17
Q

indicators - temp

noisy chicks huddled under broiler

A

too cold

18
Q

upon arrival in the farm, chicks are introduced to booster feeds in _______ _________ form under __ ________ feeding system

A

micro pellet; ad libithum

19
Q

booster feeds should supply ___% CP and _____ kcal/kg of metabolizable energy

A

22% and 3100 kcal/kg

20
Q

why is light important to be available 24 hours per day?

A

10 days

28
Q

nasty habit of toe and feather pecking in birds

A

cannibalism

29
Q

goal of maintenance phase

A

to control the growth of the birds to skeletal and muscular development only to promote excellent body conformation prior to sexual maturity

30
Q

external source of heat is no longer needed in the maintenance phase

true or false

A

true

31
Q

internal mechanism of birds that allows them to regulate their own body temperature

A

thermoregulatory mechanism

32
Q

photoperiod in maintenance phase should not exceed ___ hours/ day

A

12

33
Q

excessive light in maintenance phase promotes?

A

premature development of the reprod system and could result in early laying of eggs

34
Q

feeding system in maitenance phase is ad libithum

36
Q

2 forms of food restriction

in qualitative, what is reduced?

nutrient density of the feed offered (increase in fiber content)

37
Q

early development of reprod system in maintenance phase can result in
