| − | === Female ===
| |
| − | | |
| − | * 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 Behaviour - Anatomy & Physiology|Oestrus]] smell different to the male then secretions of females not in [[Oestrus Behaviour - Anatomy & Physiology|Oestrus]].
| |
| − | * Pheromone is a volatile substance released to the outside of the body and perceived by the olfactory system and/or activated by the [[Pre-copulatory Behaviour - Anatomy & Physiology#Vomeronasal_Organ|'''vomeronasal organ''']]. Releasing pheromones can cause specific behaviour in the recipient.
| |
| − | | |
| − | === Male ===
| |
| − | | |
| − | * Males also produce sex pheromones.
| |
| − | ** '''Boars''' produce specific substances that cause sows and guilts to become sexually aroused when they are in [[Oestrus Behaviour - Anatomy & Physiology|Oestrus]].
| |
| − | ** Two sexual attractants are produced by boars:
| |
| − | *** '''Preputial pouch secretion'''
| |
| − | *** '''Pheromonal substance in [[Salivary Glands - Anatomy & Physiology#Saliva|saliva]]''' secreted by the submaxillary [[Salivary_Glands_-_Anatomy_&_Physiology#Types_of_Salivary_Glands|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.

| − | == Auditory Signals ==
| |
| − | | |
| − | * In many species, sexual readiness is accompanied by some form of unique vocalization ('mating call').
| |
| − | ** Cows increase bellowing during [[Oestrus Behaviour - Anatomy & Physiology|Oestrus]].
| |
| − | ** Sows display characteristic grunting associated with [[Oestrus Behaviour - Anatomy & Physiology|Oestrus]].
| |
| − | ** Queens often 'yeow' repeatedly to call the tom.
| |
| − | ** Mares and Ewes are comparitively silent.
| |
| − | * Elevated vocalization alerts/signals to males that sexual readiness is imminent.
| |
| − | * Auditory stimulus is more useful in long-range stimulation than close discrimination.

| − | == Visual Signals ==
| |
| − | | |
| − | * 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.
