It involves incubation first with rumen liquor and then with acid pepsin. Using 146 samples of grass, clover and lucerne of known <jats:italic>in vivo</jats:italic> digestibility (<jats:italic>Y</jats:italic>), the regression equation <jats:italic>Y</jats:italic>= 0·99 <jats:italic>X–</jats:italic> 1·01 (S.E. ± 2·31) has been calculated, where <jats:italic>X</jats:italic>=<jats:italic>in vitro</jats:italic> dry‐matter digestibility. This technique has been used for the study of the digestibilities of plant breeder's material, of the leaf and stem fractions of herbage and of herbage consumed by animals.</jats:p>","journal":"Grass and Forage Science","year":1963,"id":8092,"datarank":26.832400235472363,"base_score":8.788288460263619,"endowment":8.788288460263619,"self_citation_contribution":1.318243269039543,"citation_network_contribution":25.51415696643282,"self_endowment_contribution":1.318243269039543,"citer_contribution":25.51415696643282,"corpus_percentile":96.4,"corpus_rank":2257,"citation_count":6556,"citer_count":199,"citers_with_citation_signal":199,"citers_with_endowment":199,"datacite_reuse_total":0,"is_dataset":false,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"1963-06-01","authors":[{"id":72061,"name":"R.
