The main reason for the failure of native chicken brooding technology

70% of the dead chickens occur during the rearing period. The main reason is that the heat preservation of the brooding room fails, and when entering the chick, the room temperature is only 28 to 29 degrees; the temperature of some rearing rooms is sometimes high and sometimes low, resulting in the decline of disease resistance of chickens and affecting the growth and development of chickens. In some feeds, antibiotics and anti-coccidiosis drugs were blindly added for a long time, which not only led to an increase in cost, but also caused drug resistance of bacteria and parasites.
