Item Efeitos da gestão no desempenho econômico e ambiental da pecuária de corte no Cerrado goiano(Universidade Federal de Goiás, 2022-04-28) Naves, Ana Carolina Alves Rodrigues; Jesus, Andrelisa Santos de; http://lattes.cnpq.br/9279471449282134; Souza, Cleonice Borges de; http://lattes.cnpq.br/8449949211640425; Souza, Cleonice Borges de; Cruz, Fabiana Thomé da; Santos, Patricia Guarnieri dos; Araújo, Fernando Moreira deThe lack of application of management methods in the productive activities of rural properties results in a limitation for producers to continue to produce with economic and environmental sustainability. Well managed and managed agricultural activities have the role of maximizing the profitability of the activity and minimizing environmental impacts. The management of the rural property is necessary to subsidize the permanence of the activity in the agricultural market, which represents the guarantee of producing food, using the strategy of sustainable competitive advantage. The objective of this work is to analyze the effects of management on the economic and environmental performance of rural properties in the micro-region of Pires do Rio-Goiás. This research is of an applied nature, with a qualitative-quantitative and descriptive approach, with artificial participant observation. It is also documentary, since it used secondary data from the SENAR+ Project, from a group of 23 rural properties that joined the Technical Assistance project dedicated to beef cattle, as well as the IBGE database (Censo Agropecuário, 2017). Data on the quality of pastures and the Rural Environmental Registry (CAR) were compared to verify the preservation of the legal reserve and Permanent Preservation Area (APP) before and during the execution of the project, via remote sensing evaluation with Planet images, which guarantees 5m accuracy using Google Earth Engine and QGIS. It was identified the existence of gaps regarding the management of productive activities, the resistance of the producers to the new production techniques and the remote sensing allowed to evidence changes in the quality of the pastures and the state of preservation of the legal reserves and APP, which are not preserved in its entirety, which generates inconsistencies about the environmental sustainability of these activities. It is concluded that pastures considered to be in a medium degradation stage do not generate profitability for producers.Item Influência dos preços dos principais grãos da alimentação de suínos no preço da carne porcina nos estados de Goiás, Minas Gerais e Paraná(Universidade Federal de Goiás, 2021-02-25) Oliveira Júnior, João Ricardo de; Figueiredo, Reginaldo Santana; http://lattes.cnpq.br/1098394550647665; Figueiredo, Reginaldo Santana; Wander, Alcido Elenor; Oliveira Neto, Odilon José deIn pig farming, animal nutrition is considered an important component of the production costs representing about 70% of rearing and fattening activity. This input is based on three important agricultural products: corn, soybeans and sorghum. That said, the knowledge of the interrelationships between inputs’ prices and other components of animal feed allows to draw some guidelines for planning and management of pig farmers especially for the decisions making that involve production that can expanding the possibilities of financial returns. Thus, the main objective of this master thesis was to analyze the influence of corn, soy and sorghum prices on the pork price in the states of Goiás, Minas Gerais and Paraná, Brazil. The methodology used involved verifying the behavior and order of integration of the variables. As well as, the investigation of the degree of magnitude and speed of adjustment of pork prices to highs and lows alterations in these commodities prices. In addition, the hypothesis of asymmetry in prices was verified. In the end, the causal relationship between prices was accurate. The econometric models used in this master thesis were Engle-Granger cointegration, ECM, TAR, M-TAR and Granger causality. Consequently, due to the common results found between the states of Goiás, Minas Gerais and Paraná, pork price respond equally to changes in the prices of corn, soy and sorghum, with similar behaviors in the long term. As well, that the short-term price path towards long-term equilibrium is slow, with the late transfer of corn, soybeans and sorghum prices of pork price. In addition, it has been assumed that a hypothetical increase in grain prices would lead to a significant increase in pork prices when using sorghum and soy in pig feed in Minas Gerais and Goiás, whereas in Paraná it would be when using corn and soy. Also, the corn price can be considered a good predictor for pork price in Minas Gerais and Paraná. In Goiás the pork prices are a good predictor for variations in sorghum prices. And in Paraná the pork price is established as a good predictor for variations in soybeans prices.
