On the Estimation of Crude Fibre in Fodders and Concentrates

Abstract

It is apparent from the study that the crude fibre content of a fodder may be affected significantly by its state of subdivision and by the procedure used for filtering the acid digest.Any departure from the standard procedure described in the Fertilizers and Feeding-Stuffs Regulations for filtering the acid digest, such as that of filtering through cloth, would seem permissible only if the retentiveness of that cloth is known not to differ significantly from that of filter paper. The United States filter cloth, and one of the Terylenes (A) would conform to this requirement; the linen most certainly would not.
