Natural plant-fermented feed additive used for feeds and capable of improving eggshell color of brown-egg laying hen, and preparation method thereof

Abstract

The invention discloses a natural plant-fermented feed additive used for feeds and capable of improving the eggshell color of a brown-egg laying hen, and a preparation method thereof, belonging to thetechnical field of feed additives. The natural plant-fermented feed additive is mainly prepared from the following raw materials by weight: 25 to 45 parts of Gynostemma pentaphyllum, 30 to 55 parts of paper mulberry leaves, 20 to 35 parts of turmeric, 15 to 35 parts of motherwort, 10-25 parts of licorice roots and 0.1 to 0.3 part of composite microbial powder, wherein the composite microbial powder is a prepared by mixing Aspergillus niger, Vinolevure, lactic acid bacteria, Bacillus subtilis and Bacillus licheniformis. The natural plant-fermented feed additive of the invention has the functions of improving body immunity and replenishing qi and blood, is mainly used for improving the eggshell color of the brown-egg laying hen, and can significantly increase egg output and the digestion and utilization rate of feeds.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a fermented natural feed plant feed additive for improving the eggshell color of brown eggs and a preparation method thereof. Background technique [0002] In recent years, fermented feed has been favored by laying hen farmers because of its rich nutrition and unique efficacy. The main advantage of fermented feed is to organically combine the function of its original feed material with the effect of microbial fermentation to achieve the goal of "1+1﹥2". [0003] Natural forage plants are a very important category of feed materials. Most of the feed materials not only have nutritional effects, but also have the effect of improving the body's immunity, which plays a very important role in improving the production performance of laying hens. [0004] Eggshell color is one of the most important appearance indicators of eggs, especially for brown-shelled eggs. Eggs...

Problems solved by technology

[0005] At present, there are many methods to improve the color of eggshells, but the actual clinical effect is not ideal

Among them, the use of food coloring to improve the color of eggshells is the most effective method. However, most food colorings are artificially synthesized and the production process is relatively complicated, resulting in high prices. People have been trying to find a new method to improve the color of eggshells.
