Poultry farms and evaporative
cooling cell pads
To minimize heat stress,
effective cooling management is important for growers to achieve
maximum weight gains and optimum feed conversion while preventing
bird loss due to heat exhaustion. RDER evaporative cooling cell
pads have become popular solutions in hot climates like Egypt and
the Middle East and is the primary evaporated cooling system
currently installed. Depending on environmental conditions
(temperature, humidity), incoming air temperature can be lowered
*0 to *0 degrees Celsius.
The optimum temperature
for the adult birds varies between *7 to *8°C and in that range
we can obtain the optimum production (meat and
eggs).
The body temperature of
an adult chicken is (*0.6 to *1.7°C). The thermo neutral zone is
(****8°C), which allows chickens to maintain their body
temperature. If the temperature is above this zone, heat must be
lost in some way as chickens have no sweat glands. Since eating
increases body temperature, chickens reduce their feed intake
during hot weather, and therefore gains will be less. Chickens
begin panting at (*0°C) to help dissipate heat, and drink more to
avoid dehydration.
A combination of high
temperature and high humidity is a problem, because panting does
not cool them under these conditions. Fast-growing broilers are
particularly susceptible to heat stress due to their high level
of production. Producers should provide abundant cool drinking
water in close proximity to the birds inside and
outside.
Increasing the
temperature above *8 °C reveals symptoms such
as:
Reduction in feed intake
with slight increase in water consumed by birds. This will affect
feed conversion and increase water intake. This will lead to
ruining of litter, in addition to the disturbance of electrolyte
balance in the body, which can lead to death.
Panting accelerated
breathing affects the respiratory tract (dryness and congestion).
This will result in making the respiratory system more
susceptible to viral and bacterial infection. Carbon Dioxide
expelled more than normal, will result in reduction of
carbonates, which is the most important portion in forming
eggshell. Carbon Dioxide plays an important role in keeping blood
acidity as shortage of Carbon Dioxide will lead to alkalinity,
which is fatal.
Mortality: the symptom
of mortality begins at *5 °C especially in the well-matured birds
(heavy weight). The effect of high temperature will be aggravated
and it is inconceivable to have a living bird at *7
°C.
Economical losses from
high temperature:
Bad conversion ratio in
the broilers, low quantity and quality in egg production, and bad
fertility and hatchability.
Complications resulting
from high temperature:
- Respiratory
diseases
-
Coccidia
- Electrolytes and
vitamins deficiencies. These are needed in heat stress especially
vitamin C
- Immunological
disturbance, which leads to reconsideration of vaccination
program
It is difficult to
evaluate mortality with accuracy, but high temperature can lead
to economic disaster.
