ةـــــموملاا كولس

3. Definition (Concepts) of
maternal behaviour

That behaviour exhibited by mothers towards
their young to aid their survival, growth and
development, both physically and behaviorally.
It is inherited behaviour

Maternal behaviour in mammals (suckling
animals) exhibited by mother toward their
young, including feeding, protection, warming
growth, development and survival.



Parental behaviour exhibited by both male and
female as in pigeons and other birds.

4. Classifications of Maternal
behaviour

1-According to No.of youngs /
birth

Polytocus Animals

Monotocus Animals

2- According to Nature of youngs:

Precocial young

Altracial young

5. Classifications of Maternal
behaviour

3- According to Following dams :

Follower Animals

Hider Animals

Intermediate Animals

4- According to stage of parturition:

Pre-parturient behaviour

Parturient behaviour

Post-parturient behaviour

6. Polytoccus Animals
Mother give birth to more than one
or two youngs e.g. dog, cat, rate,
mice, hamster.
Characters of their young ( altracial young )
1- immature young
2-helpless at birth
3-sealed eye and
4- Sealed ears until 2-3 weeks

7. Characters of their young ( altracial young )
5-imobile( crawl around the dam)
6-cannot eliminate them selves
7-cannot regulate their body temp.
8-They have no teeth (smooth gum)
9-hairless
10-depend completely on their dam
in feeding, warmth, protection and
elimination.

8. Polytoccus Animal (rat & mice)
(altracial young)

9. Polytoccus Animal (cat)
(altracial young)

10. Monotoccus Animals

Mother give birth to one or two young

e.g. cattle, horses, sheep, goat,
camel.

Characters of their young (precocial young)

relatively mature young

opened eye

opened ears

11. Characters of their young
(precocial young)



5- can eliminate themselves

6- can regulate their body temp.

7- they have a teeth

8- body covered with hair

9- depend partially on their mother in
feeding and protection.

12. Monotoccus Animals
(precocial young)

13. 3 -According to Following dams

Follower Animals

Hider Animals

Intermediate Animals

14. Follower Animals

Young spent most of time within a
very short distance of the mother to
be more safe

e.g. cattle, sheep, horses

in horse the young follow their
mother until grow older

15. Follower Animals

16. Foal follows his Dam

17. Follower sheep (Protection)

18. Hider Animals

The kid is hidden for as long as eight
hours while the mother feed. after 5
days the kid stay with mother when
she feed

e.g. goat

19. A Kid hides while another suckles

20. Intermediate Animals
Called Clinging species
e.g. Chimpanzees

22. A- Maternal behaviour in
Monotoccus Animals

Pre-parturient behaviour

Parturient behaviour

Post-parturient behaviour

23. Pre-parturient behaviour
Restlessness
Signs of pain looking and kicking at the flank (Mare)
In Ewe vicious, pawing to the ground
Vocalization increased
Isolation from the herd to avoid disturbance
Early maternal interest( lamb and calf stealing)
Getting up and lying down
Rolling on the ground (Mare and cats)
Rubbing to any fixed objects
Cessation of rumination (Cow-ewe)

24. Lamb or calf stealing

It is high maternity

It occurs in group housing animals

as the parturition approached the
pregnant female showing early
maternal interest to the young of
other females that give birth in vicinity
she may care it and this called lamb
stealing

25. Pre-parturient behaviour in mare
Mares isolate themselves from the
herd mates
1 month prior:mammary gland begins
to enlarge and ventral edema

2 days prior: udder distended,
secretion changes to colostrum

24 hours prior: waxing of teats

4 hours prior: drips milk

•Expulsion of placenta take 30 min. to six
hours.
•Eating of placenta called
Placento-phagia.
•Eaten in cow and buffalo
•Mares doubtful
•Not occur in she camel

46. Expulsion of placenta

47. Post-parturient behaviour

Mother (dam) behaviour

Newly born behaviour

Mother-infant bond

Recognition

48. Behaviour of the dam

Standing of dam immediately
after birth

Maternal grooming of newly born

Maternal imprinting and
recognition

Eating placenta (placento-phagia)

49. Maternal imprinting and
recognition

Rapid, stable, irreversible learning
occur shortly after birth
( immediately) within a period called
critical period or sensitive period .

The young follow its mother and the
mother- young bond is formed
through labeling and recognition.

50. Maternal grooming of newly born

immediately, begins by the head,
body then limbs and hind parts

Functions of licking

1-dryness of young body.

2-removal of fetal fluid from nostril and
mouth to stimulate respiratory center

3-stimulation of cut, blood, lymph
circulation.

51. Functions of licking (cont.)

4- help to stand.

5- facilitate urination and defecation.

6- increase muscular tone.

7- labeling of young and recognition.

8- aid in the formation of maternal
filial bond.

52. Licking Behaviour
•Social Licking
1.Promotes maternal-
offspring bond and
social bond among
herd members
2.Directed mainly to
the head and neck
of the calf
•Maternal Licking
1.It is designed to
stimulate calves to
eliminate wastes
(Urination and/ or
defecation)
2.Directed mainly to
the perineum region
of the calf

53. Maternal licking by a cow

54. Maternal licking by a buffalo cow

55. Social Licking by cow

56. Wet calf stimulate licking in cow

57. Licking by Mare

58. •Foal has completely delivered but the
placenta is still attached

59. Eating placenta (placento-phagia)
Function of Placentophagia :
1-Contain hormones as estrogen, progesterone and
prolactine that important for milk yield
2-defence against predators by removing the odour
3-hygienic measures prevent micro-organism
4 -affect on maternal immune response as it contain
factors prevent the formation of antibodies
against fetal antigen which might impair
subsequent pregnancies.
5 -Recycling of nutrients (Protein and minerals)

60. Behaviour of the Newly born

1- Standing behaviour

2- Udder searching or Teat seeking

Suckling behaviour

61. Standing behaviour

1- coordinating recumbence
behaviour

2- elevation behaviour

3- ambulation behaviour

4- environmental exploration

5- udder searching behaviour

6- suckling behaviour

64. elevation behaviour in buffalo
(upright equilibrium or 1
st
standing)

65. elevation behaviour
(upright equilibrium)

66. ambulation behaviour
(attempt of young to walk)

67. Udder searching or Teat
seeking

Newly born directed to the wrong
parts of the body in the 1st attempts
of suckling

Guides of the calf to find teat may be

1- the pendulus shape of the udder

2- the movement of udder (udder tilting)

3- temperature between thighs
(thigmotaxis)

68. Udder searching behaviour

The mother also help the calf to find
teats by:

1- rotating her body

2- abduction the hind legs

3- moving forward bringing the udder
closer to the calf

4- licking the perineal region to stimulate
the calf to suckle

71. Suckling behaviour

Posture of suckling

Mechanism of suckling

Rate and frequency of suckling

Non-nutritional suckling

Difference between sucking and
suckling behaviour

72. Posture of suckling
•Typical posture is the young stands
alongside the mother facing caudally
•There is often no teat preferences for front
or hind teats
•Abnormal posture may be
–1- rear suckling
–2- the calf stay in right angle with mother body
( perpendicular suckling)

73. Mechanism of suckling
The calf grasp the teat with its mouth and
sucks vigrously
It develops negative pressure by warping
thetongue around the teat
It forms an air- tight compartment in oral
cavity which is necessary for milk flow
- the calf butts the udder with its head in
buffalo
- tail wagging and peaceful suckling

85. Pre-parturient behaviour
In dogs and cats
- Licking of genital and abdominal areas 12-24
hours before labour.
- drop in body temp
- squatting posture as in defecation
Scratching of ground
- nest building is not pronounced
- bedding for kittening or whelping is provided by
owner
While in dogs it scratch rugs or towels and blanket

Plucking Hair from body (neck, thigh,
abdomen and back) to build maternal nest
few days before part. to maternal nest
- increase restless, vocalization.

 Loss Appetite

89. Nest building In rabbits

90. Parturient behaviour

1st stage

-uterine contraction

-lying down during this stage

-straining

91. 2nd stage

-abdominal contraction

- the mother consume the fetal
membrane as the fetus passed and
licking them.

92. 3rd stage

- delivering of placenta and readily eaten by
mother


Functions of placentophagia

-keep the nest clean and free from

material which may attract bacteria.

2-Some nutritive value to the mother protein
and water allow her
to stay in nest with her young.

93. Post-parturient behaviour

94. Grooming of the young

1st three weeks of life the dam licks
and grooming each new born .

grooming directed to ano-genital
region to stimulate urination and
defecation .

Fecal material consumed by mother
to keep nest clean

95. Nursing- sucking
development
Mother young interaction occur in
3 stages

96. 1st stage
from birth to 2.5 weeks (14 to 17 days)
mothers play the major role in nursing,
licking ,nursing and suckling of young
Mother initiates nursing by hovering
over the litter & arousing them to
nursing by licking them
The young nuzzle into fur of mother,
find a teat & nurse

97. 2nd stage

From 3 weeks –5 weeks of age

open eye and ears

can leave the nest, recognize and
interact with mother outside the nest

young here initiate suckling

While mother facilitate suckling by
exposure nipple

98. 3rd stage

From 5 weeks – weaning

young are able to take food from
other source

nursing initiated and completed by
young

99. Nipple exploratory behaviour

tactile cues (Texture of nipple )

olfactory cues

In dog, cat through saliva

109. Stimuli elicit maternal behaviour
 odour and taste: the presence of birth
fluid Stimulate licking
Vocalization (distress calls) mother
distinguish young from calls

altracial inaudible calls while Precocial
audible calls.
 Stimuli emanating at suckling :
thermal contact or tactile stimuli

Sniffing & licking them at suckling due to
butting nuzzling by young.

110. Stimuli elicit maternal behaviour

Movement : newly born activity
specially during suckling

Vigor or strong newborn stimulate dam
to lick him


●
shape of the young (visual stimuli)

●protective response: defence
against predators to protect young.

125. Abnormal maternal
behaviour
Miss-mothering behaviour
This may be due to the mother having
suffered a long and difficult birth and not
being able to stand up for suckling. The
calf may also be too weak to suckle. Cases
of mismothering are common with cows
calving in synchrony in intensively
managed maternity groups.
