Intelligent integrated monitoring and control scheme for livestock and poultry breeding environment
 
I. brief introduction of intelligent integrated monitoring and control program for livestock and poultry breeding environment
      the scheme mainly introduces the popularization and application of the integrated monitoring system for livestock and poultry breeding in the livestock and poultry breeding industry. The system is mainly composed of upper computer management system, automatic control system, data acquisition system, on-site sensors and other parts.
Comprehensive monitoring can realize animal farms, including indoor temperature, humidity, carbon dioxide concentration, oxygen concentration, light intensity, pressure, and temperature, humidity and harmful gas concentration, illumination automatic or manual control, to provide a comfortable environment for animal farming industry, improve economic efficiency. This project takes the comprehensive monitoring and monitoring of chicken farm as an example.
    there are obvious differences in the north and south, East and West climate in China, caused by temperature, humidity and illumination parameters vary greatly, mainly in the northern cold, to the south of the Yangtze River in summer.
Two. Describe and introduce the function of environmental monitoring system of chicken farm
Chicken breeding and rearing forms the basis and decide, henhouse building should follow the "easy management, easy for lighting, summer, winter cold, for epidemic prevention" principle.
    through the comprehensive control system of temperature and humidity, gas concentration and light intensity automatic / manual adjustment and control, support manual control, create a comfortable and healthy environment for the growth of animal, to achieve better economic benefits.
(a) the henhouse temperature and humidity regulation, to create a comfortable environment, temperature and humidity.
Through indoor and outdoor temperature contrast, in hot summer, when the indoor temperature is higher than the outdoor temperature, start the fan to carry on the air exchange, to indoor cooling; when the indoor humidity is higher than the outdoor humidity and the humidity is big,
Start the fan ventilation and wet in the winter; especially in North China, the need for housing insulation treatment, appropriate to send warm (such as solar energy, electric furnace, boiler heating etc.).
1. temperature factor:  
Temperature is a key factor in the success or failure of a chicken farm. If the temperature is too low, easy to catch chickens caused by diarrhea or respiratory diseases; heating is easy to cause the chick to get together, the impact of feeding and activity, resulting in severe disability, will cause a lot of death. Therefore, the chicken farm must pay attention to temperature control.
Master the chicken characteristics, strict temperature index of chick growth suitable temperature decreased with the increase of age, the 1 day old ~2 days incubation temperature of 35 DEG ~34 DEG, farm temperature of 25 DEG ~24 DEG; 3 days ~7 days incubation temperature of 34 DEG ~31 DEG, farm temperature is 24 DEG ~22 DEG C; second week incubation temperature is 31 DEG ~29 DEG C, farm temperature is 22 DEG ~21 DEG C; third week incubation temperature of 29 DEG ~27 DEG, farm temperature is 21 DEG ~19 DEG C; fourth week incubation temperature of 27 DEG ~25 DEG, farm temperature of 19 DEG ~18 deg. The farm incubator temperature than low, making homes within a certain temperature, you can freely choose the suitable incubation temperature required, is conducive to the growth of chicks; chick growth temperature must be kept stable, not fluctuated, otherwise we can not keep a good feed for chickens.
The temperature is critical for raising chickens
TwoHumidity factor
(1) the method of expressing air humidity and the source of moisture in the chicken house, the humidity of the air, referred to as "air humidity", indicates the moisture content in the air, indicating the degree of moisture in the air. Usually expressed in terms of relative humidity, the percentage of actual water vapor in the air and the amount of saturated water vapor at the same temperature (%). The main source of indoor water vapor is exhaled water vapor, water vapor in homes can be accounted for 75% of the total, especially at high water vapor content Sherwin, chicken by breathing out of many. Followed by air water vapor, this part of water vapor due to the location and weather conditions are different, generally accounted for 10% to 15% of the water vapor in the house. In addition, the evaporation of water from the ground, wall, trough and pad accounts for 10% to 15% of the water vapor in the house. Water vapor in the upper and lower parts of the house more, such as the chicken cage insulation, poor heat, water vapor cold, easy to cold objects in the surface condensed into drops of water fell to the ground.
(2) the influence of air humidity on chicken; the influence of air humidity on chicken is combined with temperature. At proper temperature, air humidity has little influence on the heat regulating function of chicken body, so it has little influence on the production performance. High temperature, the chicken mainly by evaporation heat, the high humidity of the air to make the chicken evaporation, heat blocked, body heat easily accumulate in the body, and even make the body temperature rise, production performance decline.
There are high temperature and low humidity evaporation cooling for chicken. As a result, chickens can tolerate higher temperatures in low humidity environments. When the temperature is low, the chicken body radiates heat mainly through radiation, conduction and convection, and the heat capacity and thermal conductivity of the humid air are higher, so that the heat dissipation of the chicken body is increased. At the same time, the moist air causes the chicken feather humidity to increase, the heat preservation performance drops, loses the heat to increase, causes the chicken to feel more cold, causes the feed consumption to increase, the productivity drops, even frostbite. Chicken can tolerate low temperature and humidity environment, just feed consumption increased.
(3) when the suitable humidity of chicken is suitable, the relative humidity is between 60% and 65%. It is generally considered that 40% ~ 72% is the suitable humidity of chicken. The upper limit temperature of the laying hen decreased with the increase of humidity, the temperature of 28, relative humidity 75%, temperature 31, relative humidity 50% and temperature 33, relative humidity 30%, the production performance of the same performance. That is, relative humidity drops from 75% to 30%, relative to a temperature drop of 5 degrees centigrade. The relative humidity in winter is over 85%, which has bad influence on egg laying. The daily gain of light chicken was and 80% at the temperature of 29 and relative humidity of 40% and 13.8g, respectively. The daily gain of heavy chicken was 30.6g and 29.7g respectively, and the feed conversion rate was also increased by about 2.5%. High temperature and high humidity can promote the breeding of microorganisms, leading to the occurrence of diseases and feed mildew. But the air should not be too dry, especially at high temperatures, drying will affect the mucosal and skin defense capabilities. Relative humidity below 35%, easy to cause respiratory diseases, so that the growth of feathers of chickens, the house dust increased, but also one of the causes of pecking. Therefore, to prevent moisture and excessive drying in the shed is also an important task of management.
So humidity is also an important parameter in the culture environment!
Effect of 3. ammonia concentration on chickens
Effect of ammonia gas on chicken in poultry house and chicken house. As a result of chicken manure produced a large number of ammonia, when the chicken house air ammonia reached 20ppm (equivalent to 15.2mg/m3), lasting more than 6 weeks, can cause lung congestion, edema, chicken chicken egg reduced, decreased appetite, susceptible to illness; such as 50ppm, the number of days after the occurrence of chicken larynx edema, necrotizing bronchitis, pulmonary hemorrhage, respiratory rate decreased, and the emergence of death.
Therefore, the concentration of ammonia in the air of poultry house should be controlled below 20ppm. From this, we can see indoor air pollution of low concentration ammonia pollution on human health hazards.
Explanation: the specific environmental parameters mentioned above are for reference only. The parameters are different according to the type of chicken and the number of chickens. The environmental monitoring parameters are set according to the actual conditions of the field!
