At present there is a need to increase the productivity of systems due to an increasing demand for food and a shrinking area available for agricultural production. One solution is confinement of livestock and the use of genetic groups that are more efficient at transforming&#x...
Livestock is responsible for 14.5% of total anthropogenic emissions of greenhouse gases - GHG (FAO, 2013). Studies evaluating GHG from different lineages within of the same cattle breed are scarce. The objective of this study was to evaluate the intensities of methane emissions (kg...
The increase in greenhouse gases in the atmosphere is a widely discussed topic, with methane (CH4) generally mentioned as a gas with a global warming potential 25 times greater than carbon dioxide (CO2) (IPCC, 2006).
In Brazil, despite the lack of accurate statistics on the contribution of each type of system in total milk production, it is known that pastures represent the main feed source in most production systems (IBGE, 2010). However, a major concern with respect to this factor i...
The intensification of livestock production in tropical grazing areas should be based on the best use of the potential of pasture growth with a sustainability focus.
In recent decades, the concentration of methane and other greenhouse gases that cause the global warming is increasing, associated with human population growth and related activities, involving the agricultural environment.
Alongside the increasing global demand for red meat there is also increasing pressure from environmentalists to increase the productivity of systems. Recent studies have highlighted the environmental aspects of production systems, assessing methane (CH4) emissions, the principal gas emitted by ru...
This study aimed to evaluate sugarcane (Saccharum officinarum L) silage treated with calcium hydroxide - Ca(OH)2 - (slacked lime) as the only roughage source in a feedlot ration, regarding animal performance and meat quality. Forty five Canchim steers (22 months old, 345 kg body&#x...
O objetivo deste trabalho foi avaliar a variabilidade espacial e temporal do rendimento de milho irrigado para silagem, bem como seu retorno econômico. O estudo foi conduzido em área de 18.9 ha de produção de silagem de milho irrigado, no Município de São Carlos, no Estad...
Este estudo teve como objetivo avaliar a relação entre escores de reatividade para deslocamento e tensão e posição do rodamoinho na face de bovinos da raça Canchim em diferentes idades.
