Polypeptide (Type I)
The main components of the Fengtai series of products are Bacillus subtilis and its metabolites.
Product Introduction
Fengtai series products are mainly composed of Bacillus subtilis and its metabolites. Fengtai is a variety of active peptides efficiently produced in Bacillus subtilis. These peptides were isolated from specific beneficial bacteria in the natural environment through high-throughput screening technology by the Feed Engineering Research Center of the Ministry of Agriculture and Rural Affairs of China and Academician Qiao Shiyan's team, and continuously domesticated. Fengtai has a strong inhibitory effect on most Gram-negative bacteria and some Gram-positive bacteria, and is a stable and novel bioactive peptide beneficial to intestinal health.
Product Efficacy
۞Suckling piglets: Reduce the diarrhea rate of suckling piglets, improve the survival rate, reduce the feed-meat ratio, and enhance immunity.
۞ Breeding pigs: Improve sow intestinal health, reduce vertical transmission of sows, improve piglet survival rate, health, and weaning weight.
۞ Poultry: Inhibit Escherichia coli and Salmonella, reduce the incidence of inflammation caused by pathogenic bacteria, increase the daily weight gain of poultry, and reduce the feed-meat ratio.
۞ Laying hens: Improve egg production rate, reduce inflammation such as peritonitis and salpingitis caused by pathogenic bacteria, and reduce watery diarrhea.
۞ Aquatic animals: Prevent bacterial diseases, reduce the mortality rate of fish and shrimp, enhance immunity, improve the growth rate in the later stage, and reduce the feed conversion ratio.
Guaranteed Analysis of Product Composition
Bacillus subtilis ≥1.0*108，Moisture ≤12.0%.
Product Features
1. Unique mechanism, no drug resistance
Fengtai can act on the cell membranes of harmful microorganisms, causing changes in cell permeability, leading to membrane disintegration or osmotic pressure imbalance. It can also bind to intracellular nucleic acids, affecting protein expression and interfering with the reproduction of pathogenic bacteria.
2. Broad antibacterial spectrum
It has an inhibitory effect on most pathogenic Escherichia coli, Salmonella, Vibrio, and other common Gram-negative bacteria, as well as Staphylococcus aureus, Clostridium perfringens, and other Gram-positive bacteria, but it has no killing effect on intestinal lactic acid bacteria and other probiotics.
Strain | Sensitivity to non-peptides | Strain | Sensitivity to non-peptides |
Escherichia coli | ＋＋＋＋ | Staphylococcus aureus | ＋＋＋＋ |
Salmonella | ＋＋＋ | Clostridium perfringens | ＋＋＋＋ |
Vibrio parahaemolyticus | ＋＋＋＋ | Lactic acid bacteria | × |
3. Heat-resistant, acid-base resistant, protease-resistant
Boiling water bath for 4 hours has no effect on Fengtai activity; PH 2.0-9.0 is treated in 8 gradients for 2 hours respectively, which has no effect on Fengtai activity; 5mg/L pepsin and trypsin are treated at PH 2.5 and PH 8.0 respectively at 37 degrees Celsius for 4 hours, which has no effect on Fengtai activity.
4. Safe and efficient, green and environmentally friendly
Fengtai is a new generation of bioactive peptides, does not contain antibiotic components, and complies with current national standards for antibiotic prohibition and restriction.
