The invention discloses a mandarin fish
feed additive as well as a preparation method and application thereof, belongs to the technical field of
aquaculture, and solves the problems that a conventional feed in the prior art is serious in
water pollution, hypoxia stress of
fish larvae, low in
immunity, dysfunctional in gastrointestinal tracts and the like, and low in fry
survival rate. The mandarin fish
feed additive comprises the following components in percentage by
mass: 45%-56% of enzymolysis fresh minced fillet, 8%-12% of gradient activated
zeolite powder, 10%-20% of
soybean meal or / and
cottonseed meal, 2%-4% of an
immunopotentiator, 1.5%-2% of compound probiotics, 6%-8% of
fish oil or / and
krill oil and 4%-5% of a premix. When the mandarin fish
feed additive is used for culturing mandarin fish, the activity of serum
peroxidase of the mandarin fish can be improved, the activity of
glutathione peroxidase is improved, and the content of
malondialdehyde is reduced; the
selenium deposition of the liver can be increased, and the intestinal
flora can be optimized; the
survival rate of the mandarin fish can be improved.
