The cause of the loss of the embryo inside the egg
The eggs are clear in the light microscope, inside the broken eggs there is a white spot without blood and non-fertile.
reasons:
1- Immature male
2- Male with abnormal sperm
3- Low number of males
4- Bad weather conditions
5- Old herd
6- The disease of the respective mother hen flock
7- Nutritional deficiencies
8- Movement problems of heavy breed males
9- Use of special drugs and chemicals
10- Parasites
11-Insufficient bed
12-Insufficient light
13- Reduction of mating frequency
which is generally seen in many of the mentioned situations.
2- The eggs are grown in the transparent optic disc inside the broken eggs and the blastoderm of the embryo is observed without blood and fertile.
reasons:
1- Long storage of eggs
2- Unsuitable temperature and humidity conditions of the storage place
3- Improper smoking
4- Thermal shocks and egg damage related to these shocks during transportation.
5- Respiration inhibition of eggs
6- High temperature at the beginning of incubation
7- Very young – very old herds
8- Diseases of the mother herd
9- Medicines
10- Unordered collection of eggs
3- Eggs in the clear optics inside broken eggs of blood ring or small embryos that died before three days old shows:
reasons:
1- Storing eggs for a long time under inappropriate temperature conditions
2- Improper smoking
3- High temperature in the early stages of incubation
4-Low temperature in the early stages of incubation
5- Damage to eggs during transportation
6- Diseases of the mother herd
7- The old herd
8-Events in fetal growth and development
9-Severe nutritional deficiencies such as biotin – vitamin A – vitamin E
10- Medicines
11- Pollution
12-Insufficient growth and development
4- Observing a dead embryo on day 3-6 in incubation
reasons:
1- Items mentioned in number 3
2-lack of ventilation – increase of co2
3- Inappropriate rotation of more than one or less than six hours.
5- Observing a dead embryo at 7-17 days in incubation
Embryos have full beak-nails.
reasons:
1- Temperature – humidity – improper ventilation and circulation
2- Pollution
3- Nutrient deficiencies such as biotin, riboflavin, pyridoxine, etc.
4- Lethal genes
6- Observing a dead embryo in 18 days of incubation
reasons:
1- Temperature – humidity – improper circulation and ventilation in the incubator.
2- Contamination, especially caused by molds and fungi.
3-Smoking too hard or too long.
4- Overcooling of eggs during transportation or prolongation of transportation time
5- Breaking the shells before setting – incubation time – transfer time.
6- Nutritional deficiencies.
7- Improper positioning of the fetus.
8- Fetal growth and development events (failure to convert breathing from the yolk sac to pulmonary breathing and fetal blood circulation)
9- Heredity – lethal genes and chromosomal abnormalities.
10- twins (dose category)
11-Hacher has survived for a long time.
12- Low quality of shells.
13- Illness in mother herds.
Troubleshooting – Specific problems
Specific problems
A) Sign: uncapped eggs: including whole embryo – large yolk sac
reasons:
1- Insufficient rotation
2- Very high humidity in the setter.
3- Very low temperature in the setter.
4- Very high temperature in Hatcher.
5- Eggs cooling during transfer.
6- Insufficient ventilation.
7- Diseases of the mother herd.
8- Nutritional deficiencies.
b) The eggs are pricked, the whole embryo inside the shell is dead.
reasons:
1) Humidity and low temperature and long duration in Hatcher.
2) Low humidity during hatching
3) High temperature during hatching.
4) Poor ventilation
5) Insufficient circulation in the first 12 days
6) Damage during transportation
c) Eggs incompletely pecked dead or alive embryos
reasons:
1- The above items in paragraph b
2- Excessive smoking during the hatch
3- Picking the eggs upside down
Goodbye mycoplasma!
After many efforts and follow-ups, the Mycoplasma vaccine (the most acute uncontrollable disease of turkey) was finally imported from Spain!
One of the advantages of this vaccine is the isolation of up to two generations from the produced chickens of the mother flock
