[0002] In modern animal husbandry, feed is a key factor affecting livestock growth, immunity and meat quality. Traditional livestock feed often contains large amounts of chemically synthesized antibiotics, growth hormones and feed additives to promote livestock growth, prevent diseases and improve feed conversion. However, the residues of these chemicals in livestock not only pose potential hazards to the health of the livestock themselves, such as causing the production of drug-resistant bacteria and immune dysfunction, but also pass through the food chain to humans, causing food safety issues, such as antibiotic residues leading to human allergic reactions, increased drug resistance and other health risks.

[0003] In addition, as consumers pay more and more attention to food safety and quality, the demand for natural, green and residue-free livestock products is growing. Therefore, the development of new, green, safe and health-promoting feed has become a research hotspot in the field of animal husbandry.

[0004] As a traditional precious flower and Chinese medicinal material, peony is rich in resources. Different parts of peony, such as root bark (moutan bark), petals, seeds, etc., contain a variety of biologically active ingredients, including paeoniflorin, paeonol, flavonoids, volatile oils, etc. These ingredients have multiple pharmacological effects such as antibacterial and anti-inflammatory, antioxidant, antiviral, immune regulation, and improvement of cardiovascular function. For example, paeonol has significant antibacterial, anti-inflammatory and antioxidant activities, which can effectively inhibit the growth and reproduction of various pathogens, reduce inflammatory reactions, remove free radicals in the body, and protect cells from oxidative damage; paeoniflorin has the effects of regulating immune function and promoting blood circulation. Applying peony to livestock feed is expected to utilize its pharmacological effects to enhance livestock immunity, reduce the occurrence of diseases, improve feed utilization, and improve meat quality, produce green livestock products with health functions, meet market demand, and improve breeding efficiency.
