Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feed compositions for livestock, particularly those using Aspergillus fermentation, face challenges in ensuring uniform and rapid fermentation, leading to suboptimal body weight gain and feed conversion ratios, and require lengthy storage solutions.
Innovation Solution
A feed composition utilizing Aspergillus niger and Lactic acid bacteria, with a pH of 5.5 or less and high water content, is produced as a liquid feed additive, facilitating rapid and uniform fermentation, reducing feed conversion ratios, and enabling long-term storage and cost-effective animal raising.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If water content is reduced to prevent decay, then storage life is improved, but fermentation uniformity and speed deteriorate
Solution Approach 1:
The patent changes the water content parameter from low (conventional) to high (70% or more), which enables uniform and rapid fermentation while the acidic environment (pH 5.5 or less) provides preservation, achieving both fast fermentation and storage stability
Solution Approach 2:
The patent uses a composite fermentation system combining Aspergillus and Lactic acid bacteria, where Aspergillus rapidly ferments carbohydrates and Lactic acid bacteria produce acid for preservation, achieving both fast fermentation and long storage life simultaneously
2Duration of action of stationary object
If water content is reduced to prevent decay, then storage life is improved, but fermentation time increases
Solution Approach 1:
The patent increases water content to 70% or more, which accelerates fermentation to complete within 24 hours while the resulting acidic environment ensures long-term storage stability, resolving the time-storage contradiction
Solution Approach 2:
The patent uses Aspergillus to continuously and rapidly ferment carbohydrates into sugars and organic acids, maintaining high metabolic activity in the high-water environment, completing fermentation quickly while the produced acid ensures subsequent storage stability
3Ease of manufacture
If conventional feed is used, then production is simple, but body weight gain and feed conversion ratio are suboptimal
Solution Approach 1:
The patent combines Aspergillus and Lactic acid bacteria in a dual-fermentation system, where Aspergillus breaks down carbohydrates into simple sugars and amino acids, and Lactic acid bacteria convert these into organic acids and nutrients, creating a highly nutritious feed that significantly improves body weight gain while maintaining production simplicity
Solution Approach 2:
The patent changes the pH parameter to 5.5 or less through Lactic acid bacteria fermentation, creating an acidic environment that preserves nutrients and enhances digestibility, leading to improved body weight gain and feed conversion ratio
