| Um experimento de campo foi efetuado em solo do tipo latosol amarelo textura muito pesada a fim de se estudar o comportamento de uma capineira de capim elefante (P. purpureum Schum) var. Porto Rico, em cinco (5) diferentes alturas de corte (5, 10, 15, 20 e 25 cm do solo). O delineamento usado foi com quatro (4) repetições. Em dois (2) anos de coleta de dados evidenciou-se a maior produtividade e duração de capineira, quando cortada as alturas de 20 e 25 cm do solo. As produções do 1o ano (em todos os tratamentos) foram superiores as do 2o ano e, comparando-se periodos "chuvosos" (7 meses) e "secos" (5 meses) observou-se que no periodo de chuvas obteve-se quase que o dobro de produção do período seco. A proporção de folhas sobre colmos e altura media das... |

| This study characterized seven Pennisetum purpureum varieties, namely v. Anão, Bajra, Cameroon, Guaçu, Roxo, Taiwan A-144 and Uruckwami, through biochemical analyses, including protein, glucose and fructose contents, and polyacrylamide gel electrophoresis using the esterase system, by sampling 30, 60, 90, 120 and 150 day-old leaves. The number of nodes per stem and the percentage of bud emergence were also recorded. Variety Taiwan A-144 presented the highest number of nodes per stem and percentage of emerging buds. Protein concentration decreased gradually after 60 days for all varieties, except for Anão. Variety Guaçu presented the highest level of glucose in 90 day-old plants, whereas Cameroon presented the highest levels at 120 and 150 days. The... |

| The objective of this work was to evaluate the effects of three levels of concentrate (2.0, 4.0 and 6.0 kg/cow/day) and two levels of crude protein (CP) (14 and 16% total dietary dry matter), in comparison to mineral mixture (control) on the intake, apparent digestibility, milk composition and yield and on feed efficiency and use of concentrates of cows grazing elephant grass (Pennisetum purpureum, Schum) in the rainy season. Twenty-one milking Gyr cows with average body weight of 426 kg and yield of 13.0 kg of milk/cow/day at 55 days of lactation were distributed in randomized blocks design, with seven diets (treatments) in a 3 × 2 + 1 factorial arrangement and three replications, in a period of 84 days. Forage dry matter intake was not influenced by the... |

| Cytogenetic studies were carried out on five accesses of interspecific hybrids of Pennisetum purpureum and Pennisetum glaucum and their parentals, which are part of the Forage Germplasm Bank of the "Centro Nacional de Pesquisa de Gado de Leite" of EMBRAPA, Brazil. The mitotic cytogenetic analysis, performed using stain by Schiff reactive, confirmed the chromosome number of 2n = 14, 28 and 21 for the accesses of P. glaucum, P. purpureum and their hybrids, respectively. For each access, descriptions of the chromosome complement and idiograms are presented which allowed to establish the karyotypic relationships between the hybrids and their parentals. Based on the total chromosomal length data it was possible to establish the karyotype classification of the... |

| No estado do Acre, a cobertura vegetal predominante é a floresta tropical úmida, com elevada diversidade de espécies por hectare. Neste áreas, a principal atividade econômica, no último século, tem sido o extrativismo do látex da seringueira (Hevea brasiliense) e a coleta da castanha-do-brasil (Bertholletia excelsa). Entretanto, nos últimos 30 anos, a desestruturação do sistema extrativo da borracha nos seringais nativos, a criação de projetos de colonização e a implantação e expansão da atividade pecuária transformaram a economia do setor primário do Acre. Este trabalho objetivou avaliar a produtividade e composição química da forragem de capim elefante associado às leguminosas arbóreas nativas bordão-de-velho (Samanea sp.) e timbaúba (Enterolobium... |

| The Cornel Net Carbohydrate and Protein System model version 5.0 was assessed as for its prediction of dry matter intake and milk production of grazing lactating Holstein × Zebu cows. Eight lactating cows grazing elephant grass (Pennisetum purpureum, Schum., cv. Napier) were used in two experiments of 30 days each. The experimental design was of randomized blocks (subplots). Dry matter intake was estimated using the chromium oxide and in vitro dry matter digestibility techniques. The estimated dry matter intake was compared with the values predicted by the model. Extrusa samples of the elephant grass pasture were obtained from a cow with esophageal fistula during nine days in each experimental period. Carbohydrate and nitrogenous fractions were analyzed... |

| ABSTRACT We aimed to evaluate the efficiency of six different horizontal subsurface flow constructed wetlands (HSSF-CWs), with different substrates (gravel and crushed PET bottles), which also varied in relation to the presence and arrangement of plant species (elephant grass and Tifton 85 bermudagrass) in the removal of pollutants from a bulk milk cooling tank (MTWW). Each bed was fed at a flow rate of 0.18 m3 d-1 and average organic load rate (OLR) of 318 kg ha-1 d-1 of BOD5, with hydraulic detention time (HRT) of 1.84 days in the gravel-filled HSSF-CWs (CWS-G) and 2.97 days in the PET-filled HSSF-CWs (CWs-P). The CWs-P were as efficient as the CWs-G in the removal of BOD5, COD, Total-P, and K-Total, being in some cases even more effective (turbidity,... |

| Structural characteristics (total in marked tillers of leaves (NFT), expanded leaves (NCE), green leaves (NFV) and dead leaves (NFS) and number of tillers per plant (NPP)) and morphogenic variables (tillering (TApPP) and rates of total leaf (TApFT), expanded leaf (TApFE) and live leaf (TApFV) appearance) were evaluated in four elephantgrass genotypes (Napier, Cameroon and Pioneiro cultivars and clone CNPGL 91 F27 05). Greenhouse evaluations were carried out every three days, from the 3rd to the 60th day after standardization cutting, according to a completely randomized block design under a factorial treatment scheme (four genotypes and 21 measurement days). The NFT and NCE of the CNPGL 91 F27 05 and Pioneiro genotypes were larger than those of Cameroon... |
