Tactile Stimulation
- Tactile stimuli from males is important in provoking sexual postures or standing postures by females.
- Stallion: Bites the neck or withers of the mare
- Tom: Bites the neck of the Queen
- Bull: Chin rests on the back of the cow just prior to mounting
Vomeronasal Organ
- Vomeronasal organ is an accessory olfactory organ.
- Connected to two small openings in the anterior roof of the mouth just behind the upper lip.
- Fluid-borne, less volatile chemicals enter the vomeronasal organ through the oral cavity by means of nasopalatine (incisive) ducts.
Flehmen Response
- Some pheromones are less volatile and need to be detected by the vomeronasal organ.
- Bull, ram, stallion, some extent the boar.
- Male closely approaches the source of pheromones and will nuzzle the female genital region.
- Flehmen behaviour is characterized by:
- Head elevation
- Curling of the upper lip.
- Curling of the upper lip closes the nostrils and allows negative pressure to form in the nasopalatine duct.
- Flehmen behaviour allows less volatile pheromones to be examined by sensory neurons in the vomeronasal organ.
- As in the males, females will display flehmen to novel compounds such as fluids associated with the placenta, newborn animals and other volatile materials.
- Frequently displayed by post-parturient females as they make identity discriminations between their own versus other's neonates.
