Resumo(s)
O objetivo principal deste trabalho foi a elaboração da Análise do Ciclo de Vida (ACV) de duas fórmulas de alimento composto para o acabamento de frangos. Para tal, recorreu-se a fórmulas já existentes, e fez-se a ACV com recurso ao software SimaPro. Para uma melhor fundamentação do estudo, abordou-se nos capítulos 2 e 3 a disponibilidade das matérias-primas e a sua adequação às necessidades nutritivas das aves. Nos capítulos 4 e 5 verificou-se quais eram as ferramentas de análise que permitiam avaliar alternativas mais sustentáveis para a produção animal. Nos capítulos finais, avaliou-se o impacte ambiental das fórmulas, através da ACV, e verificou-se se as diferenças de formulação tinham consequências no desempenho das aves. Uma das principais conclusões retirada deste estudo foi que o transporte das matérias-primas até à fábrica é um dos fatores que mais impacta a produção do alimento composto. No desempenho das aves, não se verificou grandes diferenças nas 2 formulações já que, atualmente, as fórmulas se encontram otimizadas para que esse não seja um fator diferenciador.
The main objective of this study was to conduct a Life Cycle Assessment (LCA) of two compound feed formulations for broiler finishing. For this purpose, existing formulations were used, and the LCA was carried out with the SimaPro software. To provide a stronger foundation for the study, Chapters 2 and 3 addressed the availability of raw materials and their suitability for meeting the birds’ nutritional requirements. Chapters 4 and 5 examined the analytical tools that allow the assessment of more sustainable alternatives for animal production. In the final chapters, the environmental impact of the formulations was evaluated through the LCA, and it was assessed whether formulation differences had consequences on broiler performance. One of the main conclusions drawn from this study was that the transportation of raw materials to the feed mill is one of the factors with the greatest impact on compound feed production. Regarding bird performance, no significant differences were observed between the two formulations, since current feed formulations are optimized to prevent this from being a differentiating factor.
