How To Control The Hatching Temperature Of Breeding Eggs?

How to control the hatching temperature of breeding eggs?

In the past, chickens were used to hatch hens for breeding eggs, but later they could be artificially hatched. Later, they were automatically hatched by computer intelligent control. Either way, temperature is the core condition for successful hatching of hatching eggs. So how to control the hatching temperature of breeding eggs?

In the early stage of incubation, the embryo spraying metabolism is in the primary stage and lacks the ability to regulate, so a higher temperature is required. During the middle period of incubation, the embryo’s material metabolism is gradually strengthened, and the body’s temperature regulation ability is gradually strengthened. At this time, the temperature should be kept stable. The embryo has the ability to regulate body temperature during the later period of incubation and before the shell is released. In addition, it has a strong metabolism and generates a lot of body heat. At this time, the incubation temperature should be slightly lower to facilitate heat dissipation. Therefore, the incubation period should follow the principles of high before, medium and low. When the incubation temperature is high, the embryo develops quickly, and the chicks come out of the shell early; when the temperature is low, the embryo grows and develops slowly, and the hatching time is delayed and delayed.

According to the experiment, the hatching rate is 21 days after hatching at 37.8℃. The hatching rate is highest at 38.5℃. The hatching rate is only 20 days at 38.5℃. The hatching rate is only 19 days at 39.5℃, and the chicks are light-weight and low. And most embryos die in the process of incubation in the shell.

According to the temperature characteristics of the embryo, the human incubation method and the incubation method should be applied to the correct temperature. For example, the batch hatching of the tunnel incubator adopts the constant temperature incubation method, the temperature of the incubator is controlled at 37.8℃, and the temperature of the hatcher is 37.O~37.5℃. Incubation of the whole batch of box-type incubator, using the variable temperature incubation method, the incubation temperature in 1 to 3 days is 38.0 ℃, 4 to 12 days is 37.8 ℃, 13 to 18 days is 37.6 ℃, 19 to 21 days is 37.0 ℃, incubation room Room temperature is controlled at 22~26℃. The temperature mentioned here refers to the air temperature, but the incubator of the incubator where the author is located has the function of measuring the temperature of the eggshell, so the embryo temperature is set at 37.8°C, and the air temperature inside the incubator is set by monitoring the temperature of the eggshell In order to ensure a good temperature environment for embryo development.
