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. High moisture samples are mixed with celite, or diatomaceous earth, prior to analysis to… Continue reading Crude Fat [Hexane w/ celite]

This test method is a cross-method calculation used to determine the energy content of a sample, utilizing total carbohydrate, crude fat, and crude protein analyses in the “4-9-4 rule,” where there are 4 calories per gram of carbohydrates, 9 calories per gram of fat, and 4 calories per gram of protein in a sample.
This test method is a cross-method calculation used to determine the total carbohydrate content of a sample, utilizing crude protein, crude fat, moisture, and ash analyses to calculate total carbohydrates by difference. The calculation assumes that the remainder after accounting for the protein, fat, moisture, and ash represents carbohydrates, including sugars, starches, and dietary fiber.
This test method is a validated gas chromatography (GC) method for determining cholesterol content in a wide range of foods, including meats, dairy products, and processed items. It involves extraction, saponification, and derivatization steps to isolate cholesterol from the sample matrix, followed by quantification using a GC with a flame ionization detector (FID).
This test method is a classic analytical technique used to determine ammonia nitrogen (NH₃-N) in feed samples. It involves alkalizing the sample to convert ammonium ions to ammonia gas, which is then distilled, captured in an acid solution, and quantified by titration. This method measures the concentration of ammonia as nitrogen and is widely used… Continue reading Ammonium Nitrogen [Feed]
