This document provides information on broiler chicken management. It discusses topics like house preparation, brooding management, water and litter management, vaccination schedules, and heat stress control. Key points include maintaining proper temperatures and humidity for chicks, using litter depths of 2-3 inches in winter and 4-5 inches in summer, vaccinating for diseases like ND and IBD, and controlling heat stress through ventilation and cooling to reduce heat index below 160. Monitoring early chick performance through weekly weighings is also recommended.

16. PREPARATION FOR CHICK
ARRIVAL
Litter material should be
spread evenly to a depth o
f 3–4 in (7.5–10 cm) and t
hen levelled and compacte
d in the brooding area.
The necessary equipment
must be assembled in the
appropriate configuration
as-

17. PREPARATION FOR CHICK
ARRIVAL
 Equipment in the house
(i.e., feeders, drinkers, heate
rs and fans) should be arran
ged to allow chicks to mainta
in body temperature without
dehydration and to find feed
and water easily.
 Configuration will depend
on the brooding system and
on other equipment being us

18. PREPARATION FOR CHICK
ARRIVAL
 Supplementary feeders
and drinkers shouldbe pla
ced in close proximity to t
he main systems.

19. PREPARATION FOR CHICK
ARRIVAL
Houses should be pre-heated
for a sufficient period to achieve
target house and litter temperat
ures prior to chick arrival.
Temperature should be
monitored regularly to ensure a
uniform environment exists thro
ughout the whole brooding area
.

35. VENTILATION
Air quality is critical during the
brooding period.
Ventilation is required during
the brooding period to maintain
temperatures at the targeted lev
el and to allow sufficient air exc
hange to prevent the accumulati
on of harmful gases such as car
bon monoxide, carbon dioxide a
nd ammonia.

36. VENTILATION
Establishing minimum
ventilation rates from one
day of age will ensure fres
h air is supplied to chicks
at frequent, regular interv
als.
 Stirring fans can be used
to maintain evenness of ai

CHICK PERFORMANCE

38. MONITORING EARLY CHICK
PERFORMANCE
As a result of continued
genetic gains in growth ra
te, brooding has become a
n increasingly greater pro
portion of the life of the fl
ock. In addition,

39. MONITORING EARLY CHICK
PERFORMANCE
Seven-day body weight is
highly correlated to market a
ge weight.
 It is strongly recommended
that a sample of each flock b
e weighed at seven days to e
valuate growth performance
against standards for the giv
en product.

40. MONITORING EARLY CHICK
PERFORMANCE
Scales used should be
capable of weighing in 1 g in
crements.
Minimum sample size
should be 1 percent of the fl
ock,
 With sampling done in at
least three separate areas of
the house.

41. MONITORING EARLY CHICK
PERFORMANCE
A general rule of thumb
would be a seven-day target
of 4x dayold chick weight.
 Average weights below 130
g should prompt investigatio
n as to causative reasons.
Seven days weight below 1g
release 6g at 42 days.

42. HUMIDITY
Relative humidity (RH) in the
hatcher, at the end of the inc
ubation process will be high
(approx. 80 percent).
 Houses with whole house
heating, especially where nip
ple drinkers are used, can ha
ve RH levels as low as 25 per
cent.

43. HUMIDITY
Houses with more
conventional equipment (i.
e., spot brooders, which p
roduce moisture as a bypr
oduct of combustion and
bell drinkers, which have
open water surfaces) have
a much higher RH (usually
over 50 percent).

44. HUMIDITY
To limit the shock to the
chicks of transfer from the
incubator,
RH levels in the first three
days should be
maintained near 70 perce
nt.

45. HUMIDITY
RH within the broiler house
should be monitored daily.
If it falls below 50 percent in
the first week, chicks will begin
to dehydrate,
Causing negative effects on
performance.
 In such cases, action should be
taken to increase RH.

46. HUMIDITY
If the house is fitted with
high-pressure spray nozzles
(i.e.,foggers) for cooling in hi
gh temperatures, then these
can be used to increase RH d
uring brooding.
Chicks kept at appropriate
humidity levels are less pron

47. HUMIDITY
As the chick grows, ideal
RH falls.
 High RH from 18 days
onward can cause wet litte
r and its associated proble
ms.
As broilers increase in live
weight, RH levels can be
controlled using ventilatio

48. HEAT STRESS
Heat stress negatively affects
growth rate and livability.
 Effects of heat stress can be
minimized by altering the enviro
nment to reduce the temperatur
e experienced by the bird.

49. CONTROL OF HEAT
STRESS
Normal body temperature of a
broiler chicken is 106ºF
(41ºC).
Absolute temperature at which a
broiler is under heat
stress is related to its age,
temperature and RH.
 As a rule of thumb, for fully
feathered birds, a “heat stress inde
x” (RH plus temperature in ºF) of 16
0 is considered heat stress.

50. CONTROL OF HEAT
STRESS
Broilers regulate their body
temperature by two methods:
radiation/convection of heat and
evaporative cooling through
respiration.
 Within the temperature range
55–77ºF (13–25ºC), heat loss is
mainly accomplished through p
hysical radiation and convection
to the cooler environment.

51. CONTROL OF HEAT
STRESS
As the temperature rises
above 86ºF (30ºC) the majori
ty of heat loss is accomplish
ed by evaporative cooling an
d panting, and increased res
piration rate.

52. CONTROL OF HEAT
STRESS
Panting allows the bird to
control body temperature by ev
aporation of water from the res
piratory surfaces and air sacs.
The process uses energy. In
conditions of high humidity, pa
nting is less effective.
 Where high temperatures are
maintained for long periods, or
humidity is very high, panting m

53. CONTROL OF HEAT
STRESS
As the bird passes into a
condition of heat stress, r
ectal temperature rises, he
art rate and metabolic rate
increase and oxygenation
of the blood decreases.
