RESULTADOS
Conclusões
1. A técnica do gás traçador SF6 para medir CH4 ruminal pode ser
utilizada nas condições brasileiras de campo.
2. A emissão de CH4 por bovinos sem restrição de alimentos baseados
em forrageiras tropicais é superior à de bovinos alimentados com
forrageiras de clima temperado.
3. Forrageiras de baixa qualidade têm a taxa de ingestão reduzida e,
consequentemente, reduzem a taxa de emissão de CH4 por bovinos.
4. Animais zebuínos podem gerar mais CH4 que bovinos de sangue
europeu.

? A question mark indicates uncertainty due to limited research, variable results, or lack/insufficient data on persistency of the effect.
1High = ≥ 30 percent mitigating effect; Medium = 10 to 30 percent mitigating effect; Low = ≤ 10 percent mitigating effect. Mitigating effects refer to percent change
over a “standard practice”, i.e. study control that was used for comparison. It is noted that most data used in this analysis are from short-term experiments. For most
