Embodiment 1
[0016] Embodiment one: mussel meat (100kg), egg lecithin (8kg), cod oil (10kg), 50% vitamin E (1kg), vitamin C (0.5kg) are first used papain (activity is 1,000,000) in proportion Unit) After 3 hours of constant temperature enzymolysis at 70-72°C in a hot and cold tank, add 100 grams of ethoxyquinoline, filter to obtain a hydrolyzate, pump it into a QZR-150 high-speed centrifugal spray dryer for spray drying to obtain a Micro-granule feed (properties as shown in the table), nozzle speed: 15000r / min, inlet temperature: 200~211℃, outlet temperature: 100~103℃. After feeding grouper fry, there is no significant difference in growth and survival rate compared with feeding rotifers and artemia, which achieves a good effect of partially replacing biological bait.
Embodiment 2
[0017] Embodiment two: squid meat (100kg), soybean lecithin (8kg), cod oil (10kg), 50% vitamin E (1kg), vitamin C (0.5kg), spirulina powder (1kg) are first used in pancreas according to the proportion Protease (with an activity of 500,000 units) was enzymolyzed in a hot and cold tank at 60-62°C for 3 hours, then 100 grams of ethoxyquinoline was added, the hydrolyzate was filtered, and pumped into a QZR-150 high-speed centrifugal spray dryer Spray-dry to obtain a micro-granule feed (properties as shown in the table), nozzle speed: 18000r / min, inlet temperature: 200-211°C, outlet temperature: 100-103°C. After feeding grouper fry, there is no significant difference in growth and survival rate compared with feeding rotifers and artemia, and also achieved a better effect of partially replacing biological bait.
