Abstract

The invention discloses an application of litsea cubeba residues in a feed additive used for improving a microflora in animal intestines, and provides a composite feed additive composed of the litsea cubeba residues and a compound enzyme preparation. The litsea cubeba residues are generated after litsea cubeba oil is extracted. The composite feed additive can remarkably improve diversity and richness of poultry hindgut microfloras.

Description

technical field [0001] The invention belongs to the field of compound feed additives, and in particular relates to the application of litsea cubeba slag as a feed additive for improving animal intestinal microbial flora and a compound feed additive. Background technique [0002] With the rise of the "return to nature" craze, the plant extract industry has grown rapidly. The plant extract industry is an emerging industry that provides pure natural plant extract raw materials for the feed, food and beverage, nutritional additives, cosmetics, daily chemical and pharmaceutical industries. . my country is rich in plant resources and is a big country of plant extracts. At present, there are more than 1,000 manufacturers engaged in plant extracts in my country. In 2006, the export volume reached 477 million US dollars, and the annual growth rate was steadily above 15%. However, with the development of my country's plant extraction industry, there is also a problem that cannot be i...
