Dry matter yield and chemical composition of forage grasses harvested from an area degraded by urban solid waste deposits were evaluated. A split-plot scheme in a randomized block design with four replicates was used, with five grasses in the plots and three harvests in the subplots. The mineral content and extraction and heavy metal concentration were evaluated in the second cut, using a randomized block design with five grasses and four replicates. The grasses were Brachiaria decumbens cv. Basilisk, Brachiaria […]

This trial was conducted with the objective of evaluating the nutritive value of three tropical forage species: tanzania grass (Panicum maximum Jacq.), marandu grass (Brachiaria brizantha) and Tifton 85 bermudagrass (Cynodon spp) in two different periods of the year (January-March and April-June) and in three cutting ages (28, 35 and 42 days), based on the chemical composition, protein and carbohydrate fractions, and in vitro digestibility of dry matter (DMD) and organic matter (OMD). Marandu grass, in the period January-March, had […]

Fermentation kinetics and degradation rates of three tropical forage species (Tanzania grass, Marandu grass and Tifton 85 grass) were evaluated by the in vitro gas production technique. The forages were harvested at 28, 35 and 42 days of regrowth during two periods, January-March and April-June. In the January-March period, Marandu grass presented the greatest values of fraction A, potential degradability (PD) and effective degradability for a passage rate of 2 %/hour (ED2). In the April-June period, Marandu and Tanzania grasses […]

The objective was to evaluate the forage yield and chemical composition of millet and Tanzania grass, the first one as a companion crop, in the formation of the Panicum maximum Jacq. cv. Tanzania I pasture, as well as the viability of the use of this practice. The evaluated treatments were four seed mixture combinations based on sowing density of 8 kg/ha of Tanzania grass/millet (08/00; 05/03; 04/04 and 03/05 kg/ha) and three cutting frequencies (three cuttings – 40, 70 and […]
