The oxytocin system has a crucial role in human sociality; several results prove that polymorphisms of the oxytocin receptor gene are related to complex social behaviors in humans. Dogs' parallel evolution with humans and their adaptation to the human environment has made them a useful...
Structural variants in genes associated with human Williams-Beuren syndrome underlie stereotypical hypersociability in domestic dogs

Although considerable progress has been made in understanding the genetic basis of morphologic traits (for example, body size and coat color) in dogs and wolves, the genetic basis of their behavioral divergence is poorly understood. An integrative approach using both behavioral and genetic data...

A standardized ethogram for the Felidae: a tool for behavioral researchers
| Contributor(s):: Stanton, L. A., Sullivan, M. S., Fazio, J. M.
Standardized ethograms offer many practical benefits to behavioral researchers, and several examples exist today for various species and taxa. Despite historic evidence that suggests the family Felidae share similar behavioral repertoires, no standardized ethogram providing comprehensive...
The relationship between coat colour phenotype and equine behaviour: a pilot study
| Contributor(s):: Finn, J. L., Haase, B., Willet, C. E., Rooy, D. van, Chew, T., Wade, C. M., Hamilton, N. A., Velie, B. D.
Mutations in the genes influencing melanocytes not only affect the colour of an animal, but are also believed to impact physiological and behavioural functions. When this is taken into consideration, the common perception among horse owners that the chestnut coat colour is associated with adverse...
Dominance rank is associated with body condition in outdoor-living domestic horses ( Equus caballus)
| Contributor(s):: Giles, S. L., Nicol, C. J., Harris, P. A., Rands, S. A.
The aim of our study was to explore the association between dominance rank and body condition in outdoor group-living domestic horses, Equus caballus. Social interactions were recorded using a video camera during a feeding test, applied to 203 horses in 42 herds. Dominance rank was assigned to...
Canine olfactory receptor gene polymorphism and its relation to odor detection performance by sniffer dogs

Gut microbiota of humans, dogs and cats: current knowledge and future opportunities and challenges
| Contributor(s):: Deng, P., Swanson, K. S.
High-throughput DNA sequencing techniques allow for the identification and characterisation of microbes and their genes (microbiome). Using these new techniques, microbial populations in several niches of the human body, including the oral and nasal cavities, skin, urogenital tract and...
Differences in open field behavior between heterozygous and homozygous negative gilts for the RYR(1) gene
| Contributor(s):: Fabrega, E., Diestre, A., Font, J., Carrion, D., Velarde, A., Ruiz-de-la-Torre, J. L., Manteca, X.
A test widely used to assess fear and novelty responses in domestic species is the open field. The aim of this study was to investigate the effect of RYR(1) genotype on open field behavior in growing pigs. The study subjected 15 heterozygous (Nn) and 15 RYR(1)-free (NN) gilts of 19 weeks of age...
Behaviour epigenetics - the connection between environment, stress and welfare
| Contributor(s):: Jensen, P.
Epigenetics refers to chemical modifications of DNA, which do not change the base-pair sequence. This involves, for example, methylation of cytosine and different alterations in histone chemistry. Such modifications affect how genes are expressed and can occur as a response to stress, mediated by...
Purebred dogs and canine wellbeing
| Contributor(s):: Jeppsson, S.
Breeders of purebred dogs usually have several goals they want to accomplish, of which canine wellbeing is one. The purpose of this article is to investigate what we ought to do given this goal. Breeders typically think that they fulfil their wellbeing-related duties by doing the best they can...
Reliability and validity of a questionnaire survey in canine anxiety research
| Contributor(s):: Tiira, K., Lohi, H.
Canine behavior can be assessed through behavioral testing or questionnaire surveys. Behavioral tests, often observed by independent experts, can provide objective data, but capture only a short behavioral sequence in a defined situation and are practical only for small study cohorts....
The role of genes, epigenetics and ontogeny in behavioural development
| Contributor(s):: Rodenburg, T. B.
This review focuses on the role of genes, epigenetics and ontogeny in behavioural development of animals. The behavioural characteristics of an individual are determined by its genes and by its physical and social environment. Not only the individual's early life and current environment are of...
Antinociceptive effects of buprenorphine in zebrafish larvae: an alternative for rodent models to study pain and nociception?
| Contributor(s):: Steenbergen, P. J., Bardine, N.
The underlying processes of nociception and pain are, despite the rodent models available, still not fully understood. One of the drawbacks of rodent model systems is the difficulty to screen compound libraries for their influence on nociception, thus slowing down the discovery of novel...
Responses to novel situations of female and castrated male pigs with divergent social breeding values and different backtest classifications in barren and straw-enriched housing
| Contributor(s):: Reimert, I., Rodenburg, T. B., Ursinus, W. W., Kemp, B., Bolhuis, J. E.
The growth of a pig is not only affected by its own genes, but also by the genes of its pen mates. This indirect effect on a pig's growth is represented as social breeding value (SBV) in a newly developed breeding model. It has been hypothesized that pigs could affect their pen mates' growth...

A 71-year-old woman from Tennessee, USA with a 3-week history of a productive, nonbloody cough was evaluated. Chest radiograph showed infiltrates and atelectasis in the upper lobe of the right lung. A tuberculosis (TB) skin test resulted in a 14-mm area of induration. Sputum stained positive for...
