Embodiment 1
[0018] A grass carp feed comprises the following components by weight:
[0019] 150 parts of peanut cakes; 80 parts of fishmeal; 20 parts of fermented products of green duckweed; 40 parts of fermented products of brewer's grains; 2 parts of vegetable oil; 5 parts of compound enzyme preparations; , cellulase, pectinase, amylase or a mixture of two or more.
[0020] The fermented green duckweed is obtained by adding photosynthetic bacteria to fresh green duckweed and fermenting for 3-5 days.
[0021] The preparation method of described brewer's grain fermented product, comprises the following steps:
[0022] (1) Cook the wet beer grains at 95-98°C for 25-30min;
[0023] (2) Add photosynthetic bacteria to the cooked beer wet grains for fermentation. The fermentation conditions are: the inoculation amount of photosynthetic bacteria is 0.8%; the fermentation temperature is 32°C; the fermentation time is 70h; the light power of fermentation is 60W;
[0024] (3) ...
