This test method is a gravimetric method used to determine crude fiber content in oilseed meals, animal feeds, and related agricultural products. Crude fiber consists of the indigestible portion of plant material, primarily cellulose and lignin, remaining after digestion with dilute acid and alkali.
This test method is a gravimetric method used to determine the crude fiber content in oilseed byproducts, such as soybean meal, cottonseed meal, canola meal, and other plant-based feed materials. Crude fiber represents the indigestible portion of the sample that remains after chemical digestion, primarily composed of cellulose and lignin, but excluding more soluble fiber… Continue reading Crude Fiber [Oilseed Byproducts]
This test method is a combustion method for determining crude protein in soybean meal, using high‑temperature combustion in pure oxygen to release nitrogen that is then measured and converted to protein. It is also the officially designated crude‑protein method used for NOPA referee testing.
This test method is an official method for determining nitrogen and/or crude protein content in animal feed and feed ingredients using the combustion method (also known as the Dumas method). It is a rapid alternative to the traditional Kjeldahl method, relying on high-temperature combustion to convert nitrogen compounds into measurable nitrogen gas.
This test method is a classical Kjeldahl-based method for determining crude protein content in animal feed and feed ingredients. It is based on the quantification of total nitrogen in a sample, which is then converted to protein using a standard factor. This method is widely accepted and used in regulatory, quality control, and research settings.
This test method is an enzymatic spectrophotometric method that quantifies D‑mannose by converting sugars through sequential enzyme reactions. It provides a specific, sensitive determination of mannose in plant products and polysaccharide hydrolysates.
This test method is a laboratory procedure used to estimate the digestibility of feedstuffs by simulating animal digestive processes. It is commonly applied in animal nutrition studies to evaluate how well animals can utilize different feed ingredients.
This test method is an official gravimetric procedure for determining calcium carbonate (CaCO₃) content in samples such as minerals, supplements, and food additives. The method involves acid digestion of the sample and measurement of the resulting carbon dioxide to quantify the effective calcium carbonate equivalence.
This test method is a classical gravimetric method used to determine crude fat content in animal feeds through solvent extraction. It is widely applied in feed analysis to quantify the total fat (lipid) content, including triglycerides, phospholipids, and other ether-soluble materials.
This test method is a classical gravimetric method used to determine crude fat content in animal feeds through solvent extraction. It is widely applied in feed analysis to quantify the total fat (lipid) content, including triglycerides, phospholipids, and other hexane-soluble materials.
