A composição de ácidos graxos da dieta pode influenciar o desempenho produtivo e o sistema imune de frangos de corte. O objetivo deste estudo foi avaliar o efeito do consumo de óleos ricos em ácidos graxos poli-insaturados ômega-6 (PUFAs n-6) e ômega-3 (PUFAs n-3) sobre o desempenho e a resposta imunológica de frangos de corte frente a um desafio antigênico. Foram comparadas dietas formuladas com 7% de óleo de soja (OS), linhaça (OL) ou sardinha (OP), fornecidas a 240 frangos da linhagem Cobb, divididos em 24 grupos de 10 aves cada, num arranjo experimental 3x2 (3 tipos de óleo e aves vacinadas ou não vacinadas) e 4 repetições. O óleo de soja é rico em ácido linoleico, um PUFA n-6, o óleo de linhaça é fonte de ácido alfa-linolênico, um PUFA n-3, e o óleo de sardinha, de outros PUFAs n-3, como os ácidos eicosapentaenoico e docosahexaenoico. O consumo de ração, o ganho de peso e a conversão alimentar foram avaliados aos 21, 35 e 42 dias. Aos 7 e aos 21 dias de idade, metade das aves recebeu vacina contra doença de Newcastle. Quinze dias após a imunização, avaliou-se a produção de anticorpos pelo método de ELISA, expressa pela densidade óptica a 450 nm (D.O. 450nm). Apenas as aves alimentadas com ração contendo OS apresentaram maior imunidade humoral (P<0,05) após a vacinação. A resposta linfoproliferativa das aves, que expressa a imunidade celular, foi maior entre as aves vacinadas, em comparação às aves não vacinadas (P<0,05), independentemente do óleo utilizado. A fonte de óleo da ração ou a vacinação não influenciaram o ganho de peso das aves (P>0,05). Entre as aves que receberam dieta com OS, as aves vacinadas apresentaram pior conversão alimentar (P<0,05). Nos grupos que consumiram ração com OL ou OP, a vacinação não influenciou a conversão alimentar (P>0,05), considerando todo o período experimental. A utilização de óleo rico em PUFA n-6 na dieta de frangos de corte aumentou a resposta humoral, mas não influenciou a resposta celular frente a um desafio antigênico.

In a globalized world, organizations face an increasingly dynamic, innovative and competitive environment, so that this condition requires continuous adaptation to market developments. Intense competition requires organizations to further improve their performance, making productive efficiency a key factor for survival. A methodology that has added value to the product through a reconfiguration of the production method is the implementation of a management philosophy called Lean Six Sigma. The main objective of this work is, in the light of the Lean Six Sigma philosophy, intervene in a critical-collaborative way to develop procedures for analyzing the profitability of products in a company specializing in steel processing. To achieve this goal, were applied the method of action-research to intervene in a group of professionals for the study of the profitability of products in a auto parts industry. The interaction of practical and theoretical knowledge provided by the action-research allowed the business program was enhanced. The procedures proposed in this study were able to identify the current profitability of the product, the main causes of inefficiency and productive for solutions to reduce production inefficiencies, when the productive systems planned and actual production system were compared. The results indicate that current profitability of -3%, while the parameter provided during budget was 10%. Thus, it is concluded that the low profitability of the products may compromise the company's financial results and affect their competitiveness in the market. To address this problem, the Lean Six Sigma presents itself as a versatile and high applicability philosophy, providing relevant results for characterization and troubleshooting. It was also observed that the evidence presented in this paper can be adapted to other companies in the metal auto parts segment to identify and recover the profitability of products

The objective of this work was to evaluate the productive and reproductive performance of beef cows, as well as the performance of their calves according to the following dietary treatments: PRE: supplemented with protected fat (PF) during 45 days prepartum; PREPOS: supplemented with PF during 45 days prepartum and 63 days postpartum; POS: supplemented with PF during 63 days postpartum; PN: without supplementation. The productive performance of cows was not influenced by feed management (P>0.05), except for body condition score (BCS), which was lower for PRE and PREPOS cows at the end of mating season, with the latter cows having similar BCS POS and PN. The calving interval (CI) was shorter for cows supplemented in PREPOS - 376 days -, and did not differ in cows maintained in PN - 383 days. Supplemented PREPOS cows weaned 4.4% more pounds of calf per 100kg of cow at calving - 22.6kg - than the PRE and POS cows - 21.6kg and 21.6kg, respectively - and 8,4% more pounds of calf per 100 of cow at calving than the cows maintained in native pasture - 20.7kg. The fat protected supplementation during pre and/or postpartum periods did not affect the performance of cows and calves.

Companies are currently choosing to integrate logics and systems to achieve better solutions. These combinations also include companies striving to join the logic of material requirement planning (MRP) system with the systems of lean production. The purpose of this article was to design an MRP as part of the implementation of an enterprise resource planning (ERP) in a company that produces agricultural implements, which has used the lean production system since 1998. This proposal is based on the innovation theory, theory networks, lean production systems, ERP systems and the hybrid production systems, which use both components and MRP systems, as concepts of lean production systems. The analytical approach of innovation networks enables verification of the links and relationships among the companies and departments of the same corporation. The analysis begins with the MRP implementation project carried out in a Brazilian metallurgical company and follows through the operationalisation of the MRP project, until its production stabilisation. The main point is that the MRP system should help the company's operations with regard to its effective agility to respond in time to demand fluctuations, facilitating the creation process and controlling the branch offices in other countries that use components produced in the matrix, hence ensuring more accurate estimates of stockpiles. Consequently, it presents the enterprise knowledge development organisational modelling methodology in order to represent further models (goals, actors and resources, business rules, business process and concepts) that should be included in this MRP implementation process for the new configuration of the production system.
