N-Alkanes method to estimate dry matter intake on tropical grasses. Author(s): GENRO, T. C. M.; GENRO NETO, J. S.; CÔRREA, A. C. J.; LACA, E. A. This trial was conducted to define which alkane (C31 and C33) must be paired with the external marker (C32) to estimate dry matter intake (DMI) of steers grazing three tropical grasses: Brachiaria bri... ... Repository: BDPA Publication year: 2011
Bayesian hierarchical models to improve estimation of diet composition by alkane profiles. Author(s): LACA, E. A.; GENRO, T. C. M.; GENRO NETO, J. S. Alkane profiles in forage and feces are used to determine diet composition, essentially by inverting a linear mixing equation. Depending on the number of dietary components, number of alkanes and diff... ... Repository: BDPA Publication year: 2011
Estimating forage intake of lactating dual-purpose cows using chromium oxide and n-alkanes as external markers. Author(s): OLIVEIRA, D. E. de; MEDEIROS, S. R. de; TEDESCHI, L. O.; AROEIRA, L. J. M.; SILVA, S. C. da The n-alkanes have been used to estimate forage dry matter intake, digestibility and the diet composition in grazing animals. The objective this study was to compare chromium oxide and n-alkanes techn... ... Repository: BDPA Publication year: 2007
Validation of the n-alkane technique to estimate dry matter intake in sheep. Author(s): ROSSETTO, J.; GENRO, T. C. M.; CARVALHO, P. C. F.; REFFATTI, M. V.; BREMM, C. Repository: BDPA Publication year: 2017
Fecal n-alkanes variation in lactating dairy cows grazing a tropical pasture (Cynodon nlemfüensis vanderyst var. nlemfüensis). Author(s): OLIVEIRA, D. E.; MEDEIROS, S. R. de Repository: BDPA Publication year: 2015
Effects of supplementation frequency on the ruminal fermentation and enteric methane production of beef cattle grazing in tropical pastures. Author(s): CANESIN, R. C.; BERCHIELLI, T. T.; MESSANA, J. D.; BALDI, F.; PIRES, A. V.; FRIGHETTO, R. T. S.; FIORENTINI, G.; REIS, R. A. Abstract: The objective of this study was to evaluate the characteristics of ruminal fermentation and enteric methane production in beef cattle subjected to different supplementation frequencies while... ...

Dry matter intake from beef cattle grazing natural grassland with different intensification levels. Author(s): GENRO, T. C. M.; FARIA, B. M.; SILVEIRA, M. C. T. da; ROSSETO, J.; SANTOS, A. S.; BERNDT, A.; BAYER, C.; SAVIAN, J.; CARVALHO, P. C. F. Estimating dry matter intake from grazing animals remains a challenge. Among the indicators currently used, n-alkanes have been shown to be a good alternative, especially in heterogeneous environments... ... Repository: BDPA Publication year: 2016
Biomarker analysis in soils of the Amazon rainforest after vegetation fire. Author(s): COSTA, J. B. da; DICK, D. P.; LIMA, M. O.; LARA, L. Z.; PERALBA, M. do C.; COSTA, F. de S. The objective of this study was to determine the origin of organic matter incorporated in Amazon forest soils subjected to vegetation fire by analyzing the aliphatic biomarkers (n-alkanes) present in... ...

Herbage production and grazing losses in Panicum maximum cv. Mombaça under four grazing managements. Author(s): CARNEVALLI, R. A.; SILVA, S. C. da; BUENO, A. A. O.; UEBELE, M. C.; BUENO, F. O.; HODGSON, J.; SILVA, G. N.; MORAIS, J. P. G. The n-alkanes have been used to estimate forage dry matter intake, digestibility and the diet composition in grazing animals. The objective this study was to compare chromium oxide and nalkanes techni... ... Repository: BDPA Publication year: 2006
Emission of VOC and GHG by bioremediation of soil contaminated with diesel. Author(s): FRANCO, M. G.; CORRÊA, S. M.; MARQUES, M.; PEREZ, D. V. Bioremediation processes have been credited fo r reducing high levels of organic contaminants from soils. However, during bioremediation of dies el contaminated soils, for instance, diesel is converte... ... Repository: BDPA Publication year: 2012
