Salmonella [P/N] GDS

This test method is a rapid and reliable procedure for detecting Salmonella spp. in food, feed, and environmental samples. This method is valued for its speed, sensitivity, and specificity in detecting Salmonella in complex samples.

Salmonella Confirmation, Isolation and Speciation

This test method is a comprehensive, standardized procedure for the detection, isolation, confirmation, and speciation of Salmonella in food, feed, and environmental samples.

Sieve Analysis [Feed]

This test method is a standardized method outlining procedures for sieve analysis to determine the particle size distribution of various materials. This test method ensures a consistent and reproducible approach to evaluating particle size.

Sieve Analysis [Wet]

This test method is a procedure for performing sieve analysis on wet feed samples to determine particle size distribution. This method adapts traditional sieve analysis for wet samples, ensuring reliable particle size measurement despite moisture presence.

Staphylococcus Aureus

This test method is a rapid method used for the detection and enumeration of Staphylococcus aureus. This method employs 3M™ Petrifilm™ Staph Express Count Plates, which contain a chromogenic medium that allows presumptive identification of S. aureus based on colony color and morphology.

Relative Feed Quality

Relative Feed Quality (RFQ) is an index used to estimate the overall nutritional value and digestibility of animal feed and forages, taking into consideration factors from crude protein, crude fat, fiber, and ash analyses.

Relative Feed Value

Relative Feed Value (RFV) is an index used to estimate the overall forage quality based on two key fiber components: Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF). It predicts how well a forage will be consumed and digested by ruminant animals, particularly dairy cattle.

Residual Antibiotics

This test method is a multiclass, multiresidue method for the detection and quantification of various antibiotic residues in animal feed.

Residual Hexane [Feed]

This test method is a procedure that uses headspace gas chromatography (GC) to detect and quantify residual hexane in oilseed meals and animal feed ingredients that have undergone solvent extraction.

Resistant Starch

This test method is a standardized enzymatic procedure designed to accurately measure resistant starch (RS) content in foods and feed.
