Protein degradability of silages in the rumen
estimated by NIRS

The feasibility of estimating in situ ruminal protein degradability parameters (A, B, C, ERD) of silages by NIRS was investigated. In situ protein degradability of maize (n=12), whole-crop cereal (n=18) and lucerne (n=24) silages was determined using two ruminally cannulated Holstein heifers. The NIRS measurements were conduced using a 19-flter spectrophotometer, InfraAlyzer 450R, in the range of 1445-2348 nm. Calibration equations based on 5 terms for all (n=54) and for 3 subsets of different kinds of silages were calculated. The NIRS method can be successfully used to estimate the ERD of silages. By using small, homogenous files, the precision of estimation can be increased and the standard error of estimation decreased.
