Broiler Feed Formulation Using Net Energy and Heat Increment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current poultry feed formulation methods rely on metabolizable energy (ME) rather than net energy (NE), which does not accurately account for heat increment losses, leading to inefficient energy utilization and misleading calorie efficiency calculations, particularly for rapid-growing broilers.
Innovation Solution
The process uses Arkansas net energy (ArkNE) formulations that calculate net energy requirements by combining net energy of maintenance (NEm) and net energy of gain (NEg), utilizing dual-energy X-ray absorptiometry (DEXA) and indirect calorimetry to determine body composition and heat production, providing a more accurate prediction of energy needs for broiler production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metabolizable energy (ME) is used for feed formulation, then calculation is simple and easy, but energy utilization accuracy is poor and heat increment losses are not accounted for
Solution Approach 1:
The patent transitions from using metabolizable energy (ME) parameters to net energy (NE) parameters by subtracting heat increment losses. This parameter change transforms the energy calculation from a crude measure to a precise measure that reflects actual energy available for production, resolving the contradiction between calculation simplicity and energy utilization accuracy.
2Measurement precision
If classic net energy (NE) method is used, then heat increment is accounted for, but protein accretion is penalized and calorie efficiency is misleading
Solution Approach 1:
The patent segments net energy into two distinct components: net energy for maintenance (NEm) and net energy for gain (NEg). This segmentation allows separate accounting for different energy uses, preventing the misleading penalization of protein accretion that occurs in classic NE methods. The segmentation preserves information about production type by tracking energy allocation to specific functions.
Solution Approach 2:
The patent introduces body composition change as an intermediary measurement to determine NEg. By using DEXA scans to measure actual body composition changes and calculating the energy required for those specific changes, the system creates an accurate mediator that reflects actual production outcomes rather than relying on classic NE calculations that penalize protein accretion.
3Measurement precision
If dual-energy X-ray absorptiometry (DEXA) and indirect calorimetry are used, then body composition and heat production are accurately measured, but system complexity increases
Solution Approach 1:
The patent employs DEXA scans to measure body composition changes, allowing the system to self-determine the actual energy requirements based on measured body composition rather than relying on theoretical calculations. The birds essentially measure their own energy requirements through their actual body composition changes, reducing the need for complex external measurement systems while maintaining high precision.
4Measurement precision
If net energy of gain (NEg) is calculated based on body composition, then energy for production is accurately determined, but measurement time and resources increase
Solution Approach 1:
The patent takes preliminary action by using DEXA scans to measure body composition at specific intervals and pre-calculating the energy required for observed body composition changes. This preliminary measurement approach allows the system to establish accurate NEg values before feed formulation, reducing the need for repeated measurements and minimizing time loss while maintaining precision.
