Abstract

The invention discloses a feed additive based on antibacterial peptide and a preparation process thereof. The feed additive comprises, by weight, 10-15 parts of antibacterial peptide, 6-12 parts of ligustrum lucidum extract, 5-10 parts of Chinese herbal medicine extract, 3-5 parts of cordyceps taishanensis solid fermentation culture, 2-4 parts of enzymatic pine needle meal, 4-7 parts of soybean peptide, 0.5-1.5 part of selenium enriched yeast powder, 0.4-0.8 part of cellulase, 0.5-1 part of complex amino acid, 0.3-0.5 part of lysine chelated copper. The components of the ligustrum lucidum extract, the Chinese herbal medicine extract, the cordyceps taishanensis solid fermentation culture, the enzymatic pine needle meal and the like are compounded on the basis of the antibacterial peptide. By means of the synergistic effect of the components, the antibacterial capability of the feed additive is improved, the immunity of livestock and poultry is improved, the physical fitness of the livestock and poultry is enhanced, the feed utilization efficiency of the livestock and poultry is improved, the grow rate is increased, and the breeding efficiency is improved accordingly.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to an antimicrobial peptide-based feed additive and a preparation process. Background technique [0002] In the process of modern livestock and poultry farming, in order to prevent and treat animal diseases, excessive antibiotic products are often used to ensure the health of animals, but the excessive use of antibiotics often leads to the decline in the quality of animal meat products and their products and the enhancement of antibiotic resistance, resulting in transmission through the food chain. Human health is also severely affected by the problem of antibiotics. [0003] In order to reduce the problem of antibiotic residues in livestock and poultry breeding, improve productivity, and reduce the pollution of the livestock and poultry industry to the environment, the development of feed additives has become a hot spot in recent years. Among them, feed additives based on a...
