Piglet Feed Bacterial Enzyme Synergistic Fermentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current animal feed phosphorus utilization efficiency is low, leading to environmental pollution and nutritional deficiencies in pigs due to the low digestibility of phytate phosphorus, which is not effectively utilized by piglets lacking phytase enzymes.
Innovation Solution
A piglet feed based on a bacterial enzyme synergistic fermentation process using Lactobacillus plantarum, Pediococcus pentosaceus, and Aspergillus niger strains combined with protease, amylase, lipase, and cellulase enzymes, applied to a fermentation substrate, significantly improving phosphorus availability and overall nutrient utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If phytase is added to hydrolyze phytic acid in plant feed, then phosphorus availability is improved, but the improvement rate is limited and cannot fully resolve phosphorus utilization issues
Solution Approach 1:
The patent combines multiple microorganisms (Lactobacillus plantarum, Bacillus subtilis, Aspergillus oryzae) with multiple enzymes (phytase, protease, amylase, lipase, cellulase) into a composite preparation that works synergistically. This merging approach overcomes the limitation of single phytase addition by creating a multi-functional system that simultaneously performs phosphorus release and comprehensive nutrient digestion, thereby significantly improving phosphorus utilization beyond what single phytase can achieve.
Solution Approach 2:
The invention uses a composite fermentation preparation containing multiple microbial strains and enzyme types rather than a single enzyme or microorganism. This composite material approach allows the system to perform multiple functions simultaneously: phytase releases phosphorus from phytate, while protease, amylase, lipase, and cellulase break down other macronutrients, creating a synergistic effect that greatly enhances overall phosphorus availability and nutrient utilization.
2Quantity of substance
If inorganic phosphorus sources are added to meet pig growth needs, then phosphorus supply is sufficient, but phosphorus excretion increases causing environmental pollution
Solution Approach 1:
The fermented feed preparation contains microorganisms and enzymes that actively work within the pig's digestive system to release phosphorus from phytate on-site. This self-service mechanism allows the feed to provide its own phosphorus through biological hydrolysis, reducing the need for additional inorganic phosphorus supplements and minimizing phosphorus waste in excreta, thereby decreasing environmental pollution.
Solution Approach 2:
The patent changes the chemical state of phosphorus from bound phytate phosphorus to free phosphorus through enzymatic hydrolysis during fermentation and digestion. This parameter change in phosphorus availability allows for reduced inorganic phosphorus addition while meeting nutritional requirements, thereby reducing phosphorus excretion and environmental impact.
3Quantity of substance
If phytate phosphorus is used in feed, then phosphorus content is high, but digestibility and utilization are low due to interaction with anti-nutrient substances
Solution Approach 1:
The patent applies preliminary enzymatic hydrolysis through fermentation with phytase and other enzymes before the feed is consumed by pigs. This preliminary action breaks down phytate phosphorus and anti-nutrient substances in advance, converting bound phosphorus into available forms and reducing interactions that would otherwise hinder digestion, thereby improving both phosphorus availability and overall nutrient digestibility.
Solution Approach 2:
The fermented preparation acts as an intermediary that mediates between phytate phosphorus and the pig's digestive system. The enzymes in the preparation (phytase, protease, amylase, lipase, cellulase) serve as intermediaries that break down complex compounds into absorbable forms, facilitating phosphorus release and reducing negative interactions with anti-nutrient substances, thereby improving digestibility and utilization.
