Determination of Crude Fiber Content in Feeds Using Polyester Mesh Bag Method
摘要
Abstract
This study aimed to explore a rapid method of using polyester mesh bag to determine crude fiber ( CF) content in feeds, and to evaluate the accuracy and precision of this method. The CF contents in 18 kinds of feeds such as soybean meal, wheat bran, rice bran, alfalfa and peanut vine and so on were analyzed using the polyester mesh bag method, traditional method ( GB/T 6434—2006 ) and Ankom bag fiber determinator method. The CF contents in 8 kinds of feeds such as wheat bran, rice bran, peanut vine, swine compound feed, rabbit compound feed, alfalfa, peanut vine and rice hull were analyzed in 10 different laboratories using the polyester mesh bag method for assessing repeatability limit and reproducibility limit of this method. The re?sults showed that there were no significant difference between the polyester mesh bag method and traditional method ( P＞0.05) , indicating that the polyester mesh bag method had higher accuracy. The repeatability varia?bility coefficients of 8 kinds of feeds used in this study, ranged from 1.45% to 3.64%, and the reproducibility variation coefficient was between 1.79% and 5.64%. The repeatability limit was between 0.57% and 1.99%, and the reproducibility limit was between 0.88% and 3.47%, indicating that the polyester mesh bag method had higher precision. In conclusion, the polyester mesh bag method for determining CF contents has the advantages of lower cost, shorter analysis time, higher efficiency and higher accuracy and precision; therefore, this meth?od can determine CF contents of large quantities of samples.[ Chinese Journal of Animal Nutrition, 2019, 31 (6) :2875?2881]关键词
