“…Olfactory signals derived from the mammary or facial areas are commercially used to reduce stress responses in several species [28][29][30][31]; this further supports our notion that olfactory signals can suppress stress responses in animals. These signals fulfill the first criteria of being classified as pheromones; however, whether these olfactory signals fit the second criteria for pheromones has not been investigated yet.…”

Olfactory signals mediate social buffering of conditioned fear responses in male rats

In social animals, the presence of an affiliative conspecific alleviates acute stress responses, and this is called social buffering. We previously reported that social buffering mitigates the fear responses of male rats to auditory conditioned stimuli that had been paired with foot shocks. Subsequent studies revealed that signals that are perceived by the main olfactory epithelium are important for social buffering. Because olfactory signals are the signal perceived by the main olfactory epithelium, we hypothesized that we could induce the social buffering of conditioned fear responses by presenting olfactory signals that were derived from a conspecific. In order to test this hypothesis, we exposed fear-conditioned subjects to a conditioned stimulus either in a clean test box or in a test box that was odorized by keeping a conspecific in it as an odor donor beforehand. When the subjects were tested in the clean test box, they showed behavioral fear responses and enhanced Fos expression in the paraventricular nucleus. In contrast, the presence of conspecific olfactory signals blocked these fear responses and Fos expression. These results suggested that olfactory signals suppress conditioned fear responses. Fos expression in the posteromedial region of the olfactory peduncle and amygdala suggested that this suppression involves the same neural mechanisms as those of social buffering. Taken together, we concluded that olfactory signals mediate the social buffering of conditioned fear responses.

“…Recently a tendency to use synthetic pheromones to influence animal behavior can be observed and progress in that field can be noted (Gunn-Moore and Cameron 2004, Tod et al 2005, Falewee et al 2006, Frank et al 2010, Landsberg et al 2015. In domestic animals, except for appeasing pheromones which are commercially available for many species, among others research was also focused on sex pheromones (Izard and Vandenbergh 1982, Stevens et al 1982, Nishimura et al 1991, Rekwot et al 2001, Sankar and Archunan 2008.…”

The aim of this study was to evaluate the suitability of synthetic bitch sex pheromones (Eau' De Estrus ® , Synbiotics USA) for the stimulation of the reproductive reflexes in adult male dogs. In experiment I: anoestral bitches were applied synthetic (n=6) or natural (n=6) pheromones and their attractiveness was compared to the attractiveness of bitches in natural oestrus, In experiment II: swabs socked in natural estrual discharge or Eau D'Estrus were presented to male dogs and behavioral arousal (Exp. II a) and changes in blood flow in the penile artery reflecting erection (Exp. II b) were recorded. In experiment III the time dedicated for sniffing in experimental dogs was analyzed in relation to the type of attractant presented (natural estrual discharge or Eau D'Estrus). In all three experiments we observed the signs of sexual arousal, increased blood flow in the penile artery and increased time of sniffing only with natural pheromones. No signs of excitation or changes in penis perfusion were noted after the use of artificial pheromones. Our results did not support the suitability of Eau D'Estrus for male dog sexual stimulation.

“…Since this pheromone was discovered, several studies have confirmed its value in controlling stress in horses of all ages. research have showed that the appeasing pheromone in equines have role in controlled fearful situation (Falewee et al, 2006). And also in controlling stress of transportation during travel (Cozzi et al,.…”

Pheromones are found throughout the living world and are a primal form of communication. These chemical messengers are transported outside the body and have a direct developmental effect on hormone levels and/or behaviour. The pheromones play an important role in animal behavior and reproductive processes. This review article aims to highlight the role of pheromones of farm animals. The pheromone signals are known to have a potential role in animal reproduction and management. The sources of chemosignals are urine, feces, vaginal secretions, saliva, and specialized scent glands including the odor produced from hair and wool. Pheromones can act as a marker to detect estrus where its detection is a problem and for diagnosing early pregnancy in farm animals. The potential implication of pheromones on improving sexual desire in male is also important. There is huge scope of application of pheromones once it is characterized and synthesized chemically.
