RESUMO -Foram utilizados 1200 pintos da linhagem Label Rouge, com peso médio inicial de 41,0 ± 0,55 g, distribuídos em um delineamento inteiramente casualizado, em esquema fatorial 2 x 5, (com e sem acidificante X 0, 25, 50, 75 e 100% de silagem de grãos úmidos de milho -SGUM). Foram determinados o ganho de peso (GP), consumo de ração (CR), conversão alimentar (CA), além da análise morfométrica e de microbiota intestinal, rendimento de carcaça e de cortes. De 1 a 63 dias, houve efeito quadrático (P<0,05) da SGUM sobre o CR e CA. Houve interação (P<0,05) entre os níveis de SGUM e a adição de acidificante para o rendimento de carcaça, e de cortes (asa e peito) e fígado das fêmeas. Os machos apresentaram interação (P<0,05) entre os níveis de SGUM e o acidificante para carcaça, sobrecoxa, peito e gordura. Houve interação (P<0,05) da inclusão de SGUM e a adição ou não de acidificante para a contagem de Lactobacillus aos 63 dias. Houve efeito quadrático da SGUM para o tratamento com acidificante, e as criptas apresentaram maior diâmetro para o tratamento sem acidificante. Os resultados sugerem que frangos caipiras alimentados com até 50% de SGUM com acidificante apresentam boas características de carcaça e de cortes e não sofrem danos sobre os parâmetros intestinais.Palavras-chave: Alimentos alternativo.

The chicks were distributed over a completely randomised design in a 2 x 5 factorial scheme (with and without acidifier, and 0, 25, 50, 75 and 100% high-moisture corn silage -HMCS). Weight gain (GP) was determined, together with feed intake (CR), and feed conversion (CA), morphometric analysis, an analysis of intestinal microbiota, and the yield from the carcass and cuts. From 1 to 63 days, a quadratic effect (P<0.05) was seen from the HMCS on CR and CA. There was an interaction (P<0.05) between the levels of HMCS and the addition of acidifier on carcass, cuts (wing and breast) and liver yield in females. For males, there was an interaction (P<0.05) between the levels of HMCS and acidifier on carcass, drumstick, breast and fat. There was an interaction (P<0.05) between the inclusion of HMCS and the addition of acidifier on the Lactobacillus count at 63 days. There was a quadratic effect from the HMCS for the treatment with acidifier, and the crypts showed a greater diameter for the treatment without acidifier. The results suggest that range chickens, fed with up to 50% HMCS with acidifier, display good characteristics for the carcass and cuts, and suffer no damage to the intestinal parameters.

“…Movimentos em busca da agricultura sustentável surgiram no Brasil como resposta socioambiental aos problemas provenientes da "revolução verde" e ganharam espaço assumindo expressão mais visível no início da década de 90, período de grande sensibilidade ecológica/preservacionista. (SANTOS et al, 2014;ASSAD e ALMEIDA, 2004).…”

“…Diante disso, a sociedade têm demonstrado preocupação, e incentivado buscas por alternativas corretas para preservação ambiental. Por isso, na década de 70, meios de controle alternativos e sustentáveis foram amparados por movimentos sociais, sendo caracterizados como "agricultura alternativa" (SILVA e BRITO, 2015;GOMES e BARIZON, 2014;MENEZES, 2003;SANTOS et al, 2014;ASSAD e ALMEIDA, 2004).…”

“…Other aspects worth mentioning are the improvement in the population's nutritional standards, a reduction of the temperature inside the residences in the light of the local climatic conditions, the stimulation of sustainable productive activities within the settlement area and improvements in the relations with the middle class residents living in the surrounding areas. The quest for greater sustainability of the urbanization through the practice of family agriculture has been addressed by Dos Santos et al (2014). The positive consequences of adopting green roofs can be examined in greater detail in the literature of Mary et al (2008) in which there are descriptions of the results of experiments with green roofs carried out in the Teófilo Moreira da Costa Municipal School located near the settlement and which was also the site of actions of the HIDROCIDADES project.…”

The paper presents a methodological proposal in the form of a framework for redesigning informal settlements based on Low-impact Design and Development methodology. It involves the management of rainwater through the implementation of urban infrastructure on local scale in a decentralized and collaborative manner. It served as an object of study the region of Baixada de Jacarepagua, a vector of expansion of the city of Rio de Janeiro. The proposed framework adopts Action-Research methodology. The stages envisaged in the framework are: (i) initial, which involves approaching the community, establishing bonds and setting up a management group, (ii) diagnosis, and (iii) project. The application of the framework is demonstrated by means of a case study of the community, which typifies the slums in areas of marshland and the peripheral urban landscape. It is believed that this framework can guide the urban redesign of other communities within the perspective of sustainable development.
