Linking coping styles and enzymatic activity of energy metabolism in the wedge sole (Dicologlossa cuneata)
Contributor(s):: De la Roca, Elena, Sánchez, Beatríz, López, Juan Manuel, Herves, María Antonia, Canalejo, Antonio, Herrera, Marcelino
Knowledge of individual behavioural variations (coping styles) can be a very useful tool for aquaculture, since it could allow to adapt the culture conditions to the different behavioural traits and, thus, to reduce the stress in the fish getting in this way a better production. The objective of...
Which measures of acceleration best estimate the duration of locomotor play by dairy calves?
Contributor(s):: Luu, John, Johnsen, Julie Føske, Passillé, Anne Marie de, Rushen, Jeffrey
Measures of acceleration have been used as automated measures of the locomotor play of calves. We examined which measures of acceleration were best correlated with locomotor play and how the sampling rate of the accelerometer affected the correlations. Accelerometers were attached to 30 6–7...
Activity patterns in reindeer with domestic vs. wild ancestry
Contributor(s):: Reimers, Eigil, Tsegaye, Diress, Colman, Jonathan E., Eftestøl, Sindre
We analyzed GPS-based activity patterns for two wild reindeer (Rangifer tarandus tarandus) herds: Norefjell-Reinsjøfjell with domestic ancestry and larger average body size and Rondane with wild ancestry and smaller body sizes. We compared activity patterns and tested whether these could...
Flavour preference acquired via a beverage-induced conditioning and its transposition to solid food: Sucrose but not maltodextrin or saccharin induced significant flavour preferences in pigs
Contributor(s):: Clouard, Caroline, Chataignier, Mathieu, Meunier-Salaün, Marie-Christine, Val-Laillet, David
When exposed to novel food during food transitions, growing pigs often elicit a neophobic response that is responsible for decreased food consumption. Flavour preference conditioning may represent an interesting way to reduce neophobia and improve food intake in growing pigs. The present series...
Evaluating measures of exploratory behaviour in sows around farrowing and during lactation—A pilot study
Contributor(s):: Valros, Anna, Pedersen, Lene Juul, Pöytäkangas, Merja, Jensen, Margit Bak
There are very few studies on the need to perform exploratory behaviour of sows around farrowing and during lactation, except for during the nest-building period. Exploratory behaviour in pigs may reflect appetitive foraging motivated by hunger, or appetitive behaviour related to other...
Assessing feeding motivation in sheep using different behavioural demand models and measures
Contributor(s):: Doughty, Amanda K., Ferguson, Drewe, Matthews, Lindsay R., Hinch, Geoff N.
Motivation tests have been used to assess the strength of an animals drive to obtain specific resources and, indirectly to gain insight into the animal’s welfare state as it is likely that chronic high motivation for unobtainable resources leads to diminished welfare. A variety of measures have...
A veterinary perspective on preventing injuries and other problems that shorten the life of working dogs

Characteristics of Excitable Dog Behavior Based on Owners' Report from a Self-Selected Study
Contributor(s):: Anastasia Shabelansky, Seana Dowling-Guyer
Past research has found that excitable dog behavior is prevalent among sheltered and owned dogs and many times is a reason for canine relinquishment. In spite of its prevalence in the canine population, excitable behavior is relatively unstudied in the scientific literature. The intent of this...

Recommended management strategies to limit anthropogenic noise impacts on greater sage-grouse in Wyoming

Stakeholder contemporary knowledge needs regarding the potential effects of tall structures on sage-grouse

Energy intake and expenditure of improvised explosive device detection dogs
Contributor(s):: Phillips, S. P., Kutzner-Mulligan, J., Davis, M.
Improvised explosive device detection (IDD) dogs explore up to 40 km of land daily and therefore have energetic demands that may be above the National Research Council's requirement for working dogs. This study was designed to quantify metabolic energy intake (MEI) and total energy expenditure...
Maintenance energy requirements of odor detection, explosive detection and human detection working dogs
Contributor(s):: Mullis, R. A., Witzel, A. L., Price, J.
Despite their important role in security, little is known about the energy requirements of working dogs such as odor, explosive and human detection dogs. Previous researchers have evaluated the energy requirements of individual canine breeds as well as dogs in exercise roles such as sprint...
A test of "nutritional wisdom" in perch ( Perca fluviatilis) by self-selection of encapsulated macronutrients
Contributor(s):: Brannas, E., Strand, A.
Developing optimal diets based on fish macronutrient requirements is an expensive and laborious task requiring years of research. However, many species of fish can compose a species-specific optimal diet from single source macronutrients in capsules through self-selection. Eurasian perch is a...
Understanding feeding patterns in growing pigs by modelling growth and motivation
Contributor(s):: Boumans, I. J. M. M., Bokkers, E. A. M., Hofstede, G. J., Boer, I. J. M. de
Feeding is an essential behaviour for body maintenance in pigs and closely related to their growth and productivity performance. Mechanisms underlying feeding behaviour in pigs are still unclear. Understanding these mechanisms can provide valuable insights into the complex interactions among...
Effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females
Contributor(s):: Emous, R. A. van, Kwakkel, R., Krimpen, M. van, Hendriks, W.
An experiment was conducted to determine the effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females. A 2*3*2 factorial arrangement of treatments was used. A total of 2880 Ross 308...
The rationality of biofuel certification: a critical examination of EU biofuel policy
Contributor(s):: Pols, A. J. K.
Certification for biofuels has been developed to ensure that biofuel production methods adhere to social and environmental sustainability standards. As such, requiring biofuel production to be certified has become part of EU policy through the 2009 renewable energy directive (RED), that aims to...

Nutritional ecology of obesity: from humans to companion animals
Contributor(s):: Raubenheimer, D., Machovsky-Capuska, G. E., Gosby, A. K., Simpson, S.
We apply nutritional geometry, a framework for modelling the interactive effects of nutrients on animals, to help understand the role of modern environments in the obesity pandemic. Evidence suggests that humans regulate the intake of protein energy (PE) more strongly than non-protein energy...
Pushed to the limit: food abundance determines tag-induced harm in penguins
Contributor(s):: Wilson, R. P., Sala, J. E., Gomez-Laich, A., Ciancio, J., Quintana, F.
The energetic costs of animal movement change with body condition, although the consequences of this for foraging efficiency are rarely considered. We deployed externally attached devices to Magellanic penguins ( Spheniscus magellanicus), known to increase the costs of swimming via increased drag...
