Why the old dead chicken?

Before getting ready to enter the chicks, the henhouse was not thoroughly disinfected, the heat preservation equipment was lacking, and the chicks did not drink and eat as soon as possible after entering the house, failing to raise chicks carefully and cultivate strong seedlings. In winter, only pay attention to the heat preservation of chicks, while ignoring the heat preservation of medium and big chickens, resulting in a large number of chicken deaths.

Lack of long-term planning, the chicken house is simple, the basic facilities and technical conditions are poor, and it is greatly affected by the external environment. For example, the heating of coal stove is often used during the breeding period, and the temperature can not be adjusted automatically, and the temperature will rise and fall, which can easily lead to the disease and death of chickens.

Do not understand @ # @ 230 chicken farmers only pay attention to efficiency rather than science. Therefore, when the price is good, more seedlings can be imported, and two or three groups of chickens of different breeds and different ages are raised in the same henhouse with high density and poor ventilation, so that it is impossible to complete entry and exit and strict disinfection at all, so that pathogens are passed on from generation to generation, virulence is enhanced, and all diseases are reborn. It increases the difficulty of prevention, diagnosis and treatment.

Unreasonable drug use exists in many chicken farmers who use drugs indiscriminately or not. Medication is not timely, will delay the disease; overdose, easy to cause poisoning; conservative use of drugs, resulting in drug resistance of pathogens and so on. In addition, there are so many fake and substandard drugs on the market that it is difficult for chicken farmers to distinguish between true and false, which is also the reason for the increase in the cost of dead chickens and raising chickens.

The management of extensive chicken sheds has poor hygiene and neglects disinfection, resulting in serious colibacillosis, mildew disease and so on. When the chickens were treated with drugs, the morbidity and mortality decreased significantly, but relapsed 2-3 days after drug withdrawal, which was caused by serious environmental pollution. Some sick and weak chickens were not quarantined in time, dead chickens and chicken droppings did not seriously achieve harmless treatment, rodent and pest control did not achieve institutionalization, resulting in the spread of pathogens, repeated infection, and increased the difficulty of treatment.
