Abstract
The study evaluates the behavior of production and prices in the beef cattle market in Rondônia, Brazilian Amazon. Covering the period from 1995 to 2020, we used statistical analysis based on the classical multiplicative method of time series. Resultingly, we found that the occurrence of annual seasonality in prices, with a reduction in the first half of the year and an increase in the second half of the year, corresponding to the bovine and off-season harvests, respectively. It was possible to observe the existence of three complete livestock cycles, with an average duration of five years. Trend, seasonality, and cycles of livestock in Rondônia, over the last 25 years, expose a series of relevant information for decision-making by agents in the livestock production chain, in addition to contributing to the understanding of the dynamics of this important agricultural market for Rondônia and Brazilian economy.
