Holding Room Temperature With Fan

“Preventive Maintenance”

Preventative Maintenance

• Calibrate machine and room equipment

• Monitor settings

• Check embryo temperatures

• Check moisture loss

• Check pipping

• Check chick temperatures

• Confirm: what you think you have is what you have

“Sanitation”

Sanitation

• Run base line studies

• Use reliable products

• Monitor hatcheries

• Fog rooms

• Fumigate inside of machines

• Keep a good air flow through the hatchery

“Egg Set and Transfer ”

Set Times

Breeder Flock Age

• Up to 28 weeks – add 6 hours

• 29 – 30 weeks – add 3 hours

Egg Storage Time

• 1 to 6 days – normal target

• 7 days – add 1 hour

• 8 days – add 2 hours

• 9 days – add 3 hours

• 10 or more days – add 4 hours

TARGET = 504 HOURS

Adjust for breeder flock age and egg storage time

Set and Transfer

• Know your incubation time

• Set consistently (same time every day with exceptions)

• Transfer consistently (same time every day)

• Keep flock age consistent or segregate

Skipped Set Profile(Multistage)

• Temperature needs to be managed for skipped sets

• 14-day rule applies (Embryonic Age)

• Extra incubation time is needed for the 2 sets following a skip

“Embryodiagnosis”

Candle And Residue Breakouts

• Candle eggs ( 10 days to transfer) or residue ( at hatch )

• Look for day embryonic death occurred

• Check flock and machine again

• Check same flock in a different machine

• Check different flock in same machine

• Look for mold

• Look for patterns

• Use hatch of fertile%

Embryo Size

Day 3

• Heart beats

• Blood vessels very visible

Embryonic Development

Day 18

• Growth of embryo nearly complete

• Yolk sac is still on outside of embryo

• Head is under the right wing

Embryonic Development

Day 19

• Yolk sac draws into body cavity

• Amniotic fluid gone

• Embryo occupies most of space with

in egg(not in the air cell)

Embryonic Development

Day 20

• Yolk sac drawn completely into body

• Embryo becomes a chick(breathing in air cell)

• Internal & external pip

Embryonic development

“Chick Assessment”

Pre-Pull

• Hatch Window, Hatch Spread

• 30 hours or less (hatch starts)

• 23 hours- 30%

• 12 hours- 70 to 80%

• Check Chick Temperatures before pull

40℃

40.9℃

• Lower Temperature in hatcher• Timing is important (step down before chick overheats)

• Take temperatures at pre-pull and at pull times

Remember!Step programs are designed to keep chicks from overheating

Not to cool down
