DSD 5.9 | Undegradable NDF clogging your herd?

Despite decades of dedicated research, the rumen still remains a bit of a ‘black box’. This month we feature an article from  Dr. Gonzalo Ferreira and his team at Virginia Tech as they try further define how undegradable fiber impacts the rumen's flow rate, and therefore productivity.

Comprehending the kinetics of degradation will assist in identifying the ideal combination of ingredients to create a profitable ration for your herd.

Could this help you make future planting decisions, as the nation is repairing from several rounds of drought? Does the ‘queen of forages’ belong in your cropping program?
