O trabalho objetivou avaliar o desempenho, a viabilidade econômica e as características de carcaça de frangos de corte alimentados com dietas contendo níveis de inclusão (0,0; 7,5; 15,0; 22,5 e 30,0%) de farinha de varredura de mandioca (FVM). Foram utilizados 360 pintainhos de um dia, distribuídos em um delineamento em blocos casualizados com cinco tratamentos e seis repetições contendo 12 aves por parcela. Os parâmetros avaliados foram o consumo de ração, ganho de peso, conversão alimentar, custo da alimentação, renda bruta, margem bruta e rentabilidade. Aos 42 dias, foram abatidos dois frangos por parcela para avaliação do peso: da carcaça, dos cortes, das vísceras e da gordura total, para determinar o rendimento de carcaça e calcular as porcentagens de... |

This study aimed to evaluate the effect of corn silage (CS) replacement by cassava's foliage silage (CFS) on the production and quality of milk. Twelve lactating dairy cows were used in a randomized block experimental design with four treatments and three repetitions per block. CS was replaced by CFS at the levels of 0, 20, 40, and 60%. The replacement of CS by different levels of CFS had very low effect on the variables studied. Milk density decreased when the replacement level was increased. Fatty acids 4:0 and 6:0 presented a quadratic behavior, while fat acids 8:0, 10:0, and 15:0 presented a linear behavior as their concentrations fell when CFS diet content was increased. The CS replacement by 20% until 60% CFS resulted a significant decrease in the... |

The aim of this study was to conduct a cost-utility study of adefovir, entecavir, interferon alpha, pegylated interferon alpha, lamivudine and tenofovir for chronic hepatitis B in the context of Brazilian Public Health Care System. A systematic review was carried out for efficacy and safety. Another review was performed to collect utility data and transition probabilities between health states. A Markov model was developed in a time horizon of 40 years with annual cycles for three groups of: HBeAg positive, HBeAg negative, and all patients. These strategies were compared to a fourth group that received no treatment. Discount rates of 5% were applied and sensitivity analyses were performed. Tenofovir offered the best cost-utility ratio for the three... |

La presente investigación, es una evaluación económica que se realizó para obtener la rentabilidad del proyecto denominado: “Restauración Hidrológica Ambiental de la Microcuenca de Aporte a la Población de Mineral de Angangueo, Michoacán, (Microcuenca Carrillo-El Tigre); Mediante la Implementación de Prácticas de Manejo del Agua y Preservación de Suelos (MAPS)”. El proyecto se ejecutó después del fenómeno hidrometeorológico extremo que se presentó en febrero del 2010, dejando cuantiosos daños y pérdidas en el área afectada, la cual presentaba deterioro ambiental, agravando con ello la problemática. Ante tal situación, se propuso establecer prácticas de MAPS (presas de mampostería, gaviones, geocostales y piedra acomodada, así como un cabeceo de cárcava),... |

Leisure fishing, open to everyone and without a license, is a leisure activity in which many people are interested. Conversely to other harvesting activities such as fresh water fishing and hunting, it has practically not been studied until now (Appéré et Bonnieux, 2002). This study, dedicated to practice of leisure fishing at sea in the Gulf of Morbihan, set itself several objectives: - collect and assemble the available knowledge on regulations and practice of maritime leisure fishing - assess the amount of harvesting of certain recreational types of fishing and the economic impact generated by this activity, - highlight the problems of existing or potential cohabitations among the various users of the space and resources in the Gulf. - develop an... |

O presente trabalho objetivou comparar a viabilidade econômica do componente florestal na pequena propriedade rural, como sistema agrossilvipastoril ou como plantio convencional, no Município de Esperança do Sul, RS. O sistema agrossilvipastoril foi implantado com eucalipto, e o plantio florestal com eucalipto e acácia-negra. Foram utilizados apenas os dados do componente florestal, sendo obtidos por inventário florestal. Os indicadores selecionados para a análise econômico-financeira foram: valor presente líquido (VPL), valor anual equivalente (VAE), taxa interna de retorno (TIR), razão benefício/custo (B/C) e custo médio de produção (CMPr). A taxa de desconto utilizada foi de 7,5% ano-1. Os dois sistemas de produção foram considerados economicamente... |

ABSTRACT: Weed control is a crucial aspect in many conservation agriculture systems given that costs and time savings from avoiding tillage are closely linked to the use of effective and environmental friendly herbicides. This has led to the widespread use of glyphosate in farms, as it is a broad-spectrum, easily degradable, low- cost herbicide. The recent debate on the safety of glyphosate and on the excessive use of chemical herbicides in food production has caused concern on farmers about the possible economic effects of a virtual ban on glyphosate. The aim of this paper is to estimate the costs associated with an eventual prohibition of glyphosate in Spanish conservation agriculture areas. The costs of different alternative weed control strategies for... |

This paper outlines the impacts of ignoring the costs to the community of increased rural waterlogging and salinity. It identifies the cost of no further action, and the costs and benefits of undertaking a land and water management plan. The processes of developing and evaluating the plan are explained. Difficulties in obtaining data, both for the community and the economist, are discussed. Data availability then shapes the range of costs and benefits that can be evaluated. The paper looks at the process and results of a case study of a Land and Water Management Plan for an irrigation district in central New South Wales. The case study demonstrated all the complexities of community and professional conflict, difficulties in data availability, budget and... |

An investigation of the relative costs and benefits of marketing channels used by typical smallscale diversified vegetable crop producers is conducted. Using case study evidence from four small farms in Central New York, this study compares the performance of wholesale and direct marketing channels, including how the factors of risk, owner and paid labor, price, lifestyle preferences, and sales volume interact to impact optimal market channel selection. Given the highly perishable nature of the crops grown, along with the risks and potential sales volume of particular channels, a combination of different marketing channels is needed to maximize overall firm performance. Accordingly, a ranking system is developed to summarize the major firm-specific factors... |

Infrared thermographic images were used to evaluate the effect of the exposure of layers to cold. In this trial, 540 Isa Brown® layers with an average age of 69 weeks were housed in a conventional layer house typically used in Brazil during a period of cold environmental temperatures. Environmental and heat-transference data were recorded between July 13-16, 2010. It was verified that layers under cold stress conditions lost four times more energy that the recommendations trying to maintain their body temperature. Due to their reduced feed intake capacity, hens are not capable of increasing the availability of the metabolic energy required to maintain their body temperature and egg production, consequently resulting in economic losses. |
