Attractivity Behaviour Among Various Species
- Behaviours and signals that serve to attract males.
- Chemical cues such as pheromones
|Attractivity Behaviour||Increased Locomotion,Increased Vocalisation, Twitching and Elevation of Tail||Increased Locomotion,Tail Erected ('Flagging')||Short period of Restlessness,Ram Seeking||Mild Restlessness||Roaming||Vocalisation ('Calling')|
- Secretions from the female reproductive tract that serve to sexually stimulate and attract males to the female.
- Vaginal and urinary secretions from females in Oestrus smell different to the male then secretions of females not in Oestrus.
- Pheromone is a volatile substance released to the outside of the body and perceived by the olfactory system and/or activated by the vomeronasal organ. Releasing pheromones can cause specific behaviour in the recipient.
- Males also produce sex pheromones.
- Boars produce specific substances that cause sows and guilts to become sexually aroused when they are in Oestrus.
- Two sexual attractants are produced by boars:
- Preputial pouch secretion
- Pheromonal substance in saliva secreted by the submaxillary salivary gland.
- During sexual excitement, the boar produces copious quantities of foamy saliva. The active components in saliva are the androgen metabolites 3α-Androstenol and 5α-Androstenone. Both have a musk-like odour.
- In many species, sexual readiness is accompanied by some form of unique vocalization ('mating call').
- Elevated vocalization alerts/signals to males that sexual readiness is imminent.
- Auditory stimulus is more useful in long-range stimulation than close discrimination.
- All females display a form of sexual posturing that can be perceived by males.
- Can be subtle to human observers.
- Identification of postures takes place easily among members of the same species.
