abstract
An experiment was conducted to study the nutrient composition and in-vitro nutrient digestibility of Saura (Streblus asper Lour.) fodder tree leaves of Assam. The nutrient composition and in-vitro nutrient digestibility were studied in two different seasons i.e. summer and winter and at two different regions i.e. plains and hills. The average CP content of Saura (Streblus asper Lour.) leaves in plain region was 16.85% and in hill region was 16.58% irrespective of the season and in summer it was 17.13% and 16.30% in winter irrespective of the region. The average IVDMD of Saura (Streblus asper Lour.) tree leaves was found to be 68.44% and 61.58% in plains and hills region respectively irrespective of the season which was significantly higher in the plain region whereas the IVDMD was 66.19% and 63.83% respectively for summer and winter. The average IVOMD was found to be 74.26% and 73.12% in plains and hills respectively irrespective of the season whereas it was 74.23% and 73.15% in summer and winter respectively irrespective of the region. From the chemical composition and nutrient digestibility, it was observed Saura (Streblus asper Lour.) fodder leaves have both nutritional value and can be fed to the livestock during fodder shortage and scarcity period.
