Encoding of Arousal and Physical Characteristics in Audible and Ultrasonic Vocalizations of Mongolian Gerbil Pups Testing Common Rules for Mammals
| Contributor(s):: Silberstein, Yara, Felmy, Felix, Scheumann, Marina
In mammals, common rules for the encoding of arousal and physical characteristics of the sender are suggested based on a similar vocal production apparatus. In this study, we want to investigate to what extent vocalizations of developing Mongolian gerbil pups fulfill these rules. We recorded...

Jog with your dog: dog owner exercise routines predict dog exercise routines and perception of ideal body weight
| Contributor(s):: Banton, S., Massow, M. von, Pezzali, J. G., Verbrugghe, A., Shoveller, A. K.
Canine obesity is becoming an increasingly prevalent concern among companion animal veterinarians and professionals alike. A number of sociodemographic, dietary, and exercise related variables have been shown to be predictive of a dog's bodyweight, however, all previous surveys designed to...

When is a Wistar a Wistar? Behavioral profiling of outbred Wistar rats from five different suppliers using the MCSF test
| Contributor(s):: Palm, Sara, Hävermark, Åsa, Meyerson, Bengt J., Nylander, Ingrid, Roman, Erika
The same strain of rats purchased from different suppliers may exhibit behavioral differences that could give rise to variability and deficient repeatability. We have previously demonstrated that outbred Wistar rats from different suppliers display striking differences in voluntary alcohol...

The effect of maternal care and infrared beak trimming on development, performance and behavior of Silver Nick hens
| Contributor(s):: Angevaare, Milou J., Prins, Sander, van der Staay, Franz Josef, Nordquist, Rebecca E.
In the commercial poultry industry, feather pecking leads to damage to the chickens and an increased mortality rate. The effects of two (possible) feather pecking prevention methods, infrared trimming and maternal care, on production parameters, fear, sociality, learning, feeding behavior, and...

An automated positioning system for monitoring chickens' location: Effects of wearing a backpack on behaviour, leg health and production
| Contributor(s):: Stadig, Lisanne M., Rodenburg, T. Bas, Ampe, Bart, Reubens, Bert, Tuyttens, Frank A. M.
Automated tracking of the location of individual chickens is becoming more common in behavioural research. This technology has several advantages including gathering large amounts of data and monitoring of individual animals as opposed to flocks. To ensure the quality of the research the...

Sexual behaviour in sheep is driven by body condition and the related nutritional and metabolic status
| Contributor(s):: Alhamada, Moutaz, Debus, Nathalie, González-García, Eliel, Bocquier, François
To evaluate the effects of nutrition on the sexual behaviour of ewes, forty-eight mature (7.6±1.9years old) Merino d’Arles ewes with an average initial body condition score (BCS=2.26±0.23) and similar body weight (BW=46.6±3.8kg) were fed three contrasting diets for three months. The diets...

Changes in leg health, skin, and plumage condition in domestic male turkeys of varying body weights
| Contributor(s):: Dalton, Hillary A., Wood, Benjamin J., Widowski, Tina M., Guerin, Michele T., Torrey, Stephanie
Injurious pecking in turkeys is a serious welfare and economic concern in commercial production. Yet, very little is known about the development of this behaviour, and whether it relates to physical characteristics of the turkey. The objective of this study was to investigate the relationships...

Short- and Long-Term Effects of Unpredictable Repeated Negative Stimuli on Japanese Quail's Fear of Humans
| Contributor(s):: Agathe Laurence, Sophie Lumineau, Ludovic Calandreau, Cécile Arnould, Christine Leterrier, Alain Boissy, Cécilia Houdelier
Numerous aversive events occur in poultry production, and if repeated and unpredictable, can result in an impaired welfare. Some events such as handling can be perceived negatively and it is of interest to understand how humans' behaviour could affect poultry's behaviours and especially...

Evaluation of the Prevalence and Risk Factors for Undernutrition in Hospitalized Dogs
| Contributor(s):: Jenifer Molina, Marta Hervera, Edgar Garcia Manzanilla, Carlos Torrente, Cecilia Villaverde
Hospitalized dogs are predisposed to undernutrition, which can potentially affect outcome. This study evaluated the prevalence of undernutrition in hospitalized dogs (measured as loss of body condition score, BCS and body weight, BW) and studied the risk factors that affect nutritional status,...

The influence of human behaviors in the increased prevalence of overweight dogs
| Contributor(s):: Nora J. Nealon, Julie M. Fagan
An increasing number of dogs are falling into the overweight and obese categories, paralleling the rise in obesity over the past few decades in people. This suggests that dogs, which interact closely with people, have been influenced by our sedentary lifestyles, over-sized portions and diets high...

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...

Effects of carprofen, meloxicam and butorphanol on broiler chickens' performance in mobility tests
| Contributor(s):: Hothersall, B., Caplen, G., Parker, R., Nicol, C. J., Waterman-Pearson, A. E., Weeks, C. A., Murrell, J. C.
Lame broiler chickens perform poorly in standardised mobility tests and have nociceptive thresholds that differ from those of non-lame birds, even when confounding factors such as differences in bodyweight are accounted for. This study investigated whether these altered responses could be due...

Maximum permissible load for Yonaguni ponies (Japanese landrace horses) trotting over a short, straight course
| Contributor(s):: Matsuura, A., Mano, H., Irimajiri, M., Hodate, K.
This study aimed to determine the load-bearing capacity of trotting Yonaguni ponies using gait analysis. The Yonaguni pony is one of the Japanese landrace horses, and has normal gait characteristics when trotting. As a breed they are small in stature and hence susceptible to the effect of the...

The influence of gentle interactions on avoidance distance towards humans, weight gain and physiological parameters in group-housed dairy calves
| Contributor(s):: Lurzel, S., Munsch, C., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.
The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We examined the effects of 42 min of gentle interactions...

Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs
| Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.
Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the...

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...
