Androstenone induces horses to be more compliant with human-horse interactions
Contributor(s):: Choi, Yeonju, Yoon, MinJung
Olfactory signals play an essential role in communication in animals. Pheromones are volatile or nonvolatile chemicals that trigger social responses among animals. Therefore, pheromone treatment could, in theory, be used to modify horse behavior to improve human-horse relationships. Androstenone...

Effects of learning an increasing number of odors on olfactory learning, memory and generalization in detection dogs
Contributor(s):: Waggoner, Paul, Lazarowski, Lucia, Hutchings, Bethany, Angle, Craig, Porritt, Fay
Detection dogs continue to represent the most effective technology for the detection of explosives and other contraband. As the number of target odors and their variants that detection dogs are required to learn continues to increase, understanding the capacity for odor learning and the effects...

The Untrained Response of Pet Dogs to Human Epileptic Seizures
| Contributor(s):: Powell, N. A., Ruffell, A., Arnott, G.
Epilepsy is a debilitating and potentially life-threatening neurological condition which affects approximately 65 million people worldwide. There is currently no reliable and simple early warning seizure-onset device available, which means many people with unstable epilepsy live in fear of...

Natural reproductive performance is associated with captive management in adult male giant pandas
| Contributor(s):: Zhang, Ming-yue, Zhang, Xiao-hui, Zhang, Ping, Liu, Yu-liang, An, Jun-hui, Wang, Dong-hui, Cai, Zhi-gang, Hou, Rong
Through the implementation of giant panda ex situ conservation breeding programs, the giant panda has successfully been protected and has attained many conservation achievements. As of 2019, there were nearly 600 captive giant pandas worldwide, and the number of captive populations and the...

Maintaining long-term odor memory and detection performance in dogs
| Contributor(s):: Lazarowski, Lucia, Waggoner, Paul, Hutchings, Bethany, Angle, Craig, Porritt, Fay
Detection dogs represent an essential resource for security and defense sectors, yet logistical and security constraints limit the frequency in which relevant maintenance training can occur. Further, the extents and limits of canine odor memory are unknown. The aims of this study were to...

Olfactory-based interspecific recognition of human emotions: Horses (Equus ferus caballus) can recognize fear and happiness body odour from humans (Homo sapiens)
| Contributor(s):: Sabiniewicz, Agnieszka, Tarnowska, Karolina, Świątek, Robert, Sorokowski, Piotr, Laska, Matthias
Emotional recognition has been demonstrated to occur between members of different species. However, the majority of studies on interspecific communication of emotions so far focused on the senses of vision and hearing while the contribution of the sense of smell has rarely been studied in this...

Using dogs to detect hidden corrosion
| Contributor(s):: Schoon, Adee, Fjellanger, Rune, Kjeldsen, Morten, Goss, Kai-Uwe
Dogs used as detectors in remote scent tracing (RST) technology usually detect the presence of explosives or contraband in scent samples collected by sucking air from containers or air freight. In this study, five dogs were trained to detect corrosion under the insulation (CUI) of pipes in scent...

Explosives detection by military working dogs: Olfactory generalization from components to mixtures
| Contributor(s):: Lazarowski, Lucia, Dorman, David C.
The training of scent detection dogs using samples of explosives or their chemical precursors is a well-established and documented practice. However an area of canine odor detection that remains under-studied regards a trained dog's perception of an explosive odor when more than one odorant is...

Differential responses of captive southern hairy-nosed wombats (Lasiorhinus latifrons) to the presence of faeces from different species and male and female conspecifics
| Contributor(s):: Descovich, Kristin A., Lisle, Allan T., Johnston, Stephen, Nicolson, Vere, Phillips, Clive J. C.
The southern hairy-nosed wombat (Lasiorhinus latifrons) appears to use scent marking, including defaecation, for social communication in the wild. This premise assumes that the receiver wombat is able to distinguish between faeces from different sources. To examine this theory, four types of...

Perception and emotions: On the relationships between stress and olfaction
| Contributor(s):: Bombail, Vincent
Adaptations to the ever changing social and physical environment are necessary, sometimes involving the stress response. Olfaction is a chemical sense allowing the detection of molecules in the air, and many species rely on it for social recognition and fundamental functions such as feeding or...

Development of test for determining olfactory investigation of complex odours in cattle
| Contributor(s):: Rørvang, Maria Vilain, Jensen, Margit Bak, Nielsen, Birte Lindstrøm
The sense of smell is likely to influence the behaviour of domestic and captive animals in a wide range of management and housing situations. In domestic cattle, there may be unexploited potential for using odours and olfaction in the management; however, published studies on bovine olfactory...

The influence of odour, taste and nutrients on feeding behaviour and food preferences in horses
| Contributor(s):: van den Berg, M., Giagos, V., Lee, C., Brown, W. Y., Cawdell-Smith, A. J., Hinch, G. N.
While it has been established that nutrients and flavours (odour, taste) play an important role in diet selection by horses, previous studies have not always clarified what type of flavouring (e.g. non-nutritive or nutritive) was used. Therefore, the objective of this study was to determine the...

Acceptance of novel food by horses: The influence of food cues and nutrient composition
| Contributor(s):: van den Berg, M., Giagos, V., Lee, C., Brown, W. Y., Hinch, G. N.
Compared to ruminants little is known about how horses modulate food intake and learn about flavour-to-post-ingestive consequences. While it has been suggested that due to hindgut fermentation horse⿿s foraging preferences may be largely influenced by sensory input (e.g. volatiles), it has been...

Performance of domestic dogs on an olfactory discrimination of a homologous series of alcohols
| Contributor(s):: Hall, Nathaniel J., Collada, Adriana, Smith, David W., Wynne, Clive D. L.
Dogs are deployed for the detection of a wide variety of chemical stimuli. Despite their wide use, little basic research has explored canine olfactory generalization and discrimination. In the present study, we assessed canine odor discrimination amongst a series of chemically-related aliphatic...

African elephants (Loxodonta africana) display remarkable olfactory acuity in human scent matching to sample performance
| Contributor(s):: von Dürckheim, Katharina E. M., Hoffman, Louwrens C., Leslie, Alison, Hensman, Michael C., Hensman, Sean, Schultz, Kip, Lee, Stephen
This paper presents data on the success rate of African elephants in human scent matching to sample performance. Working with equipment and protocols similar to those used in the training of forensic canine units in Europe, scent samples were collected on cotton squares from twenty-six humans of...
