Skills of raising chickens to increase efficiency in winter and spring

Winter and spring alternate, the weather is cold, green feed shortage, chicken at this time to obtain high benefits, must do the following.

Keep warm: low temperature has a very obvious effect on laying hens, so it is necessary to increase the feeding density, close the doors and windows, add straw curtains, stove heating and other ways to keep warm, so that the chicken house temperature is maintained at a minimum of 3-5℃. Ventilation: Due to the low temperature, the doors and windows of the chicken house are closed tightly, and the ventilation volume is reduced. The exhaust gas emitted by the chicken and the harmful gases such as ammonia, carbon dioxide and hydrogen sulfide generated by chicken manure fermentation will accumulate in the chicken house, which is easy to induce diseases such as respiratory tract of the chicken. To deal with the relationship between ventilation and warmth of chicken houses, timely removal of feces and debris. When the weather is better, windows should be opened for ventilation to make the air fresh and oxygen sufficient, so as to prevent problems before they occur. But be careful not to let the cold wind blow straight, in case the chicken catches a cold. Disinfection: The temperature in winter and spring is low, the activity frequency of bacteria decreases, but the resistance of chickens is generally weakened. If disinfection is neglected, it is easy to cause disease outbreak and epidemic. Therefore, disinfection of chicken houses must be done well. Supplementary light: winter and spring season day short night long, laying hens often due to insufficient light caused by egg production rate decline. Artificial supplementary illumination can be used. The total time of illumination should not be less than 14 hours per day, but it should not exceed 17 hours. If the illumination time is too long, it will cause physiological disorders of chickens.
