Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing methane production in ruminant animals, such as using antibiotics, halogen compounds, or probiotics, are either ineffective, pose safety risks, or increase costs, and there is a need for a feed additive that can efficiently and safely minimize methane emissions without impacting livestock productivity.
Innovation Solution
A feed additive composition containing diallyl disulfide, alliin, nitrate, berberine, and eucalyptus oil, which can be added to the feed without additional treatment processes, effectively reducing methane production in the ruminant stomach through a synergistic effect, thereby minimizing environmental impact while maintaining livestock productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If antibiotics are added to feed to reduce methane production, then methane gas production is reduced, but safety issues arise due to harmful residues in the human body
Solution Approach 1:
The patent replaces persistent antibiotics with natural compounds (ginger extract, chive extract, conjugated linoleic acid) that are metabolized and eliminated from the animal body, avoiding long-term residue accumulation. These natural additives provide temporary methane inhibition effects without the safety concerns of antibiotic residues.
Solution Approach 2:
The patent utilizes natural compounds found in common food plants (ginger, chive) and established feed additives (conjugated linoleic acid) to achieve methane reduction. These substances are already recognized as safe for animal consumption and human health, converting the harm of methane emissions into a beneficial application of natural products.
2Object-generated harmful factors
If protozoa are eliminated from the ruminant stomach to reduce methane production, then methane gas production is reduced, but cellulose levels decrease
Solution Approach 1:
Instead of eliminating protozoa entirely, the patent changes the chemical environment in the rumen by introducing natural compounds (ginger extract, chive extract, conjugated linoleic acid) that selectively inhibit methanogenic bacteria. This parameter change allows protozoa to remain for cellulose digestion while reducing their partnership with methanogens in producing methane.
3Object-generated harmful factors
If halogen compounds are added to feed to reduce methane production, then methane gas production is reduced, but safety issues arise due to halogen accumulation in livestock
Solution Approach 1:
The patent replaces halogen compounds with naturally occurring organic compounds (ginger extract, chive extract, conjugated linoleic acid) that are metabolized and excreted from the animal body. These natural additives provide methane inhibition effects without accumulating in animal tissues, eliminating the safety concerns associated with halogen accumulation.
4Object-generated harmful factors
If probiotics are fed to reduce methane production, then methane gas production is reduced, but inconsistency arises in probiotic fermentations and strains added during every experiment
Solution Approach 1:
The patent uses standardized feed additives (ginger extract, chive extract, conjugated linoleic acid) with consistent chemical compositions and well-defined mechanisms of action. Unlike probiotics that vary by strain and fermentation batch, these homogeneous additives provide reliable and reproducible methane reduction effects across different experiments and applications.
5Object-generated harmful factors
If feed composition requiring additional preparation processes is used to reduce methane production, then methane gas production is reduced, but purchase costs increase due to high preparation costs
Solution Approach 1:
The patent combines multiple methane-inhibiting natural compounds (ginger extract, chive extract, conjugated linoleic acid) into a single integrated feed additive formulation. This merged product can be directly incorporated into feed without requiring separate preparation steps for each component, reducing both preparation complexity and associated costs while maintaining effective methane reduction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The feed additive composition significantly reduces methane production, with methane reduction rates ranging from 21.9% to 56.2%, and when used in milking cows, it increases milk production without negatively affecting fermentation or productivity, demonstrating a safe and efficient solution to environmental methane emissions.
Implementation Method 1
The feed consumed by ruminant animals is decomposed into volatile fatty acids, hydrogen, carbon dioxide, and ammonia nitrogen by fermentation of anaerobic microorganisms (bacteria, protozoa, and fungi) in the ruminant stomach, and the hydrogen and carbon dioxide are converted to methane by methanogenic bacteria.
