Fertile Egg: egg belong to matting hen & by 21 days incubation process, it be hatch to d.o.c

Fertile Egg: blastula egg, it means when ova position the egg in blastoderm stage.

Fertile Egg: egg belong to matting hen with cockerel around 30 hours before (fertility Max : 2-6 days after matting), spermatozoa be able to life in oviduct up to 11-14 days 6-10 days after matting, the eggs still fertile

Infertile Egg: consumption egg, egg belong to unmating hen.

FertilityHatchabilityMortality during hatchery processCandling : observation of egg on 6-7 days and 13-14 days to observe the embryo conditionEgg Index: length/wide X 100%

HATCHERING PROCESS: * NATURAL & ARTIFICIAL

Hatchering Process : 1. Settering 2. Hatchering

Successfull hatchering proccess depend on: - Temperature - Humidity - Sanitation - Ventilation - Controlling

Hatchery Process1. Collecting eggs

* Selection of eggs - Fumigation : to protect invasion of m.o. - Fumigation material : Formalin 40 %,

Potassium Permanganat ( per 100 cubic : 35 cc formalin & 17,5 gr KMnO4)

Hatchery Process2. Holding Room

1. Collecting eggs - selection of eggs - Fumigation : to protect invasion of m.o. - Fumigation material : Formalin 40 %,

Potassium Permanganat ( per 100 cubic : 35 cc formalin & 17,5 gr KMnO4)

Hatchery Process3. Pre Heat

Adaptation Room: to prevent embryo from shock conditionApproximately 6 hrs in room temperature

Hatchery Process4. Setter:

Duration length : 18 days - Temperature 97° – 99° F - Take parallel places with 45° angle - humidity: 86 % - low humidity (82-85%) : crawl feather - high humidity(87-88%) : difficulty to hatch, because of linkage mucous - Turning egg : automatically, every 1 hrs, to keep embryo develop completely. - Provide air fan with rating: 1425 -1450 rpm (to distribute the warm air

Hatchery Process5. Transfer

Moving from setter stage to hatchery incubatorCandling of egg with TL 40 Watt lampInfertile egg (clear chick), take out from incubator When transfer of fertile eggs, hatchery room must be fumigated with KMnO4 (triple doses

Hatchery Process6. Hatchering

3 days (days 19th-21th hari)Fumigation every day with double dosesIncreasing humidity of hatchery room by 0,2° FColoring (Blower) : by formalin 200cc and add some water 400° cc brawniest on d.o. and it keep up to 5-7 days

Hatchery Process7. Pool Chick

DOC (Day Old Chick) do to: - sexing - De beaking - Marek Vaccination (layer) sub cutanaeus around cervical area - Selection : take out abnormally form of beak, blindness, smooth & smaller wing, crawl feather, botak, un symmetric legs, dried leg, omphalitis, wet feather) - The good quality of d.o.c. were placed in cartoon then ready for market.
