Poultry farms and evaporative
cooling cell padsÂ
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.Â
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).Â
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.Â
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:Â
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:Â
Bad conversion ratio
in the broilers, low quantity and quality in egg production, and
bad fertility and hatchability.Â
Complications
resulting from high temperature:
- Respiratory
diseasesÂ
-
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.
