Enkephalin (Type II)
The main components of the Fengtai series of products are Bacillus subtilis and its metabolites.
Product Introduction
Feng肽 series products are mainly composed of Bacillus subtilis and its metabolites. Feng肽 is a variety of active peptides efficiently produced in Bacillus subtilis. These peptides were isolated from specific beneficial bacteria in natural environments 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 have been continuously domesticated. Feng肽 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 diarrhea rate, improve survival rate, lower feed-to-meat ratio, and enhance immunity.
۞ Breeding pigs: Improve sow intestinal health, reduce vertical transmission from sows, and increase piglet survival rate, health, and weaning weight.
۞ Poultry: Inhibit Escherichia coli and Salmonella, reduce the incidence of inflammation caused by pathogenic bacteria, increase poultry daily weight gain, and lower the feed-to-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 fish and shrimp mortality, enhance immunity, improve late growth rate, and reduce feed coefficient.
Sensory
Powdery, consistent color, no mildew, deterioration, caking, or foreign smell or odor.

Product Features
1. Unique mechanism, does not produce drug resistance
Feng肽 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 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 Feng肽 activity; Treatment at 8 gradients of PH 2.0-9.0 for 2 hours each has no effect on Feng肽 activity; 5mg/L pepsin and trypsin at PH 2.5 and PH 8.0 respectively in a 37°C water bath for 4 hours has no effect on Feng肽 activity.
4. Safe and efficient, green and environmentally friendly
Feng肽 is a new generation of bioactive peptides, containing no antibiotic components, and conforms to the current national standards for antibiotic prohibition and restriction.
