| Para a implantação de uma atividade econômica é necessária sua avaliação econômica e financeira, que verifique as oportunidades e os riscos inerentes ao projeto. Por este motivo, os objetivos deste estudo foram os de determinar indicadores de viabilidade de custo-benefício dos investimentos, para um projeto de criação comercial de Pacas (Agouti Paca), em regiões do entorno das matas de Minas Gerais. Para esta análise foram determinados índices econômicos para a criação de quarenta matrizes e oito reprodutores de pacas, em sistema intensivo de produção, sob dois cenários econômicos. Os resultados destacaram como principais custos para a implantação da atividade a aquisição dos animais (62%; 6%) e a construção das instalações (36%; 89%), nos dois cenários,... |

| ABSTRACT The objective of the study was to evaluate the effect of nutritional plans on the productive and economic performance of Hubbard Flex broiler chickens. A completely randomized experimental design was applied, consisting of five treatments. Treatments consisted of five different nutritional plans: a basal diet containing the nutrient and energy levels recommended by literature and designated reference diet; two diets containing 1.5% and 3% lower levels than the reference diet; and two diets containing 1.5% and 3% higher levels than the reference diet (-3%, -1.5%, reference plan, +1.5% and +3%). Feed intake (FI), body weight (BW), feed conversion rate (FCR), livability (L) and productive efficient index (PEI) were determined when broilers were 42... |

| ABSTRACT The objective of this study was to evaluate the effects of dietary nutrient levels on performance, carcass yield, commercial cuts, digestibility and economical viability of broilers from 1 to 42 days of age. During the experiment, 180 COBB 500™ chicks were housed in metal batteries and subjected to a completely randomized design in a 2x3 factorial arrangement, of two sexes and three diets (male, female and mixed), totaling 6 treatments and 6 repetitions of 5 birds each. Data were subjected to statistical analysis and the means were compared using the Tukey test, at 5% probability. The results indicate the effect of sex on performance and commercial cuts, except for breast and thigh fillets, in which males and females showed similar results when... |

| ABSTRACTThe objective of this study was to evaluate programs of supplementary lighting for calves in individual shelters with different roof materials, as a strategy to stimulate concentrate consumption and the reduction of the milk feeding period and increase financial viability. Twenty seven dairy crossed Holstein × Gir female calves were randomly distributed in individual shelters with three different roofing materials (cement fiber tile, recycled tile and thatched roofs), associated with three different light duration (12, 16 and 20 h) and with three repetitions. The experimental design was completely randomized in 3 × 3 factorial arrangement. There was no interaction between the types of roofs × supplemental light; also, there was no significant... |

| ABSTRACT The use of cobalt (Co) and molybdenum (Mo) along with the co-inoculation with Azospirillum brasilense on soybean can contribute to biological nitrogen fixation (BNF), allowing higher yields. Thus, this work aimed to study the technical and economic viability of soybean in the Cerrado, according to the mode of application of Co + Mo, and seed or leaf co-inoculation with Azospirillum brasilense. The experiment was conducted in Selvíria-MS, in a no-tillage system in an Oxisol, arranged in a randomized block design with six treatments (seed application of two treatments with Co + Mo, with or without inoculation with A. brasilense, respectively; Foliar application of Co + Mo at soybean V3 stage; Foliar application of Co + Mo together with A. brasilense... |

| This experiment assessed the effect of feed restriction in rabbits on performance and economic viability of the activity. Sixty New Zealand White rabbits, weaned at 33 days and slaughtered at 81 days of age, were used. The design was of randomized blocks with four treatments and five replications. The treatments were, as follows: 1 - free feeding, 2 - feed restriction from 35 to 40 days of age (50 g/d/rabbit), 3 - feed restriction from 54 to 61 days of age (90 g/d/rabbit) and 4 - feed restriction from 33 to 40 days (50 g/d/rabbit) and from 54 to 61 days of age (90 g/d/rabbit). There was no difference in the performance and carcass parameters, indicating that there was compensatory growth in the rabbits that suffered feed restriction. The best gross margin... |

| Dois experimentos foram conduzidos com o objetivo de determinar o valor energético do milheto (Pennisetum glaucum) ADR 7010 e avaliar o desempenho e a viabilidade econômica dos frangos de corte alimentados com rações contendo níveis crescentes de milheto ADR 7010. No Experimento 1 foram utilizados 72 frangos de corte com 21 dias de idade em um delineamento inteiramente casualizado com dois tratamentos, seis repetições de nove aves cada. A energia metabolizável aparente do milheto foi de 3.362,24 kcal kg-1 de matéria seca e 3.066,00 kcal kg-1 de matéria natural e o teor de proteína bruta de 12,6%. No Experimento 2 foram utilizados 960 pintos de um dia de idade, distribuídos em um delineamento inteiramente casualizado com seis tratamentos, cinco repetições e... |

| This studyaimed to assess different holding pen climatization systems for dairy cattle through environmental variables, milk production and economic indexes. Sixteen lactating cows were used, distributed in a 4 x 4 Latin square design consisting of four groups of four animals, assessed in four periods, seven days each, and in four holding pen environments: SUN– external environment (in the sun), SHA– 80%-protection polypropylenemesh shading, SHA + SPR– 80% polypropylene mesh shading + water sprinkling, SHA + SPR + VEN – 80% polypropylene mesh shading + water sprinkling + ventilation. The animals remained for 30 minutes in their respective environments. In this period, environmental variables were collected using data loggers, and the milk produced, in kg,... |

| 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... |

| Abstract Electricity is undoubtedly one of the most important resources in the modern world. As the demand for electric energy increases, conventional resources that are transformed into electric energy are being exhausted, generating a need to search for alternative sources, resulting in a significant increase in energy costs. This study presents an integrated project of an intelligent microgrid and energy management aimed at reducing energy costs. At the Federal University of Paraná (UFPR), electricity represents an annual cost of over BRL 13 million, which is the third largest operating expense of the university. In addition, the public education budget in Brazil has been decreased in recent years. Therefore, this study was conducted within the scope of... |

| ABSTRACT: The aim of this study was to evaluate the economic viability of the use of a lactation induction protocol in Holstein heifers. Were collected data of nutritional, reproductive and sanitary management pre and post-lactation period from 30 induction heifers (IG) and 30 pregnant heifers (CG). All animals were inseminated around 14 months of age and started lactation at 23±4 months. The animals of IG were heifers do not pregnant after two inseminations and natural service e were induced to lactation according to protocol: from the 1st to the 8th day, 30 mg of estradiol benzoate were administered daily, together with 300 mg of progesterone. From the 9th until the 14th, animals only received daily doses of 20 mg estradiol benzoate. On 16th day, 0.56... |
