Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing pressure to reduce antibiotic use in animal feed has led to a need for alternatives that can effectively inhibit pathogenic bacterial populations in the gastrointestinal tracts of animals, such as birds, while promoting improved health metrics like bodyweight gain, reduced mortality, and decreased pathogen shedding.
Innovation Solution
A multi-strain direct fed microbial bacterial consortium comprising specific strains of Lactobacillus reuteri, L. salivarius, L. agilis, and L. gallinarum, which produce organic acids and are administered to animals to inhibit pathogens like Salmonella, Escherichia coli, and Clostridium perfringens, while enhancing gut health and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If antibiotics are used to control pathogenic bacterial populations, then pathogen reduction is achieved, but antibiotic resistance develops and gut health is compromised
Solution Approach 1:
The patent converts the harmful effect of antibiotics into a beneficial alternative by using organic acid-producing bacteria. These bacteria produce organic acids (lactic acid, acetic acid, propionic acid) that naturally inhibit pathogenic bacteria, replacing antibiotics with a beneficial microbial mechanism that reduces resistance development while maintaining pathogen control.
Solution Approach 2:
The patent introduces organic acid-producing bacteria as an intermediary substance between the diet and pathogenic bacteria. These bacteria metabolize carbohydrates to produce organic acids, which then act as the active inhibiting agents against pathogens, mediating the control mechanism without requiring direct antibiotic intervention.
2Object-affected harmful factors
If antibiotics are used to prevent necrotic enteritis, then disease prevention is achieved, but gut microbiota balance is disrupted
Solution Approach 1:
The patent employs organic acid-producing bacteria that perform self-service by naturally producing their own protective mechanism. These bacteria metabolize dietary carbohydrates to generate organic acids, which automatically inhibit pathogenic bacteria and maintain gut microbiota balance without external antibiotic intervention, thereby preventing necrotic enteritis while preserving microbial diversity.
Solution Approach 2:
The patent changes the chemical parameter of the gut environment by introducing organic acids produced by beneficial bacteria. This parameter change (increased organic acid concentration) creates an unfavorable environment for pathogenic bacteria while maintaining beneficial microbiota, thus preventing disease without disrupting overall microbial balance.
3Productivity
If antibiotics are used to improve growth performance, then feed conversion ratio improves, but pathogen resistance increases
Solution Approach 1:
The patent converts the harmful byproduct of antibiotic use (resistant pathogens) into a beneficial outcome by using organic acid-producing bacteria. These bacteria provide the same growth performance benefits as antibiotics through natural metabolic pathways, improving feed conversion ratio while eliminating the generation of antibiotic-resistant strains.
Solution Approach 2:
The patent substitutes the mechanical/chemical action of antibiotics with a biological mechanism. Instead of using antibiotics to directly kill or inhibit pathogens, the system uses organic acid-producing bacteria that naturally produce inhibitory substances through metabolism, replacing the artificial chemical mechanism with a natural biological process that avoids resistance development.
