25
What is the proper handling of stored eggs
Pointy end down
26
It also removes be protective cuticle making the egg more susceptible to contamination
Washing
27
What are the requirements of successful incubation
Location Sanitation Calibration Proper temperature Humidity Correct position of the eggs Turning Adequate ventilation Moisture loss Biosecurity measures
28
Is an act of bringing an egg to hatching and it refers to the development of embryo within the egg under favorable environmental condition
Incubation
29
What are the types of incubation method
Broad hand incubation method for natural incubation Artificial incubation
30
What are the types of incubators
Based on air circulation Based on size Based on stages Based on heating source
31
What kind of incubator are in the BASED ON AIR CIRCULATION
Still air incubator Forced draft incubator
32
What are the types of incubator are in the BASED ON HEATING SOURCE
Hot air incubator Hot water incubator
33
What are the kinds of incubator are in the BASED ON SIZE
Cabinet or mammoth incubator Walk in incubator
34
What are the kinds of incubator are in be BASED ON STAGES
Single stage incubator Multi stage incubator
35
This is a type of incubator that is a simple type of box in which no fun is provided mostly used in villages in domestic level temperature is maintained by the thermostat at around 102 small poles are made for air ventilation
Still air incubator
36
This kind of incubator is the air is force with the help of a fan and drafted air is uniform distributed temperature remains constant in each egg for the control of temperature heater of thermostat is provided and even coil heating mechanism is used
Force draft incubator
37
This kind of incubator contain setter and hatcher in a single chamber there is no separation between setter and hatcher
Single stage incubator
38
This incubator is a large and size in the mechanism of operation is forced draft in which air is forced by the help of a fan
Mammoth or cabinet incubator
39
It is a large and size that a man can walk in it temperature is set automatically and for ventilation large number of fans are provided what incubator is
Walk in incubator
40
This kind of incubator has a setter and hatcher in a separate chamber
Multistage incubator
41
This incubator work by maintaining a controlled environment with optimal temperature humidity and ventilation to ensure successful embrary development and hatching
Hot air incubator
42
This incubator device used to hatch eggs by maintaining ecosystem and controlled temperature using heated water this incubators are often chosen for their reliability and ability to maintain even heat distribution which is crucial for successful hatching
Hot water incubator
43
This is where eggs are kept in the case of chicken eggs
Setter
44
It is the part of the incubator where eggs are transferred for the final stages of incubation typically the last 3 days for chicken eggs
Hatcher
45
Refers to the percentage of fertile eggs that successfully hatch
Hatchability
46
In candling results, the eggs appears clear
Infertile eggs
47
In canling result, the egg has a blood green is seen around the yolk or possible a dark spot depending on when the embryo stop growing
Dead embryo
48
In candling result the egg will appear to have black spot which has the embryo grows and incubation continues until light will only pass through the air cell end of the egg
Fertile egg
49
What is the formula for hatchability
Hatchability is equal to number of hatch eggs divided by number of fertile egg set multiply to 100
50
It is defined as percentage of eggs those have been fertilized
Fertility
51
What is the formula for fertility
Fertility is equal to number of fertile eggs divided by number of total eggs set multiply to 100
52
What are the factors affecting fertility and machiability
Male to female ratio Rate to lay Age of males Laying pattern Day length Lightning Weather Nutrition Genetic factors Egg handling storage Incubation conditions
53
What day of embryonic stage does yolk is like ball shaped and clear center in a white ring or donut like form

22 hours
58
Appearance of vertebral column are visible
20 hours
59
This is the beginning of formation of nervous system
21 hours
60
What day is this embryonic stage that has elongated embryo, primitive strict visible, embryo surrounded by light yellow ring of subembryonic fluid or SEF
Day 1
61
What day is this if faint blood island is visible and primitive blood cells in blood islands head and tail folds of amnion visible heart is S shaped
Day 2
62
In what hour of day to is the beginning of the formation of the heart
25 hours
63
In what hours of the day to is the hearts begins to beat
42 hours
64
What time of the day to is the beginning of the formation of ear
35 hours
65
What day is is this, head turned left allantois now distinct, first passive movements, embryo started to turn on left side, area vasculosa prominent, sinus terminalis clear, vitelline membrane more than 50% over yolk
Day 3
66
This is the beginning of formation of wings
64 hours
67
Beginning of formation of legs
62 hours
68
Beginning of formation of nose
60 hours
69
Beginning of formation of tongue
Day 4
70
Beginning of formation of permanent organs and differentiation of sex aortic structure begins forming
Day 5
