ISO 26307 Protein Digestibility Testing in Compound Feed
The International Organization for Standardization (ISO) defines ISO 26307:2018 as a standard that provides methods to determine the apparent digestibility coefficient of protein in compound feed. This method is critical in the food and feed sector, particularly when ensuring nutritional values meet regulatory standards while optimizing animal health and performance.
The test assesses how efficiently an animal can utilize dietary proteins by measuring nitrogen excreted in urine and feces after ingestion of a known amount of feed. The primary outcome provides insights into the quality of protein sources used in compound feeds, aiding in formulation adjustments to enhance nutritional efficiency.
Protein digestibility is not just about the quantity but also the quality. Animals require specific amino acids for growth and development; hence, a high-quality protein source should be easily digested. This test helps evaluate whether these sources are readily available in the feed as intended.
The testing process involves feeding a defined amount of compound feed containing nitrogen to an animal or using in vitro methods simulating digestive processes. The collected excreta is analyzed for total and volatile nitrogen, allowing calculation of the digestibility coefficient based on the difference between ingested and excreted nitrogen.
This information is invaluable for feed manufacturers who aim to balance their formulations precisely. By accurately measuring protein digestibility, they can select appropriate raw materials and optimize blends to meet both regulatory requirements and market demands effectively.
| Sample Preparation | Test Procedure | Results Reporting |
|---|---|---|
| Ensure homogeneity of feed samples and adjust to appropriate moisture content. | Determine the amount of nitrogen in ingested and excreted materials using appropriate analytical techniques like Dumas combustion or Kjeldahl method. | Calculate digestibility coefficients using the difference between ingested and excreted nitrogen, expressed as a percentage. |
The accuracy of these measurements is paramount. Precision in sample handling, consistent feeding protocols, and accurate analytical techniques contribute significantly to reliable results.
- Ensure that the feed samples are representative of the compound feed batch.
- Feed animals under controlled conditions to minimize variability due to environmental factors.
- Use validated analytical methods for nitrogen determination.
The standardization process through ISO ensures consistency across laboratories, making it easier for stakeholders in the industry to compare results and adhere to global standards. Compliance with this protocol is crucial not only for maintaining product quality but also ensuring adherence to international regulations governing feed safety and efficacy.
Industry Applications
The application of ISO 26307 extends beyond just laboratory testing; it plays a pivotal role in several sectors within the food & feed industry:
- Animal Nutrition: Ensures that formulated feeds meet nutritional requirements while minimizing waste and enhancing animal health.
- Regulatory Compliance: Helps manufacturers comply with international standards for protein digestibility, ensuring products are safe and effective.
- R&D Innovation: Supports research into developing new feed formulations that improve digestibility coefficients.
The results of this test are also useful in identifying potential improvements to existing feeds or discovering novel feed additives. By understanding how efficiently animals utilize different protein sources, researchers can innovate and develop better products tailored specifically for various species and life stages.
| Species | Potential Benefits of ISO Digestibility Testing |
|---|---|
| Cattle | Optimizes feed efficiency leading to reduced costs and improved milk or meat production. |
| Poultry | Improves egg quality and quantity, contributing positively to farm productivity. |
| Pig | Increases lean meat percentage and overall growth rates enhancing profitability for producers. |
This standardized approach supports sustainable practices by promoting the use of efficient feed formulations, thereby reducing resource consumption and waste generation. In essence, ISO 26307 serves as a cornerstone for responsible and effective food & feed production across various sectors.
