This work analyses the historical evolution of prices paid to farmers of main animal derived products from the state of Rio Grande do Sul for the last three decades, emphasizing tendencies that occurred since the 90s, and mainly after the monetary stabilization obtained in 1994 with the "Plano Real". This study was based on records of median monthly prices paid to the farmer, collected by Emater/RS, considering the period since January 1973 until December 2004. The analysis concluded that all of the products considered (beef cattle, sheep and pork meat, poultry, eggs and milk) presented a significant decrease in their real price value between 1973 and 2004, with decreasing tendency up to 1994, being that the period between the beginning of the 80s and midst 90s was the one with the highest decrease in prices. Furthermore, it was concluded that the period after the "Plano Real" was characterized by real price stabilization in most of the studied products, except sheep derived products, which presented a tendency to increase prices during this period.
