Palatability assessment in horses in relation to lateralization and temperament
Contributor(s):: Vinassa, Marica, Cavallini, Damiano, Galaverna, Davide, Baragli, Paolo, Raspa, Federica, Nery, Joana, Valle, Emanuela
Compared with other domestic animals, little is known about dietary preferences and feed palatability in equids. Furthermore, it is known that equids exhibit marked lateralization, that is, a preference for one side over the other, and that each individual differs in temperament. However, a gap...
Development and consistency of fearfulness in horses from foal to adult
Contributor(s):: Christensen, Janne Winther, Beblein, Carina, Malmkvist, Jens
Understanding the development and consistency of behavioural responses across life stages is of both fundamental and applied interest. In horses, fearfulness is particularly important because fear reactions are a major cause of human-horse accidents, and because fear is a negative emotional state...
Chute scoring as a potential method for assessing individual differences in arousal among ewes
Contributor(s):: Schiller, Kaleiah, McVey, Catherine, Doyle, Shayna, Horback, Kristina
Chute scoring has been used among beef and dairy operations as a method to gauge the relative phenotypic characteristics of animals based on response to physical restraint. While elements of the cattle chute score, such as tail flicking, exit speed, and side kicking, have been validated as...

Puppy Temperament Assessments Predict Breed and American Kennel Club Group but Not Adult Temperament
Contributor(s):: Robinson, Lauren M., Thompson, Rebekah Skiver, Ha, James C.
Puppy assessments for companion dogs have shown mixed long-term reliability. Temperament is cited among the reasons for surrendering dogs to shelters. A puppy temperament test that reliably predicts adult behavior is one potential way to lower the number of dogs given to shelters. This study used...
Temperamental turkeys: Reliability of behavioural responses to four tests of fear
Contributor(s):: Erasmus, Marisa, Swanson, Janice
Open field (OF), tonic immobility (TI), voluntary approach (VA) and novel object (NO) tests are used to assess fear responses, activity levels and coping styles of poultry. Fear tests are also used as part of welfare assessment programmes. Little is known about fear responses of turkeys....
Personality in felids: A review
Contributor(s):: Gartner, Marieke Cassia, Weiss, Alexander
Although there has been an increase in felid personality research, much more work is needed, with only 20 published studies, 17 of which focused on the domestic cat. Most studies show important implications for this type of research, but there is no consensus on terminology, method, or...
Personality assessment in African elephants (Loxodonta africana): Comparing the temporal stability of ethological coding versus trait rating
Contributor(s):: Horback, Kristina M., Miller, Lance J., Kuczaj, Stan A.
The consistency of personality assessment was addressed in this study of 12 zoological African elephants living at the San Diego Zoo Safari Park in Escondido, CA, USA during the 2010 and 2011 summer seasons. Using 480h of observational behavior data, three personality traits were determined based...
A novel approach to systematically compare behavioural patterns between and within groups of horses
Contributor(s):: Ellis, Andrea D., Stephenson, Melissa, Preece, Michaela, Harris, Pat
This study piloted a multiple aspect approach to assess differences or changes in equine behaviour, using physiological (heart rates – HR, salivary cortisol – SC) and behavioural measures in various routine (feed-time, riding, turning out) and test situations (novel situation tests NS: 2×...
Icelandic horses with the Silver coat colour show altered behaviour in a fear reaction test
Contributor(s):: Brunberg, Emma, Gille, Sanna, Mikko, Sofia, Lindgren, Gabriella, Keeling, Linda J.
The colour of a horse's coat has long been discussed to reflect its temperament. One opinion is that Silver coloured horses are nervous, difficult to handle and react more strongly to different fear stimuli. The objective with the present study was to investigate if mutations associated with the...
Behavioural and physiological responses of heifer calves to acute stressors: Long-term consistency and relationship with adult reactivity to milking
Contributor(s):: Van Reenen, Cornelis G., Van der Werf, Jozef T. N., O’Connell, Niamh E., Heutinck, Leonie F. M., Spoolder, Hans A. M., Jones, R. Bryan, Koolhaas, Jaap M., Blokhuis, Harry J.
The present study investigated the long-term consistency of individual differences in dairy cattles’ responses in tests of behavioural and hypothalamo–pituitary–adrenocortical (HPA) axis reactivity, as well as the relationship between responsiveness in behavioural tests and the reaction to first...
Behavioral differences among breeds of domestic dogs (Canis lupus familiaris): Current status of the science
Contributor(s):: Mehrkam, Lindsay R., Wynne, Clive D. L.
In both popular media and scientific literature, it is commonly stated that breeds of dogs differ behaviorally in substantial, consistent and predictable ways. Since the mid-twentieth century, scientists have asked whether meaningful behavioral differences exist between breeds of dogs. Today,...
Age over experience: Consistency of aggression and mounting behaviour in male and female pigs
Contributor(s):: Clark, Corinna C. A., D’Eath, Richard B.
Excessive aggression between pigs at mixing is a welfare and production issue resulting in stress, injuries and economic losses. If it can be demonstrated that aggression is a consistent behaviour trait, it might provide a means to reduce these losses. To test for consistency of aggressiveness,...
Who's afraid of the big bad glove? Testing for fear and its correlates in mink
Contributor(s):: Meagher, Rebecca K., Duncan, Ian, Bechard, Allison, Mason, Georgia J.
Fear in farm animals is a welfare and economic concern. For Scandinavian mink, the “stick test” is common for assessing fearfulness: a spatula is inserted into the cage and minks’ immediate responses are noted. However, on Ontario farms, fearfulness in the stick test was very rare and aggressive...
