Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid feeds for weaned piglets suffer from weaning stress syndrome due to nutritional, physiological, and digestive issues, and existing fermented feeds do not effectively address these problems, leading to decreased feed intake and increased susceptibility to illness.
Innovation Solution
A preparation method involving enzymatic hydrolysis and bio-fermentation of feed ingredients, combined with grinding and homogenization, to create a bio-fermented liquid and emulsion feed that mimics breast milk nutrition, enhances digestibility, and prevents stratification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dry solid feed is used for weaned piglets, then feed intake decreases due to sudden change from liquid breast milk, but providing liquid feed would require complex formulation to match breast milk nutrition
Solution Approach 1:
The patent changes the physical state parameter of the feed from solid to liquid form, and modifies chemical composition parameters by using enzymatic hydrolysis to break down complex macromolecules into simpler components. This creates a liquid feed that mimics breast milk properties while being easier for weaned piglets to accept and digest.
Solution Approach 2:
The patent replaces mechanical grinding and physical processing with biochemical processes (enzymatic hydrolysis and fermentation). Enzymes substitute for mechanical breakdown, and microbial fermentation substitutes for complex chemical formulation, simplifying the overall feed preparation system while maintaining nutritional quality.
2Productivity
If conventional solid feed with starch and plant protein is provided, then production efficiency improves, but digestive problems occur due to low digestive enzyme content and activity
Solution Approach 1:
The patent performs preliminary enzymatic hydrolysis and fermentation processing on the feed before it reaches the piglet. Complex proteins are pre-digested into peptides and amino acids, and starch is pre-breakdown into simpler carbohydrates. This preliminary action reduces the digestive burden on piglets with insufficient endogenous enzymes, preventing digestive problems while maintaining high productivity.
Solution Approach 2:
The patent introduces enzymes and probiotics as intermediary substances that facilitate digestion. These additives act as mediators between the complex feed and the immature digestive system of piglets, breaking down difficult-to-digest components and promoting healthy gut flora, thereby ensuring both productivity and digestive health.
3Productivity
If early weaning is implemented to improve shed utilization, then production efficiency increases, but weaning stress syndrome occurs with diarrhea and low immunity
Solution Approach 1:
The patent provides the piglet digestive system with a head start through preliminary enzymatic processing of the feed. By pre-digesting complex components into easily absorbable forms before the piglet encounters them, the feed compensates for the premature separation from maternal protection, reducing stress-induced digestive failures and immune suppression.
Solution Approach 2:
The patent uses controlled fermentation by probiotics to convert potentially harmful substances into beneficial compounds. The fermentation process transforms complex proteins into simpler peptides, produces organic acids that inhibit pathogenic bacteria, and generates vitamins and growth factors. This converts the challenge of early weaning stress into an opportunity to enhance feed quality and piglet health.
