In the process of visiting the market, farmers often heard this sigh: After raising chickens for more than 10 years, they will not be raised now. They are usually better. The incidence of chicken diseases in autumn and winter seasons has risen. The incidence of respiratory diseases has risen. As a result, the egg production rate has also declined, and the use of a large number of drugs has not been effective. Veterinary staff are also confused when they are undergoing clinical treatment. It has been nearly 20 years since the chicken disease was seen. Now that the disease is getting harder and harder to cure, it is impossible to solve the production problems.
Analysis of the Reasons for Chicken Difficulty and Intractable Diseases (1) Abnormal climate. In recent years, the weather in the autumn has been dry and the snow has been reduced in winter. As a result, bacteria and viruses in the environment are multiplying and accumulating, which makes the living environment of the chicken worse and the threat of the disease increase. (2) Breeders, feeds, vaccines, veterinary drugs are unqualified or use is not standardized. Mainly in the non-standard chicken breeding, such as not introduced from the regular chicken base, feeding the feed can not meet the nutritional needs of chickens. (3) The complexity of the disease. At present, the clinical manifestations of chickens mainly show that the old diseases have not been re-introduced into new diseases, and the diseases that currently occur are characterized by typical atypical diseases and increased mixed infections. (4) The level of clinical veterinary treatment is low. (5) Breeders have poor scientific management knowledge, such as regular disinfection, immunization, and feeding of baits.
Solution (1) To raise the threshold of culture, especially for the personnel engaged in aquaculture, it is necessary to have a certain understanding of chicken immunity vaccines and prevention of common diseases. (2) The disease prevention should be placed at the top of the farm, and the qualified chicken house should be built. The chicken should be provided with suitable ambient temperature, humidity, fresh air, clean drinking water, etc. during the breeding process, and be supplied according to different periods of chicken growth. The corresponding feed to meet its growth, try to avoid or reduce the stress caused by various external environments. (3) To establish a scientific concept of disease prevention that combines weight conservation with prevention, prevention with emphasis on treatment, and prevention and control, and establish a reasonable immunization program based on the occurrence of local diseases. (4) Farmers should face up to the status quo and actively take countermeasures. Regularly add a variety of vitamins and mold-removing agents to the feed to make up for the nutritional deficiencies of the feed and to prevent losses from moldy feed. (5) At the same time calling for industry self-regulation, it also needs government departments to increase supervision and law enforcement, reduce the circulation rate of counterfeit feed and veterinary drugs in the market, and purify the veterinary environment. (6) The clinical veterinary practitioners should strengthen their learning, improve the level of clinical diagnosis and treatment, and provide a solid backing force for the majority of farms.
