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. Productivity of orchard grass (Dactylis glomerata L.) alone and associated with perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.)
ABSTRACT The objective of this research was to evaluate the productive capacity of orchard grass alone and associated with perennial ryegrass and white clover sown at different proportions. Treatments consisted of the following associations and monoculture: 100-00-00, 70-20-10, 50-00-50, 40-40-20, 40-20-40, 20-70-10, 20-40-40, and 00-50-50% of orchard grass,

3. Evaluation of blood metabolites in dairy cows grazing under two pasture allowances and supplemented with corn silage under restricted grazing conditions
ABSTRACT This study was conducted to evaluate the influence of management tools - daily pasture allowance and corn silage supplementation - during periods of forage shortage on the metabolism of dairy cows grazing low-mass pasture in temperate regions. Forty lactating Holstein cows were used during an experimental period of seventy days (April 15 to June 23,

4. Effects of post-grazing forage mass on a beef cattle grazing system on Tanzânia grass pastures
The objective of this study was to evaluate the effect of grazing intensity on herbage accumulation, animal performance, and total system yield on irrigated Tanzania grass pastures under rotational stocking. The experiment was conducted from October 1999 to January 2001, in a complete randomized block design with four replications. Treatments consisted of th

5. Forage yield and nitrogen nutrition dynamics of warm-season native forage genotypes under two shading levels and in full sunlight
The successful achievement of a highly productive understorey pasture in silvopastoral systems depends on the use of well-adapted forage genotypes, showing good agronomic performance and persistence under shading and grazing. In this study, the herbage dry matter yield (DMY) and nitrogen nutrition dynamics were determined in three native warm-season grasses

6. Banco de sementes e sistemas de renovação no pasto de capim-braquiária com integração de culturas agrícolas / Seed bank in renewal of pasture signal grass with crop livestock integration
The experiment was conducted to evaluate the renewal of pasture of Brachiaria decumbens with integration of crops in cropping systems "planting" direct and conventional. The experiment was conducted in pastures of Brachiaria decumbens Stapf. Located on the campus of University Federal of Viçosa, Viçosa, MG. The experiment consisted of five "systems" of gra

7. Development of maize and palisadegrass plants cultivated in intercrop under water deficit
The objective of this work was to evaluate the development and productive traits of palisadegrass single cultivated or intercropped with corn, in addition to corn intercropped with pasture, under water deficit at different development stages of the plants. It was used a complete block experimental design with split plots and three replicates. Periods of wate

8. Tratamento de sementes, densidade e método de semeadura de Brachiaria brizantha no consórcio milho e braquiária / Treatment of seed, density and sowing methods of Brachiaria brizantha intercropping maize and pasture
The integrated crop livestock farming system is an important training and renovation of degraded pastures. However, lack technical information about physiological and sanitary quality of the forage seeds and sowing methods have been suggested as causes of failure in some fields. This work aimed to evaluate the effects of treatment of seeds of Brachiaria briz

9. AVALIAÇÃO DE CEREAIS DE INVERNO DE DUPLO PROPÓSITO NA DEPRESSÃO CENTRAL DO RIO GRANDE DO SUL / EVALUATION OF DOUBLE PURPOSE WINTER CEREALS AT DEPRESSÃO CENTRAL REGION OF RIO GRANDE DO SUL STATE
In the south of Brazil, one of the largest limitations of cattle activity is the forage lack in the autumn and beginning of winter, causing decrease in milk and meat production. One of the alternatives to minimize this problem is the use of double-purpose winter cereals, that they can supply early green forage and still to produce grains. Then, the objective

10. 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

11. Xaraés palisadegrass under grazing: agronomic, morphological, and physiological responses, and adapting the CROPGRO model for predicting forage growth / Capim Xaraés sob pastejo: respostas agronômicas e morfofisiológicas, e adaptação do modelo CROPGRO para a predição de crescimento
On optimization of the animal production systems using models, morphological and physiological aspects of forage plants is required. Moreover, is necessary to understand grazing effects on regrowth, and consequently, on forage mass accumulation. The objective of this research was to evaluate the morphological and physiological responses, and adapting the CRO
