Midterm 3 - Lecture 20 Flashcards
When do stages of repro behaviour occur in males?
can occur at any time
When do stages of repro behaviour occur in females?
sexual activity confined to estrus
What are the 3 stages of repro behaviour in males?
Precopulatory stage
Copulatory stage
Postcopulatory stage
What are the 3 stages of repro behaviour in females?
- attractivity
- proceptivity
- receptivity
What is the sequence of events for precopulatory behaviour in males?
search for sexual partner
courtship
sexual arousal
erection penile protrusion
What is the sequence of events for copulatory behaviour in males?
mounting
intromission
ejaculation
What is the sequence of events for postcopulatory behaviour in males?
dismount
refractory period
memory
Flehman response
in the presence of females, the male will lift their upper lip to expose the vomeronasal organ which is a bypass directly into the sinuses to help them detect pheromones when they are present
What are ‘warm-up’ stalls? What are they used for?
- stimulate sexual behaviour
- if you want to collect semen (AI), have to create enviro to stimulate males even if female isn’t present
- bulls waiting; stimulated by lots of visuals
Female sexual behaviour - attractivity
- behaviour and other signals that attract the male
- locomotion, postures (lordosis), vocalization, pheromones (in urine)
Lordosis
female turns hindquarters to male, arching of back, deviation of tail
Female sexual behaviour - proceptivity
- behaviours by the female towards the male to stimulate copulation
Female sexual behaviour - receptivity
- copulatory behaviour (stance) by the female
- ‘subcoming’ to the mating process
How is physical activity related to estrus?
- female in estrus are moving around more which increases the likelihood they will interact with the male
What is reproductive behaviour controlled by?
the CNS
