B. de  aPressurized system and microwave-assisted extraction for rapid analysis of fiber in animal feedstuffs.h[electronic resource]  c2008  aA pressurized system under microwave radiation and filter bags to contain the samples was proposed as an alternative to Neutral Detergent Fiber (NDF) determination in animal feed. After optimization by a 23 factorial design, the procedure was applied to nine forage and cereal bran with different amounts of starch (supplied by proficiency testing at various nutrition laboratories). Recoveries from 93 to 110% (0.7 to 7.4 RSD) were obtained. The proposed system allows the NDF simultaneous extraction from 18 samples, increasing the samples throughput from 6 or 40 day?1 to approximately 280 day?1, with low consumption of energy and reagents, producing low amounts of residue.  aneutral detergent fiber  aFeed analysis  aMicrowave assisted extraction  aPressurized1 aMENEZES, E.
