Feed Additive Composition with Protease and Probiotics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current feed additive compositions for animals do not effectively address the need for reducing antibiotic use in animal feed while improving production performance and gut health, as they lack a balanced combination of bacterial strains and proteases that can effectively inhibit pathogens and enhance nutrient digestion.
Innovation Solution
A feed additive composition comprising a direct-fed microbial with a combination of specific bacterial strains such as Bacillus subtilis, Bacillus licheniformis, and Bacillus amyloliquefaciens, along with a protease like subtilisin, which is designed to improve nutrient digestibility, reduce pathogen growth, and enhance gut health.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antibiotics are used in animal feed to prevent disease and improve performance, then animal health and production performance are improved, but antibiotic resistance develops and public health concerns arise
Solution Approach 1:
The patent changes the fundamental parameter of disease prevention from chemical (antibiotics) to biological (probiotics and enzymes) mechanisms. The feed additive composition uses live bacterial cultures and enzymatic digestion to improve animal health through enhanced nutrient absorption and competitive exclusion of pathogens, rather than direct antimicrobial action.
Solution Approach 2:
The patent introduces probiotic bacteria and digestive enzymes as intermediary substances that mediate between feed and animal health. These intermediaries work by modulating the gastrointestinal environment, enhancing nutrient availability, and competing with pathogens, thereby providing an indirect but effective alternative to direct antibiotic intervention.
2Ease of manufacture
If feed additive compositions use simple ingredients to reduce cost, then manufacturing cost decreases, but effectiveness in improving nutrient digestibility and inhibiting pathogens is insufficient
Solution Approach 1:
The patent employs a composite feed additive composition that integrates multiple functional components: probiotic bacteria (such as Bacillus subtilis, Lactobacillus species), digestive enzymes (proteases, amylases, cellulases), and prebiotic substrates. This composite approach synergistically combines pathogen inhibition, nutrient digestion enhancement, and gut health promotion, achieving superior effectiveness compared to single-ingredient additives while remaining cost-effective through natural and fermentable components.
3Object-affected harmful factors
If feed additives focus only on pathogen inhibition to reduce disease, then disease prevention improves, but nutrient digestibility and overall performance are not adequately enhanced
Solution Approach 1:
The patent designs a multi-functional feed additive composition where probiotic bacteria and enzymes simultaneously perform multiple functions: (1) inhibiting pathogens through competitive exclusion and antimicrobial substance production, (2) enhancing nutrient digestibility through enzymatic breakdown of complex carbohydrates, proteins, and fats, (3) producing vitamins and growth factors, and (4) modulating gut microbiota balance. This universal approach addresses both disease prevention and performance enhancement in a single integrated system.
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 composition significantly improves nutrient digestibility, feed conversion ratio, and overall animal performance by inhibiting pathogens and promoting beneficial bacteria, thereby reducing the need for antibiotics and enhancing growth and health.
Implementation Method 1
a feed additive composition comprising a direct-fed microbial with a combination of specific bacterial strains such as Bacillus subtilis, Bacillus licheniformis, and Bacillus amyloliquefaciens, along with a protease like subtilisin
Implementation Method 2
DFMs can be used as antimicrobial replacements and, thus, reduce the need for antibiotics in animal feed. DFMs may also compete with and inhibit the growth of pathogens
Implementation Method 3
DFMs may also compete with and inhibit the growth of pathogens, stimulate immune function and modulate microbial balance in the gastronintestinal tract
