The experiment was to study the stability of feed additive lysozyme dimer in influencing factors and accelerated test, determined the validity period of the product through long-term test. Three batches of lysozyme dimer samples were taken for influencing factor test (high temperature test, high humidity test and light test), accelerated test and long-term test, the moisture, dimer content and enzyme activity of lysozyme dimer were detected as inspection indicators. The results showed that the lysozyme dimer was relatively stable in the influence factor test, accelerated test and long-term test. The validity period of the product was preliminarily determined to be 12 months after the validity period prediction analysis. The experiment indicates that lysozyme dimer is relatively stable. The product can be packed in compound paper bags and stored in dry and ventilated places. [ABSTRACT FROM AUTHOR]

Seabuckthorn is rich in polysaccharides, flavonoids, tannins, terpenoids, fatty acids, vitamins, and other active components. It has biological functions such as antioxidant, antibacterial, anti-inflammatory, anti-tumor, liver-protecting, and cholagogic, which can enhance the immunity and antioxidant function of livestock and poultry, improve growth performance, and improve the quality of livestock and poultry products. Adding seabuckthorn residue, seeds, leaves or extracts to diet can promote the production of pigs, sheep, dairy cows and broilers to varying degrees, reduce feed costs and improve the economic benefits of breeding, but the active components and molecular mechanisms of seabuckthorn promoting livestock and poultry production are unclear. In this paper, the active components, biological functions, and application of seabuckthorn in livestock and poultry production were summarized, which provided a reference for the mechanism research, production application and development of seabuckthorn promoting livestock and poultry production.

Stevia rebaudiana is rich in glycosides and polyphenolic bioactive substances, which have the function of antibacterial, antioxidant and lowering blood glucose and lipids. With the rapid development of animal husbandry, Stevia rebaudiana and its extracts have been widely used in livestock and poultry production. In the process of stevioside production and processing, a large number of by-products, stevia residues, are produced. Stevia residues have the potential to be used as unconventional feed raw materials. In the paper, the application progress of active substances and by-products of Stevia rebaudiana in livestock and poultry production is summarized, which can provide a reference for the research and application of Stevia rebaudiana as a functional feed additive in livestock production.

Vine tea is a medicinal and food plant, which is rich in flavonoids. The main components of vine tea are dihydromyricetin and myricetin. Rattan tea and its main active components have antioxidant, antibacterial and immunomodulatory functions. The use of probiotics to ferment vine tea for biotransformation can improve the active ingredient content and biological activity of rattan tea. In recent years, the application of vine tea as a new feed additive in animal production has attracted wide attention. Therefore, this paper briefly summarizes the active components and biological activity of vine tea, and outlined the biotransformation of vine tea through probiotics and its application in animal production, to provide a reference for the efficient utilization of vine tea in animal production.
