EN 15914 Determination of Gross Energy in Animal Feed
The European Standard EN 15914 provides a method for determining gross energy (GE) content in animal feed materials. This test is crucial for ensuring the nutritional quality and consistency of feeds, which directly impacts animal health and performance.
Gross energy refers to the total heat released when a substance undergoes combustion. In animal feeds, it represents the overall calorific value available to animals. Accurate determination ensures that feed manufacturers can provide products tailored to specific dietary requirements, thereby supporting optimal growth, reproduction, and productivity in livestock.
EN 15914 specifies a bomb calorimeter as the primary apparatus for this test. A bomb calorimeter is designed to measure the heat released when a sample burns completely under controlled conditions. The procedure involves several steps:
- Sampling and preparation of the feed material.
- Weighing an appropriate amount of the sample into a combustion crucible.
- Inserting the crucible into the bomb calorimeter, ensuring it is tightly sealed to prevent air from entering during combustion.
- Adding an excess of oxygen and igniting the feed material inside the bomb.
- Measuring the temperature rise of the water surrounding the bomb after combustion.
The accuracy of this method depends on precise sample preparation, calibration of the calorimeter, and consistent experimental conditions. The standard also outlines acceptance criteria based on repeatability and reproducibility. Repeatability is typically within ±2% for laboratories with a good quality management system.
Understanding the gross energy content helps in formulating feeds that meet specific nutritional needs. This includes balancing macronutrients like proteins, fats, and carbohydrates to ensure they support growth without causing obesity or deficiencies. For instance, diets high in fat may be suitable for certain types of livestock but could lead to health issues if not balanced correctly.
| Step | Description | Value (MJ/kg) |
|---|---|---|
| Weighing sample | 0.5 g of feed material | 12.3 MJ/kg |
| Bomb calorimeter temperature rise | 21°C post-combustion |
