title: [The feed value of pasto estrella (Cynodon nlemfuensis) of Panamanian origin in Cuba. 2. Relation of easily determined parameters of feed value and the digestibility of organic substances].
abstract: The relations between nutrient content and the digestibility of the organic matter (DOM) was to be studied in the tropical grass pasto estrella p. (Cynodon nlemfuensis) in order to draw conclusions as to the causes of changes of the feed value and to estimate DOM with the help of easily determinable parameters. Comparative studies of cellulase solubility from the organic matter also served this purpose. Grass samples from three continuous digestibility studies were used as test material. There is a strong negative dependence of DOM on the content of cell wall substances (crude fibre, lignin) which is characterized by regression coefficients (-1.68, -4.00). Due to a low average protein content changes in the crude protein content had a particularly positive influence on DOM. Regression equations are recommended for the estimation of DOM, the content of metabolizable energy and NEFUcattle from the content of crude fibre, lignin, crude protein and cellulase solubility of the organic matter (biostatistical residual dispersion = 2.1-2.3% DOM; 0.35-0.36 MJ metabolizable energy or 0.2-0.21 MJ NEFUcattle).
