Abstract

The invention discloses an animal feed addictive and preparing method, which comprises the following parts: adopting ginkgo leaf as raw material, utilizing superior bacteria to ferment, decomposing ginkgo leaf into easy digestion and adsorption material, exposing active component in the ginkgo leaf.

Description

technical field [0001] The invention relates to a feed additive and a preparation method thereof, in particular to an animal feed additive fermented from ginkgo biloba as a main raw material and a preparation method thereof, belonging to the field of feed. Background technique [0002] The intensive and specialized animal husbandry in developing countries has just started, and the compound feed industry is still being established like mushrooms after rain. The demand for feed additives is increasing day by day. In addition, developing countries are facing the difficulties of tight food supply and insufficient feed. It is necessary to vigorously develop feed additives. The current application of feed additives in our country is too simplistic, and it is necessary to develop compound multi-dimensional feed additives to make full use of their benefits. [0003] Ginkgo biloba is the dry leaf of the ancient relic plant Ginkgo biloba. Ginkgo biloba not only has the nutrition of g...
