Embodiment 1

[0019] Example 1: Hypoxic incubation experiment

[0020] 1) Incubate 176 Tibetan chicken breeding eggs and 176 Bailaihang breeding eggs according to the normal hatching procedures. The incubation conditions are as follows: set oxygen concentration range of 12.8%-13.2%, carbon dioxide concentration of 5%, temperature of 37.8-38.0 ℃, humidity of 60-65%, turn eggs automatically every two hours, turn on hypoxia simulation control The system reduces the oxygen concentration in the box to 13% within 10 minutes. The incubation lasted 21 days. Try to avoid opening the door of the incubator, observe and carefully record the changes in oxygen concentration, carbon dioxide concentration, temperature and humidity during the incubation period;

[0021] 2) At the beginning of the 22nd day of incubation, turn off the temperature and humidity control system and the simulated hypoxia control system, check and record the number of Tibetan chickens and Bailaihang that hatch. For eggs that have not...

Embodiment 2

[0022] Example 2: Normal oxygen incubation experiment

[0023] 1) 176 white Laihang chicken breeding eggs and Tibetan chicken breeding eggs were selected and hatched according to the normal level. Specifically, the incubation conditions are as follows: carbon dioxide concentration is 5%, temperature is 37.8-38.0°C, humidity is 60-65%, the eggs are turned automatically every two hours, and the incubation time is 21 days. Try to minimize the number of opening the door. Observe and record the changes of the parameters of each system of the incubator during the incubation period, including oxygen concentration, carbon dioxide concentration, temperature, humidity, etc.;

[0024] 2) At the beginning of the 22nd day of incubation, turn off the temperature and humidity control system and the simulated hypoxia control system, check and record the number of Tibetan chickens and Bailaihang that hatch. For eggs that have not hatched, open the eggshells and dissection to determine whether they...

Abstract

The invention relates to the technical field of agriculture and agricultural engineering, in particular to a high altitude hypoxia simulating hatching device. The device comprises a hatching box and also comprises an oxygen control system, a carbon dioxide control system, a temperature control system, a humidity control system and an egg turning control system, wherein the oxygen control system comprises an oxygen concentration sensor, a real-time oxygen monitor and a controller I, and the oxygen concentration sensor monitors oxygen concentration in a hatching box body in real time in a diffusion sampling manner in the electrochemical principle. The hypoxia hatching success rate of Tibetan chickens is 75.57% while the hypoxia hatching success rate of white leghorns is only 38.07%, the normoxia hatching success rate of chicken embryos is 98.9%, the hatching effect is completely identical with that of a common hatching box, which indicates that the transformation method which is simple to operate and low in cost can be used for simulating the chicken embryo hatching process under the high altitude hypoxia condition and can meet the requirement of normoxia hatching, one device has multiple purposes, and the transformed hatching box belongs to modular operation and is easy to maintain.

Description

Technical field [0001] The invention relates to the technical field of agriculture and agricultural engineering, in particular to a plateau hypoxia simulated incubation device. Background technique [0002] High altitude hypoxia simulation is a conventional method to study the physiological, biochemical, pathological, and drug effects and mechanisms of humans, animals, and cells. In recent years, there have been many domestic and foreign research reports on the establishment of hypoxic animal models in hypoxic simulation environment. Especially in recent years, in order to tap high-altitude low-oxygen environment characteristic resources, specific functional proteins, genes and other macromolecular functional substances, as well as low-oxygen metabolism small molecules, more and more researches on high-altitude hypoxia simulation, hypoxia simulation incubation device More and more widespread attention. [0003] After recent years of development, hypoxia simulation has gradually c...
