| + | == 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 [[Lips|lip]]. |
| + | * Fluid-borne, less volatile chemicals enter the vomeronasal organ through the [[Alimentary_- Anatomy & Physiology#Oral_Cavity|oral cavity]] by means of nasopalatine (incisive) ducts. |

| + | * Some [[Attractivity Behaviour - Anatomy & Physiology#Pheramones|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 [[Attractivity Behaviour - Anatomy & Physiology#Pheramones|pheromones]] and will nuzzle the female genital region. |
| + | * Flehmen behaviour is characterized by: |
| + | ** Head elevation |
| + | ** Curling of the upper [[Lips|lip]]. |
| + | * Curling of the upper [[Lips|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 - Anatomy & Physiology|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. |
