The study was designed to evaluate the chemical composition and comprehensive strength of urea molasses blocks using different binding agents, fibre source and drying methods. Different blocks were produced and dried for seven days under shade and sun. Dry matter content was higher 92.7% in sun dried rice bran with cement (SRWC) and 92.6% in sun dried wheat offal with cement (SWWC) with the least 88.0% in shade dried wheat offal with cement (SHWWC). Organic matter was higher 90.1% in SRWC and lowest 82.7% in shade dried wheat offal with termite mould (SHWWM). Sundried method reduced crude protein up to 46.92%. Ash content was higher 5.98% in SHWWM and lowest 2.68% in SRWC. Neutral detergent and acid detergent fibre (NDF and ADF) were higher 25.6% and 16.6% in SRWC and least 20.2% and 12.1%) SHWWM respectively. In comprehensive strength, sun dried rice bran with termite mould and SRWC had the highest strength compared to SHWWM and SHWWC. Sun drying method denature protein and significantly increased comprehensive strength. Blocks with rice bran contain high NDF and ADF. Using any of the binding agents, Shade drying method may be recommended as the best drying method.
