Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for enhancing forage digestibility in ruminants, such as physical and chemical treatments, are costly and pose environmental risks, while concentrated feeds can lead to rumen acidosis due to lactate accumulation, reducing milk fat production and overall productivity in dairy cattle.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If physical treatment methods (immersion, pulverization, pressure steam treatment) are used to enhance forage digestibility, then the digestibility of forage is improved, but processing costs increase significantly
Solution Approach 1:
The patent replaces mechanical physical treatment methods with biological treatment methods using microorganisms (cellulolytic enzymes and specific bacterial strains). Instead of using mechanical energy for pulverization or pressure steam treatment, the invention uses biological catalysts (enzymes and microbes) to degrade cellulose and improve digestibility, thereby reducing mechanical processing costs while maintaining or enhancing digestive efficiency
Solution Approach 2:
The invention changes the approach from physical parameter modification (mechanical breakdown, heat treatment) to biological parameter modification (microbial activity, enzymatic degradation). By introducing specific microorganisms that produce cellulolytic enzymes, the patent transforms the digestion process from a purely physical/mechanical process to a biological one, improving digestibility through biochemical pathways rather than mechanical energy input
2Productivity
If chemical treatment methods (sodium hydroxide, urea, ammonia, lime) are used to enhance forage digestibility, then the digestibility of forage is improved, but processing costs increase and environmental contamination occurs
Solution Approach 1:
The patent replaces chemical treatment methods with biological treatment methods. Instead of using chemical reagents like sodium hydroxide, urea, or ammonia to modify forage structure, the invention uses microorganisms and their produced enzymes to naturally degrade cellulose and hemicellulose. This substitution eliminates the need for harmful chemicals, preventing environmental contamination while achieving improved digestibility through biological degradation pathways
Solution Approach 2:
The invention uses readily available, biodegradable microorganisms and enzymes as temporary agents that perform their function and then naturally decompose. Unlike persistent chemical treatments that remain in the environment, the biological agents used in this patent are consumable and environmentally benign, breaking down after use without leaving harmful residues, thus avoiding long-term environmental contamination
3Use of energy by moving object
If large amounts of concentrated feeds are fed to replenish energy, then energy requirements are met, but lactate concentration increases causing rumen pH decrease and acidosis
Solution Approach 1:
The patent introduces specific microorganisms (Bacillus subtilis and Bacillus licheniformis) as intermediary agents in the rumen ecosystem. These microorganisms act as mediators that facilitate the conversion of excess lactate into acetate through enzymatic action. By introducing these intermediary organisms, the system transforms the harmful metabolic pathway (lactate accumulation) into a beneficial one (acetate production), thereby preventing acidosis while maintaining energy supply from concentrated feeds
Solution Approach 2:
The invention converts the harmful substance (excess lactate causing acidosis) into a beneficial substance (acetate, a valuable rumen volatile fatty acid). By introducing microorganisms that produce lactate-degrading enzymes, the patent transforms the harmful metabolic byproduct of concentrated feed digestion into a useful energy source and pH buffer, thereby converting the harmful effect of high-energy feeding into a beneficial outcome that prevents acidosis while maintaining energy supply
4Productivity
If chemical treatment methods are used to enhance forage digestibility, then the digestibility of forage is improved, but soil contamination and physiological disruption occur
Solution Approach 1:
The patent replaces chemical treatment methods with biological treatment methods. Instead of using chemical reagents that can leach into soil and cause contamination, the invention uses microorganisms and their produced enzymes to naturally degrade cellulose and hemicellulose. This substitution eliminates chemical runoff and soil contamination risks while achieving improved digestibility through biological degradation pathways that are environmentally benign
