Since the addition of antibiotics in feed is completely prohibited, and because resveratrol has various biological functions such as anti-oxidation and immunity enhancement, it has become one of the potential substitutes for antibiotics.
Resveratrol is a natural plant extract. It belongs to non-flavonoid polyphenolic compounds. Resveratrol is contained in more than 70 kinds of plants or their fruits, such as grapes, peanuts, pomegranates, knotweed, mulberries, blueberries, etc.
Why Use Resveratrol For Feed?
1. Improve production performance
Resveratrol to the diet can improve the feed intake and daily weight gain of chickens and pigs.
2. Antioxidant
Resveratrol can improve the antioxidant capacity of livestock and poultry, and its antioxidant function mainly depends on the following aspects:
Resveratrol can increase the activity of antioxidant enzymes.
It has the ability to scavenge hydroxyl, superoxide and metal-induced free radicals, and its ability to scavenge ONOO- is stronger than vitamin C.
Resveratrol can exert antioxidant effects through a non-enzymatic antioxidant system.
3. Improve immunity
Resveratrol has immunomodulatory effects. Resveratrol can promote the growth of animal immune organs.
Resveratrol can promote the growth of immune organs, stimulate lymphocyte proliferation, enhance the phagocytic function of macrophages, and increase the level of antibodies and cytokines, thereby improving the cellular immune function, humoral immune function, and natural immune function of animals. immunity.
4. Antibacterial and antiviral
Resveratrol has bacteriostatic effects on both bacteria and fungi. The exertion of antibacterial effect may inhibit the growth of bacteria by destroying the formation of bacterial biofilm, inhibiting the protein expression of the fission protein FtsZ and the formation of Z-ring.
Antiviral activity is related to inhibiting viral replication and acting on the immune system of animals, increasing the expression of antiviral factors such as IFN-γ and IL-12, and enhancing the host's antiviral ability.
5. Protects Gut Health
Resveratrol has a protective effect on the intestinal barrier. Ocludin is an important tight junction protein. It plays an important role in maintaining epithelial cell polarity, regulating intercellular adhesion, and receiving and transmitting cell signals.
Summary
Resveratrol has various biological functions such as anti-inflammatory, antibacterial and antiviral functions, and antioxidant functions, and its application in livestock and poultry can improve its production performance. Resveratrol has the potential to be used as an alternative to antibiotics today, when antibiotics are banned from being used as additives in animal production.
