Trata-se de um estudo de caso descritivo e explanatório. O trabalho descreve a trajetória evolutiva do sistema de produção do EAS, caracterizando-o em três fases distintas. Na Fase I, que se inicia em 2008 e se estende até julho 2014, identifica-se uma significativa influência dos fatores históricos da produção naval no Brasil que teve forte influência do paradigma Taylorista/Fordista, e pode ser sintetizado pelo fato de que a produção de navios era percebida enquanto uma ´obra´ com a gestão das diversas ´disciplinas´. A Fase II, que ocorreu entre julho de 2014 e janeiro de 2016, constituiu-se em uma etapa de transição que teve como elemento central o objetivo de modificar a cultura organizacional da empresa, o que foi efetivado através da adoção de conceitos tais como: 5S, mini fábricas e Kaizens com foco na melhoria dos fluxos produtivos e qualidade focada no processo. Já a Fase III, que inicia em janeiro de 2016, tem como evento crítico a criação de uma maquete em escala real do EAS que objetiva criar uma visão holística da empresa e do sistema de produção. A Fase III tem como embasamento teórico o Sistema Toyota de Produção e a Teoria das Restrições (TOC), tendo sido realizado uma importante modificação conceitual no que tange a percepção do ´objeto de trabalho´ ao longo de todo o sistema produtivo do EAS. As modificações que ocorreram, sob a égide e foco na Função Processo, foram centrais para a criação e melhoria dos fluxos produtivos em todo o sistema de produção. Visando a sustentação das mudanças ocorridas na Fase III, ocorreu uma ampla reformulação no modelo de gestão com a criação do conceito de Fábricas (Blocos, Pintura e Edificação) que passaram a ter gestores específicos responsáveis pelas melhorias incrementais e radicais dos fluxos produtivos. Além disso, foram realizadas ações no que tange à Função Operação: i) implantação do conceito de Gestão do Posto de Trabalho nas máquinas restritivas do corte; ii) gerar várias linhas de produção utilizando o conceito de box, com uma visão mais geral de fluxo oriundo da ótica do Tambor/Pulmão/Corda da TOC, com a utilização intensiva do conceito de Operação-Padrão para o dimensionamento dos mesmos. Ainda, através de um relatório de uma consultoria coreana, foi possível entender um conjunto de gaps existentes entre o modelo de sistema de produção atualmente adotado na empresa em estudo e o benchmarking coreano. A partir desta perspectiva evolucionária histórica de desenvolvimento do sistema produtivo do EAS, o trabalho propõe a adoção de uma série de boas práticas no intuito de aprimorar os processos na empresa em estudo. Finalmente, a título de conclusão, a aplicabilidade dos conceitos de engenharia de produção na indústria naval, tem impacto direto em termos das melhorias econômico-financeiro da empresa. / This case study deals with the evaluation of the use of the best practices of Production Engineering in the naval industry, having as background the Estaleiro Atlântico Sul (EAS). It is a descriptive and explanatory case study. The project describes the evolutionary trajectory of the EAS Production System, characterizing it in three distinct phases. In Phase I, which begins in 2008 and extends until July 2014, it is identified a significant influence of the historical factors of the naval production in Brazil that had strong influence of the Taylorist / Fordist paradigm, and can be synthesized by the fact that the production of ships was perceived as a ' construction ' with the management of the several ‘disciplines’. Phase II, which occurred between July 2014 and January 2016, constituted a transition phase that had as its central element the goal of modifying the organizational culture of the company, which was accomplished through the adoption of concepts such as: 5S, mini factories and Kaizens focused on improving production flows and process-focused quality. And in Phase III, which begins in January 2016, has as a critical event the creation of a full-scale EAS model that aims to create a holistic view of the company and the production system. Phase III has as its theoretical basis the Toyota Production System and the Theory of Constraints (TOC), and an important conceptual modification was made regarding the perception of the 'work object' throughout the EAS production system. The changes that occurred under the aegis and focus on the Process Function were central to the creation and improvement of production flows throughout the production system. In order to sustain the changes that occurred in Phase III, there was a broad reformulation in the management model with the creation of the concept of Factories (Blocks, Painting and Edification) that started to have specific managers responsible for the incremental and radical improvements of the productive flows. In addition, actions were taken with respect to the Operation Function: i) implementation of the concept of Workstation Management in the restrictive cutting machines; ii) generate several production lines using the box concept, with a more general view of flow from the TOC Drum / Buffer / Rope perspective, with the intensive use of the Standard Operation concept for their design. Also, through a report from a Korean consultancy, it was possible to understand a set of gaps between the production system model currently adopted in the company under study and the Korean benchmarking. From this evolutionary historical perspective of the development of the EAS production system, the paper proposes the adoption of a series of good practices in order to improve the processes in the company under study. Finally, as a conclusion, it seems possible to affirm the adherence and applicability of the concepts of production engineering in the naval industry, and its application has a direct impact in terms of the company's economic and financial improvements

It is of vital importance never to forget that the world is ever changing. Therefore, it is crucialfor organizations not to only alter but also to improve their performance in order to becomemore competitive on the market. One way of achieving this is to work with continuousimprovements. However, this requires that the employees receive the needed training for thispurpose. In multinational corporations they must also all receive the same training in order tocreate a common culture throughout the whole organization. This study therefore aims toinvestigate how a multinational corporation can organize an Improvement ManagementTraining. Which are the main areas that are desirable to have knowledge in when leading animprovement work? In order to identify the areas of interest, a case study has been performedat Ericsson Supply Site Borås. The investigation was conducted as a combination of aqualitative and a semiquantitative study in order to determinate the empirical data. The resultsrevealed that the following five major areas are essential for an Improvement ManagementTraining: Leadership, Lean¸ Organizational Behavior, Project Management and StrategicManagement. / Program: Bachelor of Science with a Major in Industrial Engineering – Work Organization and Leadership

O presente trabalho levanta questões sobre algumas formas particulares de estruturação de um sistema profissional de produção cultural para as artes plásticas no eixo Rio de Janeiro São Paulo no período que coincide com um momento de florescimento político e econômico e se fortalece a partir da segunda metade dos anos 1940 e ao longo das décadas de 1950/1960. No que concerne especialmente aos museus de arte moderna, observou-se um fortalecimento institucional em torno do qual o sistema artístico brasileiro se estruturou. Para se chegar a essa conclusão foram analisados os aspectos estruturais (econômicos e políticos) centrados no eixo Rio de Janeiro São Paulo, e conjunturais, a partir das particularidades do fenômeno da arte da vanguarda construtiva brasileira. Foram consideradas as visões dos artistas nacionais em relação tanto à questão da arte de vanguarda como na sua relação com o museu. Consideramos, também, a Bienal como instituição, seu vínculo com os artistas e com o próprio MAM/SP no processo de divulgação da arte. Avaliamos a ação artística, peculiar pela presença das vanguardas construtivas, que envolvia grande participação dos artistas no cotidiano museológico. Além disso, consideramos o estreito diálogo que havia com os críticos que atuavam em veículos de comunicação. Como parte fundamental do estabelecimento de um sistema profissional de produção cultural, avaliamos a consolidação de um mercado de arte com base na atuação de marchands e na criação de galerias privadas em uma ação ainda não muito distinta daquela dos museus. Os movimentos concreto e neoconcreto, na medida em que se caracterizam como vanguardas artísticas e sua atuação permitiu a mobilização do suposto sistema em torno das discussões sobre suas novas propostas éticas e estéticas, foram considerados pontualmente. / This thesis raises issues on some specific ways of structuring a professional system of cultural production for the arts in the circuit Rio de Janeiro São Paulo coincident to a moment of political and economical emergence that gets stronger from the middle of the 1940s and during the 1950/1960 decades. Regarding in special the museums of modern art, it was observed an institutional strengthening around which the Brazilian artistic system was structured. To reach that conclusion structural aspects the economics and politics in the circuit Rio de Janeiro São Paulo as well as situational ones were considered on the specificities of the phenomenon of the Brazilian constructive vanguard art. We also considered the vision of the national artists on the art of vanguard and its relation to the museum. Also, we considered the Bienal and its relation with the artists and with the Museum of Modern Art of São Paulo itself in the process of divulging the art. We evaluate the artistic action, peculiar because of the presence of the constructive vanguards, and that involved a great participation of the artists on the museum day-to-day. Besides that we consider as well the close dialogue with the critics who worked on the vehicles of mass communication. As a fundamental part of the establishing of a professional system of cultural production, we evaluate the consolidation of an art market based on the activities of the dealers and the creation of private galleries in one action not yet very much distinct from that of the museums. The concrete and neoconcrete movements were specially considered because as artistic vanguard, their performances enabled the mobilization of the supposed system around the discussions on its new ethical and aesthetic proposals.

Dans cette thèse nous analysons dans quelle mesure le concept de mobilité peut être pris en compte dans la démarche d'analyse et de conception de systèmes de production. Notre apport vise à formaliser la démarche d'analyse et de conception de ce dernier, explicitant les décisions à prendre, les informations nécessaires et les critères de décision à mettre en place. Dans cet objectif, deux niveaux d'analyse ont été distingués : un niveau local concernant un site de production et un niveau global comprenant un ensemble de sites.Le premier niveau local considère un seul site de production. A ce niveau nous avons proposé une approche prenant en compte les caractéristiques du site de production. Dans notre contexte, le choix de la localisation géographique de production est imposé par le client. De ce fait, la conception du système de production doit s'adapter à cette contrainte. D'un point de vue conception, quatre questions sont abordées : (1) dans quelle mesure le concept de mobilité peut être intégré dans une démarche de conception de système de production mobile ? (2) quelles caractéristiques de l'environnement de production doivent être prises en compte ? (3) comment déterminer ce qu'il faut produire sur site ou ce qu'il serait opportun d'externaliser ? et (4) compte tenu des informations obtenues quelle est la meilleure configuration du SPM à envisager et selon quels critères de choix ? La réponse à ces questions conduit à la proposition d'une configuration du SPM adaptée pour un seul site de production.Le deuxième niveau global traite la problématique de mobilité successive multi sites. En effet, pour être rentabilisé le système de production doit être mobilisé sur plusieurs sites de production. A chaque changement de site de production, une reconfiguration du système de production s'impose en se basant sur la configuration existante (version i-1). LaThèse de Youssef BENAMAreconfigurabilité concerne d'une part l'architecture interne du système (choix des machines, recrutement de nouvelles équipes locales, etc) et d'autre part l'organisation de la chaîne d'approvisionnement du SPM (faire en interne ou externaliser, fournisseur local, etc.). A ce niveau global d'analyse, nous proposons deux modèles d'analyse : (1) un premier modèle pour l'analyse de la reconfigurabilité interne. Ce modèle d'analyse permet d'adapter le nombre de lignes de production et le nombre d'équipes en fonction d'un scénario de demande (localisations géographiques, capacité nécessaire par site). L'originalité de notre proposition consiste d'une part en l'évaluation des coûts de reconfiguration nécessaires et d'autre part l'appréciation du niveau d'adéquation de la configuration proposée avec le contexte du site de production via l'utilisation de l'indicateur de mobilité. (2) Le deuxième modèle d'analyse concerne la reconfigurabilité de la chaîne d'approvisionnement amont du SPM. Il consiste en une adaptation du modèle d'aide à la décision "faire ou faire faire" par l'intégration d'un côté de l'importance du site de production et d'un autre côté des spécificités de chaque site de production.La démarche d'analyse proposée est illustrée sur le cas industriel concernant la conception d'une usine mobile pour la fabrication et l'installation sur site de composants de centrales solaires thermodynamiques. / In this thesis we analyse how the concept of mobility can be taken into account in the analysis and design of production systems. Our contribution aims to formalize the analysis and design process, explaining the decisions, the necessary information and decision criteria to be taken into account. For this purpose, two levels of analysis were distinguished: a local level concerning one production site and a global level including a set of sites.The first level considers one production site. At this level we have proposed an approach that takes into account the characteristics of the production site. In our context, the choice of the geographical location of production is imposed by the final client. Therefore, the design of the production system should be adapted to this constraint. From a design perspective, four questions are addressed: (1) To what extent the concept of mobility can be integrated into a mobile production system design approach? (2) What characteristics of the production environment must be taken into account? (3) How to determine what to produce on site or that it would be appropriate to outsource? And (4) taking into account all obtained information what is the best configuration of the mobile production system to consider and according towhich criteria? The answer to these questions led to the proposal of a configuration of SPM suitable for a single production site.The second Level of analysis addresses the problem of global mobility. In order to be profitable, the production system must be used on several production locations. every change of production location led to a need of reconfiguration of the Production System. Reconfigurability Concerns the internal architecture of the system (machine selection, recruitment News local teams, etc.) as well as the organization of the SPM supply chain. Fot this global level, we propose two analytical models: (1) the first model for the analysis of internal reconfigurability. This analysis model is used to adapt the number of production lines and the number of teams according to a production scenario (Geographical locations, necessary capacity per site). The originality of our proposal consists on the assessment of costs to support reconfiguration and the appreciation the convenience level with the context of the production site by using the mobility indicator. (2) Second model to analyse Concerns reconfigurability of the upstream supply chain of PMS. It Consists in June adaptation of the model using the decision "to do ou do" by integrating A side of the importance of the production site and another side Specifics Each of the production site.The proposed approach is illustrated on an industrial case concerning the design of a mobile manufacturing plant used to produce in-site and Install components of solar plant

The Technician department (MST) at Scania Chassi in Södertälje believes that SPS can streamline the technicians work and help them become a more homogeneous group.   The purpose of this master thesis is to initiate an implementation of SPS within MST through two pilot projects involving both the product and process technicians. The SPS principle Normal Situation - Standardised working method was required to be implemented within one work task each for the two groups of technicians with special attention on the three subprinciples Standardisation, Takt and Balanced flow.   The master thesis fulfilled its purpose as the two pilot projects initiated the implementation of SPS within MST and the three sub-principles Standardisation, Takt and Balanced flow were implemented within the two chosen work tasks. An improvement of the new work procedure for the work tasks was also noted.   Following the completion of the thesis, it could be established that SPS can be implemented on almost all of the technicians work tasks, and therefore the chances are good for continuous implementations of SPS within MST. / Föreliggande rapport är resultatet av ett examensarbete vid Linköpings tekniska högskola och Uppsala universitet utfört på uppdrag av Chassimonteringen vid Scania CV AB i Södertälje.   Scania har sedan början av nittiotalet haft ett nära samarbete med Toyota ur vilket bland annat filosofin Scanias Produktionssystem (SPS) har utvecklats, som beskriver Scanias värderingar, principer och prioriteringar.

Industrialization of construction is a business strategy to significantly improve competitiveness. However, the organization structure of the construction firms needs to support the new production system. The knowledge on why and how this business development can be accomplished is scarce, both within academia and in business practice. This research seeks to fill this knowledge gap. The purpose of organization structure and the production system have is to coordinate the firm’s processes and control the work performing resources. Information is one of the most fundamental dimensions for steering and controlling the work. The different information types are determined by the firm’s product customization strategy and the production system flexibility. Further, diverse information types are managed in different extent by the organizational steering mechanisms. Consequently, firms with dissimilar customization strategy or production flexibility should organizationally be designed differently in order to be efficient. The developed model identifies four generic production topologies: “engineer-to-order” (ETO), “manufacture-to-order” (MTO), “assembly-to-order” (ATO), and “make-standard-products” (MSP). The differences between the topologies can be related to the location of the “customer-order-decoupling-point” (CODP) in the product realization process; and to what extent the upstream and downstream processes continuously use stored information or process information to accomplish the work of each product order. The model predicts which organization structure mechanisms that should be used for which processes for each production topology. It is the specific configuration of the mechanisms that gives each production topology their organizational capability. The model has been validated by case studies in four organizations, each representing one of the four generic production topologies. Three cases considered housing and one studied truck manufacturing. It has been shown that the conventional housing firms have an ETO-production topology, while industrialized housing firms belonging to one of the others, i.e. MTO, ATO or MSP. The reason is that ETO-firms rely on crafts-based production to manage the work, while the other topologies base their steering mechanisms on industrial principles. These two types of production are fundamentally different, which also explain the need for different organization structures. The research complements previous knowledge and significantly increases the ability to predict, analyze and explain an organization’s design and behavior. The model can be used in practice to guide business development work and performance improvement programs. / <p>Research funder: SBUF (The development fund of the Swedish construction industry).

Nowadays usage of advanced production equipment becomes more common among production industries, future challenges in the market require flexibility in production industries due to growing competition and demand responses. Decisions regarding acquisition and replacement of production equipment have a major role in future profitability and competitiveness of production industries. Production equipment life cycle is dependent on technical, economical and conceptual lengths of life. Technical and economical lengths of life are connected to production equipment and the conceptual length of life is connected to production systems. Acquisition and replacement assessment processes of production equipment within production industries require involvement from different responsible departments. Varieties of perspectives differ from different departments in their prioritization regarding economical, technical and conceptual lengths of life. Lack of collaboration and evaluation of critical factors create quality and capacity issues in production industries. This project is directed to investigate issues concerning establishment of a sustainable long term thinking in consideration of economical, technical lengths of life of production equipment and also conceptual length of life of production systems in an earlier stage of acquisition and replacement assessment processes. Investigated research questions in this project are the following; What is the correlation between lengths of life of production equipment &amp; production systems and how they influence each other? What is the basis for acquisition and replacement assessment of production equipment? How does buyer-supplier relationship influence length of life of production equipment? This thesis work is based on both theoretical and empirical findings. A case study was performed with a survey and interviews to gather data for the analysis. Technical and conceptual lengths of life are both based on economical profitability and have to be adapted to product generations. Expensive investments in production equipment are critical and can be risky for production industries if marketing experts are excluded or if future product generation forecast are not considered in production equipment acquisition processes. Information and knowledge inputs from production equipment suppliers have to be considered in an earlier stage of concept development in production systems. / Nuförtiden blir användandet av avancerade produktionsutrustningar allt vanligare inom produktionsindustrin, framtida utmaningar i marknaden kräver flexibilitet inom produktionsindustrin på grund av växande konkurrens och respons på efterfrågan. Beslut gällande anskaffning och utbyte av produktionsutrustningar spelar en stor roll i produktionsindustrins framtida lönsamheter och konkurrenskraftighet. Produktions-utrustningars livscykel är beroende av teknisk, ekonomisk och konceptuell livslängd. De tekniska och ekonomiska livslängderna är kopplade till produktionsutrustningar medan den konceptuella livslängden är kopplad till produktionssystemet. Bedömningsprocessen vid anskaffning och utbyte av produktionsutrustningar inom produktionsindustrin kräver delaktighet från olika ansvariga avdelningar. Perspektiv variationer och prioriteringar gällande ekonomisk, teknisk och konceptuell livslängd skiljer sig mellan olika avdelningarna. I brist på samarbete och utvärderingar av kritiska faktorer skapas kvalitets- och kapacitetsproblem inom produktionsindustrin. Detta projekt utreder problem gällande etablering av ett hållbart och långsiktigt tänkande med hänsyn till ekonomisk och teknisk livslängd av produktionsutrustningar samt konceptuell livslängd av produktionssystemet i ett tidigare skede av bedömnings-processen. Följande forskningsfrågor har undersökts i detta projekt: Vilken effekt har olika livslängder på produktionsutrustningar samt produktionssystemet, och vad har de för koppling? Vad är grunden för anskaffnings- och utbytesbedömningar av produktions-utrustningar? Hur inverkar relationen mellan köpare och leverantörer på livslängden av produktionsutrustningar? Detta examensarbete är baserat på både teoretiska och empiriska undersökningar. En fallstudie genomfördes med en enkät och intervjuer för att samla in data till analysen och besvara forskningsfrågorna. Den tekniska och konceptuella livslängden är båda baserande på ekonomisk lönsamhet och måste anpassas till produktgenerationer. Dyra inverteringar i produktions-utrustningar är kritiska och kan vara riskabla för produktionsindustrin om marknads-experter är uteslutna eller om framtida produktgenerations prognoser inte beaktades i anskaffningsprocessen. Information och kunskap från leverantörer av produktions-utrustningar måste beaktas i ett tidigt skede vid konceptutveckling inom produktions-system.

This study evaluated the lactation curve shape, the yield and composition of milk from cows of Holstein and Jersey breeds grazing annual ryegrass (Lolium multiflorum) in northwestern Rio Grande do Sul, and aimed to analyze its response when subjected to grazing pasture herd consisting of two genotypes. The experiment was conducted from 08.18.2010 to 10.29.2010 and are used in total, eleven tester cows of each racial group and a variable number of regulator cows. The animals were managed in rotational grazing with variable stocking rate and were supplemented at a rate of 1 kg per 3 liters of milk produced above 15 liters / cow / day. Pasture management allowed similar grazing conditions between the two tested breeds and proved to be not limiting to pasture and animals production. Individual milking performance was measured once a week throughout experimental period. The visual body condition score (BCS, 1-5), was also registered weekly, and body weigh was measured monthly. The experimental design for pasture variables and for individual animal production was a randomized block design with replications in time, having been used stepwise proc (SAS, 2009) to test regression models. Only the supplement in the months August, September and October in analysis, besides individual productions corrected to 4% fat, day consuption in the months of August, September and October was considered in analysis, besides individual animal productions corrected to 4% fat, days in lactation period , body weights, BCS, number of lactations and age. Individual samples were taken by milking in September and October, and analyzed for the following milk components: fat, protein, lactose, water, acidity, freezing point, density, and computed total dry extract (TDE) and defatted dry extract (DDE). The statistical analysis for milk components was randomized complete blocks with triple factorial arrangement for breeds (2), periods (2), and stages of lactation (4). ANOVA was performed by GLM (SAS, 2009) and multivariate analysis, through Software Multiv (Pillar, 1997), using the correlation between variables as a measure of similarity, and clustering criteria was the least variance of sum of squares Jersey exceeded Holstein (P <0.005) for fat (%) lactose (%) and protein (%); Holstein was exceeding Jersey (P <0.0001) for fat (kg), protein (kg) and TDE ( kg). Correlation studies showed a clear difference in the degree of association between genotypes for dry matter intake of feed, with lower association for Jersey genotype, Holtstein presented a higher and consistent dependence of intake throughout the experimental period, coinciding with pasture cycle. This trend may indicate greater efficiency of Jersey genotype in the use of pastures of high quality, obtained in the initial pasture phases. The regression studies indicated that supplement dry matter intake (partial R ²) in September explained 65.69% of milk production for Holstein breed, and supplement dry matter intake (partial R ²) in October explained 55.73% of milk production of Jersey breed. / Foram avaliados o comportamento da curva de lactação, e a produção e composição do leite de vacas das raças Holandês e Jersey em pastagens de azevém anual (Lolium multiflorum) no noroeste do Rio Grande do Sul, com o objetivo de analisar a resposta de dois genótipos de raças leiteiras, em pastoreio rotativo. O experimento foi conduzido de 18/08/2010 a 29/10/2010, sendo utilizadas, onze vacas testadoras de cada grupo racial e um número variável de vacas reguladoras. Os animais foram manejados em pastoreio rotativo com lotação variável e receberam concentrado comercial à razão de 1 kg para cada 3 litros de leite produzidos acima de 15 litros/vaca/dia. O manejo das pastagens permitiu condições de pastejo semelhantes entre as duas raças testadas e se mostrou não limitante à produção da pastagem e dos animais. Foi medido o desempenho individual por turno de produção de leite, uma vez por semana em todo período experimental. Também foram tomados semanalmente, o escore de condição corporal (ECC, escala de 1 a 5), e mensalmente o peso vivo (PV), em balança mecânica. O delineamento para variáveis da pastagem e produção animal foi blocos ao acaso, com medidas repetidas no tempo, tendo sido utilizado o proc stepwise (SAS, 2009) para testar modelos de regressões. Foi considerado apenas o consumo do suplemento nos meses de agosto, setembro e outubro na análise, além de produções individuais corrigidas a 4% de gordura, dias em leite no inicio e final, pesos, ECC, número de lactações e idade. Foram tomadas amostras individuais de leite por ordenha, em setembro e outubro, e analisados para os componentes: gordura, proteína, lactose, além de água, acidez, crioscopia, densidade, e calculados extrato seco total (EST) e extrato seco desengordurado (ESD). A análise estatística para componentes do leite considerou o delineamento em blocos ao acaso em arranjo fatorial triplo para raças (2), períodos (2), e fases de lactação (4). Foi realizada ANOVA por GLM (SAS, 2009) e análise multivariada, através do Software Multiv (Pillar, 1997), sendo utilizada a correlação entre variáveis como medida de semelhança, e o critério de agrupamento foi a variância mínima da soma de quadrados. Jersey foi superior a Holandês (P<0,005) para os teores de gordura (%) lactose (%) e proteína (%); Holandês foi superior a Jersey (P<0,0001) para as produções de gordura (kg), proteína (kg) e EST (kg). O estudo de correlações indicou clara diferença no grau de associação entre genótipos para consumo de matéria seca do concentrado (CMSR), tendo Jersey menor associação, e Holandês uma mais alta e consistente dependência desse consumo ao longo do período experimental, coincidente com o avanço no ciclo da pastagem. Esta tendência pode indicar maior eficiência do genótipo Jersey no uso de pastos de alta qualidade, obtida nas fases iniciais da pastagem. O estudo de regressões indicou CMSR (R² parcial) no mês de setembro explicando 65,69% da produção de leite do genótipo Holandês, e CMSR (R² parcial) no mês de outubro explicando 55,73% da produção de leite do genótipo Jersey.
