Animal Mating Behaviour

What are the 8 types of teasing by male?

• Smelling and licking vagina

• Smelling of female urine

• Flehmen’s response (open mouth response to the urine of receptive female)

• Muffling rump at perineum area

• Biting neck (mare)

• Muffling at posterior (ram)

• Frothing (boar)

• Grunts

What are the 8 types of teasing by female?

• Restless

• Make noise

• Smell the male groin and penis

• Directing posterior towards male

• Mock fighting

• Frequent urination

• Mounts other females (goats, cows, pigs)

• Flickers tail frequently (goats, sheep)

Erection

• What type of stimulation

• What occurs to artery

• Penis becomes

• In ruminants, man and boar the extension is accomplished by

• What occurs to sigmoid flexure

• What occurs to retractor muscle

What type of stimulation: Parasympathethic

What occurs to artery: Vasodilatation of artery to supply blood to cavernosum body

Penis becomes:

• Turgid and straight

• Exposed as prepice everts

In ruminants, man and boar the extension is accomplished by: Slight dilation

What occurs to sigmoid flexure: Stretches

What occurs to retractor muscle: Relax

Mounting

• What occurs

• Failures occur when

• What is intromission

• Pelvic thrusts assisted by

• Failures of intromission causes

What occurs:

• Female stand still

• Female doesn’t reject male

• Male aligns the body

• Male mounts from behind

• Fore limb holds the female

• Push at pelvis is rhythmic

Failures occur when: There are injuries, weakness or soreness in the hind-limbs of males

What is intromission: Introduction of the penis into the vagina and its maintenance within the vagina

Pelvic thrusts assisted by: Abdominal muscles

Failures of intromission causes:

• Phimosis (constriction of preputial orifies)

• Hematoma of penis

• Congenital deformities

Emission and Ejaculation

• As sexual stimulation increases, what occurs

A point is reach at which reflex centers in spinal cord bring out emission and ejaculation

Withdrawal

• What occurs if its unsuccessful

• What occurs if its successful

Unsucessful: Dismounts and tries again

Successful:

• Dismounts from back of female

• Penis is flaccid and semen trickles

• Lick the glands penis to clean

• Female arches back to create low pressure in uterus so semen is sucked up

• Adpots urination position to clean vagina

Sexual characteristics influenced by

• Hormones of

  • Female characters

  • Male characters

• Sensory organs function

• Auditory function

• Visual function

• Tactile function

• Hypothalamic

Hormones of:

• Female characters: Estrogen and progesterone

• Male characters: Testosterone

Sensory organs function: Smell pheromones present in urine and discharge

Auditory function: Can identify characteristics call of opposite sex

Visual function: Vision of opposite sex

Tactile function: Touched by opposite sex

Hypothalamic: Impulsive reaction to stimulus of nerves and hormones
