Avaliou-se economicamente o efeito da suplementação protéico-energética em dois níveis de ingestão diária, 0,17% e 0,37% do peso vivo, sobre o desempenho de novilhos, em pastagens de Brachiaria brizantha cv. Marandu utilizando-se 14 animais por tratamento. Os tratamentos foram: SM - suplementação mineral (controle), SUP1 - suplementação protéico-energética com média de ingestão diária de 0,17% do peso vivo e SUP2 - suplementação protéico-energética com média de ingestão diária de 0,37% do peso vivo. Novilhos que receberam a suplementação protéico-energética SUP1 e SUP2 apresentaram maiores ganhos de peso, 0,655 e 0,746kg/animal/dia, respectivamente em relação aos que receberam apenas suplementação mineral, 0,535kg/animal/dia. Os maiores lucros operacionais, observados para os animais dos tratamentos SUP1 e SUP2. 67,12 e 72,08 R$/animal/período, respectivamente, em relação aos do tratamento controle, 66,67 R$/animal/período; os resíduos para remuneração foram de R$59,92, R$55,10 e R$54,85/animal/período, para novilhos que receberam SUP2, SUP1 e SM, respectivamente e sugerem que a suplementação protéico-energética possibilitou maior retorno econômico. | The effects of protein and energy supplements at two levels of daily intake - 0.17% and 0.37% of live weight (LW) - on the performance of steers under Brachiaria brizantha cv. Marandu pasture were economically evaluated using 14 steers per treatment. Treatments were: MS - mineral supplementation (control), SUP1 - protein and energy supplementation with an average daily intake of 0.17% of live weight, and SUP2 - protein and energy supplementation with an average daily intake of 0.37% of live weight. Steers of treatments SUP1 and SUP2 showed higher weight gains, 0.655 and 0.746kg/animal/day, respectively, in relation to those in the control group, 0.535kg/animal/dia. Higher operational profits were observed, R$67.12/animal/period and R$72.08/animal/period, for steers from SUP1 and SUP2 treatments, respectively; in comparison to the R$66.67/animal/period for MS treatment. The residual remunerations of R$59.92, R$55.10, and R$54.85/animal/period, for steers from SUP2, SUP1, and SM, respectively, strongly suggest that energy-protein supplementation allow higher economic profit.

Este proyecto describe la fabricación de una aerobomba Darrieus de eje vertical para la extracción de agua, para consolidar un plan de negocio orientado a la fabricación de la aerobomba en la zona rural de Villavicencio-Meta (Centro Poblado Barcelona, Vereda Apiay), que conecta la bomba a través de energías limpias reduciendo costos. El proyecto se originó por varias razones. (i) existe la necesidad de potenciar la utilización de aerobombas que son energías renovables no convencionales, tanto a nivel regional y local, es necesario desarrollar un sistema de extracción de agua que reduzca los impactos ambientales, haciendo uso sostenible y no depender de los combustibles fósiles. (ii) existe una importante oportunidad para este tipo de proyectos por ser un producto innovador y conocer sus características técnicas, beneficios y oportunidades de mercado. (iii) la evolución de la tecnología eólica ha permitido que las aerobombas estén en condiciones de competir con sistemas convencionales de bombeo. (iv) Villavicencio cuenta con la disponibilidad de velocidad de viento de 2 m/s para el desarrollo de este tipo de negocios. En el estudio, se realizó los análisis de mercado, técnico, administrativo y legal, y financiero, el propósito fue revisar las disposiciones, obligaciones y beneficios que podrían afectar o favorecer la viabilidad del proyecto. El plan de negocios se realizó en cuatro fases, en la primera parte del estudio se definió el análisis de mercado, se estableció el tipo de aerobomba a utilizar y cuáles son sus empresas competidoras, el mercado potencial determina las oportunidades existentes en la industria con la descripción del mercado objetivo al cual se dirigió el negocio. En la segunda parte, estudio técnico se describen las principales características de una aerobomba y se explican los aspectos claves del negocio. En el estudio administrativo y legal, se hizo la estructura organizacional, formación de una empresa, su legislación vigente y organizaciones de apoyo. En la cuarta parte de la investigación en el estudio financiero, la metodología utilizada corresponde a técnicas financieras de preparación y evaluación de proyectos. El criterio para evaluar la rentabilidad del negocio se basa en la evaluación presente, futura de los costos y beneficios esperados, medidos a través de la construcción del flujo de caja, el VAN del proyecto fue positivo dando como resultado que es rentable y viable. | This project describes the business plan for the manufacture of a vertical shaft Darrieus wind pump for water extraction. In order to consolidate a business plan aimed at the manufacture of the wind pump and use in rural area of Villavicencio-Meta (Centro Poblado Barcelona), Vereda Apiay), which connects to the pumping system through clean energies, reducing costs. The idea of the project originated for several reasons, such as: (i) the necessity to promote the use of wind pumps that are part of non-conventional renewable energies, both regionally and locally, where it is necessary to develop a water extraction system that reduces environmental impacts, making sustainable use of the dependence on fossil fuels. (ii) There is an important opportunity for this type of project because it is an innovative product where its technical characteristics demonstrate benefits and opportunities in the market. (iii) The evolution in wind technology has allowed the wind pumps to compete with conventional water pumping systems. (iv) Villavicencio has the availability of wind speed of 2 m/s for the development of business. This study showed the analysis of market, technical, administrative legal, and financial. The main of this review analyze the provisions, obligations and benefits that could affect or favor the viability of the project. The business plan was carried out in four phases, in the first part of the study the market analysis was defined, where the type of wind pump to be used is established and which are its competing companies, the potential market and the opportunities existing in the market are determined. In the second part, a technical study describes the main characteristics of a wind pump and explains the key aspects of the business. In the administrative and legal study, the organizational structure, formation of a company, its current legislation and support organizations were made. In the fourth part of the research the methodology used corresponds to financial techniques of preparation and evaluation of projects for the financial study of the project. The criterion for evaluating the profitability of the business is based in the present and future evaluation of the expected costs and benefits, measured through the construction of the cash flow, the NPV of the project was positive, resulting its profitability and feasibility. | Ingeniero Ambiental | http://www.ustavillavicencio.edu.co/home/index.php/unidades/extension-y-proyeccion/investigacion | Pregrado
