Embodiment 1

[0020] Add copper acetate to absolute ethanol containing dihydromyricetin, the molar ratio of copper acetate to dihydromyricetin is 1.2:1, adjust the pH value to 6.5, stir and reflux at 50°C, react for 4 hours, and obtain a precipitate. Wash the precipitate with ethanol and dry to obtain the dihydromyricetin-copper complex.

Embodiment 2

[0022] Add copper acetate to absolute ethanol containing dihydromyricetin, the molar ratio of copper acetate to dihydromyricetin is 1.4:1, adjust the pH value to 7.5, stir and reflux at 70°C, and react for 10 hours to obtain a precipitate. Wash the precipitate with ethanol and dry to obtain the dihydromyricetin-copper complex.

Embodiment 3

[0024] Add zinc acetate to absolute ethanol containing dihydromyricetin, the molar ratio of zinc acetate to dihydromyricetin is 1.2:1, adjust the pH value to 6.5, stir and reflux at 50°C, react for 4 hours, and obtain a precipitate. Wash the precipitate with ethanol and dry it to obtain the dihydromyricetin-zinc complex.

Abstract

The invention discloses application of a dihydromyricetin metal complex serving as a feed additive. The dihydromyricetin metal complex serving as the feed additive is added into the feed of live stock, so that growth of the live stock is promoted, meat quality is improved, eggshell hardness is improved, milk production is promoted, use of antibiotic is reduced, and the dihydromyricetin metal complex is healthy and environment-friendly. In addition, the invention also discloses a preparation method for the dihydromyricetin metal complex. The dihydromyricetin metal complex prepared by the method has the biological activity of dihydromyricetin; and more metal elements with active effects on animal nutrition can be introduced under the condition that the total quantity of the dihydromyricetinis not changed.

Description

technical field [0001] The invention relates to the application of the dihydromyricetin metal complex, in particular to the application of the dihydromyricetin metal complex as a feed additive. Background technique [0002] In the process of livestock production, trace elements have an important impact on the health of livestock, especially copper, zinc, iron, manganese and other elements. For example, manganese, zinc and copper are directly involved in the formation of bone matrix and eggshell, and zinc is involved in the keratinization, healing and hardening of epithelial tissue, regulating the immune system and promoting the synthesis of testosterone, insulin and adrenal glucocorticoid, improving the survival rate and Weaners are heavy, iron prevents anemia and manganese reduces fat deposits and improves feed conversion and carcass quality. However, studies have shown that the absorption and utilization effect of animal organisms on chelated metal ions by organic substan...
