Resveratrol can enhance animal immunity and improve animal production performance. As people pay more and more attention to food safety and enhance their awareness of environmental protection, it has become an inevitable trend to ban antibiotics as feed additives completely, and finding their substitutes is a research hotspot in the animal husbandry industry. In recent years, studies have reported that resveratrol has anti-cancer, anti-inflammatory, antioxidant, and lipid-lowering effects as a new type of feed additive.

At present, there are many international reports on the effect of adding resveratrol to poultry diets, and good results have been achieved. The addition to poultry diets can improve growth performance and enhance immunity. It can improve the quality of livestock products and increase production efficiency.

The study found that resveratrol can improve the immune performance of broilers, increase the thymus, spleen and bursa index, significantly increase the serum IgG and IgM levels, and significantly reduce the serum lactate dehydrogenase (LDH) activity. It can be seen that the application in poultry production has achieved good results. However, the research on poultry production is still relatively small, and its intrinsic mechanism of action remains to be further elucidated.

Giant knotweed root extract has received more and more attention due to its versatility, high efficiency and other properties. In recent years, as the biological functions of resveratrol have been reported one after another, resveratrol has become a research hotspot in the field of animal nutrition. With the deepening of research, it will show great application value in the feed industry.
