A production method of immunocompetence feed for native chickens

The present invention discloses a production method of immunocompetence feed for native chickens. The feed contains unique biological active ingredients and other nutritional ingredients of cordyceps. The production method comprises the following steps: choosing the culture medium after finish of cordyceps culture cycle and completion of harvesting fruiting body (cordyceps culture medium for short), conducting low-temperature vacuum drying and airflow ultrafine grinding on the cordyceps culture medium, mixing the cordyceps culture medium with conventional native chicken feed evenly, putting the mixture into a feed particle machine to make extrusion and granulation, and obtaining the immunocompetence feed. By regulating the immune function of chicken, the feed can improve disease prevention and resistance function of the native chickens, and can avoid the problems of ecological environment deterioration, poor meat quality of the native chicken, etc. caused by the misuse of antibiotics and other drugs. Meanwhile, the production method can improve feed utilization efficiency, promote growth of the native chickens and improve mouthfeel of the native chicken meat. In addition, the immunocompetence feed has the following advantages: a low production cost, a simple technology, a wide range of application, safety and high efficiency.
