1. Productivity and nutritive value of elephant grass pastures under organic and conventional production systems
Abstract: Elephant grass (EG) (Pennisetum purpureum Schum.) have great importance in tropical and subtropical climates, especially on dairy farms. Normally, EG is established alone under high fertilization levels. EG in organic production system can improve low production costs and environmental issues, are still little known. The aim of this research was to

2. Nutritive value of Tanzania grass for dairy cows under rotational grazing
A nutritional analysis of Tanzania grass (Megathyrsus maximus Jacquin cv. Tanzânia was conducted. Pasture was managed in a rotational grazing system with a 30-day resting period, three days of paddock occupation and two grazing cycles. Ten Holstein × Zebu crossbred cows were kept within a 2-ha area divided into 11 paddocks ha-1. Cows were fed 2 kg of corn

3. Biomass flow in Tifton-85 bermudagrass canopy subjected to different management strategies under rotational grazing with dairy goats
Biomass flow characteristics and forage accumulation were evaluated in Bermudagrass (Tifton 85) pasture managed under intermittent stocking with different management strategies. The management levels utilized were conventional (10 cm residual height and unfertilized), light (20 cm residual height and unfertilized), moderate (20 cm residual height with fertil

4. Performance of nellore cattle under two grazing management systems.
The objective of this study was to evaluate the effects of grazing intensification on birth weight (BW), weaning weight (WW, standartized to 205 days), average daily gain weight (BW), weight (ADG), and gestation length (GL) of calves, cow weight at at weaning (CCW), and BW/CWC (BWR), WW/CWC (WWRC) and WW/CWW (WWRW) ratios. One hundred and sixty eight nellore

5. Braquiaria under irrigation in rotational grazing system and soil physical quality / IrrigaÃÃo em braquiÃria sob pastejo rotacionado e qualidade fÃsica do solo
The seasonality of forage production is a phenomenon of great importance because it is related to the indices of yield and profitability of livestock production. From that results the constant search for new forages and alternatives compatible with the several systems of production as well as the application of new technologies as pasture irrigation and fert

6. AVALIAÇÃO DE DOIS SISTEMAS FORRAGEIROS SOB PASTEJO COM VACAS LEITEIRAS / TWO BASED-PASTURE SYSTEMS EVALUATION UNDER GRAZING WITH DAIRY COWS
The objective of this work was evaluate two pasture-based systems (PS) with elephantgrass (Pennisetum purpureum Schum.), ryegrass (Lolium multiflorum Lam.), and spontaneous growth species varying in one system, the mixture with white clover (Trifolium repens L.) and, in the other system, with forage peanut (Arachis pintoi Kraprov &Gregory), handled under rot

7. Supplementation of BWH cows and ½ BWH ½ Jersey cows kept in tropical pasture with the isopropyl ester of methionine analog (HMBi) / Suplementação de vacas HPB e vacas 1/2 HPB 1/2 Jersey mantidas em pastagem tropical com o éster isopropílico do análogo de metionina (HMBi)
In this trial, was tested the inclusion of isopropyl ester of methionine analogue (HMBi) in the concentrate of BWH cows and ½ BWH ½ Jersey cows kept in pastures of Elephant grass, with the goal of achieving lysine: methionine ratio of 3:1 in metabolizable protein. Variables analyzed were milk production and composition. The forage mass and the nutritional

8. Respostas de bovinos de corte à suplementação energética em pastos de capim-marandu submetidos a intensidades de pastejo rotativo durante o verão / Beef cattle responses to energetic supplementation on Marandu palisadegrass pastures subjected to rotational grazing with different stubble heights during the summer
Adequate grazing management and supplementation practices can increase yield and economical competitiveness of the production system. The purpose of this work was to evaluate the performance of beef cattle on Brachiaria brizantha pastures (Marandu palisadegrass) subjected to rotational grazing managed with different stubble heights (10 vs 15cm), using an ene

9. Viabilidade da utilização de aditivos na ensilagem de capim-braquiarão (Brachiaria brizantha (Hochst ex A. Rich.) Stapf cv. Marandu), manejado sob intensidades de pastejo / Viability on the addictives utilization in braquiarão grass [Brachiaria brizantha (Hochst ex A. Rich.) cv. Marandu] silage process, managed under grazing intensities
Silage is a grassing food conserved by a fermentative process specialy used during scarcity period (dry season). It aims to conserve a high nutritional value with a minimum of losses. In order to assure its produced forage utilization efficiency, it needs to considerate its harvest by animals and machines in a system that uses rotational stocking method. In

10. Sistema silvipastoril e monocultivo de braquiária para recria de novilhas mestiças: disponibilidade e consumo de forragem, ganho de peso e validação do CNCPS.
Four trials were caried out to evaluate growing crossbred holstein x zebu heifers on silvopastoral system (SPS) and signalgrass (Brachiaria decumbens Stapf.) monoculture (SGM). On the first trial were evaluated dry matter avalability and chemical composition and crossbred heifers performance on silvopastoral system and signalgrass monoculture, in rainy seaso

11. Estudo do desempenho animal e produção do capim Tanzânia (Panicum maximum, Jacq.) em um sistema rotacionado de pastejo sob irrigação em três níveis de resíduo pós-pastejo. / Study of the animal performance and herbage production of irrigated tanzania grass (Panicum maximum, Jacq.) in a rotational grazing system under three post-grazing residues levels.
This research was to evaluate effect of the post-grazing pasture mass on morphological characteristics, herbage production and animal performance and productivity from irrigated and rotationally grazed system with Panicum maximum Jacq. cv. Tanzânia. The experimental period was October 30/1999 to January 03/2001 and established at Escola Superior de Agricult
