1. Beef cattle performance on signal grass pastures deferred and fertilized with nitrogen
RESUMO Foi avaliado o efeito de quatro doses de nitrogênio (0, 40, 80 e 120kg N ha -1 ), aplicadas antes do diferimento, sobre o desempenho de bovinos e as características estruturais de Urochloa decumbens (capim-braquiária), de janeiro a outubro de 2012 e de janeiro a setembro de 2013. Um delineamento de blocos ao acaso foi utilizado em arranjo de medid

2. Effects of Glyphosate on Eucalyptus After its Application on Brachiaria (Signal) Grass
ABSTRACT The objective of this article was to evaluate the effects of glyphosate on the initial development of eucalyptus (Eucalyptus urograndis) after its application on brachiaria (signal) grass plants (Brachiaria decumbens). The experiment was conducted in a greenhouse in a completely randomized design. Glyphosate, aminomethylphosphonic acid (AMPA) and sh

3. Nutritional performance of cattle grazing on low-quality tropical forage supplemented with nitrogenous compounds and/or starch
The objective of this work was to evaluate the effects of protein and/or starch supplementation on the nutritional performance of cattle grazing on low-quality tropical forage. Five crossbred steers (Holstein × Gyr) with an average body weight (BW) of 397 kg that were fitted with ruminal and abomasal cannulae were used. The animals were kept in individual s

4. Evaluation of models for prediction of the energy value of diets for growing cattle from the chemical composition of feeds
The objective of this study was to estimate and evaluate the contents of apparently digestible fractions of crude protein, ether extract and non-fibrous carbohydrates, the digestible fraction of the neutral detergent fiber and the content of total digestible nutrients (TDN) from the chemical composition of feeds in growing cattle fed different diets. Fourtee

5. 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

6. Evaluation of ruminal degradation profiles of forages using bags made from different textiles
The objective of this study was to evaluate the in situ degradation profiles of dry matter (DM) and neutral detergent fiber (NDF) of different forages using nylon (50 µm), F57 (Ankom®) and non-woven textile (NWT - 100 g/m²) bags. Eight forage samples were used: sugarcane, corn silage, elephant grass cut at 50 and 250 days of regrowth, corn straw, signal g

7. Valor nutricional de híbridos de sorgo com capim-sudão em comparação ao de outros volumosos utilizados no período de baixa disponibilidade das pastagens.
The objective of this study was to compare the nutritional value of sorghum-sudangrass hybrids to roughages collected in differed pastures, reserves of forage for using in cutting regime and conserved forage as hays or silages. The sorghum-sudangrass hybrids AG2501C and BRS800 showed similar bromatological composition and in vitro dry matter digestibility (I

8. NEMATÓIDES ENTOMOPATOGÊNICOS COMO CONTROLADORES BIOLÓGICOS DE CIGARRINHAS DO GÊNERO Mahanarva (HEMIPTERA: CERCOPIDAE)
The spittlebugs belonging to the genus Mahanarva cause damage to the Poaceae family cultures, like signal grass, elephant grass and sugar cane, by the sap feeding on roots (immature phase) and leaves (adult phase). With the increase demand to reduce use of chemical insecticides for the insect pests control, comes the need to develop new control methods. In t

9. Doses de nitrogênio e de enxofre para a recuperação de pastagem com capim-braquiária: atributos de parte aérea, raízes e fertilidade do solo / Nitrogen and sulfur rates for a Signal grass pasture recovery: forage aboveground and roots, and soil fertility attributes
Fertilizer application has been essential to pastures establishment, maintenance and recovery, whereas sulfur supply may be inadequate for grasses receiving high nitrogen rates. The objectives were to study the effects of combined nitrogen and sulfur rates in a degrading Signal grass (Brachiaria decumbens) pasture, by evaluating productive, morphological, ph

10. Nitrogênio e enxofre para gramínea forrageira: atributos do solo e aspectos metabólicos, nutricionais e produtivos da planta / Nitrogen and sulphur for graminaceous forage plants: soil attributes and metabolic, nutritional and productive aspects of plants
The nitrogen and sulphur availability in soil might influence plant growth, affecting the vegetal production. The objectives of this work were: a) to assess fertilization with nitrogen and sulphur rates on yield of Brachiaria brizantha cv. Marandu (Marandu palisadegrass) under establishment in a soil supporting degrading pasture of Brachiaria decumbens (Sign

11. In vitro degradation dynamics of neutral detergent fiber of signal grass according to supplementation with different levels and sources of nitrogenous compounds / Dinâmica de degradação in vitro da fibra em detergente neutro de capim-braquiária em função de suplementação com diferentes níveis e fontes de compostos nitrogenados
Efetuaram-se dois experimentos in vitro com o objetivo de avaliar a dinâmica de degradação in vitro da fibra em detergente neutro (FDN) de forragem tropical de alta e baixa qualidade em função da suplementação com diferentes níveis e fontes de compostos nitrogenados. Nos dois experimentos utilizou-se como fonte de proteína verdadeira a caseína e de

12. Microbial populations and fermentation profile in tropical grass silages and performance of beef cattle fed diets containing mombaça grass silages / Populações microbianas e perfil fermentativo em silagens de capins tropicais e desempenho de bovinos de corte alimentados com dietas contendo silagens de capim-mombaça
This study consisted of five experiments. The first evaluated the microbial populations, fermentation profile and chemical composition of silages of signal grass at different regrowth ages (30, 40, 50, 60 and 70 days) in six fermentation periods (1, 3, 7, 14, 28 and 56 days). There was increase in lactic acid bacteria (LAB) and decrease in enterobacteria (EN
