PLACE SELECTION Poultry house should be dry, up
ground & away from locality. Ensure pure water & electricity
supply. Predators & others animal are
not allowed in the farm. Ensure good transport system
for marketing of poultry.
House InstallationHouse should be construct east- west direaction
Having good transport systemEnsure good ceiling system for summer system
Deliver proper ventilation system that remove excess heat
FLOOR SPACEFirst 2 week 0.5 sqft/chick should provided
In summer season 1.2 sqft and winter 1 sqft place should be provided.
BIOSECURITYFarm Metarials: Feeder, waterer, fan, door, window, fan, hover, net should washed following way:
Detergent Washing Soda
Disinfactant
BIOSECURITYFloor: Firstly: Costic Soda- 1.02gm/sqft
Washing Soda- 6gm/ sqftSpray floor & keep 12-18 hrs
Secondly (for 500 sqft)Calcium Carbonate-1000gmBleaching powder- 250 gmCopper Sulphate- 250 gmWater – 5 litreFinally washout the floor
BIOSECURITYFumigation: (for 200 sqft)Potassium per menganate- 40 gmFormalin- 80 gm
Note: Formalin should be putout over PPM
MANAGEMENT IN BROODING
Chick Guard:For 1000 chicks, it should be 24 ft long & 12 ft width
Light: In summer- 1.5 watt/chicksIn winter- 2 watt/ chick
Heat should be provided.
PREPARATION FOR CHICK ARRIVAL Litter material should be spread evenly to a
depth of 3 –4 in (7.5–10cm) and t hen l evel l ed ddd ddddddddd dd ddd br oodi ng ar ea.
The necessar y equi pment must be assembl ed i n t he appropriate configuration as-
Feeder- 30 inch long/ 50 chicksWaterer- 2 litre capacity/ 50 chicks
/
PREPARATION FOR CHICK ARRIVAL Equipment in the house (i.e., fe
eders, drinkers, heaters and fan s) should be arranged to allow c
hicks to maintain body temperat ure without dehydration and to find feed and water easily.
Configuration will depend on th e brooding system and on other
equipment being used.
PREPARATION FOR CHICK ARRIVAL
Supplementary feeders and drinkers shouldbe pla ced in close proximity to t
he main systems.
PREPARATION FOR CHICK ARRIVAL - Houses should be pre heated fo
r a sufficient period to achieve t arget house and litter temperat
ures prior to chick arrival. Temperature should be monitor
ed regularly to ensure a uniform environment exists througho
ut the whole brooding area.
AFTER ARRIVALFirstly provide lukeworm water for 2-3 hrs then provide following solution-Glucose-50gm/ litreMultivitamine-1gm/4 litreElectrolytes- 1gm/ 2 litre
Provide instant energy and restore normal body function.
Note: feed should be supply after 3 hrs on arrival to avoid early enteritis in chicks

FEEDER MANAGEMENTFeeder should keep neat & clean.To treat feeder by disinfactant regularly.
Keep appropriate no. of feeder on basis of population
Provide 24 hrs pure water at daily basis
Use acidifier to control E. coli & salmonella in water.
LITTER MANAGEMENTIn winter season litter should be 2-3 inch & for winter season 4-5 inch depth
Daily spray with disinfactantMoisture level should be keep in minimum level
Moist litter should dry sun heat &treat with surface agnt.

VACCINATIONShould maintain cool chain of vaccineShould be vaccinate at cool environment i.e morning or late night
Diseased or weakness bird should be separate from normal one.
Maintain appropriate route of administration
For better efficacy vaccinate with non fat milk
VENTILATION Air quality is critical during the br
ooding period.Ventilation is required during the
brooding period to maintain temperatures at the targeted level and
to allow sufficient air exchange to prevent the accumulation of har
mful gases such as carbon monox ide, carbon dioxide and ammonia.
VENTILATION Establishing minimum ventil
ation rates from one day of a ge will ensure fresh air is sup
plied to chicks at frequent, re gular intervals.
Stirring fans can be used to maintain evenness of air qua
lity at chick level.
MONITORING EARLY CHICK PERFORMANCE As a result of continued g
enetic gains in growth rat e, brooding has become a
n increasingly greater pro portion of the life of the fl
ock. In addition,
MONITORING EARLY CHICK PERFORMANCES - even day body weight is highl
y correlated to market age weight.
It is strongly recommended that a sample of each flock be weig
hed at seven days to evaluate g rowth performance against stan dards for the given product.
MONITORING EARLY CHICK PERFORMANCE Scales used should be capable of
weighing in 1 g increments. Minimum sample size should be
1 percent of the flock, With sampling done in at least th
ree separate areas of the house. Refer to the attachments for prod
uct weight objectives.
MONITORING EARLY CHICK PERFORMANCEA general rule of thumb woul
d be a - seven day target of 4xdayold chick weight.
Average weights below 130 g should dddd dd dddddddddddd n as to causative reasons.
Seven days weight below 1g release 6g at 42 days.
HUMIDITYdddddddd ddd ddddd ddd d dd ddd
hatcher, at the end of the incubation process will be high (
approx. 80 percent). Houses d ddd whole house he
atingd dddddddddd d dddd dddddd drinkers are used, can have R
H levels as low as 25 percent.
HUMIDITYHouses with more conventi
onal equipment (i.e., spot brooders, which produce mois
ture as a byproduct of comb ustion and bell drinkers, whi
ch have open water surface s) have a much higher RH (u
sually over 50 percent ).
HUMIDITY To limit the shock to the
chicks of transfer from th e incubator,
RH levels in the first thre e days should be maintai
ned near 70 percent.
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 ,C ausing negative effects on perform
ance. In such cases, action should be take
n to increase RH.
HUMIDITY -If the house is fitted with high press
ure spray nozzles (i.e.,foggers) for c ooling in high temperatures, then th
ese can be used to increase RH duri ng brooding.
Chicks kept at appropriate humidity levels are less prone to dehydration
and generally make a better, more u niform start.
HUMIDITY As the chick grows, ideal RH falls.
High RH from 18 days onward can cause wet litter and its ass
ociated problems.As broilers increase in live weig
ht, RH levels can be controlled using ventilation and heating s
ystems.
HEAT STRESS Heat stress negatively affects g
rowth rate and livability. Effects of heat stress can be mi
nimized by altering the environment to reduce the temperatur
e experienced by the bird.
CONTROL OF HEAT STRESS Normal body temperature of a broiler chic
ken is106ºF (41).
Absolute temperature at which a broiler is under heat
stress is related to its age, temperature and.
As a rule of thumb, for fully feathered bird s, a “heat stress index” (RH plus tempera
ture in ºF) of 160 is considered heat stress .
CONTROL OF HEATSTRESS Broilers regulate their body temperatur
e by two methods: radiation/convection of heat and evapora
tive cooling throughrespiration. Within the temperature range 5 5 –7
7ºF (13–25ºC), heat loss is mainly acco mplished through physical radiation an
d convection to the cooler environment.
CONTROL OF HEATSTRESS As the temperature rises ab
ove86ºF(30ºC) t he maj or i t y of hea t loss is accomplished by ev
ddddddddd ddddddd ddd dddddd g, and increased respiration
ddddd
CONTROL OF HEATSTRESS Panting allows the bird to control body t
emperature by evaporation of water fro m the respiratory surfaces and air sacs.
The process uses energy. In conditions o f high humidity, panting is less effective.
Where high temperatures are maintained for long periods, or humidity is very hi
gh, panting may be insufficient to contro l body temperature and the bird may ex
perience heat stress .
CONTROL OF HEATSTRESS As the bird passes into acondition of heat stress, r
ectal temperature rises, h eart rate and metabolic r
ate increase and oxygena tion of the blood decrease
