Dynamics of the ruminal microbial ecosystem, and inhibition of methanogenesis and propiogenesis in response to nitrate feeding to Holstein calves
(Elsevier, 2021-12)It is known that nitrate inhibits ruminal methanogenesis, mainly through competition with hydrogenotrophic methanogens for available hydrogen (H2) and also through toxic effects on the methanogens. However, there is limited ... -
Emisiones de gases de efecto invernadero: simulación de un sistema ganadero de carne típico de la región central Argentina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-04)La demanda global de alimentos estimula el aumento de la producción agro-ganadera para garantizar la disponibilidad alimentaria pero, a la vez, plantea desafíos en cuanto al aumento en las emisiones de gases de efecto ... -
Enteric methane emission from Sheep fed with rhodes grass hay (Chloris gayana) alone or supplemented with dried distillers’ grains with solubles
(MDPI, 2022-09)Livestock systems based on subtropical and tropical pastures are characterized by the low productivity of livestock due to the poor nutritional value of the forage (low nitrogen concentration and digestibility, and high ... -
Greenhouse Gas Emissions from Green-Harvested Sugarcane With and Without Post-harvest Burning in Tucumán, Argentina
(2014-06)Concentrations of greenhouse gases (GHG) in the atmosphere are increasing due to anthropogenic actions, and agriculture is one of the most important contributors. This study quantified GHG emissions from green-cane harvested ... -
Improving the accuracy of beef cattle methane inventories in Latin America and Caribbean countries
(Elsevier, 2023-01)On-farm methane (CH4) emissions need to be estimated accurately so that the mitigation effect of recommended practices can be accounted for. In the present study prediction equations for enteric CH4 have been developed in ... -
Increased Nitrogen Retention and Reduced Methane Emissions of Beef Cattle Grazing Legume vs. Grass Irrigated Pastures in the Mountain West USA
(MDPI, 2022-01)Grazing studies were carried out over a 5-year period using pregnant cows, yearling calves and 2-year-old heifers to investigate the influence of diet on intake, methane (CH4) emissions and retention of nitrogen (N). ... -
Intensidad de emisiones de metano en sistemas de producción de carne con destete hiperprecoz
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2019-06)La producción de metano entérico (CH4) representa una pérdida de eficiencia de utilización de la energía de sistemas de producción bovina y además constituye el principal gas de efecto invernadero (GEI) generado por la ... -
Modelación productiva, económica y emisión de metano en sistemas de cría vacuna de Bahía Blanca y Coronel Rosales
(2018-08)El objetivo de este estudio de simulación fue evaluar la respuesta productiva, económica, emisión de metano y el valor marginal del agregado de alimento extra (VMA) en diferentes sistemas la cría vacuna de Bahía Blanca y ... -
The relevance of methane emissions from beef production and the challenges of the Argentinean beef production platform
(Elsevier, 2014-11)The livestock sector faces the challenge to respond to the growing demand for animal protein from an expanding population while reducing environmental impact through GHG emissions. Globally about 2.836 million tons of ... -
The Use of Temperate Tannin Containing Forage Legumes to Improve Sustainability in Forage–Livestock Production
(MDPI, 2021-11-09)Greenhouse gas emissions from ruminant livestock production systems contribute significantly to the environmental footprint of agriculture. Emissions are lower for feedlot systems than for grass-based systems primarily ... -
Towards a baseline for reducing the carbon budget in sugarcane: three years of carbon dioxide and methane emissions quantification
(2018-11)Sugarcane straw burning or removal and N fertilization are management practices that modify the input of carbon (C) to the soil affecting greenhouse gases emissions and the potential of the soil for C sequestration. This ...
