Session 8: Improved Grassland Machanization and Cropping Systems Including a Section Dealing with Improved Research Techniques for Laboratory and Field Evaluation of Forages
Publication Date

Description
Reliable, inexpensive and rapid methods of determing in vitro dry matter digestibility (DMD) are necessary to evalute animal production potential of a given herbage. The objective of this research was to determine the relationship between DMD measured by a procedure using a potent cellulase solution (from Trichoderma reese1) and by a procedure using rumen liquor. Herbage from 22 species was assayed. Correlations between in vitro DMD determined by the cellulase procedure and rumen liquor procedure ranged from 0.24 to 0.99. Most correlations were highly significant and greater than 0.95. Regression coefficients ranged from 0.26 to 1.43. The cellulase procedure was an excellent predictor of in vitro DMD for herbage from a wide range of species.
