Effect of housing density on growth, agonistic behaviour, and activity in hatchling saltwater crocodiles (Crocodylus porosus)
Contributor(s):: Brien, Matthew L., Webb, Grahame J., McGuinness, Keith A., Christian, Keith A.
The purpose of this study was to examine the effect of density on growth rate, agonistic behaviour, activity and use of space by hatchling C. porosus in captivity. Hatchling C. porosus were raised in identical enclosures (1.5m2) at different densities (3.3, 6.7, 13.3 and 20.0hatchlings/m2; or...
The use of perches and platforms by broiler chickens
Contributor(s):: Norring, Marianna, Kaukonen, Eija, Valros, Anna
Perching is considered an integral part of chicken behaviour, and is suggested to alleviate leg problems and enhance mobility in broilers, as it stimulates diversification of locomotion. The use of perches is, however, low in broilers. There is a need for investigation of elevated structures that...
Is behavioural enrichment always a success? Comparing food presentation strategies in an insectivorous lizard (Plica plica)
Contributor(s):: Januszczak, Inez Sukuna, Bryant, Zoe, Tapley, Benjamin, Gill, Iri, Harding, Luke, Michaels, Christopher John
Staggering food availability through a delivery device is a common way of providing behavioural enrichment as it is usually thought to increase the amount of natural behaviour due to the unpredictability of the food source. Tree-runner lizards (Plica plica) are a Neotropical, scansorial,...
The effect of space on behaviour in large groups of domestic cats kept indoors
Contributor(s):: Loberg, Jenny M., Lundmark, Frida
The domestic cat (Felis silvestris catus) originates from the solitary living African wildcat (Felis silvestris lybica). However, through domestication, the domestic cat has become more social towards conspecifics and group housing of cats is common, for example in cat shelters in some countries....
Using a three-axis accelerometer to identify and classify sheep behaviour at pasture
Contributor(s):: Alvarenga, F. A. P., Borges, I., Palkovič, L., Rodina, J., Oddy, V. H., Dobos, R. C.
Identifying and classifying feeding behaviour in free-ranging ruminants will help improve efficiency of animal production. Another potential benefit would be in understanding the role behaviour has in determining heritability of methane measurement. The aim of this study was to determine the...
Automated behavioural response assessment to a feeding event in two heritage chicken breeds
Contributor(s):: Fraess, Garrett A., Bench, Clover J., Tierney, Keith B.
Video was recorded for three consecutive days for two pens each of two breeds of heritage chickens, Rhode Island Red (RIR) and Barred Plymouth Rock (BPR) (34 birds/pen), before and following a feeding event. The feeding event occurred when a technician entered the pen to refill the food trough at...
Validation of HOBO Pendant® data loggers for automated step detection in two age classes of male turkeys: growers and finishers
Contributor(s):: Dalton, Hillary A., Wood, Benjamin J., Dickey, James P., Torrey, Stephanie
Activity levels can be used as a predictor of health status, physical condition, feed efficiency, and coping style in animals. Small, portable data loggers have been validated as an inexpensive and effective alternative to video or live observation for automated activity detection in several...
Reactions of sheep towards three sets of emotional stimuli: (In)Consistency in respect to stimulus valence and sheep identity
Contributor(s):: Gygax, Lorenz, Vögeli, Sabine
There is an increasing interest in affective states in applied animal behaviour science, because these states are thought to reflect welfare from the perspective of the animals. Also, it can be expected that individuals differ in how they consistently react to emotional challenges. Recently, we...
Characterizing changes in activity and feeding behaviour of lactating dairy cows during behavioural and silent oestrus
Contributor(s):: Zebari, Hawar M., Rutter, S. Mark, Bleach, Emma C. L.
The normal time budgets of dairy cows are influenced by oestrus, with cows spending less time resting and eating but more time walking. Previous studies have shown that cows spend approximately 21% less time feeding where the day of oestrus is assumed to be the day of successful artificial...
Early indicators of tail biting outbreaks in pigs
Contributor(s):: Wedin, Maya, Baxter, Emma M., Jack, Mhairi, Futro, Agnieszka, D’Eath, Richard B.
Tail biting outbreaks in pig farming cause suffering through pain and stress, and producers lose revenue due to carcass condemnation. Reliable behavioural indications of when an outbreak is imminent would provide farmers with tools for mitigating the outbreak in advance. This study investigated...
Feather pecking genotype and phenotype affect behavioural responses of laying hens
Contributor(s):: van der Eijk, Jerine A. J., Lammers, Aart, Li, Peiyun, Kjaer, Joergen B., Rodenburg, T. Bas
Feather pecking (FP) is a major welfare and economic issue in the egg production industry. Behavioural characteristics, such as fearfulness, have been related to FP. However, it is unknown how divergent selection on FP affects fearfulness in comparison to no selection on FP. Therefore, we...
Dairy goats use outdoor runs of high quality more regardless of the quality of indoor housing
Contributor(s):: Stachowicz, Joanna, Gygax, Lorenz, Hillmann, Edna, Wechsler, Beat, Keil, Nina Maria
For dairy goats in loose housing, access to an outdoor run has potential welfare benefits as it provides additional space, enables spatial separation and may offer items representing behavioural enrichment for the goats (e.g. brush, climbing possibilities). However, these benefits will only apply...

Of feral cats and pet cats
Contributor(s):: Bruce A. Vojak
Early last summer an article in our local newspaper caught my eye. Some well-deserved visibility was given to my friend, Dick Warner (Professor Emeritus of Natural Resources and Environmental Sciences), for the findings arising from his study of ferali and pet cats. Dick and his colleagues...
Associations between milk intake and activity in the first days of a calf's life and later growth and health
Contributor(s):: de Passillé, Anne Marie, Rabeyrin, Marine, Rushen, Jeffrey
We examined whether calves' milk intake and activity in the days after birth predict later growth and the risk of illness. Female Holstein calves ( n=130) were housed in individual pens where they were allowed ad libitum milk from birth to 5 days of age. Daily milk intakes were recorded and...
Development of personality tests to use in the field, stable over time and across situations, and linked to horses' show jumping performance
Contributor(s):: Lansade, Léa, Philippon, Pascaline, Hervé, Lucile, Vidament, Marianne
This study aimed to identify tests that include all the criteria necessary to characterise reliably the personality of horses on a large scale: stability of measures across situations and over time, evaluation of independent dimensions, links with use and easy to organise for a large number of...
