This study aimed to evaluate the economic and financial viability of the creation of Nellore cattle in feedlot in Brazil. To do so, we performed a meta-analysis of productive data of Brazilian research published in the last ten years, and before the data, simulated to economic analysis. Three scenarios were simulated, the first according to projections of commodity prices, the second with a reduction of 10% of those prices and the third with an increase of 10%. In first scenario the termination provided positive net income, with total factor productivity (TFP) of R$ 1.04. On the other hand, with the increase of 10% of the costs of production, there is an income and a negative rate of return. On the other hand, with a reduction of 10% of the costs of production, the system will only 1,289 animals and, at the same time, the TFP shall be 1.16, with a return rate of 16.32%. We observed payback with values of less than one year, but with an increase of 10% on the cost with feeding all indicators were negative. Sensitivity analyzes showed that in most scenarios evaluated, only in situations more unfavorable economic performance indicators were not attractive. A meta-analysis of data from the termination of bovine animals shows that, before the current scenario, the price of commodities provides favorable economic indices, but with a negative variation of 10% on the price of the same, the indicators are to be negative, even with the price of the @ remaining stable.

This study aimed to evaluate the economic and financial viability of the creation of dairy goats of Saanen breed and Anglo Nubian in system of family farming. The information of the technical parameters for financial analysis of this research were obtained in manuscripts the published in the last ten years in national journals. In face of these data was conducted a meta-analysis of data which generated the zootechnical date used for the simulations in this work. The simulation for milk production and calves from 72 dairy goats provided revenue above the cost of production, resulting in positive economic indicators for both scenarios assessed. The revenue generated by the systems that utilize the Saanen goats are bigger, considering that the production is greater. The financial analysis of systems proved to be viable over 8 years. In relation to the payback, both presented low return on investment applied. Sensitivity analyzes showed that in both systems evaluated, only in the most unfavorable situations, such as a reduction of 30% in both production and market price, the indicators of economic performance are not attractive, given that the time of return on investment is too long, especially in the rearing of goats Anglo Nubian. From the practical point of view, it is recommended the creation of both breeds, because the cost of deployment of the system can be purchased via funding.

Biofertilizers have been used in agroecological production with the aim of improving conditions for plant development. The objective of the research was to evaluate the effect of the application of biofertilizer on the initial development of chili peppers (Capsicum frutescens L.). The experiment was installed and conducted under field conditions from October to December 2018, in Chapadinha, city located in Maranhão. A completely randomized design was used, with 4 treatments and 5 repetitions. The experiment corresponded to the application of biofertilizer in concentrations T1: 0%, T2: 20%, T3: 40%, T4: 60% of goat biofertilizer diluted in water. The goat biofertilizer was made using 25 kg of fresh goat manure, 200 g of ash and 500 g of brazilian candy called rapadura. Seedlings with eight definitive leaves were transplanted 0.8 x 1 m apart. The first application of the biofertilizer was performed 15 days after transplanting and the following applications of the biofertilizer were carried out at 10-day intervals until data collection. At 60 days after transplantation, data for each variable were collected. It was observed that the variables responded well to the biofertilizer, revealing significant increases in the growth and development of the pepper plant. It is recommended 4 (four) applications of doses of goat biofertilizer with a concentration between 46% (460 ml L-1) to 48% (480 ml L-1) to obtain pepper seedlings with good phytotechnical quality, because in this range the best results were found for most of the analyzed variables.

Objetivou-se, com o presente trabalho, avaliar a preferência do consumidor em relação à proteína animal em Itapecuru Mirim, Maranhão, Brasil. Para a obtenção dos dados, foram aplicados 100 questionários semiestruturados, constituídos por 18 questões que abordavam aspectos relativos às condições de consumo e preferência por diferentes tipos de carnes no município. Os dados foram submetidos à análise estatística descritiva, com ênfase na distribuição de frequências relativas das respostas. Observou-se que os consumidores apresentam maior preferência por carne de frango (62%), seguidos pelos que preferem carne bovina (30%), e a suína sendo a menos consumida (8%). Sendo que o principal motivo da carne de frango ser a mais consumida o costume (30%), seguindo pelo valor nutritivo (25%), pelo preço acessível (24%), e os demais por outros fatores (4%). Além disso, observou-se que os consumidores que relacionam a produção animal com danos ao meio ambiente são a maioria (36%), seguindo dos entrevistados que não souberam responder (24%), aqueles que responderam que prejudica (22%) e que não prejudica (18%). Os resultados mostraram que o consumo de carne suína e bovina se mostrou limitado na cidade, sendo importante o emprego de estratégias que desmistificação sobre suas qualidades e demais características.
