Mixed silages of sugarcane and forage peanut treated with Lactobacillus buchneri
Costa,Douglas Rodrigues da; Ribeiro,Karina Guimarães; Cruz,Gabriel Ferreira de Lima; Silva,Thiago Carvalho da; Cardoso,Lucas LadeiraAbstract There is evidence for the beneficial effects of forage peanut on the nutritive value and fermentation profile of silages; however, its effects on sugarcane silage have not been determined. The objective of the study was to evaluate the chemical composition, fermentation profile, microbial composition, and dry matter recovery (DMR) of sugarcane silage containing various amounts of forage peanut (Arachis...
Accelerated aging for evaluation of vigor in Brachiaria brizantha ‘Xaraés’ seeds
Oliveira,Ariadne Morbeck Santos; Nery,Marcela Carlota; Ribeiro,Karina Guimarães; Rocha,Adriana Souza; Cunha,Priscila TorresAbstract: The aim of this study was to adjust the accelerated aging test to evaluate the physiological potential of seed lots of Brachiaria brizantha ‘Xaraés’, represented by four lots. Seeds were tested by traditional accelerated aging and with saturated NaCl solution in five aging periods: 0, 24, 48, 72 and 96 hours. The profile of the lots was determined by the following measures: moisture content, germinati...
Chemical composition in soybean silages with inoculant and molasses
Rosa,Lilian Oliveira; Pereira,Odilon Gomes; Ribeiro,Karina Guimarães; Valadares Filho,Sebastião de Campos; Cecon,Paulo RobertoAbstract Chemical composition was assessed in soybean silages without any additive (control), with a microbial inoculant (I), with I + molasses (I+M), and with molasses only (M). Soybean plants were harvested at the reproductive 6 (R6) stage and ensiled in 2 kg-capacity PVC laboratory silos. The SIL ALL C4 inoculant produced by Alltech Brazil was used in combination with or without 2.5% molasses added to the na...
Urochloa decumbens grown with different Eucalyptus clones in an integrated crop...
Guimarães,Cíntia Gonçalves; Pereira,Rosana Cristina; Ribeiro,Karina Guimarães; Viana,Maria Celuta Machado; Santos,José Barbosa dosABSTRACT The objective of this study is to evaluate the forage mass, chemical composition, mineral content, and mineral absorption in signal grass (Urochloa decumbens) grown with different eucalypt clones in an integrated crop-livestock-forest (iCLF) system. The split-split-plot scheme included three replicates arranged in a completely randomized block design. The eucalyptus clones GG 100 and I 144 (Eucalyptus ...
MASSA DE FORRAGEM E CARACTERÍSTICAS ESTRUTURAIS E BROMATOLÓGICAS DE CULTIVARES ...
Silva,Janaina de Lima; Ribeiro,Karina Guimarães; Herculano,Bruna Nogueira; Pereira,Odilon Gomes; Pereira,Rosana CristinaResumo Objetivou-se avaliar as características estruturais, a produção de massa seca e a composição bromatológica de cultivares de Brachiaria e Panicum. O estudo foi conduzido em casa-de-vegetação, em delineamento em blocos casualizados, com cinco tratamentos, sendo três cultivares de Brachiaria (B. decumbens cv. Basilisk, B. brizantha cv. Marandu e cv. Xaraés) e dois cultivares de Panicum (P. maximum cv. Momba...
Forage mass and morphological composition of Marandu palisade grass pasture und...
Anjos,Albert José dos; Gomide,Carlos Augusto de Miranda; Ribeiro,Karina Guimarães; Madeiro,Afrânio Silva; Morenz,Mirton José FrotaABSTRACT An evaluation of productive potential is not the only factor used to determine grazing management efficiency; it is also necessary to know the structural characteristics of the canopy. The objective of this study was to evaluate the effects of two management styles on Marandu palisade grass pastures under rotational stocking with respect to the herbage mass, morphological composition, and structural ch...
Leaf area and epicuticular wax content of Sida spp
Cunha,Viviane Cristina da; Santos,José Barbosa dos; Guimarães,Cintia Gonçalves; Ribeiro,Karina Guimarães; Miranda,Roqueline Rodrigues Silva deMorpho-physiological characteristics and chemical composition are directly related to superior competitive ability of crops. This study intended to make a comparative analysis of dry matter production, leaf area and amount of epicuticular wax of three species of Sida spp: S. urens L., S. rhombifolia L. and S. spinosa L. Plants were collected at three growth stages: V1: stage described as up to 10 fully expanded...
Physical properties of a Red-Yellow Latosol and productivity of a signalgrass p...
Souza,Igor Alexandre de; Ribeiro,Karina Guimarães; Rocha,Wellington Willian; Pereira,Odilon Gomes; Cecon,Paulo RobertoThe physical properties and fertility of the soil are important factors in the formation and establishment of pasture. Changes in physical properties affect the movement of water, air, nutrients and roots, which, in turn, affect the productivity and longevity of pastures. The objective of this study was to evaluate the physical properties of the soil and the dry matter yield of a pasture with signalgrass cv. Ba...
Forage production of elephant grass under intermittent stocking
Chaves,Carla Silva; Gomide,Carlos Augusto de Miranda; Ribeiro,Karina Guimarães; Paciullo,Domingos Sávio Campos; Ledo,Francisco José da SilvaThe objective of this work was to evaluate the dry matter production of elephant grass (Pennisetum purpureum) genotypes, managed under intermittent stocking. A completely randomized design was used, with two genotypes and three replicates. The treatments consisted of factorial combinations (2x2x2) of genotypes ('BRS Kurumi' and the clone CNPGL 00‑1‑3), two light interception levels (LI) at the onset of grazing ...

Rigueira,João Paulo Sampaio; Pereira,Odilon Gomes; Ribeiro,Karina Guimarães; Mantovani,Hilário Cuquetto; Agarussi,Mariele Cristina NascimentoThe objective of this study was to evaluate the fermentation profile, chemical composition and microbial population and losses in the silages of signalgrass and Mombasa grass fertilized with the following levels of nitrogen (N): 0, 30, 60 and 90 kg/ha. The grasses were harvested at 70 days of regrowth, chopped and then ensiled in laboratory silos that had 20 kg of capacity and a snap-top cover and were fitted w...
