Chemical composition
DM was determined by oven drying the milled samples to a constant weight at 1050C for 8 hours. Crude protein was determined as Kjadhal nitrogen x 6.25. Ether extracts and ash were determined according to (AOAC 1995) method. Neutral detergent fibre (NDF), Acid detergent fibre (ADF) and Acid detergent lignin (ADL) was determined using the method described by Van Soest et al (1991).Hemicellulose was calculated as the difference between NDF and ADF while cellulose is the difference between ADF and ADL.
Statistical analysis
Data obtained were subjected to analysis of variance (ANOVA) and mean separation was by Duncan multiple range tests using Statistical Analysis System (SAS) 1999 package.
