The application discloses an
antibacterial peptide mutant and application thereof, the
amino acid sequence of the
mutant is shown in any one of SEQ ID NO:1 or SEQ ID NO:2.The
antibacterial peptide has good antibacterial and bacteriostatic performance, and the application thereof in preparing microbial inhibitors and in feed additives is also provided.The
feed additive comprises the
antibacterial peptide, wherein the antibacterial
peptide can replace the
growth promoting effect of
antibiotics, and the effect is rapid and stable without residue; meanwhile, the
feed additive also comprises gamma-
aminobutyric acid and
vitamin C, which can eliminate the reduction of feed intake caused by high temperature and
high humidity, relieve
heatstroke symptoms such as no sweating and rapid
breathing,
resist stress, have a good regulating effect on various physiological and
pathological changes, reduce and neutralize toxins, and enhance the detoxification capacity of liver.
