Impacto dos índices reprodutivos na ecoeficiência da produção de leitões destinados a engorda em sistemas confinados

Abstract

Pork meat is the most consumed worldwide. However, pig farming may be playing a significant role in greenhouse gas emissions. In the processes necessary for the production of pork, those that occur within the production of piglets destined for finishing are highlighted. The sow has a fundamental role since on pig production. His annual productivity is essential indexes for the evaluation of the environmental and economic sustainability of a farm. About environment, we sought to understand what the productivity indicators would be, in the production of weaned piglets, which could be improved in order to reduce environmental impacts, like as: potential global warming and land use capacity. In the economic question, the goal was to identify the eco-efficiency of a kilogram of weaned piglet for the producing company. For such analyzes, the Life Cycle Assessment (LCA) method was used on studies of environmental impacts. And the Economic Value Added (EVA) method for the proposed economic analyzes. This work was divided into three chapters. The first was built from a systematic review that addressed the main scientific articles published in the last ten years, in the main scientific bases, on Life Cycle Assessment (LCA) and Added Economic Value (EVA) in pig farming. The second focused on applied LCA studies in relation to the reproductive indicators of sows that may interfere in the main categories of environmental impacts studied. And in chapter three, we looked for the influence of the same reproductive indicators with a focus on EVA and how these indicators can act to create value on a weaned piglet. Few studies have been found to analyze the variation in the reproductive indicators of the swine breeders on the environmental and economic impacts.
