Description
Annual grass pasture sprayed with glyphosate (180 g a.i./ha) at heading retained higher concentrations of water-soluble carbohydrates anci nitrogen than control pasture during senescence. Consequently, the. i11, vitro digestibility of the sprayed pasture was also higher than that of the control pasture. Merino wethers (18 months old) grazing the sprayed pasture consumed more senescent herbage and gained weight ( 40 g/ head/day) until 60 days after anthesis, whereas those grazing control pastures only maintained their Jive weight. However, in both treatments pasture feeding value declined with time and as a consequence improved aniinal performance was not maintained indefinitely.
