The necessity of ventilation in livestock and poultry houses

To achieve the best production performance of live poultry, 5 key elements are needed.

1) maintain a good hygienic level and a comfortable environment

2) sufficient feed and good quality feed

3) good water quality

4) sufficient oxygen

5) proper and stable temperature

Temperature is particularly important, which is directly related to the comfortable environment of live poultry and the conversion rate of feed (meat to material ratio). In a chicken house, for example, in a comfortable environment, the energy of 60%-70% is converted into output, and 30%-40% is used to maintain life; but in a bad environment, the energy of the 30%-40% is converted to output, and 60%-70% is used to maintain life. It can be seen that environmental temperature and humidity have great influence on live poultry.

And ventilation can bring the following benefits:

1) providing oxygen to animals

2) to provide animals with body sense of wind speed (at the height of animals).

3) elimination of harmful gases, such as carbon dioxide, ammonia, etc.

Ventilation and cooling system of modern houses commonly used negative pressure fan and a wet curtain to achieve the purpose.
