The effect of mild NaOH treatments on sugarcane cellulosic wastes (bagasse, pith, and straw) to increase their biological degradability has been studied. At a level of 8% NaOH (on a dry matter basis) 60% digestibility measured by the in vitro technique was achieved for all materials tested. Indirect methods to predict the digestibility of treated materials such as the bacterial degradability, enzymatic degradability, hot-water solubility, and chemical oxygen demand were tried as alternative methods to the rumen fluid technique. High correlation coefficients for all materials were obtained with all alternative techniques. The minimal r value was 0.96 while the highest was 0.99. An important reduction of time and reagents is achieved by the utilization of the solubility and chemical oxygen demand tests. (Refs. 8).
