In order to evaluate the performance, carcass characteristics and meat quality of culled ewes finished in pasture or exclusivelywith grain, 41 culled Polwarth ewes, were assigned to six treatments: RY (ryegrass pasture), RYGO (ryegrass and whole grain oats), RYGM (ryegrass and whole grain maize), GM (whole grain maize), GO (whole grain oats), GS (whole grain sorghum). The finishing systemof the ewes influenced weight gain,wherein the GM and GS treatments increased daily weight gain. The GO treatment decreased the dressing percentage. Nonetheless, a*, h*, pH, cooking loss and tenderness were similar across dietary treatments. Using principal component analysis, the variables C18:2n6, h*, n6/n3, TBARS, total lipids, L* and b* were assigned as characteristics of meat from the feedlot animals, while the pasture finishing system produced meat with higher CLA and n-3 fatty acids but lower TBARS values indicating lipid stability.
-This is a case study that aimed at proposing a management method based on macroprocesses to determine and achieve strategic goals for a beef cattle enterprise in order to maintain or to increase the company's competitiveness.The method suggests using a series of tools mentioned in the literature that were organized providing logical reasons for the managers to build the management system. When mapping the processes of the studied enterprise, four macroprocesses were identified, which were sustained by 21 support processes, in addition to three management processes. The strategic aims were determined by the internal and external environmental analysis, resulting in five priority items, and the processes considered critical to achieve them were described by flow diagrams. The strategies to achieve the goals were determined by the Porter General Strategies method, where the differentiation option was chosen for the two main macroprocesses, whose action focuses were different.Key Words: agribusiness, agricultural systems, flow diagram, management system Aplicação de modelo de gestão por macroprocessos em empresa de pecuária de corte: um estudo de caso RESUMO -Objetivou-se, por meio de um estudo de caso, propor a implantação de um método de gestão orientado por macroprocessos para auxiliar na definição dos objetivos estratégicos de uma empresa de pecuária de corte, bem como das estratégias para seu atendimento, contribuindo com a manutenção e/ou o aumento da competitividade do negócio. O método propõe a utilização de ferramentas citadas na literatura, ordenadas de forma a orientar o raciocínio lógico dos gestores na montagem do sistema. No mapeamento dos processos da empresa estudada, foram identificados quatro macroprocessos, sustentados por 21 processos de apoio, além de três processos gerenciais. Os objetivos estratégicos foram determinados de acordo com a análise de ambiente interno e externo e resultaram em cinco itens prioritários; os processos considerados críticos para o seu atendimento foram descritos pelo método dos fluxogramas.

Inclusion of legume in grass pastures optimizes protein values of the forage and promotes improved digestibility. Therefore, we hypothesized that finishing steers on a novel combination of legumes and grass pasture would produce carcasses with acceptable traits when compared to carcasses from steers finished in feedlot systems. In this study, we evaluated the effects of finishing steers on three systems including: grazing legume–grass pasture containing oats, ryegrass, white and red clover (PAST), grazing PAST plus supplementation with whole corn grain (14 g/kg BW (SUPP)), and on a feedlot-confined system with concentrate only (28 g/kg BW, consisting of 850 g/kg of whole corn grain and 150 g/kg of protein–mineral–vitamin supplement (GRAIN)) on growth performance of steers, carcass traits and digestive disorders. Eighteen steers were randomly assigned to one of three dietary treatments and finished for 91 days. Data regarding pasture and growth performance were collected during three different periods (0 to 28, 29 to 56 and 57 to 91 days). Subsequently, steers were harvested to evaluate carcass traits, presence of rumenitis, abomasitis and liver abscesses. The legume–grass pasture provided more than 19% dry matter of protein. In addition, pasture of paddocks where steers were assigned to SUPP and PAST treatments showed similar nutritional quality. When compared to PAST, finishing on SUPP increased total weight gain per hectare, stocking rate, daily and total weight gains. The increase of weight gain was high to GRAIN than SUPP and PAST. Steers finished on GRAIN had high hot carcass weight, fat thickness and marbling score when compared to PAST. However, these attributes did not differ between GRAIN and SUPP. Abomasum lesions were more prevalent in steers finished on GRAIN when compared to PAST. Results of this research showed that it is possible to produce carcasses with desirable market weight and fat thickness by finishing steers on legume–grass pasture containing oats, ryegrass, white and red clover. Moreover, supplementing steers with corn when grazing on legume–grass pasture produced similar carcass traits when compared to beef fed corn only.
-It was aimed to propose a methodology for implementing a performance indicator system in a beef cattle company. Strategic goals and prioritization of process previously performed in the company was used as a support to the implementation. Possible indicators were listed and confronted with occasional restraints to its implementation and further analyzed by the Balanced Score Card (BSC) point of view. Subsequently, indicators were individually analyzed and their relationship with the company's strategic goals was determined. Seventeen indicators were selected, two under financial perspective, nine under process perspective, four under customer perspective, and two under development and learning perspective. The relationship analysis showed that the indicators support appropriate monitoring of the critical processes to achieve the strategic goals, thereby consolidating the management system.
-The objective of this study was to implement an indicator system that allows an overview of the performance at all levels of the company and to evaluate its overall performance using a consolidate general indicator. In the company studied, three business sectors were identified (crops, beef cattle production and viticulture) in addition to management sector, to which strategic objectives were determined. After that, it was mapped the macroprocesses that compose each business activity, a total of 14, and the critical indicators of performance to achieve the objectives, making up 50 indicators whose objectives were definied by the management team. It is possible to build consolidated indicators using the Analytic Hierarchy Process method, which allows weighing the relative importance of the indicators at each hierarchical level, that is, macroprocesses, activities and overall company performance for the achievement of the established goals.Key Words: management system, multicriteria analysis, process Construção de indicadores consolidados de desempenho para uma empresa do agronegócio: um estudo de caso RESUMO -Esta pesquisa foi realizada com os objetivos de implementar um sistema de indicadores que permita uma visão do desempenho em todos os níveis da empresa e avaliar seu desempenho global por meio de um indicador geral consolidado. Na empresa estudada, foram identificados três ramos de negócio (agricultura, pecuária e vitivinicultura) mais o setor administrativo, para os quais foram determinados objetivos estratégicos. Sequencialmente, foram mapeados os macroprocessos que compõem cada uma das atividades do negócio, num total de 14, e os indicadores críticos de desempenho para o atendimento dos objetivos, perfazendo um total de 50 indicadores, cujas metas foram definidas pela equipe de gestores.É possível a construção de indicadores consolidados utilizando o Analytic Hierarchy Process, o qual permite ponderação da importância relativa dos indicadores em cada nível hierárquico, ou seja, macroprocessos, atividades e desempenho global da empresa em busca dos objetivos traçados.Palavras-chave: análise multicritério, processos, sistema de gestão Revista Brasileira de Zootecnia
-The objective of this study is to identify demands of customers of a sire-producing company in Rio Grande do Sul, Brazil, by using a methodology adapted from quality function deployment tool. The adaptation consisted on the fact that matrices are treated in an unified manner among product and services due to the high perception of inter-relationship among these business components. The results evidenced that clients priorize traits related to the product, especially genetic value of the bulls. Service items were also highlighted, and they may be presented as an opportunity of differentiation among suppliers. Customer profile influenced priority order inasmuch as farmers with no technical services prioritized performance traits over genetic traits, opposing to those who were assisted and to technical consultants. Concerning to farm size, there were changes only in the tertiary level of the priority order of the demands. The adaptation of the methodology for joint analysis interfered in the results, especially in service prioritization. This study contributed to formatting a model for using quality function deployment in sire production, helping to identify quality demands and its priority levels for the population and researched company, and it may be used in further studies on the product beef sires.Key Words: agribusiness, genetics characteristics, quality demand Determinação das características da demanda para produção de touros por meio de um modelo conceitual de desdobramento da função qualidade: um estudo de caso RESUMO -Este trabalho foi realizado com o objetivo de identificar as demandas dos clientes de uma empresa produtora de touros de corte no Rio Grande do Sul por meio de uma metodologia adaptada da ferramenta desdobramento da função qualidade. A adaptação consistiu no fato de que as matrizes são tratadas de forma unificada entre o produto e os serviços, devido à percepção do elevado nível de inter-relacionamento entre esses componentes no negócio. Os resultados evidenciaram que os clientes priorizam as características relacionadas ao produto, especialmente o valor genético dos touros. Os itens de serviços também se destacaram, podendo configurar-se como uma oportunidade de diferenciação entre as empresas fornecedoras. O perfil dos clientes influenciou a ordem de priorização, uma vez que os produtores sem assistência técnica priorizaram as características de desempenho às genéticas, ao contrário dos assistidos e dos consultores técnicos. No tamanho da propriedade, só houve alterações na ordem de priorização no nível terciário das demandas. A adaptação da metodologia para a análise conjunta interferiu no resultado, principalmente na priorização dos serviços. O estudo contribuiu com a formatação de um modelo de uso do desdobramento da função qualidade na produção de touros, auxiliando na identificação da qualidade demandada e no seu nível de priorização para a população e empresa pesquisada, podendo ser utilizado em outros estudos para o produto touro.Palavras-chave: agronegócio, característic...
