Solution Overview
Problem
Existing forage cutting processes are not adaptable to the type and quality of forage, leading to inefficient energy use, variable digestibility, and suboptimal fiber length selection that affects animal health and production efficiency.
Innovation Solution
A process that measures specific parameters like aNDF/lignin ratio, uNDF240, and leaf-to-stem ratio to determine optimal cutting lengths for different forage types, using NIR spectrometry for precision, and adjusts cutting times based on these parameters to enhance digestibility and ruminant activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If forage is cut to a fixed length regardless of type, then the cutting process is simple and fast, but digestibility varies and ruminant activity is not optimized
Solution Approach 1:
The cutting length is made dynamic and adaptable based on forage characteristics. The system determines optimal cutting length by measuring forage parameters (leaf-to-stem ratio, aNDF, lignin content) and adjusting the cutting length accordingly, rather than using a fixed length for all forage types.
Solution Approach 2:
The invention changes the cutting length parameter based on measured forage properties. By measuring parameters like leaf-to-stem ratio, aNDF, and lignin content, the system adjusts the cutting length parameter to optimize digestibility and ruminant activity for each specific forage type.
2Manufacturing precision
If forage cutting time is extended to improve digestibility, then fiber length and digestibility are optimized, but energy consumption increases
Solution Approach 1:
The system performs preliminary measurement of forage characteristics (leaf-to-stem ratio, aNDF, lignin content) before cutting to determine the optimal cutting length in advance. This allows the cutting process to be optimized from the start, avoiding unnecessary extended cutting times and associated energy consumption.
Solution Approach 2:
The invention implements a feedback mechanism where measured forage parameters (leaf-to-stem ratio, aNDF, lignin content) are used to determine and adjust the cutting length. This feedback loop ensures that cutting time and energy are optimized based on actual forage characteristics rather than using fixed, potentially excessive cutting times.
3Manufacturing precision
If forage parameters are measured precisely to determine optimal cutting length, then digestibility and ruminant activity are optimized, but measurement complexity and time increase
Solution Approach 1:
The invention replaces complex mechanical measurement systems with optical/NIR (Near Infrared) measurement technology. This allows for rapid, non-contact measurement of forage parameters (leaf-to-stem ratio, aNDF, lignin content) without complex mechanical handling or preparation, reducing both measurement time and system complexity.
Solution Approach 2:
The system uses NIR spectroscopy as an intermediary method to indirectly measure forage composition parameters. Instead of directly measuring complex chemical compositions, the NIR technique provides rapid estimation of leaf-to-stem ratio, aNDF, and lignin content, simplifying the measurement process while maintaining precision.
4Manufacturing precision
If cutting length is reduced to improve digestibility, then fiber breakdown is enhanced, but ruminant activity stimulation decreases
Solution Approach 1:
The invention adjusts the cutting length parameter dynamically based on measured forage characteristics. By considering parameters like leaf-to-stem ratio and lignin content, the system determines an optimal cutting length that balances digestibility enhancement with adequate fiber length to maintain ruminant chewing activity and overall reliability of the feeding system.

AI summary
Process for cutting a forage for farm animals, which comprises a step of arranging at least one dose of forage and a first step of measuring a first parameter (PI) indicative of the quantity of indigestible fiber contained in the dose of forage. In addition, the process comprises a first step of comparing the first parameter (PI) with a discrimination value (D), which identifies at least one first composition interval (11), with a first cutting length (LI) associated therewith, and a second composition interval (12), with a second cutting length (L2) associated therewith. In addition, in the first comparison step with the first parameter (PI) in the first composition interval (11), the first cutting length (LI) is selected; and with the first parameter (PI) in the second composition interval (12), the second cutting length (L2) is selected. The process also comprises a first step of setting a target cutting length (Lf), determined as a function of at least one between the first cutting length (LI) and the second cutting length (L2) selected, in a cutting apparatus, and a first cutting step, in which the cutting apparatus is actuated with the dose of forage at its interior in order to obtain a dose of cut forage.
