Q: Broilers were 25 days old. There were large numbers of burps, lack of energy, and a serious decline in feed intake. E. coli and coccidial infections were found during dissection. Air bags were poor and the respiratory tract was not good. How to do? A: This situation is mainly related to the poor feeding and management in the previous period. During the early feeding process, it is necessary to pay attention to the fresh air in the house, the stocking density should not be too large, and the manure should be diligently cleaned. Otherwise, the chickens will suffer from repeated infections with mycoplasma. Or E. coli-type air-saccharitis, which in turn forms the pericardial encephalitis of E. coli. In addition, the failure to achieve timely and effective treatment of mycoplasma and E. coli infections in the early stages of chickens is also responsible for the current situation. . Every day, chickens can use 20 mg of tilmicosin, 50 mg of doxycycline and 20 mg of florfenicol per day for five consecutive days, which can greatly reduce the mortality of the flock. However, serious chickens with liver-protective and air-bag cheese-like substances have already been formed in the flock and they can be picked out and treated as harmless.
