FAILURE HATCHING EGGS


In the process of hatching failure and Possible Cause

Breeding or hatching of ducks using a hatchery | incubator is helping farmers in an attempt to duck seedlings in higher numbers when compared with the natural hatching.

As for some of the factors that are often encountered in the process of hatching breeders using artificial brooders tool, among others, as follows:

1. Infertile eggs

Some of the factors that cause the eggs are infertile or not had spermatozoid:

Comparison of male and female parent does not meet the requirements
Parent male / female is too old
Female parent too fat
Hatching egg shell cleanliness
Eggs stored for too long in the condition that does not fit before input into the incubator
Parent parent stock feed deficient in vitamin A, B, C or E and
Parent stock experiencing pain / stress.
2. Embryos die early

If the embryos die much earlier, possible causes are:

Incubator temperature is too high or too low
Genetic parent stock
Errors in the process of fumigation (fogging)
Errors on playback eggs
Stress / illness on parent stock
3. Many embryos die at hatching machine

When embryos are dying, just before egg shell cracked, then the possible causes are:

Playback eggs that are not true,
Temperature and humidity incubator improper,
Factors generic parent stock,
Laying eggs in the incorrect direction tray, which should be rounded at the top and tapered at the bottom.
Air circulation is not good
4. Many embryos that died after cracking eggshells

When the embryo is dead after a lot of egg shells cracked, then the probable cause is humidity in the hatcher machines (hatching) is too low and the temperature fluctuations in the machine setter.

5. When the final stock hatch too fast

Probably caused by engine temperature setter / hatcher is too high.

6. Final stock late hatch

When the final stock late hatch, probably caused by engine temperature is too low or setters before hatching, the eggs hatching has long kept.

7. Final stock unison not hatch

When the final stock asynchronous hatching, possible causes are:

Spread of heat inside the incubator is uneven
Hatching eggs from parent / parent stock of different ages and
Egg size varied
8. Final stock navel does not close completely

When the final stock navel does not close completely, possible causes are:

Temperature is too high in hatcher machine
Temperatures in machine setters too fluctuating
Errors during fumigation techniques are eggs hacther machine and
Humidity in the hatcher machines are too low.
9. Final stock closed fluid

When the final stock closed fluid, then the possible causes are:

Incubator temperature is too low,
Humidity in the incubator is too high and
Nutrient content is less precise parent stock feed.
10.Final stock is too small

When the final stock is too small, then the possible causes are:

Hatching egg weight is too low
Humidity in the incubator is too low and
Incubator temperature is too high
11.Final weak stock

When the final stock is too weak, then the probable cause is

Temperature is too high in hatcher machine
Humidity is too high in hatcher machine
Nutrient content is less precise parent stock feed
Hatching eggs from stem young parent stock.

Thus several factors that can cause a failure in the process of hatching and possible causes. We hope this article would help the farmers in an effort to obtain seeds or seedlings ducks other birds in order to avoid errors in the process of hatching later.

If there are fellow breeders who have experience in breeding ducks, good tips or ideas and questions about breeding ducks, please share your experiences with “duck intensife”.

Good work!
