Rovabio® always increases degradability despite variability

The effect of Rovabio® on corn and wheat DDGS was evaluated in vitro by testing the degradability of the dry matter of 13 corn DDGS and 23 wheat DDGS samples from different qualities and origin. The degradability of the control samples was quite variable, ranging from 10 to 49% with an average of 24.5 % for corn DDGS and ranging from 31 to 58% with an average of 41.3% for wheat DDGS. The addition of Rovabio® Excel LC increased the degradability of all samples, with an average of 31.2%, i.e. 6.8 points or 32% relative improvement for corn DDGS and with an average of 50.9% i.e. 9.6 points or 23% relative improvement for wheat DDGS, demonstrating the potential of Rovabio® Excel to work on this type of substrate. The methodology is an adaptation of the method developed by McNiven et al.,2002 using and measuring dry matter degradability. Rovabio® always led to improved degradability because it is a combination of 19 enzyme activities.
