How to ventilate chickens in a cage

In the process of cage keeping, poor care can easily lead to diseases and even death in the chicken flock. The growth of the chicks is fast, the metabolism is relatively vigorous, the oxygen required is relatively large, and the carbon dioxide discharged is also large, which seriously affects the health of the chicken flock. Therefore, the ventilation of the chicken house is very important.

Layer cage manufacturers believe that, under the temperature and humidity conditions of the breeding sheds, the decomposition of feces and bedding materials by microorganisms produce a large number of ammonia and hydrogen sulfide and other undesirable gases. Too much accumulation of these gases in the brooder will cause air pollution, which will affect the growth and health of the chicks. If the carbon dioxide content inside raising cheeper is exiguous, the breathing number of chicken increases significantly, when serious, chicken spirit is worn out, appetite drops, growth is slow, constitution drops.

 

Ammonia gas concentration is too high, can cause chicken lung edema, congestion, conjunctival stimulation of the eye caused keratitis and conjunctivitis, and can induce the occurrence of upper respiratory disease. High hydrogen sulfide gas content will also make the chicken feel uncomfortable, reduced appetite and so on. Accordingly, should pay attention to the ventilated take a breath of brood house, eliminate harmful gas in time, maintain the air inside shed is fresh, make the content of ammonia gas inside shed of harmful gas, hydrogen sulfide, carbon dioxide does not exceed 0.05 to rise/metre 3 respectively, 0.01 rise/metre 3 and 3.5 rise/metre 3, after namely person enters brood house, do not have acrid, dazzling feeling. In ventilation at the same time also want to pay attention to the temperature changes in the house, to prevent the gap of wind blowing, so as not to cause chicken cold.

 

Natural ventilation and forced ventilation are the two methods of ventilation. Open chicken coop ventilation can be solved by natural ventilation. Its specific practice is: every noon 12 o 'clock or so opens the window of chaoyang appropriately, should show half to open a state from small to big finally, must not open door window suddenly greatly, do not let cold wind blow chicken directly, the time that opens a window is 0.5-1 hour commonly. In order to prevent house temperature from decreasing, house temperature should be increased from 1-29c before ventilation, and then reduced to the original temperature after ventilation. Layer cage manufacturers recommend that the enclosed chicken coop be forced ventilated by powered mechanical fans. The specific ventilation requirements are: 0.03-0.06 cubic meters per minute in winter and early spring, and 0.12 cubic meters per minute in summer.
