Parent perceptions of the quality of life of pet dogs living with neuro-typically developing and neuro-atypically developing children: An exploratory study
out of 5 stars
| Contributor(s):: Sophie S. Hall, Hannah F. Wright, Daniel S. Mills
There is growing scientific and societal recognition of the role that pet dogs can play in healthy development of children; both those who are neuro-typically developing and those who live with a neuro-developmental disorder, such as autism or attention deficit hyperactivity disorder. However,...
Potential welfare impacts of kill-trapping European moles ( Talpa europaea) using scissor traps and duffus traps: a post mortem examination study
| Contributor(s):: Baker, S. E., Shaw, R. F., Atkinson, R. P. D., West, P., Macdonald, D. W.
Moles are widely trapped as pests on farms and amenity land in Britain. Spring traps for killing mammals generally require welfare approval in the UK, but mole traps are exempt. Previous research demonstrated wide variation in the mechanical performance of mole traps. In this context, we aimed to...
Domestication effects on behavioural traits and learning performance: comparing wild cavies to guinea pigs
| Contributor(s):: Brust, V., Guenther, A.
The domestication process leads to a change in behavioural traits, usually towards individuals that are less attentive to changes in their environment and less aggressive. Empirical evidence for a difference in cognitive performance, however, is scarce. Recently, a functional linkage between an...
Facilitating 'learning from mom how to eat like a pig' to improve welfare of piglets around weaning
| Contributor(s):: Oostindjer, M., Kemp, B., Brand, H. van den, Bolhuis, J. E.
Piglets in commercial husbandry are weaned abruptly and at a rather young age. Many weanling piglets are poorly adapted to ingest solid food, often resulting in a period of underfeeding. The underfeeding generally leads to a poor growth, diarrhoea occurrence and the development of damaging...
Puppy power! Using social cognition research tasks to improve socialization practices for domestic dogs ( Canis familiaris)
| Contributor(s):: Howell, T. J., Bennett, P. C.
Understanding the psychology of the domestic dog is a key element in both research and clinical applications for veterinary behaviorists. This article summarizes social cognitive skills observed in dogs in recent cognition studies. The tasks are grouped into the following 2 categories: those...

Developmental instability and light regime in chickens ( Gallus gallus )
| Contributor(s):: Moller, A. P., Sanotra, G. S., Vestergaard, K. S.
Fluctuating asymmetry, a measure of developmental instability, was measured in 3 skeletal characters in chickens raised under 3 different lighting regimes: (A) a 16:8 light-dark cycle, (B) a changing light regime, and (C) permanent light. Chickens reared under permanent light developed 40% larger...
Dustbathing and feather pecking in domestic chickens reared with and without access to sand
| Contributor(s):: Norgaard-Nielsen, G.
Eight groups of 10 female white Leghorn chicks were kept in wire floor cages from 1 day old. From 2 days of age four of the groups had continuous access to a wooden tray with dark dry sand, while the other groups had a wooden frame of the same size but without sand. Low intensity light (10 lux)...
Effects of feed- and water-based enrichment on activity and cannibalism in Muscovy ducklings
| Contributor(s):: Riber, A. B., Mench, J. A.
Cannibalism is a major problem for commercial production of Muscovy ducks (Cairina moschata). Surprisingly little is known about the ontogeny of cannibalism in ducks or how to reduce/prevent the problem in a welfare-friendly way. The preventative method typically used by the industry is...
Effects of prior video stimulation on open-field behaviour in domestic chicks
| Contributor(s):: Clarke, C. H., Jones, R. B.
Two experiments examined the effects of regular video stimulation on open-field behaviour in domestic chicks tested in the presence (Experiment 1) or absence (Experiment 2) of the familiar video image. In Experiment 1, socially housed chicks were either exposed daily from 2 to 8 days of age to...
The development of playful behaviour in piglets from birth to weaning in three farrowing environments
| Contributor(s):: Blackshaw, J. K., Swain, A. J., Blackshaw, A. W., Thomas, F. J. M., Gillies, K. J.
Observations of piglet play behaviour were recorded on real time video over 28 days during 6 periods for 6 h per period per litter (days 1-5, 6-10, 11-15, 16-20, 21-25, 26-30), from birth, in 3 farrowing environments: (i) an adjustable parallel crate (800 mm width) in a 2130 mm x 2105 mm pen;...

Stereotypies and compulsive behaviours - causes and possibilities of prevention
| Contributor(s):: Kuhne, F.
Despite the fact that livestock animals like companion pets have adapted through domestication to a life with human beings, they have the same demands on their environment as their feral conspecifics. Therefore, animal husbandry means keeping animals under conditions which are appropriate to the...

Factors which influence parturition in the mare and development of the foal
| Contributor(s):: Campitelli, S., Carenzi, C., Verga, M.
127 foals born to 127 mares were studied. Mares aged 5, 6-11 and 12 yr gave birth to foals with birth weights of 42.65+or-6.175, 51.07+or-7.031 and 46.05+or-8.816 kg resp. and foetal membrane weights of 5.45+or-1.000, 6.27+or-1.191 and 6.37+or-1.104 kg; differences between age groups were...
Behaviour test for eight-week old puppies - heritabilities of tested behaviour traits and its correspondence to later behaviour
| Contributor(s):: Wilsson, E., Sundgren, P. E.
Play and exploratory behaviour, and behaviour when isolated (total of 10 tests) was tested in 630 German Shepherd puppies at 8 weeks of age. All dogs were also tested at 450-600 days of age using to regimen for selection of service dogs. Significant sex differences were found in 4 of the 10 puppy...

Effect of feed and environmental enrichment on development of stereotypic wire-gnawing in laboratory mice
| Contributor(s):: Wurbel, H., Chapman, R., Rutland, C.
At 21 days of age, 16 pairs of male ICR laboratory mice were weaned and allocated to 4 treatment groups in a 2 x 2 factorial design matched for genetic background (litter) and body weight. Factor one was the hardness of feed pellets with a significant 2.5-fold difference between soft and hard...

Exposure to video images between 3 and 5 weeks of age decreases neophobia in domestic dogs
| Contributor(s):: Pluijmakers, J. J. T. M., Appleby, D. L., Bradshaw, J. W. S.
Restricted experience in early life is known to contribute to long-lasting predispositions to fear and anxiety in mammals. It is commonplace for young domestic dogs not to experience many features of the environment in which they will spend their adult lives until after 8 weeks of age:...
