, apparent substrate degradability of barley grain (ASD), true substrate degradability of barley grain (TSD) and microbial N at t1/2 for two treatments were measured. The amount of produced gas at each time of incubation in each glass serum bottle was taken...

This experiment was conducted to evaluate the effects of different sources of rumen degradable amino acids,

soybean meal versus a commercial source of hydrolyzed cottonseed cake with low molecular weight (Fortid®), ...

fractions improved by treatment with NaOH. In addition, Barnes and Ørskov (1981) indicated that the digestibility of starch increased linearly with NaOH application. Rumen microbial-N yield decreased (from 1.344 to 1.282 mg) by the treatment of barley...
