The temperature and humidity environment monitoring system for chicken houses and chickens is based on the accurate measurement of the temperature and humidity in the chicken house. According to the requirements of the temperature and humidity in the chicken house, when the temperature and humidity in the chicken house are too high or too low, the cooling and dehumidification are started in time. Or increase the temperature and humidity to ensure a reasonable temperature and humidity in the house.
The main parameters monitored in the house include temperature and humidity in the house, light intensity, ammonia concentration, H2S concentration, carbon monoxide concentration, carbon dioxide concentration, etc. To do a good job of breeding, we must understand the monitoring and control of the above environmental parameters.
1. Temperature monitoring and control in the house.
温度25℃~24℃； 1 day to 2 day incubator temperature 35 ℃ ~ 34 ℃, chicken house temperature 25 ℃ ~ 24 ℃;
温度24℃~22℃； 3 ~ 7 days incubator temperature is 34 ℃ ~ 31 ℃, chicken house temperature is 24 ℃ ~ 22 ℃;
温度22℃~21℃； In the second week, the temperature of the incubator is 31 ℃ ~ 29 ℃, and the temperature of the chicken house is 22 ℃ ~ 21 ℃;
温度21℃~19℃； In the third week, the temperature of the incubator is 29 ℃ ~ 27 ℃, and the temperature of the chicken house is 21 ℃ ~ 19 ℃;
温度19℃~18℃。 In the fourth week, the temperature of the incubator was 27 ℃ ~ 25 ℃, and the temperature of the chicken house was 19 ℃ ~ 18 ℃.
温度要比孵化器的低，使舍内有一定温差，孵化就可随意选择所需的适宜温度，有利于小鸡的生长；小鸡生长温度必须保持平稳，注意温度不能忽高忽低，否则必将影响小鸡生长。 The temperature of the chicken house is lower than that of the incubator, so that there is a certain temperature difference in the house. You can choose the appropriate temperature for the hatching, which is conducive to the growth of the chicks. The growth temperature of the chicks must be kept stable. Otherwise, it will affect the growth of chicks.
2. Humidity monitoring and control in the chicken house.
At the appropriate temperature, it is generally considered that 40% to 72% is the appropriate humidity for the chicken.
The upper limit temperature of laying hens decreases with increasing humidity. The reference data is as follows:
Temperature 28 ° C, relative humidity 75%
Temperature 31 ℃, relative humidity 50%
Temperature 33 ℃, relative humidity 30%
3.Light intensity monitoring and control
The hen's enthusiasm for laying eggs is affected by the time of light. Under the light, the hen's mood is stable and the number of eggs is increased. Generally, 12 to 14 hours of light per day can promote the movement and eating of chickens, especially can stimulate ovarian development, so that the hen's egg laying period can be prolonged, and the number of off-season eggs can be increased. Light can not only enhance the hen's physique, but also promote the secretion of hen's pituitary gland hormones, so that the hen's egg production is vigorous.
Sun light can encourage chickens to produce vitamin D on their own, and vitamin D helps the utilization and absorption of calcium. Calcium is an important part of egg shells, so the sun can lay eggs normally and avoid soft shell eggs. The second reason is that chickens are Those who eat during the day, stop eating as soon as the light is dim. In order to promote growth, the light should be enhanced.
4. Monitoring and control of ammonia concentration in the chicken house.
The level of ammonia gas will directly affect the growth and development of animals and their ability to resist viruses. Ammonia can cause rapid growth and metabolism of mucosal cells, which will increase the need for oxygen and energy. At the same time, the detoxification process of ammonia is a highly energy-consuming process, so the energy used by animals for growth and production will be reduced accordingly, which will affect Animal growth performance. Ventilation and timely removal of feces can effectively reduce ammonia concentration.
5. Monitoring and control of hydrogen sulfide concentration.
Hydrogen sulfide is generated by the decomposition of flowing organic matter. However, the chicken house often suffers from broken eggs and poor ventilation, which results in an increase in the hydrogen sulfide content in the house. Due to the large proportion of hydrogen sulfide, it harms the lower chickens seriously. It can cause keratitis, which in severe cases can lead to paralysis of the respiratory center and death. Long-term poisoning with low concentration of hydrogen sulfide can reduce the chicken's body condition, reduce disease resistance, and reduce production performance. Prone to disease. The concentration of hydrogen sulfide in the chicken house is generally not more than 10 mg / L. Ventilation and timely removal of feces can effectively reduce the concentration of hydrogen sulfide gas.
6. Monitoring and control of carbon monoxide concentration.
Carbon monoxide is odorless and non-irritating gas. Generally, no carbon monoxide is generated in the chicken house. It is only possible to produce large amounts of carbon monoxide in cattle when the chicken coop is heated and insulated in winter. Carbon monoxide has a strong toxic effect. Hefei Yihongyuan easily binds to the hemoglobin of the blood towel and is not easy to separate, causing hemoglobin to lose its oxygen-sparing function, causing the body to be hypoxic and poisoned. Carbon monoxide poisoning mostly occurs in the broiler house, because it is colorless and tasteless, and it is difficult to judge based on perception, so it is more threatening to chicks. In severe cases, a large number of chicks can die. The concentration of carbon monoxide in chicken houses generally requires more than 24 ml of wood.
7. Monitoring and control of carbon dioxide concentration.
Carbon dioxide is an odorless irritant gas and is inherently toxic. The carbon dioxide in the chicken house mainly comes from the chicken's breathing. Carbon dioxide poisoning is related to hypoxia. If the carbon dioxide concentration in the chicken house is too high, the oxygen concentration in the chicken house will be too low and the chicken house will be hypoxic, which will cause chronic poisoning, which will reduce the appetite of the chicken and weaken its constitution. The hygienic significance of carbon dioxide is to indicate the degree of air pollution in the house. Carbon dioxide and chronic poisoning mostly occur in the brooding room. When the weather is cold, the brooding room is continuously heated with electric hot plates. At the same time, it is more likely to occur when the doors and windows are tightly closed, the ventilation is not good, and the feeding density is too large.
内的温湿度和气体浓度需要及时的监测与控制，否则会造成养殖的重大损失。 The temperature, humidity and gas concentration in the chicken house need to be monitored and controlled in time, otherwise it will cause significant losses in the breeding. The use of a livestock and poultry breeding environment monitoring system can monitor the temperature and gas concentration values in the chicken house 24 hours. When an abnormality occurs, the monitoring system can not only promptly alarm, but also automatically control the equipment to improve the air environment and ensure the quality of breeding.
