| O objetivo deste trabalho é contribuir para a implementação de práticas agrícolas de menor impacto em áreas ambientalmente sensíveis. O Parque Estadual de Vila Velha está localizado nos Campos Gerais, Paraná, região de agricultura altamente tecnificada. Os sistemas de produção da área de entorno do Parque foram identificados em visitas e caracterizados em consultas com especialistas, engenheiros agrônomos, representantes comerciais e produtores. Três sistemas de produção de soja e milho (A, B e C), típicos da região, foram descritos, considerando-se as práticas mais comuns em rotação de culturas, escolha de produtos e operações de maquinário. Os sistemas A e B foram caracterizados como de alto nível de investimento e tecnologia, sendo que o primeiro seria... |

| Carcass characteristics and chemical composition of Longissimus muscle of 32 young bulls from four genetic groups slaughtered at 14 months old were evaluated. Experimental design was completely randomized and distributed into four genetics groups: 1. Caracu (CAR); 2. Canchin (CAN); 3. Charolais vs. Caracu (CHC) and 4. Aberdeen Angus vs. Canchin (AAC). Carcass dressing and carcass conformation were lower for CAR than CAN, CHC and AAC genetic groups. No difference has been reported with regard to moisture, ash, crude protein, total lipids and total cholesterol among four genetics groups. The genetic groups influence fatty acid profile on Longissimus muscle in bulls. Cattle with zebu genes had the highest rates in unsaturated fatty acids, saturated fatty... |

| This study was realized to evaluate the production and economic viability of finished beef cattle in feedlot in the Cerrado biome of Piauí State, Brazil. One hundred and fifty cattle -50 bulls (B) with an body weight of 283.0 ± 20.82 kg, at 30 months of age; and 100 cull cows (CC) with an body weight of 296.1 ± 17.80 kg, at 100 months of age- were used in a completely randomized design. The animal performance indicators for the evaluation of economic viability were initial age (months), slaughter age (months), was initial body weight (kg), final body weight (kg), daily feed intake (kg animal-1; kg kg-1 BW), diet cost (R$ kg-1 of diet), cost of kg produced (R$ kg-1 produced), and average price of the kg of meat for finishing (R$). The CC consumed more... |

| Artisanal fishing on the northern coast of Brazil is characterized by a set of different fishery modalities. Using a multidisciplinary approach, 20 fishery production systems were identified, with distinct characteristics regarding technology and purpose. The characteristics of each system were classified into five dimensions (ecological, economic, social, technological and political). Multidimensional scaling revealed that some of these 20 systems have greater similarities. Thus, a total of 10 groups were identified. |

| ABSTRACT The aim of the present study is to evaluate the economic viability of tomato cultivation in a system of organic farming, and to compare it with the conventional farming system. The fixed and variable costs of both cultivation systems were calculated, as well as the costs of disease control with the application of alternative products and pesticides. The revenues were computed using commercial production and the direct sales price. The total cost per area was higher in the conventional system, while the cost per plant was greater in the organic system, since it used a lower plant population density. In the conventional system, 2.33 times more was spent on plant management, due to the fact that the number of sprayings was greater than that carried... |

| Credence attributes (production system, animal welfare, traceability, among others) have acquired importance for meat products in developed countries, representing information that must be included on label. A personal survey was administered to 770 consumers in the Bío-Bío and La Araucanía Regions, Chile, to determine the utility of information contained on the label and acceptance of information referred to as credence attributes, as well as to distinguish different consumer segments. The packaging and expiry dates were the most useful aspects of the current information. The greatest degree of agreement with respect to information that should be included was a quality seal, type of animal, handling regarding animal welfare, production system and feeding.... |

| ABSTRACT: Technical and economic-financial performance of pantaneiro lamb finishing in feedlot (F) and semi-feedlot (SF) was evaluated. When analyzing the profitability, economic efficiency and the price sensitivity, was profit in all the scenarios evaluated. The gross margin (GM) was 69% and 52%, net margin (NM) was 65% and 48% and profitability index (PI) was 39% and 29%, as well as total productivity of factors (TPF) was R$1.53 and R$1.36, respectively, in the systems F and SF. Investment analysis showed that the activity is economically viable, remunerating all production factors and capital invested. Internal return tax was, respectively, 27% and 16% for the in feedlot and semi-feedlot systems. |
