Make turkey hatching special and professional
Turkey hatching begins with the preparation of suitable fertilized eggs. Since turkeys are heavy, the rate of unsuccessful mating in this bird is high, and as a result, the amount of unfertilized eggs in turkey hatching is high. Therefore, it is necessary to use artificial insemination in some heavy breeds of turkey.
The method of storing and transporting spermized turkey eggs has a great effect on increasing the percentage of hatching turkeys. Compliance with these principles is the same for all birds and you can see the necessary conditions for keeping fertilized eggs from here.
The most important factor to get the best result during turkey incubation is providing the right temperature for embryo growth. In addition to humidity, ventilation and air circulation in the turkey incubator are important things that, if not properly controlled, will have adverse and irreparable effects on the performance of turkey incubation and turkey breeding.
Finally, the eggs are not very sensitive to the slight changes of these three factors, but a slight change in the temperature that can be tolerated by the embryo and its unnecessary increase or decrease can have a significant effect on reducing the ability of turkeys to lay eggs.
It should be noted that the best temperature for turkey incubation is the average temperature of 37.5 degrees Celsius. Incubation at a temperature higher than 38 degrees on 18-24 days has resulted in a significant decrease in hatching ability and an increase in embryo losses, and special signs from the point of view of pathology such as inversion and displacement of the embryo, water Eyes will create. Also, keeping the temperature constant at around 5.36 degrees will delay the hatching of the turkey. Temperatures higher than 37.5 degrees Celsius will have far more destructive effects on turkey hatching than temperatures lower than that.
The biggest decrease in turkey hatching rate is observed when high temperature is applied during the second week of incubation, in other words, applying a temperature of 38 degrees when applied for 6 days and in the first, third and fourth week of incubation. It will not affect the result.
In the turkey brooder, change the temperature every week
But in the second week of turkey hatching, applying the same temperature causes a decrease in the amount of chicks harvested. This issue shows the special sensitivity of turkey embryos to high temperatures, especially in the second week of incubation. Therefore, it is better to set the temperature at 38.5 degrees in turkey hatching at the beginning of the harvest and change the temperature to 37.7 degrees on the sixth day, and after the end of the 14th day, change the temperature to 37.5 degrees and until We maintain this temperature on the 25th day.
On the 25th day, to enter the hatch stage, it is necessary to reduce the temperature of the machine to 2.37. The relative humidity should be around 60% in the first 24 days and 70% in the last 4 days. The incubation period in turkey is 28 days. Usually, chicks start pecking and hatching from the 27th day.
