| The objective of this work was to evaluate the dry matter production of elephant grass (Pennisetum purpureum) genotypes, managed under intermittent stocking. A completely randomized design was used, with two genotypes and three replicates. The treatments consisted of factorial combinations (2x2x2) of genotypes ('BRS Kurumi' and the clone CNPGL 00‑1‑3), two light interception levels (LI) at the onset of grazing (90 and 95%), and two post‑grazing canopy heights (30 and 50 cm). A total of 24 Holstein x Zebu crossbred heifers were used. The stocking density varied in order to finish the grazing periods in two days. The interval between the defoliation, based on 95% LI, resulted in a higher leaf mass per grazing cycle. The post‑grazing height of 30 cm did not... |

| ABSTRACT The aim of this research was to evaluate elephant grass under an organic and a conventional system. Under the organic system, species with complementary growth periods were combined; elephant grass was planted in rows 3.0 m apart and ryegrass was sown between the rows of elephant grass during the winter period, with spontaneous species being allowed to develop during the summer period. For the conventional production, two types of pasture were studied: one using the same strategy as for the organic production, and the other with a monocrop of elephant grass. Under the conventional and organic systems, 120 kg of N ha-1 were applied as chemical and organic fertiliser (cattle manure and pig slurry) respectively. Holstein cows were used in the... |

| Grazing management strategies affect not only herbage accumulation but also the efficiency of grazing. This study aimed to evaluate herbage accumulation (leaf, stem and dead material), grazing efficiency and losses of mulato grass (a Brachiaria ruziziensis × Brachiaria brizantha cv. Marandu hybrid) subjected to strategies of rotational stocking management. Treatments consisted of combinations between two post-grazing heights (15 and 20 cm) and two pre-grazing conditions (95 % and maximum canopy light interception (LI)) assigned to experimental units (1200-m² paddocks) according to a 2 × 2 factorial arrangement and a randomized complete block design, with four replications. The experiment was carried out from Jan 2008 to Mar 2009. Season of the year... |
