[0027] Example 1
[0028] A preparation method of chicken powder additive for fish feed, including the following steps:
[0029] (1) Preparation of chicken skeleton powder:
[0030] a. Use knives to decompose the chicken skeleton for later use;
[0031] b. Put the chicken skeleton treated in operation a into the pressure cooker, heat to keep the temperature in the pressure cooker at 115°C, and take out the chicken skeleton for use after 1h of high temperature and high pressure cooking;
[0032] c. Carry out secondary colloid refining treatment on the chicken skeleton after operation b, and obtain the slurry for use after completion;
[0033] d. Filter the slurry after operation c, rinse the filtered powder with water and dry it for later use;
[0034] e. Immerse the powder obtained in operation d into treatment liquid A, heat to maintain the temperature of treatment liquid A at 40°C, and apply ultrasonic irradiation treatment, and filter out the powder after 17 minutes for use; each of th...
