Causes And Control of Early Chick
Mortality

4. CONTENTS
• Introduction
• Causes
• Genetic causes.
• Managemental causes.
• Nutritional causes.
• Disease causes
• Control

5. INTRODUCTION
• Chicks are very fragile during the first few weeks of
their life so sound management & other measures
should be adopted to keep the flock healthy otherwise
it can cause the mortality of baby chicks
• A mortality of 1-5% should be considered
normalanything higher than this should alarm the
farmer

7. CAUSES OF EARLY CHICK MORTALITY
• There are enormous causes of early chick mortality, Some are
listed below
• Genetic causes.
• Managemental causes.
• Nutritional causes.
• Disease causes.

8. GENETIC CAUSES
• Genetic cause is also important because there are 21 lethal
mutations in the fowl.
• The greater the abnormality caused by the lethal gene, the
earlier the age at death.
• Sticky embryos die during the last 4 days of incubation and
about half of the Naked chicks die during 2 or 3 days before
hatching time

9. MANAGEMENTAL CAUSES
• Effect of high brooding temperature High brooding
temperature causes the following problems,
• Dehydration: When the water loss from the body reaches
above the 10% the chicks die. Actually the young chicks
comprises 70% water
• Pasting: It’s the condition in which the feces are stalked
around the vent area causing blockage of the vent which
ultimately results in death.

10. MANAGEMENTAL CAUSES
• Effect of low brooding temperature Low brooding
temperature causes the following problems:
• Chilling or brooding pneumonia
• Smothering
• Effect of poisoning Mortality due to poisoning is also
high in young chicks such as:
• Feed poisoning

11. • Salt poisoning
• Gas poisoning
• Other managmental problem like
• Ammonia
• Carbon monoxide
• Effect of injuries
• Starvation

12. NUTRITIONAL CAUSES
• Water: Water play an important role in maintaining the health
and performance of the birds. Imbalance and unhygienic water
causes high mortality.
• Effect of fat soluble vitamins deficiency
• Effect of water soluble vitamins deficiency

13. DISEASES
• Omphalitis:
• This bacterial disease affects the chicks during and after
hatching, spreads navel infection characterized by inflamed
skin in the navel area, soft, flabby and distended abdomen,
vent pasting, foul smelling on carcass opening, due to
unabsorbed yolk.

14. DISEASES
Salmonellosis: A group of acute rapidly spreading diseases
affecting all ages characterized by rise in body temperature,
septicemia, omphalitis, hepatitis, enlargement of spleen, arthritis
and death.
Colibacillosis: It is an acute septicemia disease caused by E-coli
affecting all ages characterized by involvement of all systems,
poor feed conversion and death.
Air sacculitis:Congested lungs and liver and air sacs.

15. Pullorum: it is an acute infectious and fatal
bacterial disease of chicks characterized by
ruffled feather, white diarrhea, labor breathing,
chirping and death

16. CONTROL OF EARLY CHICK MORTALITY
• To prevent the problems of dehydration, pasting, chilling and
smothering we should adjust the brooding room temperature
24 hours before putting the chicks in the brooding room and
during the brooding period. Try to maintain the normal
temperature throughout the brooding period and brooding
areas
• Avoid over crowding of chicks by giving proper floor, feeder
and waterer spaces
• To prevent genetic disorders we have to choose a good breed
and proper breeder management should be adopted to control

17. CONTROL OF EARLY CHICK MORTALITY
• We have to adapt proper measures to overcome the nutritional
disorder
like: dehydration , vit. Deficiency etc
• To prevent genetic disorders we have to choose a good breed
and proper breeder management should be adopted to control
vertically transmitted diseases
