Care Of Hatching Eggs
Care Of Hatching Eggs
The quality of day old chicks depends on the quality of the
hatching eggs which produced the chicks.
- When can you say hatching eggs are of the best quality or how do we judge the quality of hatching eggs?
Hatching Egg Quality
Internal External
Disease free parents. Free from shell contamination
Protective M.A.B Titres Correct shell thickness
Sufficient nut. package Even texture & shape of shell.
High fertility Normal pigmentation.
- Important facts you should keep in mind :
– You are responsible for producing hatching eggs of the
best quality.
– Once an egg is laid, you cannot add anything good to it
– you cannot improve.
– You can either maintain quality or destroy it.
- How to produce and select hatching eggs.
Hatching eggs can be contaminated
-As the egg in being laid.
-In the nest box.
-When laid on floor.
-Bacteria can enter the shell within 2-3 hrs after an egg is laid.
-Bacteria divide into two –every seconds.
- How will you sanitise the nest box material?
- How will you prevent floor eggs
- Selection of Hatching eggs : On what basis?
- Egg size:
– Do not allow egg size to go uncontrolled on the higher side.
– Beware of under size eggs.
What do small eggs indicate?
How do you improve egg size?
– Do not mix eggs of different sizes in the same trays. WHY?
- Shell Quality:
Thin and porous shells can be the result of.
* Viral infections
* High environmental temperatures.
* Respiratory disturbances
* Nutritional imbalance
What are your experiences in handling this problem?
- Internal Quality:
* Keep an eye on the quality of albumen and yolk
regularly.
* Contaminated shells & Undue delay in picking up, selecting and storing in the cool room affect the internal quality.
What is the practice at your farm?
* Are your females and males getting their individual requirement of nutrients.
* How about the body weight and health of your males?
- Correct ways to store hatching eggs:
- What in your cool room temperature and relative humidity?
Dry bulb:
Wet bulb:
Rel. Humidity:
What are the ideal levels?
- Avoid excessive evaporation :
Check evaporative loss of the same eggs during storage by test weighing once in a way.
- Internal quality suffers with period of storage – your practice?
- Fluctuating temperatures are harmful even if within limits?
- Air movement around eggs is not advisable as some behive.
- Store eggs large end up. why?
- Plastic trays are preferred to paper trays. Discuss this.
- Repeat the individuality of Hatching eggs, namely,
* Size
* Age of the parents from which they come.
* Quality of eggs from particular flocks and their response to environment.
- There is a strong co-relation among
Hatchability
Chick quality and the individuality factors mentioned
above.
- Be sensitive to any change anywhere and anytime?
For Practical Discussion:
- Cleaning.
- Disinfection
- Storage
- Transportation
- Your actual practice
- Merits & De-merits of your system?
For Discussion:
- Does biosecurity consist in the practice of liberally using large quantities of disinfectants and also possessing experience equipment?
- What are all the reasons why diseases in general exist, spread, get out of control at time – like epidemics of cholera in some places, as well as persist more in a country like ours than in other places?
- To what extent can we blame the organisms, weather etc for the dangerous situation around on?
- Now try and understand where real Biosecurity starts.
Biosecurity in a way of life like
– Personal hygiene
– Dressing habits & good house keeping.
- Suguna has invested much in providing and cultivating good biosecurity on our farms.
- a) What are the aims?
- b) Have we been successful? To What extent?
- Practical discussion on Biosecurity.
- Set up 2. Actual practice.
- Merits 4. Weaknesses of the biosecurity systems in each of our farms, starting from the gate, as follows.
