| This study aimed to evaluate the inclusion of palm kernel cake in the diet for lactating crossbred cows in feedlot system, and its implications on economic viability. We used 12 crossbred Holstein x Zebu cows assigned to three 4 x 4 Latin Squares, in the following treatments: control (without inclusion of palm kernel cake in the diet); inclusion of 50, 100 or 150 g palm kernel cake (PKC) per kg in the total dry matter (TDM). Earnings per animal showed a reduction in values, this decrease in profitability is related to the increase in feed costs, specifically, and the costs with concentrate, which increased as the palm kernel cake was included in the treatments, 0, 50, 100 and 150 g kg-1 TDM. The effect observed for profitability affected the internal rate... |

| The addition of 0; 5; 10 and 15% cassava bagasse, based on the dry matter of the total diet of crossbred Holstein v. Zebu cows, was evaluated on milk production and composition and on the impacts of diet costs. The animals, weighing an average of 478.5 kg, were in the middle third lactation period. Diet with 15% cassava bagasse provided a 13.2% increase in production when compared to control. Feed conversion had a quadratic effect with minimum point at 4.2% of cassava bagasse inclusion. Crude protein, the only milk component that changed, increased linearly with the inclusion of cassava bagasse levels. Treatment with 15% cassava bagasse caused a more effective operational cost (42.8% higher when compared to control) and the highest leveling point for milk... |

| Quail egg production has experienced a steep rise in the last decade. Nutrition is the main factor affecting productive potential in the poultry industry, as appropriate nutritional management is necessary to ensure the maintenance of optimal physical conditions, growth and the production of high quality products. Meat and bone meal (MBM) has often been used in the poultry industry as an alternative and cost-effective source of protein in partial replacement of corn and soybean meal. However, there have been no studies to date that have investigated the effect of dietary MBM on the performance of quail or on the costs of production in the starter phase. This is particularly important considering that this phase is characterized by large investments by... |

| The breeding of crocodilians is still a recent activity in Brazil. Its peak was in the 1990's, but it has gaps in its production, as there are no norms for the commercial breeding of these animals in captivity. However, its economic potential is great, and the search for ecological balance and viability of commercial production has become a challenge among farmers of this activity. Therefor, the objective of the study was to economically analyze the production of Caiman crocodilus yacareon a farm located in Caceres, state of Mato Grosso, identifying relevant items of costs in the activity, as well as the parameters related to the profitability and viability of the activity. The economic results for the breeding of this animal were positive, with... |

| O modelo de produção adotado na suinocultura brasileira, principalmente na Região Oeste de Santa Catarina, é feita com os animais confinados em pequenas áreas, trazendo como conseqüência grande produção de dejetos. Este é diluído, através do uso de água para a limpeza das baias, aumentando seu volume. Seu lançamento nos cursos dágua da região está comprometendo a qualidade dos mananciais devido a contaminação bacteriológica e poluição por compostos químicos. Dessa forma, há necessidade de processos de tratamento para minimizar os problemas ambientais gerados por essa atividade. As lagoas de estabilização têm sido utilizadas, por apresentar um excelente desempenho quanto à eficiência de remoção da matéria orgânica, dos nutrientes e de coliformes fecais;... |

| The importance of Hospital Infection Control Committees (HICC) increases every year due to the emergence of multiresistant bacterial strains, hospital outbreaks, and other factors that cause HI. This demonstrates the fragility of the quality of hospital and medical care. Having a well-organized HICC benefits hospitals by improving quality, lowering costs and, most important, reducing patient morbidity and mortality. This review records the history of the development of HICCs, their present organizational structure, and offers recommendations for the best methods of infection surveillance. |

| Timber companies and policy makers in the Brazilian Amazon urgently need financial information on forest management. Results from a few experiments, case studies, and surveys have been groundbreaking, but are insufficient. A strategic partnership between timber companies and research organizations is needed to generate additional information. This paper presents a tool for monitoring production and costs of forest operations to facilitate such collaboration. The tool provides useful information for companies and, at the same time, generates reliable data for research. Selected results are presented on production, capacity, and costs to demonstrate the usefulness of the information that can be generated. These results are based on the first 2 years of... |

| Brazil is the world biggest producer of sugar cane with an area of 7x10(6) hectares. Mainly the system used for planting is the semi-mechanized one, which consists in opening the furrows with a machine, manually allocating the fractioned stalks and then covering the furrows done by the machines. The great amount of human labor used in the semi-mechanized system is becoming harder to find and also more expensive, indicating the need of a fully mechanized operation. Currently in Brazil these agriculture machines industries offers six different types of fully mechanized sugar cane planters (two types of whole stalks for planting and four using mechanized harvested stalks known as billets). All of them plant in two furrows simultaneously in 1.5 m row spacing.... |

| ABSTRACT The tariff flags on Brazil came into force in January 2015, applied to all electrical distribution agents of the national interconnected system (SIN) and all final consumers are being charged for this new model. Given this, the cost of electricity in irrigation suffered representative additions involving searches of alternatives, such as the use of diesel engines. This study aimed to analyze the costs and the total annual costs of pumping with diesel and electric operation in 3 regions of Brazil, considering the application of the tariff flags. We concluded that the Southeast region (SE) features an hourly cost of electricity above the Central-West (CO) and the Northeast (NE) regions at any adopted tariff, regardless of the time of pumping and the... |

| Many research works have being carried out on analyzing grain storage facility costs; however a few of them had taken into account the analysis of factors associated to all pre-processing and storage steps. The objective of this work was to develop a decision support system for determining the grain storage facility costs and utilization fees in grain storage facilities. The data of a CONAB storage facility located in Ponta Grossa - PR, Brazil, was used as input of the system developed to analyze its specific characteristics, such as amount of product received and stored throughout the year, hourly capacity of drying, cleaning, and receiving, and dispatch. By applying the decision support system, it was observed that the reception and expedition costs were... |
