Resumo: Avaliaram-se as curvas de crescimento de ovinos Morada Nova confinados, alimentados com níveis crescentes de concentrado na dieta (20, 40, 60 e 80% de concentrado). Foram utilizados 32 borregos, machos castrados. As curvas de crescimento foram analisadas usando os modelos de Brody e Bertalanffy. Os dois modelos se ajustaram, representando adequadamente o crescimento dos animais, com os valores de r² elevados e com os parâmetros significativos pelo teste t. Os valores de peso à idade adulta (A) foram semelhantes entre os tratamentos, porém, as taxas de maturação (k) foram maiores, nos dois modelos, à medida que o nível de concentrado aumentou. Conclui-se que ambos os modelos podem ser utilizados para predizer o crescimento de ovinos Morada Nova e que o aumento dos níveis de concentrado altera o comportamento das curvas de crescimento, reduzindo o tempo para atingir a idade adulta, devido ao aumento na taxa de maturação.
[Growth curves of Morada Nova sheeps feedlot fed diets with different concentrate levels]
Abstract: Growth curves of Morada Nova feedlot sheep fed diets containing concentrate levels (20, 40, 60 and 80% of concentrate). Thirty two male castrated lambs were used. Growth curves were adjusted using Brody and Bertalanffy models. Both models adjusted, presenting well animal growth, with high r2 values and significant parameters by t test. Mature age weight values (A) were similar among treatments, whereas maturation rates (k) were higher as concentrate level had increased. We have concluded that both models can be used to predict the growth of Morada Nova sheep in feedlot and level of concentrate increase changes growth curves behavior, decreasing the time to achieve mature age, owing to increase in the maturation rate.

The Atlantic Forest is one of the most diverse areas in the world and considered a hotspot. Several actions are needed for its preservation, among them the implementation of the Biodiversity Corridors. The Atlantic Forest has three biodiversity corridors and the Rio de Janeiro State, which harbors huge species diversity, is in the Serra do Mar Corridor. We developed socioeconomic, political and environmental indicators to present conservation strategies supported by a wide database. These indicators complemented the previous surveys of priority areas which emphasized biotic elements, and their integration allowed the elaboration of strategies for the conservation and management, regionally directed, to support actions to be implemented by the Government. The analysis was done considering three subjects: Anthropic Pressure, Physical and Biotic State, and Present Ability of Response. Data analysis followed a synthesis-aggregation schedule and the resulting database was taken to a workshop, where specialists proposed strategies and actions for the conservation. These strategies were discussed considering vegetation remnant distribution, biological relevance, environmental vulnerability, kind of anthropic pressure in the region and potential for success of the actions proposed, based on the ability of response. Rio de Janeiro State is very diverse in biotic, physical, political, socioeconomic and cultural aspects which demand specific actions for each region. So, depending on the present situation of the natural and anthropic environments and on the present and future sources of degradation, regionally directed actions are applicable. This specificity in conservation actions will enable that the State remnants will be more successfully protected.
