AI Technical Summary

Technical Problem

Existing technologies for processing Caragana korshinskii into feed cannot effectively degrade lignocellulose and anti-nutritional factors, resulting in low digestibility, poor palatability, environmental pollution, and high costs, making it difficult to achieve high-value utilization.

Method used

The process employs a combination of physical crushing and fine grinding with Ganoderma lucidum mycelium fermentation. The enzyme system of the mycelium degrades lignin and tannins, while corn and wheat bran are added to improve pellet formation. This avoids high-temperature and high-pressure treatment and preserves nutrients.

Benefits of technology

It significantly improved the crude protein content, digestibility, and palatability of Caragana korshinskii feed, while reducing lignin and tannin content, achieving efficient utilization and environmentally friendly treatment of Caragana korshinskii resources and reducing costs.

Abstract

This invention belongs to the field of resource utilization and feed processing technology, and discloses a method for preparing Caragana korshinskii feed based on mycelial fermentation. This method utilizes a combination of physical crushing, fine grinding, and microbial fermentation to achieve efficient degradation of anti-nutritional factors without the need for high temperature and pressure. The addition of microorganisms directionally degrades lignin, reducing the lignin and tannin content in Caragana korshinskii, improving palatability, and increasing the crude protein content and digestibility of the feed. Corn and wheat bran are selected as auxiliary materials to improve pellet formation. The low-temperature pelleting process avoids the destruction of nutrients such as amino acids, maximizing the preservation of the feed's nutritional value.
