Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If lactic acid bacteria are used as probiotics in ruminant animals, then feed efficiency and growth performance may be improved, but the effects are mixed and the mode of action is unclear
Solution Approach 1:
The patent identifies and utilizes specific functional parameters of Lacticaseibacillus rhamnosus FNZ142, including its ability to produce bacteriocins, modulate volatile fatty acid profiles, and inhibit methanogenesis. By focusing on these specific mechanistic parameters rather than general probiotic effects, the invention achieves consistent and reliable improvements in feed efficiency and growth performance.
Solution Approach 2:
The patent employs Lacticaseibacillus rhamnosus FNZ142 as an intermediary microorganism that mediates between feed intake and productive output. The strain acts as a functional mediator by producing bacteriocins that inhibit harmful bacteria, modulating the rumen microbiome to reduce methane production, and improving nutrient utilization, thereby consistently enhancing feed efficiency and growth.
2Object-generated harmful factors
If lactic acid bacteria are used to reduce methane emissions from ruminants, then greenhouse gas emissions may be reduced, but the success has been limited
Solution Approach 1:
The patent converts the harmful methane production process into a beneficial outcome by utilizing Lacticaseibacillus rhamnosus FNZ142 to inhibit methanogenic bacteria. The strain produces bacteriocins that specifically target and inhibit methanogens, thereby converting the harmful methane emission process into a reduced emission outcome, achieving reliable methane reduction.
Solution Approach 2:
The patent changes the functional parameters of the rumen microbiome by introducing Lacticaseibacillus rhamnosus FNZ142, which produces bacteriocins that inhibit methanogenesis. This parameter change in microbial community composition and function leads to consistent and reliable reduction in methane emissions, overcoming the limitations of previous probiotic approaches.
3Productivity
If conventional feed compositions are used, then basic nutrition is provided, but feed efficiency and growth potential are not fully optimized
Solution Approach 1:
The patent introduces Lacticaseibacillus rhamnosus FNZ142 as a functional intermediary that mediates energy conversion efficiency in the rumen. The strain produces bacteriocins that inhibit harmful bacteria, modulates the microbiome to reduce methane production (which represents energy loss), and improves overall nutrient utilization, thereby optimizing both growth rate and energy conversion efficiency.
Solution Approach 2:
The patent replaces the passive mechanical digestion system with an active biological modulation system. By introducing Lacticaseibacillus rhamnosus FNZ142, the invention substitutes the purely mechanical feed conversion process with a biologically active system that produces bacteriocins, modulates microbiome composition, and enhances metabolic efficiency, leading to optimized growth and energy utilization.
