Mineral Content Testing in Feed (Ca, P, K, Mg)
The mineral content testing of feed is a crucial component in ensuring animal health and growth. Calcium (Ca), phosphorus (P), potassium (K), and magnesium (Mg) are essential nutrients for animals as they play vital roles in bone development, energy metabolism, muscle function, and overall health.
Calcium is necessary for the formation of bones and teeth, muscle contraction, nerve signal transmission, and blood clotting. Phosphorus supports cellular processes like DNA synthesis and repair, and it works alongside calcium to maintain strong bones. Potassium is vital for regulating fluid balance within cells and transmitting signals through nerve and muscle tissue. Magnesium is involved in over 300 enzymatic reactions including energy production and supporting proper muscle function.
Testing the mineral content ensures that feeds meet the nutritional requirements set by international standards such as ISO, ASTM, EN, IEC, and others. For instance, according to ISO 12576-4:2020, the testing method for calcium in animal feed should be validated against the specific matrix of interest.
Our laboratory follows a precise protocol to perform these tests:
- Sampling: A representative sample is taken from each batch of feed ensuring homogeneity. This is critical as variations within batches can significantly affect test results.
- Precipitation: Calcium and magnesium are precipitated by adding appropriate reagents to the feed sample, while phosphorus and potassium are determined using flame or atomic absorption spectrophotometry (FAAS).
- Digestion: The feed samples undergo digestion in a mixture of acids at elevated temperatures. This step is essential for releasing the minerals from their organic complexes.
- Analytical Measurement: The digested sample is then analyzed using flame or atomic absorption spectrophotometry to quantify the levels of Ca, P, K, and Mg.
The precision and accuracy of these tests are paramount for compliance with international standards. Our laboratory adheres strictly to ISO 17025 requirements ensuring traceability and reliability in all test results.
Regular testing not only ensures compliance with regulations but also helps in optimizing feed formulations, reducing waste, and improving animal performance. By accurately measuring the mineral content, we can identify deficiencies or excesses that could negatively impact animal health and productivity.
