1. Care and Storage of
Hatching Eggs - Before
incubation

2. Why?
good quality eggs
Quality chicks

3. • Good quality egg production
1. Collection
2. Cleaning
3. Fumigation
4. Grading
5. Storing
6. Incubation

4. 1. Collection of eggs
• From healthy well managed breeding
stock
– No vitamin deficiencies
– No mineral deficiencies
High hatchability

5. 2. Cleaning of eggs
• Layer pen –
– Clean
– Litter- renew frequently
• Caged birds
– Remove excreta tray frequently
– Angled bottom – eggs roll outside

6. • Egg shell – avoid contamination of
eggs
– High velocity air
– Brushes
– Sand paper
– Wet clothes
•Do not use water ??
•If essential ??

7. 3. Fumigation
• Disinfectant fume – 20 min
• Proper gas concentration
• Ventilate properly after fumigation
•To fill the air sac with normal fresh air

8. 4. Collect eggs
• 3 – 5 times per day
• At least 2 time
• If Environmental temperature is high –
collect more frequently
Ensure proper cool down
avoid undue effect on the
embryo

9. 5. Handling
• Vigorous shaking - Bad
• Truck inside Temperature – 16 ‘C
• High rotating – Bad
• Non-stop Journey

10. 6. Grading
• According to the weight
Small
Medium 55- 60 g
Large
Jumbo

11. 7. Storing of eggs
• Have to consider
- Duration
- Temperature
- RH
- Orientation and positioning
- Turning

12. 1. Duration –
– Less than 7 days
– If not - Reduce hatchability
Increase Incubation time
2. Temperature -
– Two types - whole storage 20-21 ‘C
Pre Warming

13. 1. Relative Humidity - 75-85 %
– High RH – High MO growth
– Low RH - High evaporation
- weight loss

14. 1. Orientation & Positioning
– Broad side – upward ??
- Air cell
2. Turning – At least once -a- day
– If not ???

15. 8. Pre - warming
• Bringing back eggs from
Storage Temperature
Room Temperature
• Pre-warming Temperature 23’C - !8 hr
