Description
To investigate availability of major elements to animals, N, P, K, Ca and Mg of plant dry matter were partitioned into 4 cell fractions based on enzyme solubility. When the elemental concentration of forage was compared, Dactylis glomerata was higher in K (1.69%), Festuca aru11dinacea in N (2.35%), K (1.68%) and Mg (Q.341 %) and Lolimum perenne in N (2.54%), P (0.224%) and Ca (0.457%). When compared between plant parts, concentrations of all elements.were higher in leaf than in stem, especially P, Ca and Mg. As a result of partitioning, more than 85% of P, K and Mg resided in lhe watersoluble cell fraction. A large proportion of N was detected in the actinase soluble fraction, and a considerable proportion of Ca in the cellulase soluble fraction. The proportion of elements in each cell fraction did 1101 differ significantly between leaf and stem.
