In 1954, it was celebrated the centenary of railways in Brazil. The date refers to the first section of 14.5 km of railway in Brazil (30/04/1854), in Rio de Janeiro, between Mauá and Fragoso, of the Petropolis Railway Company (Estrada de Ferro Petrópolis). Some of the texts and commemorative events indicated the symbolic values that the railroad took in the Brazilian history. Firstly, on 30.04.1954, the railway section Mauá-Fragoso and steam locomotive “Baroness” (the first used on the track) were declared national monuments(Decree No. 35,447-A, April 30, 1954). Secondly, some entities (Clube de Engenharia, Conselho Nacional de Geografia, Ministério da Viação e Obras Públicas) highlighted the importance of celebrating the Brazilian railway history and its historical significance, economic and geographical. For this, some events was occurred (the commemoration of one hundred years in Rio de Janeiro and Recife on 30.04.1954). Among the texts wrought produced, we highlight the text I Centenary of Brazilian Railroad (1954), released by the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística), and the National Council of Geography (Conselho Nacional de Geografia). The emphasis given to the railway refersto the geographical perspective (territorial expansion), but also makes mention of the Barãode Mauá, the founder of Petropolis Railway Company. We aim to understand the celebration from evocations about the Brazilian railroad history and some ideas that is assigned to the railway (and the Barãode Mauá), and railway heritage (the track and the locomotive “Baroneza”). On basis of this review will seek to understand how it was reconceived the railroad memory in view of these values and material elements.

Two experiments (E) were carried out with the objective of evaluating the effects of fumaric acid and carbo-amino-fosfo-quelato of calcium diets of weaned pigs on performance (E1) and intestinal morphology (E2). A total of 96 and 32 pigs with initial mean weights of 5,66 kg ± 0,44kg and 5,34 ± 0,45kg , in E1 and in E2, were used respectively. Randomized block designs were used in both experiments, with a 2 X 2 factorial arrangement in E1 and a 2 X 2 X 2 factorial arrangement in E2. No interaction between acidifier, source of calcium and phosphorus were found for the variables studied in the two experiments. No treatment effects were found on daily feed intake in evaluating periods. Feed conversion from 0 to 17 days was better (P<0.05) when inorganic sources of Ca and P were fed; however, no difference was observed in other periods. The averages of villus height (AV), crypt depth (PC), AV: PC relationship and mucous membrane of the duodenum and of the jejunum didn’t differ among treatments. Considering the total nursery period, no benefit was found in using an acidifier, however the carbo-amino-fosfo-quelato of calcium studied may replace the inorganic sources in the diets of piglets, with no damage to performance and to intestinal morphology.

The objective of this study was toevaluatethe effect of the co-digestion of triturated sugarcane with beef cattlerfeddlotmanure in continuous digestorsin the amount and quality of biogas and biofertilizer. To do so, the work was divided in three steps. The first and the second part lasted30 days each and evaluated the effect of the additionof 7% of triturated sugarcane in agreement with the followingtreatments:treatment, the digestors were supplied with a mixture of 0,250 kg of manure and 1,750 kg of water ;treatment 2, the digestors were supplied with a mixture of 0,250 kg of manure, 1,610 kg of water, and 0,140 kg of triturated sugarcane. To The third period lasted 30 days and evaluated the effect of adding 3.5% of sugarcane crushed. The data analyses was performed with randomized designusing SAS®program with level of significance of 5%. The digesters with sugarcane produced in the first period respectively 0.79, 0.0127, and 0.102 m3of total production, of biogas production per kilogram of substrate, and of total production per kilogram of manure versus 0.5, 0.0081, and 0.065 m3from the control treatment, respectively..In the thirdperiod,each variable had a total production of 0.76, 0.123, and 0.98 m3and the control treatment yielded 0.51, 0.065, and 0.0082 m3.In the second period,the total production per kilogram of solidand of volatile solids added were higher in the digesters without sugarcane (0.0093 and 0.438 m3) when compared to the digesters that had additionof 7% of cane(0.271 and 0.336 m3).

O presente trabalho busca apresentar um método de balanceamento de ração (estudo de caso) que ofereça as exigências necessárias para o desenvolvimento de animais ruminantes, com diversas fontes de proteínas ao custo mínimo de produção para os produtores. Deste modo, o confinamento tem surgido como uma importante ferramenta para o pecuarista, que deseja ganhar em escala no seu sistema de produção e qualidade em seus produtos. Assim, a adoção de técnicas de manejo e alimentação que viabilizem a produção de carnes de melhor qualidade torna-se muito importante para colocar o setor pecuário em situação de igualdade com os grandes países produtores de carne. Para a realização deste trabalho, foi feito um levantamento bibliográfico e uma pesquisa de campo com o administrador de uma fazenda no município de Presidente Prudente-SP. Através dos resultados obtidos, pode-se verificar que neste estabelecimento têm diminuído seus lucros, principalmente em virtude dos altos custos da alimentação.
