How to increase the efficiency of raising chickens in winter and spring

At the turn of winter and spring, the weather is cold and green feed is scarce. if chickens want to get high benefit, they must do the following.

The effect of keeping warm and low temperature on laying hens is very obvious, and the lowest temperature of henhouse can be kept at 3-5 ℃ by properly increasing feeding density, closing doors and windows, adding grass curtain, furnace heating and so on. Ventilation due to low temperature, chicken house doors and windows are closed strictly, ventilation is reduced, chicken exhaust gas and ammonia, carbon dioxide, hydrogen sulfide and other harmful gases produced by chicken manure fermentation will accumulate in the chicken house, which is easy to induce respiratory diseases and other diseases. It is necessary to deal with the relationship between ventilation and warmth in the chicken house and remove faeces and sundries in time. When the weather is good, windows should be opened for ventilation so that the air is fresh and oxygen is sufficient to prevent problems before they occur. But be careful not to let the cold wind blow directly to prevent the chicken from catching a cold. The temperature of disinfection in winter and spring is low, and the activity frequency of bacteria decreases, but the resistance of chicken flocks is generally weakened. if disinfection is ignored, it is very easy to lead to disease outbreaks and epidemics, so we must do a good job in disinfection of chicken sheds. During the winter and spring seasons, the days are short and the nights are long, and the laying rate of laying hens often decreases due to lack of light. Can use artificial supplementary light, the total time of light every day should not be less than 14 hours, but not more than 17 hours, light time is too long, will cause chicken physiological function disorder.
