Food motivation in horses appears stable across different test situations
Contributor(s):: Olczak, Katarzyna, Winther Christensen, Janne, Klocek, Czesław
Food motivation may influence an animal's performance in food-rewarded learning tasks. Nevertheless, food is often used as a positive reinforcer in learning tasks to investigate cognitive abilities of farm animals, and to test effects of various treatments, such as environmental enrichment, on...
Facing disasters together: how keeping animals safe benefits humans before, during and after natural disasters

Behavioural, endocrine and cardiac autonomic responses to a model of startle in horses
Contributor(s):: Villas-Boas, Julia Dias, Dias, Daniel Penteado Martins, Trigo, Pablo Ignacio, Almeida, Norma Aparecida dos Santos, Almeida, Fernando Queiroz de, Medeiros, Magda Alves de
Startle is a fast response elicited by sudden acoustic, tactile or visual stimuli in a variety of animal species and in humans. The magnitude of startle response can be modulated by external and internal variables and can be a useful tool to study the sensory-motor integration in animals....
A close keeper-nonhuman animal distance does not reduce undesirable behavior in contact yard goats and sheep
Contributor(s):: Anderson, U. S., Maple, T. L., Bloomsmith, M. A.
This study investigated the relation between zookeeper-nonhuman animal distance and the undesirable behaviour that goats and sheep exhibited toward visitors of Zoo Atlanta's (Georgia, USA) contact yard. It hypothesized that a close distance between keeper and animal would be associated with a...
Effect of enclosure quality on reactivity and welfare of captive Soemmerring's gazelle ( Gazella soemmerringii )
Contributor(s):: Mansour, A. A. H., Zakaria, A. H., Fraser, A. F.
The welfare of nonhuman animals in zoos is a great challenge to the zookeeper. Changes in the behavioral response of captive animals to their immediate environment can be used as a method for evaluating their welfare status. This study evaluates reactive responses of 3 groups of captive...
Animal welfare: should we change housing to better accommodate the animal or change the animal to accommodate the housing?
Contributor(s):: Cheng, Heng-Wei
Animal welfare (well-being) can be generally defined as 'a state of harmony between the animal and its environment, characterized by optimal physical, behavioural and psychological functioning and high quality of the animal's life'. Since its inception in the early nineteenth century, through...
A behaviour test on German Shepherd dogs: heritability of seven different traits
Contributor(s):: Ruefenacht, S., Gebhardt-Henrich, S., Miyake, T., Gaillard, C.
In this study, genetic and non-genetic effects on behavioural traits were estimated, based on records of the field behaviour test of the Swiss German Shepherd Dog breeding club. This standardized test has been applied since 1949 and comprised the following seven traits: self-confidence, nerve...
Behavioural responses of piglets to castration: the effect of piglet age
Contributor(s):: Taylor, A. A., Weary, D. M., Lessard, M., Braithwaite, L.
It has long been assumed that neonatal animals are less sensitive than older animals to pain, and this reasoning has been used to recommend that routine surgical procedures be performed at an early age. In this study we tested if vocal and other behavioural responses to castration increase with...
Equine utilization of secondary reinforcement during response extinction and acquisition
Contributor(s):: McCall, C. A., Burgin, S. E.
48 horses were used to examine equine utilization of a secondary (learned) reinforcement signal. Phases I and II of the study investigated whether the secondary reinforcer could prolong extinction of a learned task. Phase III utilized the secondary reinforcer to train the horse to perform a new...
How do miniature pigs discriminate between people? Discrimination between people wearing coveralls of the same colour
Contributor(s):: Koba, Y., Tanida, H.
Seven experiments were conducted on 4 miniature pigs to determine: (1) whether the pigs can discriminate between people wearing the same coloured clothing and (2) what cues they rely on if they could discriminate. For 2 weeks before the experiments began, the pigs were conditioned in a Y-maze to...
Neonatal foal handling
Contributor(s):: Simpson, B. S.
Recent interest has focused on the advantage of intensively handling young foals as a means of producing more tractable horses, accustomed to humans and receptive to training. To date, the effect of this intensive handling, dubbed imprint training in the popular literature, is not tested. The...
Repeatability and reliability of an approach test to determine calves' responsiveness to humans: "a brief report"
Contributor(s):: Lensink, B. J., Reenen, C. G. van, Engel, B., Rodenburg, T. B., Veissier, I.
A test aiming to measure calves' responses to humans ("approach test") was conducted in two steps: during the first step (approach phase) the calves' reaction to the appearance of an unknown person (withdrawal or not) was observed during milk provision, during the second step (touch phase) the...
A note on the relationship between the behavioural response of lactating sows to humans and the survival of their piglets
Contributor(s):: Hemsworth, P. H., Pedersen, V., Cox, M., Cronin, G. M., Coleman, G. J.
The objective of this study was to examine the relationships, based on unit averages, between the behavioural responses of lactating sows to humans and the performance of sows in 25 farrowing units at a large commercial farm. The behavioural responses of 25 sows in each farrowing unit were...
Domestication - from behaviour to genes and back again
Contributor(s):: Jensen, P.
During domestication, animals have adapted with respect to behaviour and an array of other traits. This tends to give rise to a specific domestication phenotype, involving similar changes in colour, size, physiology and behaviour among different species. Hence, domestication offers a model for...
