Abstract: This work was conducted with the objective of evaluating the influence of different levels of energy in the ration on the performance and carcass characteristics of sheep, finished in feedlot and slaughtered with 32 kg of live weight. Three treatments were evaluated: 2.23, 2.54 and 2.85 Mcal of ME/kg of DM, being the last treatment the recommendation of the National Research Council - NRC (1985) for weight daily gains of 250 g in lambs. Eighteen, intact, Texel crossbred lambs were used; six per treatment. Lambs were fed with isoprotein rations (16.70% CP). The energy recommendations proposed by the NRC (1985) resulted in smaller weight gains than expected. The energy level had a linear effect (P < 0.05) on weight gain (?=-190+141X). Diets with greater energy supply rendered greater weight gains, and consequently less time for the termination of the lambs. Carcasses of animals slaughtered with similar weights presented different morphological characteristics. Este trabalho foi realizado com o objetivo de avaliar a influência de diferentes níveis de energia na ra o sobre o desempenho e características da carca a de ovinos terminados em confinamento e abatidos aos 32 quilos de peso vivo. Foram avaliados três tratamentos: 2,23, 2,54 e 2,85 Mcal de EM/kg de MS, sendo o último tratamento, a recomenda o estipulada pelo National Research Council - NRC (1985), para cordeiros com ganhos diários de 250 gramas. Foram utilizados 18 cordeiros inteiros, seis por tratamento, mesti os Texel, alimentados com ra es isoprotéicas (16,70% PB). As recomenda es de energia propostas pelo NRC (1985) propiciaram ganhos de peso menores do que os esperados. O nível de energia teve efeito linear (P < 0,05) sobre o ganho de peso (y =-190+141X). Portanto, dietas com maior aporte energético propiciaram maior ganho de peso e consequentemente reduziram o tempo para a termina o dos cordeiros. Carca as de animais abatidos com pesos similares apresentaram características morfológicas diferentes.

Abstract: Se presenta una aplicación de la simulación Monte Carlo como una herramienta para la toma de decisiones en una planta fabril. Se ha usado el caso de una línea de montaje de tres estaciones dedicadas a producir termostatos de plancha en una instalación de fabricación de artículos domésticos. Inicialmente la planta fue dise ada para generar una tasa de producción de 3500 montajes por semana, mientras que la producción real solo alcanzaba un 85% de este valor. Se estudió los tiempos y movimientos y los resultados se utilizaron como una base para la mejora de la operación actual de la línea usando el método de simulación estocástica. Dicha simulación inicial posibilitó la identificación de los problemas claves responsables de la limitada tasa de producción. Varias otras simulaciones fueron llevadas a cabo para probar diferentes mejoras de la línea de montaje. Monte Carlo simulation is employed as a tool for decision making on a manufacturing company.

Abstract: The search for forage alternatives in dry season that are economically viable has taken many livestock farmers to use the sugar cane in the ruminants feeding. This bibliographical review was realized with the objective to discuss the sugar cane nutritional characteristics and its utilization in ruminants feeding. Positive and negative aspects had been told as the production potential, the growing easiness and nutritional limitations. Information had been approached as chemical composition, by-product uses and possible treatments, such as the chemical treatment that increases its digestibility and intake, improving the animals performance. The results of different researches suggest some ways of sugar cane use for the satisfactory results obtaining. However, considering that the sugar cane is poor in proteins and mineral elements, there is necessity of protein supplementation to supply the nutritional requirements. A busca por alternativas de volumosos na época da esta o seca, que sejam economicamente viáveis, tem levado muitos pecuaristas a utilizarem a cana-de-a úcar na alimenta o de ruminantes. Esta revis o bibliográfica foi realizada com o objetivo de discutir as características nutricionais da cana-de-a úcar e suas formas de utiliza o na alimenta o de ruminantes. Foram relatados os aspectos positivos e negativos como o potencial de produ o, facilidade de cultivo e as limita es nutricionais. Abordaram-se informa es como composi o química, utiliza o de subprodutos e possíveis tratamentos, tal como, o tratamento químico que aumenta a sua digestibilidade e consumo, melhorando o desempenho dos animais. Os resultados de diferentes trabalhos de pesquisa sugerem várias formas de utiliza o da cana-de-a úcar para a obten o de resultados satisfatórios. Entretanto, considerando que este é um alimento pobre em proteínas e minerais há necessidade de suplementa o destes componentes para suprir as exigências nutricionais das diferentes categorias animais.
