Extract

Brachiaria spp. pastures, specially B. decumbens, cover an area of 400 thousand ha in Santa Cruz, Bolivia. They comprise the basal diet for ruminants in dual-purpose and small-holder dairy systems of the region (Herrero et al. 1999). Therefore, an important portion of the animal production is conditioned by the amount and quality of these pastures and their intake. Knowledge of pasture intake is crucial for formulating bio-economically feasible feeding systems for ruminants. The objective of this work was to measure intake of Brachiaria spp pastures using alkanes as markers and to quantify pasture intake differences between dry and lactating cows.
