Classify Work Activities

1.        Cool Room Selection

1 .1 Temperature & Humidity

Avoid all direct blast of air on exposed eggs, we are keep the velocity of the re-circulation to a minimum, this is necessary to prevent dehydration of the eggs. If eggs are hold longer than 7 days, lower temperature are recommended.

Optimum Temperature (dry Bulb): 64-68⁰F – 18-20⁰C

Relative Humidity (%RH): 75-80%

 Are recording condition that at every hours.

1 .2 Protect tools

The lower temperatures in eggs storage the BohMing Company have given protect tools to guard against human dehydration and low risk accident.

The occupier duties in the eggs storage is stacking up of hatching eggs, protect tools on used is a Jacket and a pair of Boot.

1 .3 Disinfectant

Disinfectant use for prevent breeding of the Germ or Microbe

The method of disinfection application is critical. Always follow manufacturer’s recommendations. This ensures efficacy and safety during use. Many Hatcheries are using foaming techniques to increase the exposure time. Not all disinfectants have been formulated to be used with a foamer. The effectiveness of a sanitizer and disinfectant is influenced by the compatibility of the cleaner used with it. Standard operating procedure for bactericidal mixing, administration, and equipment sanitation must be instituted to prevent contamination of the human and environment.

1 .4 Cleaning

After making of stack up hatching eggs, must doing to clean up in eggs storage using the Disinfectant.

2.        Incubation

              2 .0 Definition



• Multi-stage incubation is where the machines are operated continuously, with eggs being set and transferred in the machine once or twice a week. Multi-stage incubation uses the heat generated by the eggs at the end of incubation to warm the eggs at the start of incubation.

• The alternative system is single-stage incubationwhere all the eggs within the incubator are at the same stage of development.

• The major advantages of multi-stage incubation are:

􀂾Lower operating costs due to heat output from older eggs in the incubator being used to warm the younger eggs.

􀂾Simplicity of operation.



2 .1 Procedure

 Cleaning and Maintenance

• Because multi-stage incubators operate continuously, it is difficult to properly clean, disinfect and carry out routine maintenance within the machines. For this reason it is important to programme a time when the multi-stage machines can be completely emptied of eggs.

• If a high incident of contaminated (exploding) eggs occurs it is good practice not to refill the machine until it is empty, to allow through cleaning and disinfection

Temperature

• The exact temperature programme used will depend on the temperature control characteristics of multi-stage machine, but the objective should be to maintain egg temperature within the guidelines given in the Incubation Temperature Advice Sheetb.

• Typically multi-stage incubators will be operating at 37.4 – 37.5ºC (99.3 – 99.5ºF). However, the tunnel type of incubator will normally operate at cooler temperatures, typically 37.0 – 37.1ºC (98.5 – 98.8ºF).

• If eggs are being set into an empty multi-stage incubator (e.g. after cleaning and maintenance) and there are no end of incubation eggs present, then better results can be obtained if a higher temperature is used. The objective is to compensate for the lack of hot eggs in the setter. As a guide:

􀂾Day 1 –3 after first set: +0.4ºC (0.7ºF)

􀂾Day 2 – 6 after first set: +0.2ºC (0.4ºF)

􀂾Day 7 – 9 after first set: +0.1ºC (0.2ºF)

􀂾Day 10 onwards – normal multi-stage temperature.



Humidity

• The basic requirements for incubator humidity are given in the Measuring Egg Water Loss Advice Sheetc.



Ventilation

• Ventilation is necessary to supply oxygen (O2) to the developing embryo and to remove carbon dioxide (CO2). The basic requirements for ventilation are give in the Incubator Ventilation Advice Sheetd.

• In multi-stage machines the ventilation should be sufficient to keep the CO2 level below 0.3%. Do not over ventilate as this will result in problems of temperature and humidity control.

• Where air ventilation is the only method of cooling the incubator, then the level of ventilation must be determined by the machine temperature control system.



Turning

• Eggs should be turned hourly for at least the first 18 days of incubation.

• After day 18 the decision of whether to turn or not will depend on the impact of turning on airflow through the eggs and egg temperature and the machine design. In some machines (e.g. tunnel machines) it is possible to stop turning only eggs after day 18 of incubation and improve the airflow through the eggs. In some cases this has been found beneficial to hatch.

Safety Tools during Hatching

A process hatching day whereas many of quill will make risk for human, so whenever hatching day , take a safety first for body must do use the protect tool as safe as possible, kind of tool is ; a mask, overall, and boot.

3.        FUMIGATION

3 .1 Reason to make fumigation process

A transportation process with a high impact in technical result occurs directly after lay, in the laying nest. At the moment of lay, an egg is wet, warm and the shell is more or less fragile. After lay, the egg dries, cools down and the shell gets more rigid. Under influence of the cooling process, the egg content shrinks and a vacuum is formed, forcing an air stream into the egg. When microorganisms are present at the surface of the egg at this time, the risk of contamination of the eggs is obvious. Bacterial contamination has a detrimental effect on hatchability and chick quality. For this reason, eggs storage and Incubator must be kept as clean as possible.

3 .2 Procedure

Fumigation process must be looking the safety and healthy procedure. Two chemicals name Potassium permanganete and formalin to be mixing with radio 1:2  on the container are fire-prevention, and save gas formaldehyde around 20 minutes then throw in the under drain.

3 .3 Protect Tools

To prevent human risk during fumigation process, must be use the protect tool.

Kind of tools:

-goggles

-hand glove

-mask

-overall

-boot

-a warn sign box.

       4. Cleaning

                The Clean hatchery is very important to get surely human and Day Old chick (DOC) healthy. There are some kind of clean up the hatchery area and human safety protection during do things better.

-          Made a clean sweep the floor and hatchery upper deck

-          Swab or mop the floor with water and disinfectant on efficiently.

-          Use the boot, mask, and hand glove during cleaning.

-          Make it that every day.



5.        Vaccination



A process vaccination surely made when on hatching days. A vaccination process for Injection the Day old chick (DOC) whereas the kind of vaccine is Chick Newcastle Oil, IB (Infectious Bronchitis), and ND for prevent the DOC from zoological Infection.
