Changing feathers is the latest season for pigeons to change feathers. Every year is usually the season of pigeon molting, and the molting time of high-yield bell pigeons is short. As the name implies, shortening the molting cycle can improve the spawning rate. It is suggested that hemp be added to the feed to shorten the time of changing feathers. Bell pigeons stopped production because of Newcastle disease, pigeon pox, candidiasis, chronic respiratory diseases and other infectious diseases, reproductive tract inflammation, chronic enteritis and other diseases. It is easy to cause pigeons to stop production. When pigeons suffer from paratyphoid fever, pigeon tuberculosis and diarrhea during childbirth, the bell pigeon will completely stop laying eggs. Therefore, vaccination, drug prevention, cleaning and disinfection should be done well in production.
Bell pigeons that produce egg fatigue, such as sarcoma pigeons, hatch three eggs in a row and feed three pigeons, which is easy to cause excessive fatigue. Fatigue often leads to production in the second year of production. In order to prevent pigeon fatigue, combined with changing feathers, it is best to have a rest time of one to two months every winter. During this period, they are all raised in groups, and vaccination during production may stop production. In addition, some drugs such as chloramphenicol and sulfanilamide may be discontinued, so the use of turtledove should be banned.
The laying rate of meat pigeons is closely related to the quality of breeding pigeons. Pigeon farms should screen and eliminate updated pigeons in time. Generally, the laying time is long and the winter rest period is short. 8 breeding pigeons with more than Yanshan eggs are regarded as mountain pigeons, and production should be stopped appropriately. Eliminate the old, weak, sick, disabled and other low-yield pigeons with less egg production and long vacation time, timely select high-yield breeding pigeons to supplement the shortage, update the breeding pigeon population, and improve the overall egg production rate. Any disease will affect the oviposition rate of pigeons. Especially in the case of severe diseases such as paratyphoid fever and tuberculosis, pigeons may stop production completely. Therefore, pigeon farms should strengthen the health management of pigeons, provide comfortable living space for pigeons, provide clean drinking water and high-quality diet, and reduce the harm of pigeons to eating and drinking well, the environment is good and pathogenic microorganisms.
