Ruminal release of minerals from six forage species.

摘要: An in vitro technique and an situ were used to measure release of Ca, Mg, P Zn over time from hand-clipped alfalfa (Medicago sativa L.). Maximal was greater using the technique. 'Florida 77' L.), 'Florigraze' rhizoma peanut (Arachis glabrata Benth.), 'Mott' dwarf elephantgrass (Pennisetum purpureum Schum.), 'Tifton 78' bermudagrass (Cynodon dactylon (L) Pers.), 'Pensacola' bahiagrass (Paspalum notatum Flugge) 'Floralta' limpograss (Hemarthria altissima (Poir.) Stapf Hubbard) examine ruminal P, K, Cu by means Minerals ranked highest lowest for extent immediate maximal rumen. Averaged across forage species, ranking K at 100% 100%, Mg 82% 95%, 71% 84%, 66% 80%, 26% 69% Ca 29% 70%. A large proportion associated with plant cell wall, based on duration incubation needed maximize its fractinal amount slowly released. portion released as well (mean, 43.8%), but less than 24 h. Most probably reside contents. Forages high NDF concentrations can have coefficients their minerals.
