Poultry Feed Starch Digestibility Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for optimizing poultry feed efficiency and egg production using starch sources are ineffective due to the avian gastrointestinal system's limitations in digesting starch, leading to reduced health, production, and feed efficiency.
Innovation Solution
Measuring starch digestibility by gastrointestinal microorganisms and formulating poultry diets to specific targets using the Gastrointestinal Digestible Starch Component (GDSC) to manipulate the dietary GI digestible starch component within certain weight percent ranges, optimizing meat, egg, or feed production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If starch intake is increased to improve digestibility, then energy availability is improved, but health and feed efficiency are reduced
Solution Approach 1:
The patent applies parameter changes by measuring starch digestibility using in vitro assays with gastrointestinal microorganisms and formulating diets to specific GDSC targets. This transforms the approach from simply increasing starch quantity to precisely controlling starch digestibility parameters, thereby improving energy availability while maintaining health and feed efficiency through optimized digestibility levels rather than excessive starch intake
2Productivity
If starch digestibility is increased to improve production, then meat and egg production are improved, but feed efficiency is reduced
Solution Approach 1:
The patent implements feedback by using in vitro starch digestibility measurements with gastrointestinal microorganisms to guide diet formulation. This feedback mechanism allows optimization of starch sources and processing methods to achieve specific GDSC targets, ensuring that starch is maximally digestible for improved meat and egg production while minimizing energy loss through inefficient feed utilization
Solution Approach 2:
The invention changes the parameter focus from total starch content to gastrointestinal digestible starch component (GDSC). By measuring and formulating to specific GDSC targets, the system improves productivity through better starch utilization while maintaining feed efficiency, as birds receive optimally digestible starch rather than indigestible excess

Function Achieved in This Case
Improves poultry egg production, meat production, and feed efficiency by adjusting the digestibility of starch in poultry feed, maximizing energy intake and essential nutrients while minimizing health issues.
Implementation Method 1
the availability of starch in grains to enzymatic digestion can affect both feed efficiency and egg production
Implementation Method 2
Starch includes both amylose and amylopectin molecules which in turn are broken down to glucose for availability to poultry
