Resumo
Há um processo de intensificação na produção animal, em particular na produção de ovos. Esse processo compromete o bem-estar na criação das aves. Os consumidores e a sociedade, de uma forma geral, têm pressionado para melhores condições de bem-estar na avicultura de postura, condenando o uso de gaiolas, resultando em uma pressão para mudanças nos sistemas produtivos. Estas mudanças implicam em investimentos e novos custos associados à promoção do bem-estar animal. O objetivo deste trabalho é avaliar essa mudança sob o ponto de vista do bem-estar animal, da qualidade do produto, e financeiramente. Esta avaliação foi feita por meio da modelagem de distintos sistemas produtivos, segundo o uso de gaiolas. O levantamento dos indicadores de bem-estar, qualidade dos ovos e financeiros, foi realizado em dois produtores e três sistemas produtivos, nos municípios de Bastos e Tupã, estado de São Paulo. Foram realizadas observações não sistemática nas granjas quanto ao atendimento de princípios que indicam melhores condições de bem-estar animal. Para qualidade dos ovos, Unidade Haugh, Peso do Ovo e Resistencia das Casca, foram medidos nos 3 sistemas, em 8 coletas de amostras aleatórias de 60 ovos. A análise financeira, se deu por meio da aferição dos custos operacionais e totais de produção, além da receita por ovo e prazo de retorno de investimento das granjas. A granja alternativa atendeu a mais princípios de bem-estar animal, apesar de ter apresentado maior incidência de patologias nos lotes. Quanto à qualidade, apenas no índice de Unidade Haugh a granja alternativa esteve em melhores condições, A granja convencional apresentou melhores resultados qualidade externa do ovo e os custos operacionais foram menores do que os da granja alternativa.
There is a processo of intensification in animal production, particularly in the eggs production. This process compromises the well-being in the poultry breeding. Consumers and society, in general, have been pushing for better welfare conditions in poultry farming, condemning the use of cages, resulting in pressure for changes in production systems. These changes imply investments and new costs associated with the promotion of animal welfare. The objective of this investigation is to evaluate this change from the point of view of animal welfare, product quality, and financially. This evaluation was made through the modeling of different productive systems, according to the use of cages. The survey of welfare, egg quality and financial indicators was carried out in two producers and three production systems, in the municipalities of Bastos and Tupa, State of Sao Paulo. Non-systematic observations were made on the farms regarding compliance with principles that indicate better animal welfare conditions. For egg quality, Haugh Unit, egg weight and bark resistance, were measured on the three systems in eight random sample collections of 60 eggs. The financial analysis was done by means of the measurement of the operational and total costs of production, besides the revenue per egg and the term of investment of the farms. The alternative farm met more animal welfare principles, despite having a higher incidence of pathologies in the lots. As for quality, only the Haugh Unit index was the alternative farm better off. Conventional farms had better external egg quality and lower operating costs than alternative farms.
