Compound feed additive and application thereof

Abstract

The invention provides a compound feed additive. The compound feed additive comprises 10-20 parts of a plant essential oil compound, 10-20 parts of medium-chain fatty acids, 40-50 parts of an embedding wall material, and 5-15 parts of starch, wherein the plant essential oil compound comprises 10-20 parts of cretian origanum oil, 10-20 parts of eugenol, 10-30 parts of vanillin, 10-30 parts of carvacrol, 10-30 parts of geraniol, 10-30 parts of cinnamaldehyde, and 0-0.5 part of polysorbate 20. The invention further provides a preparation method and application of the feed additive. The plant essential oil is embedded, so that the plant essential oil can resist high temperature during granulation, and the amount of the plant essential oil sent to central sections and end sections of small intestines of animals is increased. In addition, the medium-chain fatty acid is added to the feed additive, and is in synergistic reaction with the plant essential oil in the feed additive, so that the animal growth can be effectively promoted, the feed transformation efficiency can be improved, and the disease incidence rate can be reduced.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry or feed, and in particular relates to a compound feed additive and its application. Background technique [0002] Plant essential oil has antibacterial and antiviral activity, can improve the palatability of feed, improve the digestive function and immune function of animal intestines, has the potential to replace antibiotics, and has been widely used in medicine, cosmetics and food preservation. For example, eugenol is a colorless or pale yellow oily liquid, mostly separated from clove oil, and can also be prepared by chemical synthesis. Cinnamaldehyde is purified from the aromatic oil obtained by distilling the bark, branches and leaves of the Lauraceae plant cinnamon, and can also be synthesized artificially. Carvacrol is rich in medicinal vanilla plants Pogostemon cablin and Thymus vulgaris, usually obtained by treating the essential oils of these two plants with alkaline solution, t...

AI Technical Summary

Problems solved by technology

This technique is time consuming, expensive and limited in output

[0004] Most of the unembedded plant essential oils are rapidly absorbed and metabolized in the upper gastrointestinal tract after oral administration, and only a very small amount can reach the middle and end of the small intestine, resulting in its biological activity (such as antibacterial activity) can't be fully utilized
