Feed Additive Composition with Xylanase and Beta-Glucanase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in effectively utilizing high-fiber, low-nutritive alternative ingredients in animal feeds, particularly for poultry and swine, as they contain non-starch polysaccharides that are indigestible and limit nutrient intake, necessitating technologies to efficiently break down dietary fiber and mitigate anti-nutritional properties.
Innovation Solution
Combining specific direct-fed microbials (DFMs) with xylanase and β-glucanase enzymes to optimize the degradation of plant cell wall components, particularly hemicellulose, into short-chain fatty acids (SCFAs) in the gastrointestinal tract, enhancing energy utilization and nutrient absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If alternative high-fiber ingredients are used in animal feeds, then cost-effectiveness is improved, but digestibility and nutrient utilization deteriorate due to high non-starch polysaccharide content
Solution Approach 1:
The patent combines multiple enzymes (xylanase, β-glucanase, cellulase) with direct-fed microbials (probiotics) into a single feed additive composition. This merging creates a synergistic system where enzymes provide immediate hydrolysis of non-starch polysaccharides while microbials contribute to sustained digestion and gut health, thereby improving digestibility without sacrificing the cost-effectiveness of using alternative ingredients.
Solution Approach 2:
The invention uses a composite feed additive composition containing both enzymatic and microbial components. The composite structure allows the product to address multiple limitations of high-fiber ingredients simultaneously: enzymes break down anti-nutritional factors while microbials enhance nutrient utilization and mitigate negative effects, resolving the contradiction between cost-effectiveness and digestibility.
2Adaptability or versatility
If non-starch polysaccharides are present in high amounts, then alternative ingredient utilization is improved, but energy and nutrient utilization deteriorate due to indigestibility
Solution Approach 1:
The enzyme components perform preliminary hydrolysis of non-starch polysaccharides before they reach the animal's digestive system. By pre-breaking down complex fibers into simpler sugars and oligosaccharides, the system makes alternative ingredients more可利用 while ensuring that the released nutrients can be efficiently utilized for energy, thus resolving the contradiction between ingredient versatility and energy utilization.
Solution Approach 2:
The direct-fed microbials act as intermediaries that further process the hydrolyzed products from enzymes. These microbials ferment available carbohydrates to produce short-chain fatty acids, which serve as an additional energy source for the animal. This intermediary action bridges the gap between high fiber content and effective energy utilization.
3Quantity of substance
If fiber content is increased, then alternative ingredient application is improved, but nutrient intake is limited due to anti-nutritional properties
Solution Approach 1:
The patent converts the anti-nutritional properties of high fiber content into beneficial effects. The enzyme-microbial system transforms indigestible non-starch polysaccharides into digestible forms, and the microbial fermentation produces beneficial short-chain fatty acids. This converts the harmful anti-nutritional factors into useful energy sources and gut health promoters, allowing high fiber content without nutrient loss.
4Device complexity
If xylanase alone is used for fiber degradation, then process simplicity is improved, but degradation efficiency deteriorates due to insufficient fiber breakdown
Solution Approach 1:
The patent merges multiple enzymatic functions (xylanase, β-glucanase, cellulase) with microbial action into a single composition. This combination addresses the limitations of using xylanase alone by providing complementary enzyme activities that target different components of plant cell walls, achieving comprehensive fiber degradation while maintaining practical simplicity of application as a single feed additive product.
