Solution Overview

Problem

Existing feed ration formulations based on the nutritive values of unprocessed forages become less accurate when the forages are macerated, as maceration increases digestibility and nutrient absorption, altering the effective nutritive value.

Innovation Solution

A method and system that determine the initial nutritive value of a forage material, macerate it using a mechanical macerator, and then correct the initial nutritive value based on the actual amount of maceration, using a ration controller to define a corrected nutritive value and adjust the feed ration formulation accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If forage material is macerated to increase digestibility and nutrient absorption, then animal production increases, but the accuracy of existing ration formulations becomes less accurate

Engineering Contradiction:
Improveanimal productionVSAvoidration formulation accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system uses maceration sensors to detect the actual degree of maceration and feeds this information back to the ration controller, which then adjusts the ration formulation to maintain accuracy despite variations in maceration intensity

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system changes the parameters used for ration formulation from standard nutritive values to corrected nutritive values that account for the actual degree of maceration, thereby maintaining formulation accuracy under varying maceration conditions

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If the degree of maceration varies, then nutrient absorption increases, but the consistency of ration formulation decreases

Engineering Contradiction:

AI summary

A method of preparing a feed ration (22) for an animal (24) includes determining an initial nutritive value of a forage material (26), and then macerating the forage material (26) with a mechanical macerator (30). An actual amount of maceration of the forage material (26) achieved by the mechanical macerator (30) is then determined with a macerator sensor (50). The initial nutritive value may then be corrected to define a corrected nutritive value that accounts for the change in digestibility of the forage material (26) caused by maceration. A formulation for the feed ration (22) may then be defined or determined based on the corrected nutritive value of the forage material (26).
