Ruminally Undigested Fiber Fraction Analysis for Feed Ration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for formulating animal feed rations fail to effectively control the rate and extent of fiber and starch digestion in the rumen, leading to variations in milk production, dry matter intake, and feed efficiency in lactating animals, as they rely on crude analyses that do not account for ruminal digestion processes.
Innovation Solution
A system and method that analyze feed components to calculate a ruminal undigested fiber fraction, using in vitro and in situ testing to determine ruminal starch and fiber digestibility, and adjust feed formulations to achieve targeted digestion rates and extents, thereby improving milk production and reducing feed costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If crude analysis methods are used for feed formulation, then the formulation process is simple and fast, but the control over ruminal digestion rate and extent is poor, leading to variations in milk production and feed efficiency
Solution Approach 1:
The patent applies parameter changes by transitioning from crude analysis parameters to rumen undigested neutral detergent fiber (RUNDNDF) parameters. This involves measuring and formulating based on specific digestibility parameters (RUNDNDF percentages) that directly control ruminal digestion rates, thereby achieving both precision in digestion control and operational feasibility through standardized measurement protocols
2Manufacturing precision
If rumen undigested neutral detergent fiber (RUNDNDF) analysis is implemented, then the control over starch and fiber digestion is improved, but the analysis complexity and cost increase
Solution Approach 1:
The patent uses RUNDNDF as an intermediary parameter that bridges the gap between feed composition and ruminal digestion outcomes. By measuring RUNDNDF content in feed ingredients and using it as a formulation parameter, the system achieves precise control over starch and fiber digestion without requiring complex direct measurement of ruminal processes, thus reducing analysis complexity while maintaining precision
3Productivity
If traditional feed formulation methods are used, then feed costs are lower due to simpler processing, but milk production efficiency and dry matter intake vary significantly
Solution Approach 1:
The patent implements feedback by using RUNDNDF analysis results to continuously optimize feed formulations. By measuring the actual rumen undigested fiber content and comparing it with target values, the system adjusts formulation parameters to achieve optimal digestion rates, thereby improving milk production efficiency and reducing energy loss through better feed conversion, which ultimately lowers feed costs per unit of milk produced

AI summary
Systems and methods measure ruminal undigested fiber fractions in a feed by sampling forages and grains from available feed sources, analyzing the samples to determine a starting NDF value and an ending NDF value after ruminal digestion, calculating a ruminal undigested NDF fraction based thereon; and calculating a feed ration using the ruminal undigested NDF fraction and feeding rates of the analyzed samples. Systems and methods reduce feed costs or improve milk production by analyzing feed components in a feed ration fed to a lactating ruminant, comparing the analyzed results with a feed formulation stored in memory, where the feed formulation is for controlling a rate and extent of fiber and starch digestion in the rumen, and reformulating the feed ration based on the comparison. The rate of fiber digestion may be controlled based on a determination of the ruminal undigested NDF fraction of the analyzed feed components.
