In order to reach this goal it was analysed if there is a long-term relationship between the cattle prices in Rondônia and the Esalq/BM&amp;F Cattle Index. Besides that, it was done an examination of the optimal hedge Rio Branco – Acre, 20 a 23 de julho de 2008 Sociedade Brasileira de Economia, Administração e Sociologia Rural ratio and its effectiveness to the year of 2007.

he rapid growth in consumer demand for livestock offers an opportunity to reduce poverty among smallholder livestock farmers in the developing world. These farmers’ opportunity may be threatened, however, by competition from larger-scale farms. This report assesses the potential threat, examining various forms of livestock production in Brazil, India, the Philippines, and Thailand. Findings show that the competitiveness of smallholder farms depends on the opportunity cost of family labor and farmers’ ability to overcome barriers to the acquisition of production- and market-related information and assets. Pro-poor livestock development depends, therefore, on the strengthening of institutions that will help smallholders overcome the disproportionately high...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Peres,   Fernando Curi; de Zen,   Sergio; Ambrosio,   Luis Alberto; Ichihara,   Silvio M.
Using the technique of "panels" farms were drawn as representatives from three regions of Brazil: the first was a medium size farm representing the grain production area of Northern Rio Grande do Sul State; the second, a large farm from the grain and livestock production area of Mato Grosso State; the third, a very large farm from the Amazonian livestock production area of Para State. The long-term cost of production was estimated and the yearly average net income was evaluated for each typical farm. An "energy" evaluation table, prepared according to procedures described by Odum (1996), was used to estimate each farm process of incorporating energy into its production as a way to evaluate the sustainability of the farms systems. A four quadrant reference...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: de Zen,   Sergio; Peres,   Fernando Curi; Barros,   Geraldo Sant'Ana de Camargo.
The objective of this study is to show the importance of diversification in the risk management process. The study areas are: Mato Grosso, with large properties, and Rio Grande do Sul with small. The developed activities are annual cultures and cattle for slaughter. The hypotheses of the work are: a) rural producers diversify their activities using modern techniques. b) Diversification has been efficient in the producers' risks reduction. c) Producers tend be as effective as possible, though they differ in the rates of risk aversion. The MOTAD and E-V models were used.
