A deficiency of each essential macrominerals or microminerals in animals results in abnormalities that can only be corrected by supplementation of the deficient minerals. Forages provide an important source of minerals for ruminants. In some instances, forages may provide adequate quantities of all essential minerals required by ruminants. In other situations, forages are deficient in one or more minerals and supplementation is required for optimal animal performances. The association of certain minerals with fiber or other insoluble plant components could decrease the rate and extent of mineral release from forages in the gastrointestinal tract. Objectives of this study was to determine changes in minerals concentration in dry matter of red clover -- K 39 and K 32 cultivars with advancing plant growth and development in the first cut, and to measure the amount of minerals associated with the cell wall components. Three stages of red clover cultivars -- mid bud stage, early bloom and mid bloom, were examined in the first cut. The experiment was established as a completely randomized block design in three replications. The concentration of Fe, Zn, Cu and Mn were measured by atomic absorbance spectrophotometry. Analyses of variances revealed significant differences between stages of plant development for investigated minerals. The highest proportion of Cu and Mn were associated with cell wall components of red clover.enCC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/cell wall componetsmicroelementsred cloverconferenceObject
