Reproductive Behaviour involve behaviour patterns associated with courtship, copulation, birth, maternal care and with suckling attempts of newborn. It is species specific behaviour
2. Definition of reproductive
behaviour
Reproductive Behaviour involve
behaviour patterns associated
with courtship, copulation, birth,
maternal care and with suckling
attempts of newborn. It is species
specific behaviour
3. Functions of reproductive behaviour
bring the individual together (male and
female ).
Conservation of the species and for the
continuity of their life.
Synchronize the activities of male and
female ( ova and sperm).
Produce a new progney (selective)
species
It is a species-specific behaviour
6. Definition
Sexual behaviour involves not only the
act of mating, but also all those
elements of courtship, display, motor
activities and postures which have a
unity with coitus to achieve
fertilization and pregnancy .
Each Species has special sexual
behaviour (Species-specific) and
within species there is a differences
between male and female .
7. Components of Sexual behaviour
Precopulatory behaviour
Copulatory behaviour
Postcopulatory behaviour
11. 1-Chemical Communication
(Olfaction & gustatory)
Through sniffing and licking to
The female genital opening
or urine
or the bedding
to detect chemical substance called Pheromones
● Response of the male
(Chin resting behaviour)
Flehmen phenomenon
Camel rises his limb on his neck
●Response of female
Standing behaviour
18. 2-Tactile communication
The male lick and nuzzling the perineal
region of female (sheep, goat, cattle )
In horse: the stallion bites the female at
the neck.
Swine : the male noses the female at
the flank region.
32. Female Pre-copulatory behaviour
(Courtship or Clues(
• The Female in oestrus must provide the
clues (Stimuli( for mating to the male as:
• A-Chemical or Olfactory communication
• B- Visual communication
• C- Auditory communication
• D- Tactile communication
• E- Motor clues( Posture & movement(
33. A-Chemical Clues or
Olfactory Communication
By pheromones (chemical substance )
- She-camel (poll gland)
- Queen (special gland, anal gland)
- male rat detect oesterus female at some
distance by odour.
- male dogs are attracted to the urine of
oesterus bitch.
- Presence of phermones in urine of cattle
34. B- Visual clues or
communication
Chimpanzees
Swelling and reddening of the skin at
the perennial region called sexual skin
38. E-Motor clues( Posture &
movement(
Pro-estrous females show :
increased motor activities restless and
continuous moving
Standing heat in cow
Female lion (lioness) : may crawl up to
and squeeze underneath the lion if he is
not responsive to her advances and odour
41. Male copulatory behaviour
Erection and protrusion of penis
Mounting and fixation
Intromission
Ejaculation and ejaculatory thrust
Dismounting
45. Mounting and fixation
In she camel the mounting occur in sitting position
In cat and Rabbit the male bite the scruff ( behind
the head or at the neck
• Successful mounting
• Mounts ____ fixation of his fore legs around the
female ____ grasp her firmly ___ pelvic thrusts
• False Mounting
58. Intromission
• contraction of the abdominal muscle
(rectus abdomenus) results :
• the direct contact (apposition) of the pelvic
region of male to the female external
genitalia then the intromission occur
(copulation )
60. Ejaculation and ejaculatory
thrust
• reach the os-cervix
in cattle and sheep
• reach the uterus
in horse and swine
• general muscle contraction
in ram, buck, and bull
Dismounting:
penis soon retracted into the prepuce
62. Oestrus pattern
Spontaneous poly-estrus
cow mare she ass
Seasonally :
mono oestrus (bitch)
Di oestrus (queen)
Poly oestrus (ewe, she camel)
Non-spontaneous poly-estrus after coitus
(rabbit, cat, ferret)
63. Oestrus detection
In cow:
Bellowing
Mounting on other cows
Standing heat
Restlessness and excitable
In Mare
Frequent urination
Winking (movement of clitoris)
Straddling posture
64. Oestrus detection
In Ewe:
Teaser Ram
Switching tail
Frequent urination
In Cat
Lordosis
In She-camel
Seek the male
Stand still mounted by male
66. Receptivity and mating by the male
When the male approach the female:
standing heat as in farm animals
The female cat, rabbit, and swine take the
lordosis (Crouched)
- the female stimulated by the male
- arched back, and downward at the center
- bring the chest in contact with the
ground.
- bring the genital region up.
- the tail if present is turned to one side.
70. Male post-copulatory Behaviour
Refractory Period
• Refractoriness:
• Post-coital displays are scarce in domestic animals
• Most animals show sexual inactivity immediately
after copulation
• Ram and bulk in exception usually lick the penis
after ejaculation .
• Cats smell the site of copulation .
• The duration of this period is variable and modified
by environmental stimuli ( 5 min to one hour )
• This period is decreased by changing the female
71. Male post-copulatory Behaviour
• Frequency of copulation :
• Varies with species, breed, ratio of male and
female, climate, and period of sexual rest.
• High No. of ejaculation is in bull and Rams than
Stallion and b Boar.
• Bulls copulate 80 times/ 24 hours
• The bulk, Stallion reach exhaustion after smaller
No. of ejaculation
72. Female post-copulatory Behaviour
Orgasm-Like reaction
• Orgasm-like reaction
• Occur in cow just after copulation
• The cow arches her back and elevate
the tail and keep this urinating
posture for several minutes
73. Female post-copulatory Behaviour
• Post-mating behaviour in Queen:
• As the male withdraws his penis after
ejaculation and due to spines, it cause
pain and the cat make a dramatic cry .
• The cat turn aggressively on the male.
• In case of familiar male, she again rolls
on the floor and licks her vulva .
74. Abnormal sexual behaviour
A- In Male
1- Homosexuality
2- Hypo- & hyper sexuality
3- Inability to copulate
A- Impotence to mount
B- intromission failure
4- Buller-steer syndrome
5-Auto-erotic behaviour
6- False ejaculation
7- Outside ejaculation
75. Buller-Steer Syndrome
This a common health and economic problem in
feedlot operations . The typical buller-steer
sexually attracts his penmates who take turns
following and mounting the abnormal animal.
It does not seem to be associated with rank,
and may be due to boredom. When detected,
bullers are segregated and treated for injury
or illness. Approximately 2% of steers in a
feedlot situation are buller steers
78. Abnormal sexual behaviour
Atypical sexual behaviour, such as
homosexuality, hypersexuality, masturbatory
behaviour, may be caused by genetic flaws,
endocrine imbalances, management
problems, and in many cases may be
reversed .
Masturbation in males is common, especially
in bulls on a high protein diet .
Humans may modify behaviour by processes
such as castration, spaying and endocrine
implants to increase production and ease of
handling .
79. Abnormal sexual behaviour
B- In Female
1- Silent heat
2- Nymphomania
3- Post-partum Anoestrus
4- Mounting humans
5- Delayed puberty
Post-coital dramatic behaviour in
- Dog
- cats
80. Nymphomania
Such cows behave like bulls, pawing and
mounting but refuse to stand for
mounting by other cows. It could be an
inherited trait. It is more common in
high-producing dairy cows than in cows
of beef breeds. Nymphomania is
usually associated with follicular cysts .
