CHINESEThere 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.
