Aiming to analyze if the boundaries the firm (soy producer) were altered due to technological changes (GMO soy). The evolution of soy production was compared and related to: the use of credit loans for covering costs; the amount of contracts related to rural loans; and the area for farming soy using rural credit. The results confirm the “Penrosian ” conceptual, that the decreasing incomes may be overcome by the firm’s capacity to adapt its structure to new production conditions. So, it is possible to state that soy producer in Brazil were benefited with the opportunities brought about by the technological economy.

Os resultados demonstraram certa desestruturação organizacional da cadeia produtiva, decorrente da dificuldade no fluxo de informações entre os agentes e os elos produtivos. Entretanto, o mercado apresenta potencial de crescimento, principalmente se as ações estiverem direcionadas à diferenciação e à agregação de valor, com foco em mercados específicos, marketing responsável e coordenação dos processos produtivos.

The concept of return on investment was used to develop the indicator. Scenarios regarded as efficient showed values higher than 3. The bioeconomic efficiency index for beef cattle production in the theoretical reference scenario was considered inefficient. At least four modifications in the variables method made it a bioeconomically efficient activity. These circumstances were studied using sensitivity analyses, with theoretical changes in the scenarios by changing variables two by two, while the others were kept constant. In Rio Grande do Sul, alternatives that make the activity efficient were identified by changing productivity, production cost, land price and product price. Isoefficiency relationships were identified in other scenario...

An alternative may be the direct commercialization to consumers. Current analysis studies the commercialization channels used by beef and pork Brazilian rural agroindustries and reports on the representation of direct sales of these establishments in Brazil and in each region. A review of the literature was undertaken coupled to a statistical investigation of the 2006 Cattle and Agriculture Census. Results show that direct sales are the main channel of commercialization used by rural meat agro-industries. On a lower scale there is the commercialization by middlemen, industries, integrated industries, cooperatives and the government. Direct sales are an opportunity to obtain aggregated value for agricultural products more in line with the northern and northeastern regions of Brazil

Current essay presents a historical analysis on the strategies adopted by world organizations by identifying challenges in agribusiness related to food safety. The exploratory and qualitative analysis evidenced food challenges, related to agricultural and cattle-breeding activities, to the environment and social questions and to activities and technologies that contribute towards a more sustainable production. Results show one of the greatest challenges in the field during the 21 st century, or rather, the development of a doubly green revolution, with dynamic and structured features, aiming at progress. The development of biotechnology has embodied techniques and practices that minimize environmental impacts. Specific studies contribute towards genetic improvement (vegetal and animal) and provide food production in place...

However, in Rio Grande do Sul State, production of cow-calf have low reproductive and financial indexes. In this way, farmers should improve their technological and management capacity to optimize its production. Furthermore, programs to promote high livestock production are routinely challenged in beef cattle production to yield substantial information for farmers to be used form its well development in the system activity. This work is divided into two main goals. In the first study, factors that differentiate the farmers were compared in relation to weaning rate and to adopt technologies. This survey comprehends 73 farmers and 48 technologies. We used multivariate data analysis, comprising the GLIMMIX procedure, Tukey test, FASTCLUS procedure, discriminant analysis (DISCRIM and STEPDISC) and chi-square test to evaluate the collected data.

Data analysis was performed using descriptive statistics and discriminant analysis, complemented by stepwise regression, Wilks’ Lambda test, and Fisher’s linear test. Most of the respondents expressed that inadequate commercialization of meat occurred in free fairs, and the lack of hygiene and [...]

Subsequently, we also verified the socioeconomic and productive characteristics related to the adoption of technologies to increase the weaning rate of the farmers. The survey was conducted with 73 producers of Hereford and Braford cattle in the state of Rio Grande do Sul, Brazil. A data analysis was performed using the minimum ordinal squares method and the regression analysis (Tobit). The results showed that cattle farmers who adopt winter pastures have greater weaning rates, and the factors that influence this adoption are related to a greater number of employees on the farm and the use of a crop-livestock production system. In addition, farmers who receive a greater number of technical assistance visits per year are more likely to adopt winter pastures and improved native grassland. This information can be useful in the formulation of technological dissemination programs that aim at a sustainable production of beef cattle.

Thus, we propose an analytical method for estimating productivity and understanding the importance of animal production indicators under different full-cycle cattle production systems in Brazil. To evaluate the impact of these indicators, equations were derived from a comutational model of herd evolution for estimating the output parameters of the system as follows: productivity per hectare (PH) and offtake rate (COR), as a function of the indicators; calving rate (CR), mating age (AM), age of slaughter (AS) and stocking rate (SR). For this analysis, twenty-seven scenarios (simulation data) of low to high productivity were used, resulting from the combination of the following factors and levels: 1) calving rate of 50, 65 and 80 %; 2) mating age of heifers of one, two and three, years of age; and 3) age at slaughter of one, two and three year old steers. The scenario with the highest impact for each parameter and the indicator of highest impact for each scenario were identified for the production conditions in the region. Under most scenarios, a reduction in mating age had a greater impact on the productivity indexes compared to a reduction in slaughter age. Appropriate management of available technologies enables farmers to compare the marginal impacts of specific indicators on full-cycle production systems for beef cattle.

A survey was conducted with 33 beef cattle farmers operating with complete cycle production systems in areas larger or equal to 900 ha. Answers were classified in two drivers, technology (TEC) and management (MAN), which were separated into subfactors with their respective components. Multiple correspondence analysis, Tukey test, cluster analysis, and Pearson correlation were the statistics procedures. The TEC components were above normal for Brazilian farmers, but the gross margin is still lower than that needed to generate financial resources for a proper remuneration of cattle farmer. Farmers were classified into three clusters according to bioeconomic efficiency: low (LEL), intermediate (IEL), or high-efficiency level (HEL). The TEC driver differentiated the LEL x HEL clusters and the MAN, mainly expressed in costs, the IEL x HEL. Positive co...

The perception of 18 experts on animal sciences regarding the risks of 32 nutritional, breeding, and general management practices applied to increase pregnancy rate were evaluated through questionnaires. The experts were selected by a non-probability sampling of researchers on veterinary and animal sciences. In addition, five farmers and eight technical consultants were also selected. The questionnaire was applied during a face-to-face meeting. The risk of each practice was assessed according to four factors, namely, cost, technical knowledge, operational complexity, and flexibility, and an equation was developed to calculate this risk. The applied method allowed to determine the risk of each practice, obtaining results similar to those previously perceived by the experts. Operational complexity and cost had greater influence on the estimated risks compared with the other factors. Moreover, the increase of one unit in operational complexity and cost increased the perceived risk and the estimated risk scores in 0.43 and 0.28 points, respectively. Overall, the application of general management practices presented lower risk score compared with nutritional and breeding practices, which were not different from which other. Equations to estimate the risks of farm managers should routinely apply management practices to increase the efficiency of cow-calf production systems.

As novas tecnologias e a gestão de recursos naturais surgem para evitar desperdícios e adequar sua utilização. Frente a esta problemática, este artigo busca esclarecer os conceitos referentes à água e seu agronegócio, propondo uma visão ampla da questão e tentando aproximá-la do agronegócio brasileiro. Assim, é possível observar que em todos os produtos comercializados, desde alimentos, peças de vestuário e aparelhos eletrônicos, existe um consumo de água que não é demonstrado ao consumidor na embalagem, omitindo o verdadeiro impacto hídrico daquele produto. A pegada hídrica e terminologias, como a água virtual, são ferramentas que contribuem para amenizar problemas de escassez de água em diferentes regiões do mundo por meio do comércio internacional.
