Aditivos nutricionais, Calorimetria respirométrica, Eficiência alimentar, Fermentação ruminal, Melhoramento genéticoResumo
O crescimento da demanda global por proteína animal tem intensificado a preocupação com as emissões de gases de efeito estufa (GEE) provenientes da produção pecuária. Ovinos e caprinos, embora com menor impacto absoluto que bovinos, demandam estratégias específicas de mitigação e mensuração de suas emissões. Esta revisão visa discutir criticamente os principais métodos utilizados para quantificação de GEE em pequenos ruminantes, destacando suas vantagens e limitações, bem como as estratégias nutricionais, genéticas e de manejo mais promissoras para a redução das emissões. Abordagens como calorimetria respirométrica, o uso de SF6, técnicas in vitro e ferramentas automatizadas foram analisadas, assim como o uso de aditivos, manipulação dietética, melhoramento genético e sistemas integrados de produção. A revisão enfatiza a necessidade de soluções integradas e adaptadas à realidade dos sistemas produtivos, buscando conciliar produtividade e sustentabilidade ambiental. Ao reunir e sistematizar conhecimentos atualizados, este estudo contribui para embasar decisões técnicas e políticas públicas voltadas ao desenvolvimento na produção de caprinos e ovinos.
