[Influence of the drying method and the grinding fineness of the sample forage on the determination of nitrogen degradability in the rumen].
The effects of the drying method (freeze-drying, forced-air oven at 60 degrees C for 24 h and conventional oven at 80 degrees C for 48 h) and grinder screen size (0.8 vs 1.5 mm) upon in sacco degradability were compared with 7 forages. Nitrogen degradability was reduced by oven drying even at the lower temperature, but screen size was less important.
