          Necessity of ventilation in livestock and poultry houses
          DATE:2017-12-06    HITS:1261

          There 5 elements have effect on raising livestock to achieve the best production performance, as following:

          1 ) Maintain good health level and comfortable environment

          2 ) Adequate feed and good quality feed

          3 ) Good water quality

          4 ) Sufficient oxygen

          5 ) Appropriate and stable temperature

          Among them, temperature is particularly important, directly related to whether the living poultry growth environment is comfort or not and feed conversion rate ( meat ratio ).  Take the chicken house as an example, in a comfortable environment, 60 % - 70 % of the energy into output, 30 % - 40 % for the maintenance of life;  But in bad conditions, 30 % - 40 % of energy is converted to output and 60 % - 70 % is used to sustain life.  Therefore, environmental temperature and humidity have a great influence on livestock.

          Ventilation offers the following benefits:

          1 ) supplying oxygen to livestock

          2 ) providing the livestock with a body wind speed ( at the height of them)

          3 ) removing harmful gases such as carbon dioxide and ammonia

          4 ) removing excess water ( humidity ) from the premises

          In modern poultry houses, exhaust fan and cooling pad system are commonly used for cooling and ventilation.
