonic development is now known to affect the physiology and behavior of broiler (meat) chickens post-hatch, but...
The effect of physiotherapy intervention to the pelvic region of experienced riders on seated postural stability and the symmetry of pressure distribution to the saddle: a preliminary study
Contributor(s):: Nevison, C. M., Timmis, M. A.
It is commonplace for trainers and judges to comment that riders are "crooked" or "collapsed in the hip." This asymmetrical posture will likely have a significant effect on stability/balance and may subsequently have a detrimental effect on performance. Although the effects of asymmetry on...

Group housing of adult silver fox ( Vulpes vulpes ) vixens in autumn: agonistic behaviour during the first days subsequent to mixing
Contributor(s):: Hovland, A. L., Akre, A. K., Bakken, M.
Due to farmed foxes' (Vulpes vulpes) social flexibility and possible motivation for intraspecific contact, group housing may act as an alternative housing procedure. Because initial social contact between silver foxes usually involves agonistic displays as a part of foxes' social dominance...
Association between vent pecking and fluctuating asymmetry, heterophil to lymphocyte ratio, and tonic immobility duration in chickens
Contributor(s):: Campo, J. L., Prieto, M. T., Garcia Davila, S.
The purpose of the present study was to analyse the relationship between incidence of vent pecking, fluctuating asymmetry, heterophil to lymphocyte ratio, and tonic immobility duration in fowls. The experiment (140 birds in three different replicates) measured the fluctuating asymmetry of several...
Influence of size and asymmetry of sexual characters in the rooster and hen on the number of eggs laid
Contributor(s):: Forkman, B., Corr, S.
The effects of asymmetry and size of secondary sexual characters of 127 hens and 32 cocks on egg laying was studied in a relaxed selection line of Brown Leghorn fowls that had a relatively low level of egg production (approximately 0.6-0.8 eggs/day). Each hen spent 24 h/week with the cocks; there...
Cow gait scores and kinematic gait data: can people see gait irregularities?
Contributor(s):: Nuffel, A. van, Sprenger, M., Tuyttens, F. A. M., Maertens, W.
Increasing lameness problems associated with intensified dairy cattle production has lead to the development of several techniques to automatically detect these problems. Comparisons of these new measuring techniques of cow locomotion with the conventional subjective observer scoring are scarce....
