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... ...

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
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
Dry matter intake, methane emissions and performance by beef heifers grazing temperate pastures in two integrated croplivestock systems. Author(s): PONTES, L. da S.; GENRO, T. C. M. Dry matter intake (DMI) is a key driver of animal production in pasture-based systems. Sward structure is related to DMI. When forage plants are cultivated under trees, they may change their morpholog... ... Repository: BDPA Publication year: 2021
Burning of tropical brazilian rainforest of sandy soil: does it affect soil organic matter? Author(s): LIMA, M. O.; DICK, D. P.; COSTA, F. de S.; COSTA, J. B. da; LARA, L. Z.; PERALBA, M. do C. This study aimed to investigate the impact of vegetation burning on the content and chemical composition of soil organic matter (SOM) along a profile of a sandy Acrisol in Southwestern Amazon, Brazil,... ...
