Experimental example gained aquatic biological feed of the present invention feeding effect is in table 1
Choose 8 fry fields, every fry scene amasss 1 mu, is divided into 8 groups at random, is set to control group A, control group B control group C, embodiment 1 group, embodiment 2 groups, embodiment 3 groups, embodiment 4 groups, embodiment 5 groups;
Control group A uses bacterium fermented feed, and described bacterium fermented feed is remove phytase in the present invention, other compositions and the constant gained feed of method;
Control group A uses enzyme preparation feed, and described enzyme preparation feed is remove bacillus subtilis, candida utili and lactobacillus acidophilus in the present invention, other compositions and the constant gained feed of method;
Control group C uses mixed fodder, and described mixed fodder is control group A bacteria used thereby fermented feed and control group B used enzyme preparation feed simple physical mixture;
Embodiment 1-5 group uses embodiment of the present invention 1-5 gained aquatic feeds.
Table 1 gained aquatic biological feed of the present invention is to fry growth experimental result
Note: compare with A control group, B control group and C control group, * P<0.05
As seen from the above table, control group C is compared with control group A, control group B, and growth cycle and survival rate all do not have marked change.And the aquatic biological feed of gained of the present invention, compare with control group A, B with C, growth cycle obviously shortens, and survival rate significantly improves.
Control group C is compared with control group A, control group B, and the pH anoxic number of days in situation and water that fluctuates all does not have marked change.And the aquatic biological feed of gained of the present invention, compare with control group A, B with C, pH fluctuates and in water, anoxic number of days all obviously reduces, and water quality situation is obviously stablized.
