Methane emissions and estimates of ruminal fermentation parameters in beef cattle fed different dietary concentrate levels. Author(s): PEDREIRA, M. dos S.; OLIVEIRA, S. G. de; PRIMAVESI, O. M. A. S. P. R.; LIMA, M. A. de; FRIGHETTO, R. T. S.; BERCHIELLI, T. T. sing sorghum silage, the effect of roughage/concentrate ratios was evaluated on nutrient intake, digestibility, ruminal parameters and methane production by beef cattle. Three treatments (0, 30 and 60... ... Repository: BDPA Publication year: 2013
Methane emissions and estimates of ruminal fermentation parameters in beef cattle fed different dietary concentrate levels. Author(s): PEDREIRA, M. dos S.; OLIVEIRA, S. G. de; PRIMAVESI, O.; LIMA, M. A. de; FRIGHETTO, R. T. S.; BERCHIELLI, T. T. Abstract: Using sorghum silage, the effect of roughage/concentrate ratios was evaluated on nutrient intake, digestibility, ruminal parameters and methane production by beef cattle.

Tucumã oil shifted ruminal fermentation, reducing methane production and altering the microbiome but decreased substrate digestibility within a RUSITEC fed a mixed hay - concentrate diet. Author(s): RAMOS, A. F. O.; TERRY, S. A.; HOLMAN, D. B.; BREVES, G.; PEREIRA, L. G. R.; SILVA, A. G. M.; CHAVES, A. V. Abstract Tucumã oil is sourced from the fruit pulp of the tucumã tree and contains high concentrations of unsaturated fatty acids and carotenoids. Due to these properties it may have the potential to... ... Repository: BDPA Publication year: 2018
