Brooding Management Flashcards
most crucial and important stage in poultry
brooding
goal of brooding
to maximize the growth and survival of the chicks by enhancing the immune, digestive, skeletal, and muscular system development.
first __ days of life, the chicks adjust from the hatcher incubator to farm conditions
7
this is the period where chicks are placed in an area where heat is supplied until they are able to regulate their body temperature
brooding
why is heat supplemented during brooding?
chicks are unable to regulate their body temp yet
chicks are ___-_________ which means their body temperature regulation is partially dependent on external environmental conditions
semi-poikilotherms
parts of brooder setup
- brooder guard
- hover/heater
- litter material
- waterer
- feeder
true or false
newborn chicks are more hungry than thirsty
false; they are more thirsty
chicks are supplied with ___ hours of light
24 hours
ideal temperature in the first week of brooding
31-32 degree Celsius
the temperature in the first week of brooding is reduced by 2 degree Celsius per week
true or false
true
temperature in brooding is maintained at __-__ degree Celsius
21-24
how to know if the temperature set for brooding is okay?
check the physiological behaviors of the chicks
indicators - temp
constantly cheeping chicks evenly spread
just right
indicators - temp
noisy chicks huddled together away from draught
too draughty
indicators - temp
when drowsy chicks spread around the perimeter, it means it’s too cold
true or false
false; it’s too hot
indicators - temp
noisy chicks huddled under broiler
too cold
upon arrival in the farm, chicks are introduced to booster feeds in _______ _________ form under __ ________ feeding system
micro pellet; ad libithum
booster feeds should supply ___% CP and _____ kcal/kg of metabolizable energy
22% and 3100 kcal/kg
why is light important to be available 24 hours per day?
it allow the chicks to easily locate the feeders and waterers all day
effects of overcrowding
- stunted growth
- poor flock uniformity
- cannibalism
how is cannibalism prevented?
trimming of the beak (brooders only)
length of brooding depends on
- rate of feathering
- season
brooding is longer if the feathering rate is faster
true or false
false; it is longer if feathering rate is slower
in summer, brooding is ________ (shorter, longer)
shorter
management practices during brooding
- provision of temp
- ” right type and amount of feeds
- ” clean drinking water
- ” amount of light
- ” proper floor space
beak treatment is being done during the first ___ days post-hatch
10 days
nasty habit of toe and feather pecking in birds
cannibalism
goal of maintenance phase
to control the growth of the birds to skeletal and muscular development only to promote excellent body conformation prior to sexual maturity
external source of heat is no longer needed in the maintenance phase
true or false
true
internal mechanism of birds that allows them to regulate their own body temperature
thermoregulatory mechanism
photoperiod in maintenance phase should not exceed ___ hours/ day
12
excessive light in maintenance phase promotes?
premature development of the reprod system and could result in early laying of eggs
feeding system in maitenance phase is ad libithum
true or false
false; feeding system in maintenance phase should be restricted
2 forms of food restriction
- quantitative
- qualitative
2 forms of food restriction
in qualitative, what is reduced?
nutrient density of the feed offered (increase in fiber content)
early development of reprod system in maintenance phase can result in
- too small eggs
- short prod cycle
- prolapse
