ABSTRACT – The objective of this work was to evaluate the effect of a commercial bacterial inoculant containing Lactobacillus plantarum, Streptococcus faecium and Pediococcus acidactili on the quality and dry matter (DM) loss of sorghum (Sorghum bicolor L. Moench) during the ensilage process. The treatments were constituted of two types dual propose sorghum silage harvested at the dough stage: without (control) and with inoculant; three positions in each silo (front, middle and back regions) corresponding to three periods of collection […]

ABSTRACT – With the objective to increase the germoplasm availability for forage production, 215 accessions of the genus Paspalum collected in different regions and introduced at the Embrapa Southeast – Cattle Research Center, located at the central region of the São Paulo state. These accessions were evaluated and selected based on their yields in the first year, of dry matter from the vegetative development throughout the year and during the period of high and low rain preciptation. The accesses were […]

ABSTRACT – The objective of the experiment was to evaluate the dynamics, forage yield and quality of the mixtures of oat + ryegrass (MOR), triticale + ryegrass (MTR), rye + ryegrass (MRR) in continuous grazing. Beef heifers with seven months of age and initial 140 kg LW were used. The sowing was broadcast at 04/12/96, using 85 kg/ha of oat, 170 kg/ha of triticale, 140 kg/ha of rye and 30 kg/ha of ryegrass, in the respective mixtures. The area was […]

ABSTRACT – A field experiment was conducted to determine the effect of acid soil correction, on the control of the sapé (Imperata brasiliensis), a grass type weed of pasture. A molasses grass (Melinis minutiflora) pasture in a red-yellow latosol, having a high proportion of “sapé” was used. Treatments consisted of five levels of dolomite limestone (0, 1, 2, 4 and 6 t/ha) incorporated by hand using a garden tool to the top 20 cm of soil following a mechanical tillage […]

ABSTRACT – The degree of a simple linear correlation among the in vitro dry matter disappearance (IVDMD) and chemical composition of the leaf blades and sheath, and stems, sampled from the top and bottom tillers of dwarf elefantgrass (Pennisetum purpureum, Schumach cv. Mott, setariagrass (Setaria anceps, Stapf ex Massey cv. Kazungula) and jaraguagrass (Hyparrhenia rufa, Nees Stapf), was evaluated. A gradient pattern was observed for IVDMD, crude protein (CP) and cell wall (NDF) along the tiller profiles and difference among […]

The objective of this work was to verify the effect of ammoniation on the contents of crude protein (CP), nitrogen retention (NR), dry matter (DM) content, preservation, cell wall constituents and in vitro dry matter disappearance (IVDMD) of cracked corn with high moisture (25%). Four levels of anhydrous ammonia (0, 1, 2 and 3%) and five aeration periods (0, 7, 14 21, and 28 days) were studied using a completely randomized design, in a split plot design. The contents of […]

This trial was carried out, from October 1993 until June 1995, to evaluate the chemical composition and dry matter digestibility of dwarf elephantgrass at plant heights of 80 and 120 cm under five nitrogen rates. The experimental design was completely randomized with a split split plot arrangement, with four replicates, where the clipping factors, and nitrogen doses (0, 25, 50, 100kg/ha•clipping, in the first year, and 0, 75 and 100 kg ha•clipping, in the second year, and plant heights (80 and […]

Sugarcane bagasse with 55% of dry matter (DM) was treated with five levels of urea (0, 2.5, 5, 7.5, and 10%) and 5% ground whole soybean as a source of urease both, on a DM basis. The material was stored in plastic bags for 97 days (8 kg/ 50 L plastic bag), and after plastic bag opening, samples were collected at three aeration period (2, 9, and 16 days). A completely randomized design with three replicates was used. There was […]

The objectives of this work were to estimate the dry matter intake by animals grazing three cultivars of Panicum maximum, and to relate it to live weight gain, grazing time (GT) and some structural and chemical characteristics of the pastures. The experimental design was the randomized block with three treatments and three replicates. The dry matter voluntary intake (DMVI) was estimated in four periods (May, September, November and February). Fecal output was measured using chromic oxide as an external marker. […]

Annual cold season forage species, Avena strigosa Schreb cv. IAPAR-61 Ibiporã, Lolium multiflorum Lam cv. Comum, Lotus subbiflorus Lag cv. El Rincón, Avena sativa L. cv. UPF-16, Trifolium subterraneum L. cv. Woogenellup, Trifolium resupinatum L. var. resupinatum cv. Kyambro, Secale cereale L. cv. BR-1, Trifolium vesiculosum Savi cv. EMBRAPA-28 Santa Tecla and Vicia angustifolia L. were evaluated using a randomized block design with three replicates, from 1994 to 1996, at Terras Baixas Experimental Station, EMBRAPA – Temperate Climate Research Center, […]
