Abstract: The lignin content of 50 samples of five grasses of known in vivo digestibility were determined by the methods of van Soest and Wine,1 and of Edwards2 which utilise the solubility of lignin in potassium permanganate and in HCl-activated trigol, respectively, and of Christian3 in which the sample is refluxed with acid detergent after treatment with 72% sulphuric acid without any preliminary extraction. Mean lignin values for the three methods were 4.97, 5.57 and 7.24 and the errors in predicting dry matter digestibility were ±3.9, ±4.5 and ±2.4, respectively. When compared with the error of ±2.1 previously obtained on the same samples with the in vitro technique of Tilley and Terry4 only the method of Christian3 appeared favourable. |
