1. CARACTERÍSTICAS ESTRUTURAIS E PRODUTIVAS EM HÍBRIDOS INTRAESPECÍFICOS E INTERESPECÍFICOS DE CAPIM-ELEFANTE
Resumo Objetivou-se avaliar a estrutura e a produção de forragem em híbridos de capim-elefante manejados sob corte. Utilizaram-se como tratamentos 24 clones de capim-elefante provenientes da Embrapa Gado de Leite e o Cameroom como testemunha. Os capins foram cortados rentes ao solo, a cada 60 dias. Os parâmetros avaliados foram: produção e teor de mat�

2. Milk fatty acid composition of unsupplemented dairy cows grazing on a tropical pasture
ABSTRACT This study aimed to evaluate the milk fatty acid (FA) composition of unsupplemented dairy cows grazing on elephantgrass (Pennisetum purpureum Schum. cv. Pioneiro) pastures under three grazing management strategies: pre-grazing height of 120 cm with defoliation intensities of 50 and 70% of the initial height (treatments 120/50 and 120/70) and pre-gra

3. Canopy structure and forage nutritive value of elephantgrass subjected to different stocking rate and N fertilization in the “Mata Seca” ecoregion of Pernambuco
ABSTRACT The objective was to evaluate the effect of three stocking rates (2, 3.9, and 5.8 animal units ha−1) and three fertilization levels (0, 150, and 300 kg N ha−1 yr−1) on herbage mass and nutritive value of elephantgrass (Pennisetum purpureum Schum.) cv. IRI-381. The experiment was conducted from May to August of 2009 and 2010 in Itambé, PE, Bra

4. Nutritional evaluation of elephant-grass silages with different levels of by-products from the cashew juice industry
ABSTRACT This study was conducted to evaluate the intake, apparent digestibility (AD), and degradability in situ of elephant grass (Pennisetum purpureum Schum) silages containing 0, 35.0, 70.0, 105.0, and 140.0 g kg-1 by-product from dried cashew apple (DCBP) (as fed basis). A completely randomized design with four replicates was adopted. For the study of de

5. Elephant grass ensiled with wheat bran compared with corn silage in diets for lactating goats
The objective of this study was to evaluate the use of wheat bran as an additive in elephant-grass silage on intake and digestibility of the nutrients, ingestive behavior, and yield and chemical composition of milk. Eight goats with 45 days of lactation were distributed in a (4 × 4) Latin square design.The treatments consisted of corn silage (CS), elephant-

6. Forage mass and the nutritive value of pastures mixed with forage peanut and red clover
The objective of this research was to estimate three pasture-based systems mixed with elephantgrass + spontaneous growth species, annual ryegrass, for pasture-based system 1; elephantgrass + spontaneous growth species + forage peanut, for pasture-based system 2; and elephantgrass + spontaneous growth species + annual ryegrass + red clover, for pasture-based

7. Capim elefante cultivado em solo ácido com aplicação de gesso com alternativa fitoenergética para o Pólo Gesseiro do Araripe/PE. / Elephantgrass grown in acidic soil with application of gypsum as a phytoenergy alternative to the Gypsum Pole of the Araripe/PE.
O cultivo de capim elefante na Chapada do Araripe em Pernambuco pode ser uma fonte alternativa de energia para calcinação de gipsita. No entanto é uma região com predominância de Latossolos ácidos com elevados teores de Al trocável em subsuperfície, que é tóxico às plantas. A prática mais viável para a redução da toxidez do excesso de Al nessa

8. Allohexaploid pearl millet x elephantgrass population potential for a recurrent selection program.
The objective of this work was to evaluate the potential of allohexaploid pearl millet x elephantgrass (HGL) population for a recurrent selection program through open-pollinated progenies. Seventy-eight progenies, one representative sample of the population, and two commercial cultivars, Pioneiro and Paraíso, were evaluated in a 9x9 triple lattice design, i

9. 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

11. Estimation of genetic parameters among families of clones intra and interspecific elephantgrass hybrids in two forms of genetic evaluation. / Parâmetros genéticos entre híbridos de capim-elefante sob duas formas de avaliação.
The objective of this study was to compare two forms of assessment based on data per se and in the form of genetically stratified selection from genetic parameters in cross intra and inter-specific elephantgrass. The study was conducted in the Itambé Experimental Station, of the Pernambuco Agronomic Institute IPA. For definition of estimated genetic paramet

12. Silagens e fenos em associação à palma forrageira para vacas em lactação e ovinos
This study was conducted to determine the performance of lactating Holstein/zebu cows fed diets based on spineless cactus with different fiber sources, namely sorghum silage, sunflower silage, guandu hay, leucena hay and elephant-grass hay. Five cows (body weight 500 kg and average milk production 12kg) were used in 5 x 5 Latin square design with 12-day peri
